- Abstract
The article discusses research which evaluates contributions at the watershed scale of nonpoint source pollution in critical source areas (CSAs), which are areas with disproportionately high pollutant losses. The identification and evaluation of watershed-scale CSAs allows state and federal programs to implement conservation measures for soil and water where they are most needed. The team used the U.S. Soil and Water Assessment Tool to identify and quantify sediment and phosphorus (P) loads that originated from watershed-scale CSAs. They synthesized their research with CSA targeting studies performed in six Oklahoma watersheds with priority ratings, from 2001-2007. The purpose of the study was to aid the Oklahoma Conservation Commission to prioritize subsidized conservation measures.
