Abstract:
STREAMS is a subset of the HYDRO themes. The STREAMS theme consists of linear features. The HYDRO themes contain the hydrographic and fish information for Oregon and Washington BLM. This includes data originally captured in the WODDB HYDRO theme and data derived from other sources such as the Oregon Base Data Project, for example the DLGs from the USGS and the CFFs from the USFS. This data is fundamental to meeting the Oregon Washington BLM information needs including those for project design, watershed analysis, and the next decadal planning effort.
Purpose: Resource management planning, project design, watershed analysis

Attribute Accuracy:

Attribute Accuracy Report:
Attribute/Land Ownership Disclaimer:::::::: In general, nodes on the streams layer are placed at stream confluences. In some instances changes in attributes such as Hyd Flow, Plan Flow, Field Verification Date and Fish Species result in the placement of nodes between confluences. Nodes may or may not be placed at ownership boundaries. When there is no node at an ownership boundary, attributes on BLM ""span into"" private, state, or other federal lands on that specific arc. This does not imply that a particular attribute has been ""field checked"" on private land. This may lead to misinterpretation as some attributes such as Field Verification Date indicate an ""on the ground"" verification. The BLM does not conduct stream surveys on non-BLM-administered lands. Placing a node at each ownership boundary would result in an overwhelming number of nodes and make the streams layer very cumbersome. The reach breaks based on ownership will be addressed after the stream routing has occurred and the data is captured in the ARIMS database.

(WODDB) Attributes checked against original mylar maps for accuracy. Known Problem:::::::: There are
numerous attributes which occur in this theme that are not defined. It is possible that these attributes are holdovers
from one of the source themes, or that they may have resulted from improperly entered fields in the original attribute
data.
(DLG) Attribute accuracy is estimated to be 98.5 percent. Attribute accuracy was tested by one or more of the following
methods::::::::
- manual comparison of the source with hard copy plots
- symbolized display of the digital line graph on an interactive computer graphic system
- selected attributes that could not be visually verified on plots or on screen, were interactively queried and
verified on screen
In addition, U.S. Geological Survey Production System (PROSYS) software tested the attributes against a master set of valid
attributes for the category; it also checked for selected valid attribute combinations, and for valid attributes relative
to topology and dimensionality. All attribute data conform to the attribute codes current as of the date of digitizing.

Attribute Accuracy Explanation:

Logical Consistency Report:
(WODDB) The lines were checked against original mylar maps for accuracy. (DLG) Topological requirements include:::::::: lines must begin and end at nodes, lines must connect to each other at nodes, lines do not extend through nodes, left and right areas are defined for each line element and are consistent throughout the file, and the lines representing the limits of the file (neatline) are free of gaps. The tests of logical consistency were performed by the USGS PROSYS program. The neatline was generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region were ignored and all data crossing these geographically straight lines were clipped at the neatline. Data within a specified tolerance of the neatline were snapped to the neatline. Neatline straightening aligned the digitized edges of the digital data with the generated neatline, that is, with the longitude/latitude lines in geographic coordinates. All internal areas were tested for closure using PROSYS. This theme was built with line topology.
Completeness Report:
This theme will eventually cover all fifth field watersheds containing BLM lands, and all other watersheds of interest to the BLM, in the state of Oregon.

Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report:
(WODDB) Digital data are estimated to have a horizontal positional error of less than or equal to 13.3 feet (1/30 of an inch) at 1::::::::12,000 scale. (DLG) For Digital Revision Status = Not revised:::::::: Horizontal positional accuracy is based upon the use of USGS source quadrangles which are compiled to meet National Map Accuracy Standards (NMAS). NMAS horizontal accuracy requires that at least 90 percent of points tested are within 0.02 inches of the true position. The digital data are estimated to contain a horizontal positional error of less than or equal to 0.003 inches standard error in the two component directions relative to the source quadrangle. Comparison to the graphic source is used as control to assess digital positional accuracy. Cartographic offsets may be present on the graphic source, due to scale and legibility constraints.
For Digital Revision Status = Limited Update:::::::: This file has undergone standard update digital revision. Accuracy of
these digital data meets at least the class 2 postional accuracy specification in the draft United States National
Cartographic Standards for Spatial Accuracy.
For Digital Revision Status = Standard Update:::::::: This file has undergone standard digital revision. Accuracy of these
digital data meets at least the class 2 postional accuracy specification in the draft United States National Cartographic Standards for Spatial Accuracy.

Vertical Positional Accuracy Report:
(WODDB) Not applicable (DLG) For Digital Revision Status = Not revised:::::::: Vertical positional accuracy is based upon the use of USGS source
quadrangles which are compiled to meet NMAS. NMAS vertical accuracy requires that at least 90 percent of well-defined
points tested be within one half contour interval of the correct value. Comparison to the graphic source is use as
control to assess digital positional accuracy.
For Digital Revision Status = Limited Update or Standard Update:::::::: This file has undergone digital revision. Accuracy
of these digital data meets the class 1 positional accuracy specifications in the draft United States National
Cartographic Standards for Spatial Accuracy.

(DLG) For Digital Revision Status - Not digitally revised:::::::: This Digital Line Graph was digitized from the USGS source quadrangle, by either the National Mapping Division, one of
their cooperators, or one of their contractors. The digital data were produced by one of the following methods::::::::
- scanning a stable-based copy of the graphic materials. The scanning process captured the digital data at a
scanning resolution of at least 0.001 inches; the resulting raster data were vectorized and then attributed on
an interactive editing station.
- scanning the paper map. The scanning process captured the digital data at a scanning resolution of at least
0.001 inches; the resulting raster data were vectorized and then attributed on an interactive editing station.
- scanning a stable-based copy of the graphic materials. The resulting raster data were then manually digitized
and attributed on an interactive editing station. The resolution of the digital data is at least 0.001 inches.
- scanning the paper map. The resulting raster data were then manually digitized and attributed on an
interactive editing station. The resolution of the digital data is at least 0.001 inches.
- manually digitizing from a stable-based copy of the graphic material using a digitizing table to capture the
digital
data at a resolution of at least 0.001 inches; attribution was performed either as the data were digitized, or
on
an interactive edit station after the digitizing was completed.
- manually digitizing from the paper map using a digitizing table to capture the digital data at a resolution of
at
least 0.001 inches; attribution was performed either as the data were digitized, or on an interactive edit
station
after the digitizing was completed.
The determination of the DLG production method was based on various criteria, including feature density, feature
symbology, and availability of production systems. Four control points corresponding to the four corners of the
quadrangle were used for registration during data collection. An eight parameter projective transformation was performed
on the coordinates used in the data collection and editing systems to register the digital data to the internal
coordinates used in PROSYS, and a four parameter linear transformation was performed from the PROSYS internal coordinates
to Universal Transverse Mercator (UTM) grid coordinates. The DLG data were checked for position by one or more of the
following processes::::::::
- comparing plots of the digital data to the graphic source.
- comparing the digital data to the digital raster scan.
DLG data classification was checked by at least one of the following processes.
- comparing plots of the digital data to the graphic source
- comparing the digital data to the digital raster scan.

(DLG) A modified RevPG is run on the DLG files. RevPG is modified for two purposes:::::::: the first is to put all DLG files into double precision, which is a standard requirement for all data in OR/WA BLM libraries, and the
second is to add tools that assist in the insertion process. RevPG first converts the DLG to Arc format. The attribute
files for the lines, nodes, and polygons are then joined to the coverage and the coverage is built for line, node, and
polygon (for all polygon coverages). Next, the major and minor codes are used to recalculate certain other attributes.
These attributes are TXT, CAT, REV, CON, PIC, DSC, FST, FCO, MCD. Three more attributes are redefined from current
attributes (MATT, PGITEM, TWNRNG). Also, all null attributes or attributes with no data have their major and minor codes
set to -99999.

DLG) All quads are edgematched with adjacent quads. During this edgematch process they are also matched to the quad boundary contained in the index coverage of the library. This process snaps them so all themes for a
certain quad will match in extent. The process of snapping these coverages creates a box around the extent of the
coverage and snaps that box (using a snap tolerance of 5 for all coverages except PL, which uses a snap tolerance of 10)
to the index coverage quad.

INSERTed into the library, but only after many attempts have been made to force the PUTTILE command to be accepted.

The HYD, XHY, and HY layers were extracted from the corporate libraries and processed in an AML to create the Streams layer. Among other things, this AML converted the attributes of each layer to the new standard and,
where necessary, changed the data type of certain features. Manual edits were performed, including edgematching and
merging separate coverages, removing the pseudonodes from the merge process, and closing gaps in data. After these edits
had been performed, more processing was done to standardize coverage attributes and produce the final coverages and linked
info files.

Attribute Domain Values:

Unrepresentable Domain:
2-character entry. The first character classifies flow in relation to the expression of flow at the ground surface (space):::::::: interrupted or continuous. The second classifies flow in terms of the seasonal behavior of a water body over time in terms of surface flow (duration). SPACE
C - Continuous. A channel that does not have interruptions in space. It can be perennial,intermittent, or
ephemeral.
I - Interrupted. A channel which contains:::::::: 1) perennial flow with intervening intermittent or ephemeral
segments,
or 2) intermittent flow with intervening ephemeral segments.
G - Groundwater. Reaches that represent subsurface flow.
DURATION
P - Perennial. Streams which essentially flow year round. Perennial streams are generally associated with a
stable water table in the localities through which they flow.
S - Intermittent or seasonal. One that flows only at certain times of the year when it receives water from springs or from some surface source such as melting snow in mountainous areas. During the dry season, the water table is usually below these channels.
E - Ephemeral. One that flows only in direct response to storm precipitation and whose channel is at all times
above the water table. If the stream is truly ephemeral (it doesn't meet the NWFP definition of intermittent
as detailed in the attribute PLANFLOW) then code HYDFLOW with an 'E' but code PLANFLOW with an 'X'.
U - Unclassified. Unclassified surface flow. This code is used in connection with the ""G"" Space Classification. It is not intended to be a designation for surface flow duration.

Several additional codes have been added to HYDFLOW. These are used in lieu of the codes described
above and are intended for use with ditches, canals and pipelines. Here, a distinction is made between
open ditches/canals and closed or underground conveyances (WTRBODYTYPE DC vs PP).
DL - ""LOSS"" ditches and canals. Ditches or canals that transport water from a contributing fifth field watershed to a receiving watershed.
DG - ""GAIN"" ditches and canals. Ditches or canals that receive water from an adjacent fifth field watershed.
DI - ""INTERNAL"" ditches and canals. Ditches or canals that transport water within a fifth field watershed but are not connected to the adjacent fifth field watershed.
PL - ""LOSS"" pipelines. Pipelines that transport water from a contributing fifth field watershed to a receiving watershed.
PG - ""GAIN"" pipelines. Pipelines that receive water from an adjacent fifth field watershed.
PI - ""INTERNAL"" pipelines. Pipelines that transport water within a fifth field watershed but are not connected to the adjacent fifth field watershed.

Attribute Domain Values:

Unrepresentable Domain:
Standard values include the following::::::::
ST - Stream. All natural channels of flowing water other than those which have been designated on USGS
quads as being a river. This code includes colloquial names such as gully, wash, and creek. These
include those channels that flow only intermittently or ephemerally or those that are interrupted.
RI - River. All natural channels of flowing water which have been named as a river on a USGS quadrangle. All
other natural flowing channels are considered to be streams.
DC - Ditch or Canal. A constructed open channel for transporting water from a source of supply to the
point of distribution. The distinction between ditch/canal and stream is the man-made construction.
PP - Pipelines and covered water conveyance structures. Included here whether above or below ground (pipes, siphons, penstocks). Only features that are connected to a stream or lake system should be included here.
SC - Side channel. These river features are usually associated with complex stream patterns found with
multiple-channel stream types. This is not a main channel delineation. These are additional channels
which are located adjacent to the main channel delineation and are not considered a tributary. These
channels are generally located in the higher-order streams, particularly where the USGS quads have
recorded persistent island situations.
ES - Bay, Estuary, or Ocean. This code should be used to mark the inland extent of tidal influence. (Estuaries
are tidally-influenced ecological systems where rivers meet the sea and fresh water mixes with salt
water.)
For DLG source data, USGS specifications state that the inland extent of the estuary is defined at the
place
where a double-line river or stream reaches a width of 1 nautical mile with no further constrictions, if
the
conformation of the land and water do not otherwise make the division obvious. Within the DLG data, a
closure line is also placed to separate the bay, estuary, or ocean from the double line river.
LA - Lake or Pond. A naturally occurring body of fresh or saline water which is completely surrounded by land.
This is a standing body (not flowing) of water and is treated as polygon data. At this time there is no
size
threshold, therefore lakes and ponds are considered under the same code.
WT - Wetland. Areas that are inundated or saturated by surface or ground water at a frequency and duration
sufficient to support, and which under normal circumstances do support, a prevalence of vegetation
typically adapted for life in saturated soil conditions. Wetlands are treated as polygon data.
IM - Impoundment. A water body created by a man-made structure, such as a dam, built to collect or store
water. Reservoirs, dugouts, catchments, and impoundments are all included under this category. This is a
standing body (not flowing) of water and is treated as polygon data.
IW - Impounded Wetland.
UN - Unclassified water body. This code is used to represent water bodies that have not been classified.
Some WODDB features will initially have this code. It should be replaced as soon as possible with the
appropriate water body type code.
