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 HIGH – >100%, [...]
