Introduction It is well known and documented that changes in water quantity, timing and quality are introducing negative impacts to the Everglades ecosystem (Richardson et al., 1990; Walker, 1991 and 1995; Davis et al., 1994; Ligth and Dineen, 1994; McCormick et al., 1996; USFWS, 2000; Brandt et al., 2000; Raghunathan et al., 2001; Childers et al., 2003). Historically, the Kissimmee River discharged into Lake Okeechobee, and during wet cycles the lake would overflow its south bank, providing additional flow to the Everglades (Ligth and Dineen, 1994). Water, which once flowed in a broad swath across the Everglades, is now concentrated through canals, structures, and a series of water storage areas (Water Conservation Areas (WCA)). That water, when not used for municipal water supply or irrigation, is discharged to the Everglades National Park (ENP). According to the Comprehensive Conservation Plan for the Refuge (USFWS, 2000) “the construction of the levees has had significant effects on the hydrology, vegetation and wildlife in the refuge.” The U.S. Fish and Wildlife Service (USFWS, 2000) indicated that changes in natural timing of water levels affect wading birds feeding patterns, apple snail reproductive output, and alligator nesting. Similarly, changes in the spatial distribution of water levels alter the distribution of aquatic vegetation and tree islands. In addition, and particularly during the dry season, lower water levels increase the potential for fire and damage to vegetation, soils and wildlife. The USFWS in partnership with the South Florida Water Management District (SFWMD) and the U.S. Corps of Engineers are devoting considerable resources to restore and maintain appropriate water regimes for the Refuge. Along with the changes in water quantity and timing, the changes in water quality are an important threat to the Everglades ecosystem. High concentrations of nutrients (specifically phosphorus) in runoff from agricultural areas cause proliferation of cattails, and other undesirable species that negatively affect the ecosystem’s balance. Other negative impacts from increased nutrients include: increased soil phosphorus content, changed periphyton communities, loss of native sawgrass communities, increased organic matter in water, reduced dissolved oxygen, conversion of wet prairie plant communities to cattail, and loss of important habitats for wading birds (Stober et al., 1996). Along with ensuring an appropriate water regulation schedule, it is a priority for the Refuge to better understand and minimize the impacts of these excessive nutrient loadings. The purpose of the planned Refuge hydrodynamic and water quality modeling is to provide a quantitative framework for management decisions related to Refuge inflow and outflow quantity, timing, and quality. This modeling effort will provide projections of water movement and water quality resulting under alternative scenarios of structure operation, Storm Treatment Area (STA) performance, and structural changes within the Refuge. When fully calibrated and validated, the selected model should provide information and assist in answering questions on the hydrologic, hydrodynamic, water quality, and ecologic processes occurring under present conditions and management rules; and how these processes would be altered by different structural changes and management scenarios. For example: How different management scenarios (structural alterations, management decisions, strategies, and regulations) alter: o The hydrology. How will the spatial and temporal distribution of water inside the Refuge be altered? Will portions dry out and for how long? Is significant surface-groundwater interaction in the Refuge occurring? If so, what are the effects? o The hydrodynamics. How will near field hydrodynamics close to hydraulic structures be altered? How will far field current patterns be altered? o Water quality. How will water quality be altered? How will the spatial and temporal distribution of phosphorous inside the Refuge be altered? o The ecosystem. How will the ecosystem be affected by changes in hydrology? Will local changes in hydroperiod sustain the needs of desired plants and wildlife? It should be emphasized that the numerical model that will be developed is not a regional model. Therefore, it will not project the response of the natural system outside the Refuge’s boundaries to any alternations. It will however, provide detailed information about the response of the Refuge to regional management changes and alterations. This report focuses on data acquisition and processing, starting with the selection of the water quality constituents to be modeled and the selection of periods of records for calibration and validation. It assesses whether sufficient data is available to achieve the modeling goals. It also provides recommendation for monitoring where additional data is needed. The description of the Refuge’s background, hydrology, soils, physiographic, water management and regulation, as well as a comprehensive literature review of previous modeling efforts within the Refuge and wetland systems, will be presented in companion reports. 1.1 Objectives As indicated in the previous paragraph the main goals of this report are: • Identify the period of record for calibration and validation of the numerical model. • Identify the constituents to be modeled. • Compile the data needed to support the modeling effort. • Check the quality and resolution of the gathered data. • Determine if sufficient data is available to achieve the modeling goals. 2. Constituents to Be Modeled Since the everglades are oligotrophic-phosphorus limited systems (Childers et al., 2003; McCormick et al., 1996; Raghunathan et al., 2001; SFWMD, 2000), the discharge of excess amount of this nutrient will promote the eutrophication process and ecosystem imbalance, e.g., shifts in plant community composition. The 2000 Everglades Consolidated Report (2000 ECR) by the SFWMD indicated that the ratio of total nitrogen to total phosphorus (TN:TP) in the Refuge, increased from near 50:1 in the canal to near 150:1 in the marsh interior. Since values of TN:TP higher than 8:1 suggests phosphorus (P) limitation, the ratios for the Refuge are a clear indication that: (1) P is the more important limiting nutrient in both the marsh and canal waters; and (2) the severity of P limitation increases with increasing distance from the canal. The USFWS (2000) indicated that areas in the western, southwestern, southern and southeastern portions of the Refuge continue to be eutrophied by the influx of high nutrients runoff (specifically phosphorus) from agricultural lands. The hydrodynamic and water quality models being developed will be of value in testing this conjecture. According to Childers et al. (2003) water column total phosphorus concentrations in the Everglades are typically less than 10 mg/L. It is well documented that water flowing into the Everglades has an anthropogenic load of nutrients and other contaminants (e.g., Richardson et al., 1990, Stober et al., 1996; USFWS, 2000). Nutrient loading from urban areas and the Everglades Agricultural Area (EAA) has significantly increased nutrient concentrations, particularly phosphorus, in the water conservation areas (USFWS, 2000). Childers et al. (2003) reported that in northern Everglades regions, near to the EAA, total phosphorus concentrations often exceed 100 mg/L. Therefore, it is a priority for the Refuge to better understand the dynamics of nutrients on the systems, particularly of phosphorus, in order to minimize the impacts of this excessive nutrient’s loading. Total phosphorus in the sediments and in the water column is going to be modeled as a constituent in order to address this objective. It is important to accurately describe the hydrodynamic processes in order to determine and evaluate water quality impacts on wetlands (Mitsch, 1988; Mitsch and Reeder, 1991; Moustafa and Hamrick, 2000). The accurate description of the hydrodynamic often requires fine-tuning of certain model parameters, i.e., calibration, to match observed and predicted values, e.g., water surface elevations, water depths, water velocities, constituents’ concentrations, etc. After calibration, a validation process is usually conducted to ensure the model accuracy. However, the validation of velocities and transport subroutines are often not completed primarily due to lack of field measurements. To the best of the authors’ knowledge, there are no velocity measurements anywhere in the Loxahatchee Refuge. Therefore, a recommendation will be made to Refuge personnel to collect surface flow velocities in the rim canal as well as at interior sites. Although, the ability to model advection and diffusion can be assessed through modeling of conservative constituents, if deviation from the field measurements is observed, it would not be possible to determine whether the deviation is caused by error in the model’s advection or by the diffusion terms. It is believed that even a short term measurement of velocities at multiple locations within the Refuge will be of great value to this modeling effort. Traditionally, conductivity, total dissolved solids (TDS) and chloride have been used as conservative or semi-conservative tracers. Conductivity and TDS are highly correlated, and even though they are not fully conservative parameters, they can be used as such when high concentrations are present in the influent runoff/wastewater, assuming that wetlands have a negligible effect on these parameters. Kadlec and Knight (1996) indicated that wetlands have minimal effect on TDS. This is especially true because TDS concentrations are usually high in wastewaters and the individual components of these solids greatly exceed the biological requirements for growth. Kadlec and Knight (1996) recommended the use of chloride content as a tracer in wetland systems. They indicated that due to low biological demand, its abundance in surface water and its high solubility, the total mass of chlorine remains relatively constant in wetland systems. Based on this recommendation, the initial approach in this modeling effort will be to use chloride as tracer to evaluate the model transport subroutine. 3. Period of Record Some of the processes and transformations that occur in wetland systems sometimes take years. An example of a long term process is the shift in plant community composition that may occur after the accumulation and/or release of phosphorus in the soil. These factors underline the need to perform long-term simulations. An ideal period-of-record (POR) covers a large number of years with periods of extreme meteorological and hydrological conditions that adequately calibrate and test the model performance. It is also of value to have a POR that includes major structural changes (e.g. diversion of S-6 pump, STA-1E operation) because this further tests the models ability to project such changes. It is desirable to select a POR ending as close as practical to the present. The POR for model calibration and possible verification should consider data availability, and quality. This task will require a preliminary review of data from various sources. Accordingly, a tentative POR is selected to be 1995 – 2004. This period will be further divided into two segments where one will be used for model calibration, and the other for validation. This report summarizes the types of data that have been collected for the POR, identifying any missing periods and indicating the apparent quality of such data. 4. Types of Data The field measurements needed to support this modeling effort include bathymetric, meteorological, hydrologic, and water quality data. Many of these datasets are spatially variable (e.g., elevation), and some are both temporally and spatially variable such as all meteorological, hydrologic, and water quality parameters. Data sources will be identified for all data types required. The types of data that have been compiled and are discussed in this report are: • Bathymetric data • Hydrologic data: water level and discharges through hydraulic structures • Meteorological data: rainfall, temperature, evapotranspiration (ET), and wind • Water quality data: concentrations of the parameters of interest at available sampling sites. 5. Procurement and Quality Assurance of Bathymetric Data 5.1 Marsh Elevation Data Bathymetric surveys for the Loxahatchee Refuge have been available from different sources and with different resolution. Lin and Gregg (1988) indicated that, in 1988, topographic maps of the Refuge were available from three different sources: (1) the U.S. Army Corps of Engineers (1958), (2) the Fish and Wildlife Service, Department of Interior (1963 and 1965), and (3) the South Florida Water Management District (1965). Lin and Gregg (1988) reported that, in some areas, there were considerable differences between the three sources. A later survey of the Refuge was conducted by Richardson et al. (1990) who collected topographic and vegetation cover data, as part of their study of refuge habitats and relationship to water quality, quantity and hydroperiod. The topographic data was collected at a resolution of approximately 1 minute (roughly 2 Km) by measuring the water depth at all grid locations and then subtracting from an assumed horizontal water level. A flat pool condition of water in the Refuge was obtained by holding water at the 17-foot level during the time that the grid survey was being conducted. The latest elevation data for the Refuge are available from the United State Geological Survey (USGS). The elevation data were collected as “bare earth” ground elevation on a 400 by 400 meter grid. "Bare earth" in the Everglades swamp environment is considered to be the layer of "muck" which supports a one-pound weight on a bearing surface of approximately 5.3 square inches or 2.6-inch circle. According to Desmond (2003) the horizontal positions were established by GPS observations and are referenced to the North American Datum of 1983 (NAD83). The horizontal accuracy is +/- 15 centimeters. Similarly, the elevation data have a vertical accuracy specification of +/-15 centimeters (cm) relative to the North American Vertical Datum of 1988 (NAVD88). Desmond (2003) indicated that the vertical accuracy of the elevation data was determined based on the requirements for use as input to hydrologic models. More information about this elevation data is available at the USGS’s South Florida Information Access (SOFIA) website (http://sofia.usgs.gov/projects/elev_data/). Since the water level data from the Refuge interior stations and from the water management structures are based on the National Geodetic Vertical Datum (NGVD29), the USGS’s bathymetric data were converted from the NAVD88 to the NGVD29 system using the National Geodetic Survey software “VERTCON” Version 2.1. Figure 1 shows the bathymetric contours for the Loxahatchee Refuge based on the USGS’s data. Results of this survey indicate that, in the Refuge, the bathymetry contours (excluding the rim channel) range from 18.50 to 10.61 ft (5.64 to 3.23 m) NGVD29, with a mean elevation of about 15.17 ft (4.62 m) NGVD29. Figure 1. Loxahatchee Refuge 2003 USGS Bathymetric Data As can be observed in the profile presented in Figure 2, the Refuge has a very mild north to south slope, which results in a generally slow southward flow movement. Lin (1979) indicated that flow through the heavily vegetated area in the Refuge is extremely slow as compared to the flow in canals. The north to south slope is estimated to be about 1.6 cm in 1 Km (1.0 inches per mile). In the west to east direction (see Figure 3), the terrain is undulated showing mounds and depressions, but with basically an average horizontal slope. 10 11 12 13 14 15 16 17 18 Ground Elevation (ft NGVD29) Average Slope = 0.085 ft/mile Overland Surface 0 2 4 6 8 1012141618202224 Distance from Point A (miles) Figure 2.

West to East Ground Profile of the Loxahatchee Refuge 5.2 Rim Canal Cross-Section Data The rim canal bathymetric data were collected by the University of Florida’s Institute of Food and Agricultural Sciences (IFAS), specifically by the Everglades Research and Education Center. This survey of the rim canal was performed in 2001 by Daroub et al. (2002) as part of the project: Implementation and Verification of Best Management Practices for Reducing Loading in the Everglades Agricultural Area (EAA). The survey was conducted by measuring sediment depth and channel bottom depth with reference to the transect’s surface water level at the time of the measurement. The water depths were later converted to elevations using the mean tail-water elevation of station G-310 (referenced to NGVD29) that prevailed on the day of measurement. It was assumed that there was no hydraulic gradient between G-310 and the transects at the time of measurement. Sediment samples and cross section elevations were taken approximately at one-mile resolution. The transect locations of the survey are shown in Figure 4. Figure 4. Rim Canal Transects (IFAS Survey) Twenty eight transects were taken for each canal system, i.e., the western system that is formed by the L-7 and L-39 canals and the eastern system that is formed by the L-40 canal. The distance between transects ranges between 1.15 and 0.90 miles for the western system and between 1.03 and 0.92 miles for the L-40 canal, being the average distance equal to 1.0 mile for both systems. As indicated before, sediment surface levels and channel bottom levels were measured, and were standardized with the G-310 tailwater elevation as reference level. The G-310 tail-water level is based on the National Geodetic Vertical Datum (NGVD29). Figure 5 shows the cross section elevations for the L40-01 transect.

Cross Section for the L40-01 transect, indicating channel bottom and sediment surface elevation (Reproduced after Daroub et al., 2005). For the western canals, the sediment surface elevations range between 7.0 and -1.5 ft NGVD29 with a mean elevation equal to 2.4 ft. For the L-40 canal, the sediment surface elevations range between 6.7 and -5.7 ft NGVD29 with a mean elevation equal to 3.2 ft. The top width ranges between 205 and 120 ft for the western canal, and between 173 and 88 ft for the L-40 canal, the mean top widths are 169.7 and 121.5 ft for the western and for the L-40 canals, respectively.

The profiles for the L/7/L-39 canals are quite irregular with almost a horizontal average slope. Channel aggradation seems to have occurred in the L-7 canal as results of an adverse slope in the channel bed; for this canal the sediment depths vary between 10.2 and 2.5 ft with an average depth of approximately 5.5 ft. It is important to note two other major features in these profiles: a thalweg drop of more than 4 ft between canal miles 15 and 16, close to the confluence of the L-7 and L-39 canals; and a steep adverse slope with great accumulation of sediments between canal miles 21 and 23 in the L-39 canal. On the other hand, the profile for the L-40 canal is better defined with a north to south mild slope of about 3.2 inches per mile, see Figure 7. The sediment depths for the L-40 canal range between 6.6 and 0.9 ft with and average depth equal to 3.0 ft. Another interesting observation to the canal data is the difference of more than 8 ft on sediment elevations for the downstream ends of L-39 and L-40 canals, when these points are only about 1.7 miles apart.

Procurement and Quality Assurance of Water Level Data 6.1 Interior Station Stages The water levels in the Loxahatchee Refuge change due to drought, rainfall, evapotranspiration, seepage, and surface water management based on regulation schedules that vary with the time of the year, hydrologic, and other needs (SFWMD, 2005). According to the USFWS (2000) the purpose of these schedules is to regulate the water level in WCA-1 to produce maximum benefits for flood control, water supply, fish and wildlife, and prevention of salt water intrusion. A schematic diagram of the current water regulation schedule (established in May 2005) is shown in Figure 8. 18 17 16 15 14 13 12 Water Elevation (NGVD feet) ZONE A1 ZONE B Water releases, as needed, depending upon elevation at Lake Okeechobee Active ZONE A2 Water releases linked to amount of rainfall and elevation at Lake Okeechobee ZONE C No net water releases due to drought w ater releases, due to flood conditions JanuaryFebruaryMarch April MayJune JulyAugust SeptemberOctoberNovemberDecember Figure 8. Water Regulation Schedule for Water Conservation Area 1 (Reproduced after Comprehensive Conservation Plan for the Loxahatchee National Wildlife Refuge, USFWS, 2000) Spatial water level information inside the Refuge is scarce. Actually there are only five active stations inside the Refuge, two of them in operation just after mid 2001. These five stations are referred as 1-7, 1-9, 1-8T, North and South. The location of USGS’s water level monitoring stations is shown in Figure 9. Historic daily average water level data from 1954 to 2005 are available at USGS sites 1-7, 1-9, and 1-8C, although the site 1-8C is located in the rim canal. The stage-monitoring site 1-8T has water level measurements since 1979. Water level data from recently installed USGS sites North and South are available only after June, 2001. The water level data can be obtained at the SFWMD’s Environmental Data Base (DBHYDRO) website (www.sfwmd.gov/org/ema/dbhydro/). Table 3 shows the available and missing data for each of these stations for the POR. A more detailed description of the interior stage missing data is presented in Appendix G.1. Figure 9.

The DBHYDRO database usually presents more than one time series available for each gage. For the selected POR (1995 to 2004), there are between 3 and 5 different time series available for each of the sites 1-7, 1-8T, 1-8C and 1-9. Most of these time series data sets have overlapping time periods. There is no explanation at the website about this issue, however, the DBHYDRO browser user documentation manual recommends that “whenever "PREF" data are available for a date record of interest it should be used to exclusion of all other data” since “such data sets already underwent a second level of quality assurance and quality control (QA/QC) by engineers in Environmental Monitoring and Assessment Division” (SFWMD, 2003). Since not all the stations include a “PREF” file or the “PREF” file does not always cover the complete period of interest, all the time series available were retrieved from the DBHYDRO website and compared against each other. Appendix A1, Figures A1.1 to A1.22, shows the time series available for each gage and also the comparisons between them. Table 4 shows the names of the time series available for each gage, and also the time series that were selected to be used during the Refuge modeling effort. This table also indicates the arithmetic means of daily average water levels for the POR, and the maximum and minimum daily average stages reported during such period. The major observations to the time series, as well as any modification to the data, are also reported in Table 4. For the POR, the arithmetic means of daily average water levels for the interior stations (1-7, 1-8T, and 1-9) range between 16.55 and 16.26 ft NGVD29, and the maximum and minimum daily average stages are 18.12 and 13.94 ft NGVD29, respectively. For gage 18C (located in the rim canal) the arithmetic mean of daily average water level is 16.31 ft NGVD29, and the maximum and minimum daily average stages are 18.19 and 12.06 ft NGVD29, respectively. Gage North presents a higher average stage (16.73 ft NGVD29) than the rest of the stations, and gages South has a lower average stage (16.10 ft NGVD29), but these stations only have data for the period from May 2001 to December 2004.

These data are essential for documenting the spatial and temporal stage variations along the rim canal. The water level data for the hydraulic structures were divided into four groups according to the structure location: a) the northern stations, this group includes structures S-5A, S-5AS, G-301 and G-300; b) the western stations, this group includes structures G-310, G-251, S-6, S-10E and G-338; c) the southern stations, structures S-10D, S-10C, S-10A and S-39 are included in this group; and d) the eastern stations, structures S-362, ACME-1, ACME-2 or G-94D, G-94C, G-94B and G-94A are included in this group. Figure 10 shows the location of the hydraulic structures associated with the Refuge. Figure 10. Location of Hydraulic Structures in the Loxahatchee Refuge Table 5 shows the available head- and tail-water level data for the nineteen hydraulic structures around the Refuge. As can be observed in the table, not all the structures were in operation from the start date of the POR. For example, structures G-301 and G-300 started operating in August 1999 (Waldon, 2005). Structure G-310 started operating on July 2000 (Waldon, 2005). On the other hand, the structures located at the eastern part of the Refuge (ACME-1, G-94D, G-94C, G-94B and G-94A) were in operation for the complete POR. For these stations, the time series available at the DBHYDRO website are missing between 57 and 89 months with respect to their head and tail water levels, while some stations do not have head water levels available (see Table 5). The investigators are continuing to search for the missing data. Head and Tail water level data for the stations S-10D, S-10C and S10-A is also available at the USGS website (http://water.usgs.gov/data.html). A more detailed description of the head and tail water level missing data is presented in Appendix G.2. Table 5.

The time series available for each station, as well as the comparison among them, are included in Appendix A2, Figures A2.1 to A2.66. Data for the S-362 station is only available after 10/14/2004, and therefore the head and tail water levels time series for this station were not included in the appendices. Tables 6 to 9 summarize the major observations to the head and tail water level data, and also indicate the time series recommended to be used for the modeling effort. If not otherwise indicated, the data in the time series shown in Tables 6 to 9 and Appendix A2 are daily mean values. As seen in Tables 6 to 9, the arithmetic means of daily average water levels inside the Refuge range from 16.28 to 15.93 ft NGVD29 for the 17 hydraulic structures, and for the POR. Similarly, the maximum and minimum daily average stages are 18.98 and 11.54 ft NGVD29, respectively. It is observed that for the POR the water level for the structures along the rim canal, on average, is lower than that of the interior stations. However, the maximum daily average stage reported for the structures (i.e., 18.98 ft) is higher than the maximum value reported for the interior stations (i.e., 18.12 ft). This information shows that, on average, the water level in the channel is lower than the water level of the marsh. However, under certain conditions the water may overflow the rim canal and moves as sheet flow toward the interior of the Refuge. According to Waldon (2005) at high stages there is typically little difference between stage in the marsh and at non-operating structures and pumps. When outflow gates are opened, stages at the structure headwaters fall below the stage representative of the broader region of the canal in the vicinity of the structure. At lowest canal stage, water surface elevation falls below interior marsh soil elevation and monitored marsh stages. Note in Tables 4 to 9 and for the rest of this document, the term “extreme event” has been used arbitrarily to indicate a period of time when a particular parameter, e.g., water level, shows an unusual high or low value when compared to other high/low values and/or to the arithmetic or geometric mean of the data. The classification of a period of time as an “extreme event” is partially subjective, and has no other purpose than to illustrate such particularity of the data. Table 6.

Procurement and Quality Assurance of Flow Data The nineteen hydraulic structures associated with the water management of the Refuge are shown in Figure 10. In the previous section, these structures were classified according to their geographical location. They can also be classified according to the direction of the flow as: a) inflow structures: S-5A, G-310, G-251, S-6, S-362, ACME -1 and ACME -2 (ACME-2 is also referred as G-94D); b) outflow structures: S-10E, S-10D, S-10C, S10A, S-39, G-94A, and G-94B; and c) bidirectional flow structures: S-5AS, G-301, G300, G-338 and G-94C. Discharge Data are available for the 19 structures from the DBHYDRO website (additional data for the S-362 station was obtained from SFWMD’s personal). However, the data for some of the stations do not cover the complete period of record, namely from January 1995 to December 2004 (see Table 10). A more detailed description of the flow missing data is presented in Appendix G.3. Table 10.

However, these stations were diverted away from the Refuge at some points during this period. The S-5A pump station discharged into the Refuge until August 1999, when it was diverted to the western stormwater treatment area (STA-1W). Similarly, structure S-5AS and the S-6 pump were diverted away from the Refuge in June 1999 and May 2001, respectively. The diversion of the S-6 pump represented a major removal of water and phosphorus loading from the Refuge (Waldon 2005). On the other hand, structures G-301 and G-300 started operating in August 1999. These structures are bidirectional and allow occasional discharge of water from the West Palm Beach Canal directly into the Refuge, and also release of water at the north end of the Refuge to the C51 Canal. The water from the West Palm Beach Canal is normally discharge to STA-1W, and the effluent water from STA-1W is later discharged into the Refuge, approximately 10.6 Km south of G-301 structure, through the large pumping station G-310 (3,040 cfs capacity), and a much smaller pumping station G-251 (Waldon 2005). Structure G-310 started operating in May 1999. On the other hand, structures G-94A, G-94B and G-94C have been in operation during the complete POR. According to Waldon (2005) these structures are primarily for agricultural and urban water supply; they intermittently discharge relatively small volumes out of the Refuge during the dry season. The time series available from the DBHYDRO website for these stations are missing approximately 63 months of discharge data for each of the sites. For the selected POR (1995 to 2004), The DBHYDRO database presents between 2 and 6 different time series available for each hydraulic structure, with the only exception of stations G-338 and S-362 that have only one time series available. As mentioned earlier, the DBHYDRO browser user documentation manual recommends the utilization of the data identified with the “PREF” recorder, since these time series already underwent a second level of QA/QC by SFWMD personnel. However, since not all the stations include a “PREF” file or the “PREF” file does not always cover the complete period of interest, all the time series available were retrieved from the DBHYDRO website and analyzed. Appendix B shows the discharge time series available for the hydraulic structures, as well as the comparisons among them (see Figures B.1 to B.84). Each of the available time series was reviewed, looking for outliers and discrepancies in the data. Tables 11 to 14 indicate the time series available for each site, summarize the major observations to the data, and indicate the time series that are recommended for future use during the Refuge modeling effort. The arithmetic mean of daily average, and the maximum and minimum daily average discharges were calculated for each structure, and are also reported in Tables 11 to 14. These tables also report the major periods of consecutive operational days, i.e., days of non-zero flow (this is referred as “flowing period”) and the major periods of zero-flow (this is referred as “non-flowing period”), and the modifications to the selected time series after the completion of the quality assurance checks. Based on the POR and according to the management structures’ operation, pumping stations G-310, S-6 and S-5A present the highest arithmetic mean of daily average inflows, with a flow close to 400 cfs. The maximum recorded daily average discharge is equal to 4,779 cfs through pumping station S-5A. Meanwhile, stations G-310 and S-6 show maximum daily average discharges equal to 3,224 and 2,920 cfs, respectively. Structures S-39 and S-10D present the highest arithmetic mean of daily average outflows to the Refuge with a flow close to 180 cfs. Structures S-10C and S-10A have an arithmetic mean of daily average discharge (outflow) close to 145 cfs. The maximum recorded daily average outflow from the Refuge is 4,921 cfs through spillway S-10A. Table 11.

For the POR, the yearly average inflow to the Refuge is 579,038 acre-ft and the yearly average outflow is 576,141 acre-ft. For this long-term cumulative the total outflow is only 0.5% lower than the total inflow. The close balance between inflows and outflows through the water control structures, and the fact that the annual average rainfall and potential evapotranspiration (ETp) are similar (Abtew et al. 2005), indicates that water losses through seepage may not be significant in the long-term average scenario. The average annual rainfall in the entire region managed by the SFWMD is 52.8 inches, while the average ETp is reported to be 52.6 inches (Waldon 2005). Table 15.

Procurement and Quality Assurance of Meteorological Data 8.1 Rainfall Data Daily rainfall data are available at different locations inside and close to the Loxahatchee Refuge. There are five stations inside the Refuge: 5A, S-6, S-39, WCA1ME, LOXWS and one station located at the Everglades Nutrients Removal Project (ENRP) site, which is located adjacent to the northwestern boundary of the Refuge. These six rainfall measurements stations are operated by the SFWMD and Data are available from the DBHYDRO website. There are also ten additional rain gages located adjacent to the Refuge. Data for these stations were provided by USFWS’s personnel. The location of the rainfall measurements stations is shown in Figure 11. Stations S-5A, S-6, and S-39 have daily average rainfall measurements since 1956, 1960 and 1963, respectively. The weather station WCA1ME has rainfall measurements since 1994, and weather stations LOXWS and ENRP have measurements since 1996. The aforementioned ten additional rain gages are located adjacent to the Refuge in Basin A and Basin B. Location of rain gages in Basin B (Gage 6 through Gage 10) is shown in Figure 11. Daily rainfall measurements from these gages are available since January 1997. Gage10 (PS-2) was added to this rain gage network in April 2000, and its daily rainfall Data are available since then. Historical rainfall measurements at USGS water level monitoring sites 1-7, 1-8C, and 1-9 are also available at the DBHYDRO website. However, these rain gages are not currently in operation. Daily average rainfall data from these gages are available only for the period of 1960 to 1984. Availability of rainfall data for the POR (1995-2004) is shown in Table 16. This table also includes the information about missing data along with start and end dates of available periods. A more detailed description of the rainfall missing data is presented in Appendix G.4. Daily rainfall measurements from all these rain gages are plotted and presented in Appendix C. There are more than one time series of rainfall data available from stations S-39, S-5A, and S-6. Rainfall stations S-5A and S-6 have “PREF” time series files that will be used to estimate rain at those stations. Rainfall station S-39 has three time series files (6035, 16677, and K8674) that do not have a good agreement with each other. Time series 6035 and K8674 have better match with each other than with the time series file 16677. Thus, the time series files 6035 and K8674 will be used to estimate rainfall at S39 station. Plots showing comparison of rainfall records for different time series are also presented in Appendix C. Figure 11. Location of Rain Gages and Weather Stations Table 16.

This table indicates that the average annual rainfall records from new gages (Gage 1 to Gage 9 in the table) are higher than the average annual rainfall from SFWMD’s rain gages. Years with more than 30 days of missing data were not included in the calculation of the annual average rainfall. For years with less than 30 days missing, the total sum of rainfall was compared with nearby gages with complete data. If the total cumulative rainfall for the year with missing data was smaller than the nearby gages, then a decision was made to discard such a year from the calculation of the annual average of rainfall. An exception was made with the 1999 data for the LOXWS gage. For this year the gage has 48 days missing, but the total rainfall sum was higher than nearby gages and also the highest individual year value for the gage, and therefore it was included in the calculation without filling any missing day. In summary, annual average rainfall recorded from these new gages from the year 1997 to 2004 is 64.56 inches, whereas, average rainfall recorded from SFWMD’s rain gages for the same period is 49.18 inches. The difference in annual rainfall measurements from these two different sources is about 15 inches, which is considerable. Such a large discrepancy must be addressed before the modeling efforts commence. Effort is underway to obtain RADAR rainfall estimates from the SFWMD. These estimates will be compared to the point gauge estimates and possibly used in the modeling effort. More discussion on this issue will be provided in subsequent reports. In terms of seasonality, more rainfall seems to be occurring during the months June- October compared to the rest of the year. Maximum daily rainfall over the refuge was recorded on October 15, 1999. On that day, most rain gages recorded about 8 inches of rainfall, whereas stations S-39 and S-5A recorded less than 2 inches of rain. Table 17. Summary of Available Rainfall Data.

Also, pan evaporation and potential evapotranspiration are available from stations S-5A and LOXWS, respectively. The location of these stations is shown in Figure 11, and the availability of data is summarized in Table 18. A more detailed description of the evaporation and ET missing data is presented in Appendix G.5. Time series of evaporation and ET measurements are included in Appendix D. A comparison between ET measurements from STA-1W and potential ET from weather station LOXWS is also included in this Appendix. This comparison shows that, in general, potential ET estimated from LOXWS is less than ET measurements from STA-1W. Figure 12 shows the ET’s seasonal variation estimated from STA-1W for the POR. As can be observed in this figure, ET is higher during the months of March to August (with values higher than 4.5 inches), reaching a peak of about 6 inches in May. A regional evaluation of ET in the everglades conducted by German (2000) presented similar results to those shown in Figure 12. Annually, the average ET from the STA-1W station for the POR is equal to 52 inches, which is almost equal to the annual average rainfall from SFWMD’s rain gages. Table 18.

Seasonal Variation of ET Estimated at STA1W 8.3 Air Temperature Data Air temperature data for the Refuge are available from weather station LOXWS (see Figure 11). The available data covers the complete POR; however, there are 320 days of missing data from which 85 days are continuous. A detailed description of the air temperature missing data is presented in Appendix G.6. It should be noted that there were five days with temperature equal to 0ºC that were converted to missing data. Figure 13 shows the temperature time series from station LOXWS including the missing and zero- temperature days. Excluding the five days with temperature equal to 0ºC, the daily temperatures range between 7°C to 30°C, with an annual average of 23.4 °C for the POR. Figure 14 shows the seasonal variation of air temperature observed at LOXWS for the POR. As can be observed in this figure, air temperature is higher during the months of May to October (with values close or higher than 25°C), reaching a peak of about 27.3°C in August. For the POR, the monthly average temperature ranges from 17.8°C to 27.3°C. 0 5 10 15 20 25 30 35 1/1/95 2/5/96 3/11/97 6/23/00 7/28/01 9/1/02 10/6/03 11/9/04 Temperature (degrees) Air Temperature Measurements from Weather Station L0XWS 4/15/98 5/20/99 Figure 13.

For these sites, wind speed data are available for the complete POR, but there is not information about wind direction. The ENR308 site is a weather station located at the Everglades Nutrients Removal Project (ENRP), which is located adjacent to the northwestern boundary of the Refuge. Station S-5A also has wind speed measurements, but it covers only until August 1998, and wind direction data are also not available. Wind speed and wind direction data are available at three USGS stations located close to the Refuge, but data for two of these stations are only available for 1996 and 1997. The other USGS station has data for the period of January 1996 to September 1999. There is a fourth USGS station close to the Refuge, but the wind data are missing. More information about the USGS stations is presented in German (2000). Additional to the data of the aforementioned stations, wind direction along with wind speed data were obtained from the National Climatic Data Center (NCDC). The Local Climatological Data for the NCDC are collected at the West Palm Beach International Airport (PBI). The location of the wind stations is shown in Figure 15, and Table 19 summarizes the availability of wind data. Table 19.

Plots of the available wind speed and wind direction dara are presented in Appendix E. For the POR, the average wind speed for stations ENR308 and LOXWS are 6.97 and 6.59 mile/hour, respectively. The maximum recorded daily average wind speed for these stations are 36.87 and 38.59 mile/hour respectively. The maximum wind speed at ENR308 was recorded on September 4, 2004, where the maximum wind speed at LOXWS was observed on March 01, 2001. Average S-5A wind speed from 1995 to 1998 is 4.67 mile/hour, which is lower than wind speed from the other weather stations. The average wind speed for the USGS stations 1, 3 and 4 (see Figure 15) are 3.78, 4.67 and 4.68 mile/hour, respectively. Figure 15. Location of Wind Stations 9. Procurement and Quality Assurance of Water Quality Data 9.1 Water Quality Data Water quality data for the Loxahatchee Refuge are available from five different sources: 1) the Everglades Protection Area (EVPA) water quality monitoring sites, 2) the “Enhanced” water quality monitoring sites, 3) the District Transect monitoring sites or XYZ data, 4) the water quality monitoring sites located at the hydraulic structures, and 5) additional independent monitoring sites. Water quality data for groups 1, 2, 4 and 5 can be downloaded from the SFWMD’s DBHYDRO database, and the XYZ data can be requested from the SFWMD. There are fourteen Everglades Protection Area (EVPA) water quality monitoring sites inside the Refuge marsh that were active during the period of study. These water quality stations were designed to monitor the physical, chemical and biological quality of the Refuge. Table 20 shows some of the water quality parameters that are measured in the EVPA stations, and Figure 16 shows the location of these monitoring sites. Most of the water quality variables are sampled and reported monthly; however, not all the parameters are measured at the same frequency. The sampling frequency of water quality monitoring stations is irregular. The current SFWMD monitoring programs are described by Germain (1998). According to Weaver and Payne (2004) the sampling frequency in the SFWMD monitoring stations varies by site depending on site classification, variable group, and hydrologic conditions. More than ten years of water quality data can be retrieved from the SFWMD’s DBHYDRO database. It should be noted that water quality data at inflow and outflow control structures are typically sampled biweekly when flowing and monthly otherwise. Table 20.

TPO4 and TDPO4, for example, are respectively total phosphorus and total dissolved phosphorus as mg/L of phosphorus (not simply phosphate and not as phosphate mass). Figure 16. Location of Water Quality Monitoring Sites Inside the Refuge. 9.2 Total Phosphorus Data – EVPA Stations Based on the selected POR, total phosphorus (TP), and chloride (Cl) were retrieved from the DBHYDRO database for the 14 EVPA monitoring sites, i.e., stations LOX3 to LOX16. Figure 17 shows the location of the EVPA stations. The TP time series for each station are included in Appendix F1. For the POR, the sample size (number of data points available) varies between 65 and 122, the arithmetic averages of measured TP concentrations vary between 7.3 and 11.8 mg/L, and the geometric means between 6.6 and 10.1 mg/L. The TP mean concentration for all the EVPA sites together is between 9.2 and 9.0 mg/L (the uncertainty in this estimate is due to several values that were reported to be less than the limit-of-detection). Table 21 indicates, for each EVPA site, the arithmetic average, the geometric mean, the maximum and the minimum reported value, the sample size, and the start and end dates of the available data (all this information is according to the selected POR). This table also summarizes the major observations to the data and the modifications it underwent after the quality assurance checks. Figure 17.

However, data for these stations are only available after June 2004, and the number of data points available for TP varies between just 4 and 7. The location of the “Enhanced” monitoring sites is shown in Figure 18. The arithmetic averages for the enhanced sites range from 7.8 to 188.4 mg/L, and the geometric means from 7.4 to 138 mg/L. The TP mean concentration for all the enhanced sites together is 49.9 mg/L. The high values of the means and their wide ranges are related to the fact that some of the sites are located close to the rim canal, and are affected by the penetration of canal water into the marsh. Table 22 shows a summary of the TP data for the enhanced sites, and also the major observations and modifications to these data. Figure 18.

The location of the “XYZ” stations is shown in Figure 19, and the TP time series for each station are included in Appendix F2. According to the SFWMD (2000) these stations were established along a nutrient gradient in the southwestern corner of the Refuge (see Figure 19) for biological and chemical sampling. Data for these stations are available from April 1996. The sample size for these sites varies between 107 and 142 values per site, for the POR. Arithmetic means of TP concentrations during the period of record range between 9.0 and 56.5 mg/L, and the geometric means vary between 8.1 and 49.9 mg/L. The highest concentration values correspond to canal water, and it declines as the distance from the rim canal increases. Figure 20 and 21 shows the variation in the TP arithmetic and geometric means, respectively, with respect to the distance from the rim canal. In both cases, the TP concentration steadily decreases as the distance from the canal increases until about 1.5 Km, where the TP values become almost constant at about 10 mg/L and independent of the distance from the canal. Figure 19. Location of the “XYZ” Water Quality Monitoring Sites Table 23 shows a summary of the TP data for the “XYZ” sites, and also the major observation and modifications to these data.

Water quality Data are available from 15 of these sites (for the complete POR); only the structures G-251, G-338, S-362 and G94A (see Figure 10) do not have data available, and structure G-94C presents data for only three single days. The data for the G-251 have been requested to the SFWMD. Stations S-5A, G-310 and S-6 have grab samples and composite samples. The rest of the stations have only grab samples. For the data that was gathered as “grab sample”, and excluding station G-94C, the sample size for the period of record ranges between 81 and 534 samples per site, with a mean equal to 177 samples per station. The TP time series for these stations are included in Appendix F3. The TP arithmetic means vary between 35.2 and127.4 mg/L, and the geometric means vary between 30.7 and 113.1 mg/L (excluding station G-94C). The arithmetic mean for all these sites together is equal to 80.9 mg/L. Table 24A summarizes the information regarding “grab” TP measurements at these stations, and indicates the major observations and modifications to the data after the quality assurance checks. The composite data are for a 7-days period, and the date reported is the last day of the composite. The samples were composite either by time or by flow. Table 24B summarizes the information about the composite TP measurements at stations S-5A, G-310 and S-6. For the data gathered as “composite sample” the sample size for the POR ranges between 160 and 314 samples per site. The TP arithmetic means vary between 55.2 and 141.5 mg/L, and the geometric means vary between 44.2 and 124.0 mg/L. The TP time series for these stations are also included in Appendix F3 9.6 Total Phosphorus Data – Additional Stations Besides the data described in the previous sections, the DBHYDRO database includes data for other five stations associated with the Refuge. These stations are known as S5AD, S6D, L40-1, L40-2 and ACME1DS. Site S5AD and S-6D are downstream of the S-5A and S-6 pumping stations, respectively, and L40-1 and L40-2 are monitoring stations on the downstream side of ACME 1 and ACME 2. The site ACME1DS is located in the L-40 Canal. According to Waldon (2005) when the pump (ACME-1) is flowing this site may not be representative of the L-40 Canal because the sampling point is in the discharge from the gated culverts. For these additional stations, the sample size varies between 56 and 119 samples per site. The TP arithmetic means range between 57.8 and 117.5 mg/L, and the geometric means range between 51.9 and 101.8 mg/L. The arithmetic mean for the four sites together is equal to 86.0 mg/L. Table 25 summarizes the information regarding TP measurements at these stations, and indicates the major observations and modifications to the data after the quality assurance checks. The TP time series for these additional stations are included in Appendix F. Table 24A.

The sample size for Cl varies between 41 and 112 data points per site for the POR. The Cl arithmetic means range between 13.5 and 67.6 mg/L and the geometric means between 12.7 and 58.0 mg/L (see Table 26). The arithmetic mean for all the EVPA Cl measurements during the POR is equal to 31.8 mg/L. Table 26 indicates, for each EVPA site, the arithmetic average, the geometric mean, the maximum and the minimum reported value, the sample size, and the start and end dates of the available chloride data (all this information is according to the selected POR). This table also summarizes the major observations to the data and the modifications it underwent after the quality assurance checks. The time series for chloride are shown in Appendix F5. The relationship between TP and Cl arithmetic and geometry means can be observed in Figures 22 and 23, respectively. There is virtually no correlation between TP and Cl averages for the EVPA stations.

The number of data points available for Cl varies between just 3 and 7. All the CL samples at the “Enhanced” stations were collected as grab samples. The Cl arithmetic averages for the enhanced sites range from 16.9 and 114.0 mg/L, and the geometric means from 16.2 to 110.2 mg/L. The Cl mean concentration for all the enhanced sites together is 58.7 mg/L. As in the case of the total phosphorus, the high values of the means and their wide ranges are related to the fact that some of the sites are located close to the rim canal, and are affected by the penetration of canal water into the marsh. Table 27 shows a summary of the Cl data for the enhanced sites, and also the major observations and modifications to these data. Figure 24 and 25 show the relationship between the means of TP and Cl for the enhanced stations. These figures show that the TP means tend to increase as the Cl means increases, however a poor correlation is observed between the variables.

Chloride data for these stations are available from April 1996. For this period of record, the sample size varies between 103 and 121 data points per station. The Cl arithmetic means vary between 40.4 and 148.6 mg/L, and the geometric means range between 34.1 and 138.7 mg/L. The arithmetic mean of all the Cl measurements during the period of record is equal to 92.7 mg/L. As in the case of TP, the Cl concentration exhibits a gradient of decreasing concentrations as the distance from the rim canal increases (see Figures 26 and 27). However, as shown in Figure 26, the gradient for the TP is steeper and the concentrations decrease to a fairly constant value (about 10 mg/L) within the first 1.5 Km. The Cl concentration decreases less rapidly and it seems to drop to a relative constant- interior value (about 50 mg/L) within 3.2 Km of the rim canal. The relationship between TP and Cl means for these stations are shown in Figures 28 and 29. The data in these Figures can be grouped into two different sets: (a) the stations close to the canal (distance to the canal less than 0.6 Km) that show high values for both TP and Cl, and (b) the stations located in the interior zone (distance to the canal greater than 0.6 Km) that show a almost constant value for the TP (varying between 9.0 and 16.3 mg/L for the arithmetic averages) and a variable Cl concentration (varying between 40.4 and 105.5 mg/L for the arithmetic averages). This tendency is not surprising, since the Cl is a more conservative substance than TP. TP concentrations are affected by biological uptake and other biochemical processes in the marsh, while the Cl concentrations basically decline as the result of dilution (SFW*-/MD, 2001). Table 28 summarizes the information for the Cl data at the “XYZ” sites. This Table indicates the major observations to the data. The Cl time series for each site during the period of record are included in Appendix F6.

Structures G-300, G-301, G-251, G-94A, G-338 and S-362 do not have data available, and the site associated with structure G-94C only presents data for three days (between March and April 2001). However, Cl data for the G-300 and G-301 may be assumed to be equal to the S-5A because of its proximity. Data for the G-251 have been requested from the SFWMD. Excluding station G-94C, the Cl sample size for the period of record ranges between 81 and 218 samples per site, with a mean equal to 129 samples per station. The Cl time series for these stations are included in Appendix F7. The Cl arithmetic means vary between 49.7 and 148.7 mg/L, and the geometric means vary between 49.0 and 144.6 mg/L (excluding station G-94C). The arithmetic mean for all these sites together is equal to 113.2 mg/L. Table 29 summarizes the information regarding Cl measurements at these stations, and indicates the major observations and modifications to the data after the quality assurance checks. Figures 30 and 31 show the relationships between the TP and Cl arithmetic and geometry means, respectively. For these stations, both the TP and the Cl concentrations are considerably higher than that of the interior stations. However, there is no correlation between the long term average TP and Cl concentrations.

Conclusions and Recommendations The main goal of this report was to compile and summarize the availability of data to support the Refuge hydrodynamic and water quality modeling effort. TP was selected as the main water quality parameter to be modeled, and chloride was selected as conservative tracer to evaluate the model transport subroutine. Marsh elevations, rim canal cross-sections, water level, discharge, rainfall, temperature, evapotranspiration, wind, TP and Cl data were gathered and evaluated. Overall, it is concluded that the available data is sufficient to achieve most of the modeling goals. In other words, the available data is sufficient to develop the boundary conditions that will force the hydrodynamic and water quality modules of the model. Data is also available for calibration and validation of the numerical model. Additional specific conclusions regarding the available field data include: o Data describing the interaction between surface and ground water is generally unavailable. However, there are estimates and studies that approximate leakage rates through the rim levee, and the recharge to groundwater from the marsh interior. A more detailed discussion about the surface-ground water interaction and the approach to address this issue will be provided in companion reports. o Wind direction data is only available at the West Palm Beach International Airport (PBI) station for the POR. There are wind-direction data available at three local stations but for only limited time (two years). o Atmospheric deposition data have not been discussed at this time. These data are currently being collected and evaluated. Even though, there is a good amount of data on both wet and dry deposition in the Everglades, the available time series have significant gaps due to instrumental failures and sample contamination (Ahn, 1999). The initial approach in this modeling effort will be to use a constant “dry” deposition and a constant “wet” rain concentration, and to perform model sensitivity analyses to determine whether or not this approach is adequate. o It should be noted that there are no velocity measurements in the rim canal or in the interior marsh. Therefore, the transport module of the numerical model will be evaluated only through the ability to reproduce the spatial and temporal distribution of the conservative tracer. 11. References Ahn, H.
