The intent of this data is to identify watersheds where Region 4 Fisheries Program work should be focused. Â Additional on-the-ground assessments may be necessary to verify conditions. Â The Fisheries Program proposes to work across Programs and with partners to identify conservation needs within the selected watersheds, and identify joint efforts and projects to leverage resources to maximize efficiency. These actions may include such projects as habitat improvements, barrier removal, propagation, and genetic conservation.

Ecologically relevant river size classes for NHDPlus v1 flowlines in the 14 state SARP region. Size class was determined for each river flowline using the cumulative drainage area from NHDPlus v1 dataset. The data are scaled to show the largest rivers at the regional scale. Zoom into the map for smaller rivers, creeks, and headwaters. For more information about how this attribute was developed by the Southern Instream Flow Network (SIFN), go to http://www.southeastaquatics.net/sarps-programs/sifn/instream-flow-resourcesYour comments about this dataset are welcome. Please send comments to the dataset author using the Comment tab below.Â

Risk of altered ecologically significant components of the flow regime due to human impacts. The SARP Flow Alteration Assessment provides a regional characterization of the distribution and risk of altered flow regimes at the NHDPlus segment scale. The human impacts include runoff from impervious surfaces, evaporative losses from artificial water bodies, and surface water use. Impacts of these activities on selected ecologically significant components of the flow regime are given in the attached document. These flow components...

The SARP Flow Alteration Assessment provides a regional characterization of the distribution and risk of flow regime impairment of streams and rivers by anthropogenic sources at the NHD+ segment scale. This map illustrates the cumulative risk of flow alteration (RFA) from surface water use for thermopower generation in Oklahoma.  Water use is based on state permits for surface water withdrawals and returns.  The risk is based on the volume of water used monthly in the drainage area relative to the monthly volume of flow.  Risk of Flow Alteration categories:  ZERO     - 0% mean monthly flow depletion,  LOW      - > 0-10%,  MEDIUM - > 10-20%,  HIGH      - >20-100%, and  PROVISIONAL...

Ecoregions of the SARP region based on Omernik (1987) attributed to NHDplus catchments. Ecoregions are areas with generally similar ecosystems and similar types, qualities, and quantities of environmental resources,. Ecoregion boundaries were determined by examining patterns of vegetation, animal life, geology, soils, water quality, climate, and human land use, as well as other living and non-living ecosystem components. Level IV ecoregions are delineated at the local scale.For more information about this attribute, visit http://www.epa.gov/wed/pages/ecoregions.htm and http://nationalatlas.gov/mld/ecoomrp.html.
