This map service contains GIS data in NAD83 projection from the EPA Office of Water for HUC2, HUC4, HUC6, HUC8, HUC10 and HUC12 polygons for the USDA Watershed Boundary Dataset. It is available as a WFS, WMS, and REST service as well as the native MapServer service.

Derived from 1:250,000-scale USGS HUC 8 boundaries, this dataset represents the soil fine gravel fraction for the western USA. A weighted average was created for each HUC 8 watershed using approximate EMAP physical habitat substrate criteria. The values are expressed as percent by weight.

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...

This data set is a complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the entire United States. This data set consists of geo-referenced digital data and associated attributes created in accordance with the "Federal Guidelines, Requirements, and Procedures for the National Watershed Boundary Dataset; Chapter 3 of Section A, Federal Standards, Book 11, Collection and Delineation of Spatial Data; Techniques and Methods 11-A3" (04/01/2009). http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/index.html . Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downstream hydrologic unit, type...

This dataset included the number of calculated for each 5th level HUC. CE richness was calculated for the aquatic EI by summing the number of pearl dace, the northern redbelly dace x finescale dace hybrid, paddlefish, pallid sturgeon, and sauger per 5th level watershed These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions.

These data sets contain the attributes and indicators associated with aquatic EI and were categorized by size, landscape context, and conditionset in the Northwestern Plains Ecoregion. The data for the Aquatic EI used information from the Aquatic Threat analysis performed by the Missouri River Assesment Program (MoRAP). The MoRAP aquatic threat analysis contains information about each threat analysis attribute, indicator and metric arbitrarily quantified (1,2,3) for the 6th level Hydrological Unit (HUC12). These attributes were calculated for the entire HUC 12, the streams within the HUC 12, or the riparian corridor within the HUC 12. For this analysis MoRAP used arbitrary values were assigned good =3, fair =2 and...
