Accotink Creek near Annandale
Accotink Creek is an urban creek in the Potomac watershed. Like many urban streams, it suffers from bank erosion, leading to high suspended sediment loads, steep banks, and fallen trees.

Trends in nitrogen, phosphorus, and suspended-sediment loads for RIM (2021)
Summary of long-term (1985-2021) and short-term (2012-2021) trends in nitrogen, phosphorus, and suspended-sediment loads for the River Input Monitoring stations. “Improving” or “Degrading” trends are classified as likelihood estimates greater than or equal to 67 percent, whereas “No trend” estimates are greater than 33 and less than 67 percent.
