Regional Water Quality
The Virginia Department of Environmental Quality (VA DEQ) assesses water quality using water quality standards to designate uses for creeks, rivers, streams and tidal waters in Virginia. There are six designated uses for these waterways, and they are: aquatic life, fish consumption, public water supplies, recreation (swimming), shell fishing, and wildlife.
- A complete listing of impaired waters, reports about the pollutants responsible for violations of water quality standards, and suspected causes and sources of pollutants are available at VA DEQ's website, Water Quality Information and TMDLs.
- Map of Virginia's Major Watersheds.
Chesapeake Bay Watershed
The Shenandoah River eventually flows into the Potomac River and later the Chesapeake Bay. Therefore, all sub-watersheds in Shenandoah River impact the Chesapeake Bay.
- The Chesapeake Bay is on the impaired waters list due to too much nitrogen, phosphorus, and sediment. The US Environmental Protection Agency (US EPA) established the Chesapeake Bay Total Maximum Daily Load (TMDL), which is a comprehensive "pollution diet" with rigorous accountability measures to restore clean water in the Chesapeake Bay and the region's streams, creeks, and rivers.

Local Watershed Information
City of Harrisonburg
The City of Harrisonburg is 17.6 square miles (approx. 11,500 acres), and highly urbanized with substantial impervious surfaces (What's an Impervious Surface?). Harrisonburg drains into six different subwatersheds. (What is a Watershed?) Ultimately, all of these watersheds drain into the Shenandoah River and the Chesapeake Bay (see above). The table below outlines the impairments of each subwatershed.
