Robeson Creek, located in Chatham County, North Carolina, is a 303 (d) listed stream due to chlorophyll a violations and impaired biological communities. Pollutants associated with the chlorophyll a violations are nutrient inputs from point and nonpoint sources within the watershed. The North Carolina Division of Water Quality (DWQ) began monitoring water quality of Robeson Creek and its tributaries in December 2000. DWQ has developed a Total Maximum Daily Load (TMDL) for total phosphorus in this watershed. North Carolina State University (NCSU) in coordination with DWQ, the Robeson Creek Technical Advisory Committee and other stakeholders in the watershed has developed a TMDL implementation plan to address nonpoint sources of phosphorous in the Robeson Creek watershed. As part of the implementation plan, NCSU performed a watershed assessment to refine identification of pollutant types and sources as well as critical areas for implementing Best Management Practices (BMPs) at the subwatershed level.

This paper will present an overview of the development process used for the TMDL implementation plan for the Robeson Creek Watershed.
