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 water bodies, Â Â [...]
