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.

The Desert Landscape Conservation Cooperative Watersheds Map shows hydrographic features including watersheds, streams and lakes at a regional scale. The files provided are graphic design files that can be used to plot a publication-quality, poster-size map. Scale: 1:2,500,000Map poster dimensions: 34 x 44 inchesData sources: Watershed boundaries are from the North American Environmental Atlas by the Commission for Environmental Cooperation, 2010. Hydrography, roads, populated places, and political boundaries are from the National Atlas of the United States, 2004. Natural Earth 1:10m Physical Labels (3.0.0) are derived from Patterson’s Physical Map of the World, 2008.File descriptions: DLCC_Watersheds.ai is an...

This data set is a complete digital hydrologic unit boundary layer of the Subbasin (10-digit) 5th level for the entire United States, clipped to the Northeast. A hydrologic unit (HU) is a drainage area delineated to nest a multi-level, hierarchical drainage system. Its boundaries are defined by a hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream, or similar surfaces waters. An HU can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. HUs are only synonymous with classic watersheds...

The Hydrologic Unit Code (HUC) is part of a hierarchical classification system for surface water drainage in the US (Seaber et al. 1987). The numerical code represents a “cataloging unit” of delineation. Vector format (i.e. polygon) data were compiled from United States Geological Survey (USGS) source - the Watershed Boundary Dataset (WBD). For this project the dataset was modified by removing duplicate codes, removing duplicate polygons, and editing the line work to include near shore habitats in both the coast lines and within large water bodies. The coastal polygons were expanded 5 kilometers from landward edges to create a consistent coastal boundary. This altered 12-digit code HUC dataset was used to delineate...

This data set is a complete digital hydrologic unit boundary layer of the Subbasin (12-digit) 6th level for the entire United States, clipped to the Northeast.

Its boundaries are defined by a hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream, or similar surfaces waters. An HU can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points.

Aquatic Ecological Focus Areas were based on The Nature Conservancy’s priority streams and by the Special Aquatic Life Use streams defined by the Kansas Department of Health and Environment, with some exclusions based on expert opinion. The selected streams were buffered by 100 m; 12-digit HUCs that intersect the buffers comprise the EFAs.
