 303d Lakes (2008)
The 303(d) Listed Impaired Waters program system provides impaired water data and impaired water features reflecting river segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act. Each State will establish Total Maximum Daily Loads (TMDLs) for these waters. Note the CWA Section 303(d) list of impaired waters does not represent waters that are impaired but have an EPA-approved TMDL established, impaired waters for which other pollution control mechanisms are in place and expected to attain water quality standards, or waters impaired as a result of pollution and is not caused by a pollutant; therefore, the "Impaired Waters" layers do not represent all impaired waters reported in a state's Integrated Report, but only the waters comprised of a state's approved 303(d) list. For more information regarding impaired waters refer to EPA's Integrated Reporting Guidance at: http://www.epa.gov/owow/tmdl/guidance.html 303(d) Waterbodies are coded onto NHD linear and area features to create Linear, Polygonal and Point Events. Point events represent impaired waterbody segments that do not fall on an NHD reach. 303(d) Waterbodies are coded onto NHD Waterbody reaches (region.rch) to create datasets. In addition to NHD reach indexed data there may also be custom event data (point, line, or polygon) that are not associated with NHD and are in an EPA standard format that is compatible with EPA's Reach Address Database. These custom features are used to represent locations of 303(d) waterbodies that are not represented well in NHD.

 Basin Boundaries HUC4 (2003)
The Geographic Information Retrieval and Analysis System (GIRAS) was developed in the mid 70s to put into digital form a number of data layers which were of interest to the USGS. One of these data layers was the Hydrologic Units. The map is based on the Hydrologic Unit Maps published by the U.S. Geological Survey Office of Water Data Coordination, together with the list descriptions and name of region, subregion, accounting units, and cataloging unit. The hydrologic units are encoded with an eight- digit number that indicates the hydrologic region (first two digits), hydrologic subregion (second two digits), accounting unit (third two digits), and cataloging unit (fourth two digits).

This data set contains a subset of the 109 Wyoming towns, cities, and census designated places (CDPs). This data set was originally created from U.S. Census Bureau Tiger Data. It contains many of the same attributes as the Census Bureau .dbf files, however there have been a few modifications. A code has been added to distinguish towns, cities, and CDPs. Also a Countyseat item has been added.

 Futures (2010)
This dataset contains the irrigated lands mapped for the Wind/Bighorn River Basin Plan. Irrigated lands were divided into the following categories: Irrigated Lands, Sub-irrigated Lands, and Water Awards. All previously unmapped areas were assigned to either Irrigated Lands or Sub-Irrigated Lands based on the visual interpretation of Digital Ortho Quarter Quadrangles (DOQQs) and 1999 Landsat color-infrared satellite imagery. Identified lands were then transposed onto USGS 1:24,000-scale, 7.5 Minute Quadrangle maps, attributed with water rights, digitized and placed into an ArcView 3.2a shapefile. Verification of irrigated versus sub-irrigated lands occurred during the assignment of water right attributes. Previously mapped lands - obtained from the Wyoming State Engineer's Office - were then incorporated into the irrigated lands shapefile and assigned to the appropriate category based on existing attributes. This dataset has been modified to show ONLY the Futures irrigated lands of the project. This was done to simplify the data for the client in the mxd.

 Instream Flows (2005)
The instream flow shapefile was created by georeferencing and digitizing the instream flow mylar maps to the PLSS and the wyorivers.shp file at a scale of 1:100,000, to give the user a better understanding of the instream flow segments in the State of Wyoming. The instream flows are descibed by their temporary filing numbers and permit numbers (if approved by the State Engineer), the priority date of the instream flow and the length of the instream flow segment in miles.

 Lakes (2004)
Hydrographic features for Wyoming at 1:100,000-scale, including perennial and intermittent designations and Strahler stream order attributes for streams. Does not include man-made ditches, canals and aqueducts. The data was originally produced by USGS, a Digital Line Graph (DLG) product, though this product was enhanced (edgematched, some linework and attributes corrected, stream order attribute added). A subset of this dataset is also available for distribution, including only major streams (order 4 to 7) and major lakes and reservoirs. In order to reduce the size of this subset, the line segments were dissolved to remove unncessary segments. Lake data has been selected out to create a subset database afor the Wind/Big Horn project.

 Land Ownership (2003)
Source of ownership data comes from Bureau of Land Management master title plats (MTPs). Using MTPs as a reference ownership lines and attributes were drafted onto mylars of with public land survey (PLS) and digitized. All of the current ownership coverages where snapped to Geographic Coordinate Database (GCDB) where available. The ownership coverages are updated as information is received from the field offices. Updates usually come from users who discover errors or outdated information. Because our focus is mainly on BLM lands, land exchanges made by the Park Service and Forest Service may not show up on our coverages for some time.

 USGS Stream Gages (2005)
The locations of approximately 23,000 current and historical U.S. Geological Survey (USGS) streamgages in the United States and Puerto Rico (with the exception of Alaska) have been snapped to the medium resolution National Hydrography Dataset (NHD). The NHD contains geospatial information about mapped surface-water features, such as streams, lakes, and reservoirs, etc., creating a hydrologic network that can be used to determine what is upstream or downstream from a point of interest on the NHD network. An automated snapping process made the initial determination of the NHD location of each streamgage. These initial NHD locations were comprehensively reviewed by local USGS personnel to ensure that streamgages were snapped to the correct NHD reaches. About 75 percent of the streamgages snapped to the appropriate NHD reach location initially and 25 percent required adjustment and relocation. This process resulted in approximately 23,000 gages being successfully snapped to the NHD.
