Interpretive Summary: AnnAGNPS was used to analyze Cheney Lake Watershed, a Special Emphasis Watershed in Kansas, during the Conservation Evaluation Assessment Project (CEAP). Seven best management conservation practice (BMP) scenarios, which would impact sediment and nutrient loading to Cheney Lake, were identified and evaluated regarding the effect of their implementation. One of the major findings was the significance of ephemeral gully erosion. This paper describes the scenarios that were tested, the results of the evaluation, and insights into possible improvements in the evaluation process. One major finding was that better spatial and temporal information regarding precipitation is needed to make watershed simulation models more accurate. Although every effort was made to locate and utilize local weather and climate information, the development of new technologies and additional recording stations would provide more accurate information on a temporal and spatial scale for watershed managers involved conservation practice planning.

Technical Abstract: AnnAGNPS was used to analyze Cheney Lake Watershed, a Special Emphasis Watershed, during the Conservation Evaluation Assessment Project (CEAP). Seven (7) best management conservation practice (BMP) scenarios, which would impact sediment and nutrient loading to Cheney Lake, were identified and evaluated regarding the effect of their implementation. One of the major findings was the significance of ephemeral gully erosion. This paper describes the scenarios that were tested, the results of the evaluation, and insights into possible improvements in the evaluation process.
