A methodology was developed for identifying and assessing rural nonpoint source pollutiof problems by the Ohio-Kentucky-Indiana Council of Governments (OKI). The OKI model is based upon the Universal Soil Loss Equation utilized by the Soil Conservation Service (SCS). For each of the 226 rural watersheds, the OKI model and the approach for assessing rural nonpoint sources provided an estimate of the nonpoint source loadings, an identification of problem uses within watersheds, and a means of evaluating alternative management practices for alleviating identified problems. Model results indicated that gross erosion ranged from 0.02 to 32.5 tons per acre per year under existing conditions and provided estimates of sediment, nutrient, and organic matter loads. The model results and supporting information were used to develop a rural nonpoint source control program which keys on the effective application of management practices in prioritied problem areas, and demonstrates the need for an increased Agricultural Conservation Program through local Soil and Water Conservation Districts.
