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...

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 risk of flow alteration (RFA) due to evaporative loss from artificial water bodies in local catchments for the 14-state SARP region. Â The amount of water body surface is based on high resolution NHD and linked to NHD+ catchments. Â The risk is based on the percentage of the catchment land surface covered by artificial water bodies (100 x water body surface area / watershed surface area) Risk of flow alteration categories: Â Â Â Â Â Â Â Â Â ZERO -Â Â Â Â Â Â 0% land covered by artificial...
