The objective of this research was to evaluate spatially and temporally variable phosphorus loading to the Ross Barnet Reservoir in east-central Mississippi using a modeling approach. Modeling methods were developed to model livestock, poultry, and human sources of nutrients from the Upper Pearl River watershed (UPRW-7,885 km2).The Soil and Water Assessment Tool (SWAT) model was applied to evaluate average monthly flow, sediment, total nitrogen (N), and total phosphorus (P) loading to the Ross Barnett Reservoir inlet.
