North Carolina Water Quality Assessment and Impaired Waters List-303(d) and 305(b) Reports
The federal Clean Water Act Section 303(d), requires the NC Division of Water Resources (NCDWR) to publish a biennial list of impaired waterbodies in need of a management strategy or total maximum daily load (TMDL) for improvement. Section 305(b) of the Clean Water Act requires the state to publish a biennial Integrated Report that prioritizes and combines the 303(d) list with a comprehensive report of water quality conditions in the state.
Monitoring & Watershed Assessments

Executive Summary
Bolin Creek Geomorphic Assessment
A study conducted by Earth Tech to find and assess areas of stream channel instability (erosion or sedimentation) of streams throughout the Bolin Creek watershed, and recommendations for corrective projects.
Triangle Area Water Supply Monitoring Project
The US Geological Survey (USGS) in cooperation with six local governments and TJCOG monitors water supply reservoirs and streams throughout the area to create a long-term database of water quality information.
Triangle J Council of Governments Water Resources
Triangle J Council of Governments has a variety of water resources projects, documents, and information on water supplies in the Triangle region of North Carolina.
