This layer represents the number of Tier 1 fish species known to occur in each HUC10 watershed in the state, according to data available in CPW’s fish database as of December 2014. There are 25 fish species on the Tier 1 SGCN list; a maximum of eight different species occur in the same watershed. This map is an indicator of species richness only; it does not consider relative habitat quality, or population metrics such as density or abundance, across watersheds.

This dataset provides a watershed index of surface drinking water importance, a watershed index of forest importance to surface drinking water, and a watershed index to highlight the extent to which development, fire, and insects and disease threaten forests important for surface drinking water. This tabular dataset is meant to be joined with the NRCS Watershed Boundary Dataset HUC-12. The results of this assessment provides information that can identify areas of interest for protecting surface drinking water quality. The spatial dataset can be incorporated into broad-scale planning, such as the State Forest Action Plans, and can be incorporated into existing decision support tools that currently lack spatial data...

This data used HUC-12 boundary dataset (below) along with elevation, levee and inundation frequency datasets to define an area that is directly affected by changes in river level on the Lower Mississippi River. Used in the GCPO CPA to determine habitat suitable for alligator gar spawning. 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...

Using NatureServe's Digital Distribution Maps of Freshwater Fishes of the Conterminous United States, Version 3.0, a count of species per 8-digit Hydrologic Unit Code was summarized. Â Natural breaks were used to symbolize the layer.

This dataset contains subwatersheds (HUC 12-digit) within basins intersecting the Colorado Plateau, Arizona/New Mexico Plateau, and Sonoran Desert eco-regions in the southwestern United States. It is an extract of the National Watershed Boundary Dataset (WBD), obtained January 2011. For more information on the WBD, see http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/index.html .

This Illinois Valley Landscape Assessment boundary was developed by selecting 12-digit subwatersheds that encompass the agreed upon assessment boundary. These subwatersheds were dissolved into a single boundary. Below is the description of the source data: This data set is a complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the entire United States.
