Why was the data set created?

Data collected in this project will provide baseline information about a major current barrier to sheetflow, I-75. The data are expected to support the research on the existing linkages among geologic, hydrologic, chemical, climatological, and biological processes that currently shape the Everglades and will provide insight into the predrainage Everglades. The baseline flow will contribute to the Southwest Florida Feasibility Study addressing the health of upland and aquatic ecosystems in the 4,300 square mile area.

   Literature review of historical USGS and other agency data

   Incorporate multi-agency/university and modeling contacts into a review of previous and/or current projects related to flow monitoring across I-75 bordering the Big Cypress Basin eastern boundary and SR 29 on the western perimeter of the Preserve. Collate this information together with available GIS coverages for development of a plan to coordinate future flow measurement team deployment for both boundaries of the study area.

   Date: 2006 (process 2 of 7)

   Discharge measurements

   Reconnaissance of each bridge, culvert and wildlife through-way for appropriate measurement locations and methods. This includes documentation of weed conditions affecting periodic flow shifting, water depth, and establishment of reference marks to do distance to water measurements for indications of significant east-west flow "short-circuting".

   Discharge at each bridge, culvert and wildlife throughway will be measured in one day. Stream-flow measurements will be accomplished by Price AA meter, flow rods, or acoustic doppler point and/or profiling velocity meters as conditions at the controls allow.

   As of the end of September, 2006 four synoptic discharge measurements have been accomplished in the I-75 corridor from the L-28 Interceptor Canal to SR 29 and SR 29 from I-75 south to USGS site 02291000 Barron River near Everglades, FL.

   Initial evaluation determined the need to move one culvert index site scheduled for August 31, 2006

   Date: 2007 (process 3 of 7)

   Placement of stage and index gages

   Three index-velocity gages have been installed inside culverts running under I-75 and an additioal one may be installed in WY 2007. These gages collected stage and velocity data every 15 minutes, Additional measurements have been made at these culverts for discharge verification.

   USGS station 0229100 Barron River is now on telemetry so conditions can be looked at to better determine when discharge measurements are to b emade.

   Data collection and feasibility of study continuation

   The development of a discharge relationship is directly related to the DOI Science plan by giving a continuous record of discharge into Big Cypress National Preserve. If a relationship can not be determined, specific recommendations will be prepared concerning the best methodology. In order to ensure the instrumentation is working well, data will be downloaded once a month as well performing a discharge measurement just at that particular culvert.

   Tying in bridge reference marks to existing benchmarks

   DOT benchmark placement close to the bridges will be researched. A team of personnel will then go and field-truth the placement of the benchmarks to assess the feasibility of running a set of optical levels from the benchmark to a predetermined reference mark on the bridge. These bridge reference marks will be fully documented and the information will be provided to Big Cypress personnel.

   Reference marks that are tied into existing benchmarks will lead to water level measurements at specific bridges that are tied to the same datum plane.

   Date: 2007 (process 6 of 7)

   The index-velocity meters are operating and discharge measurements are being made to develop the index-velocity to discharge relationship. Evaluation of the discharge measurements made has shown the need for fewer measurements during the dry periods. This has resulted in clustering more of the measurements during the summer months than making measurements on a strict quarterly basis.

   Date: Not complete (process 7 of 7)

   Placemment of existing and future gages behind the I-75 fence to address safety concerns.

   This task is to work with the Florida DOT and their respective contractors to put gates in the existing fences sothat the equipment that is currently located in the median of i_75 can be moved inside the fence. This will allow the potential to telemeter thses sites in teh future so conditions can be easily monitored.
