Middle Potomac Watersheds

map of watershed areaLocation
There are five watersheds comprising the Middle Potomac watersheds group, all of which drain to the Potomac River. These are Bull Neck Run, Dead Run, Scotts Run, Turkey Run and Pimmit Run watersheds. The five watersheds span 26 square miles, of which, 23.9 square miles are in Fairfax County. 

Major Streams and Tributaries
Pimmit Run: Little Pimmit Run, Stromans Branch, Bryan Branch, Saucy Branch, Burke's Spring and Bridge Branch.
The Bull Neck Run, Dead Run, Scotts Run and Turkey Run watersheds all have un-named tributaries.

Unique Features
Tysons Corner and McLean are in this watershed.  It is crossed by major highways such as Leesburg Pike, I-495, Route 123 and the George Washington Parkway. The headwaters of Bull Neck Run, Dead Run, Pimmit Run, Scotts Run and Turkey Run are located adjacent to, in or near Tysons Corner.

Improvement Opportunities
The plans identify areas of opportunity for implementing both structural and non-structural improvement projects such as stream restorations, stormwater facility retrofits, community education and stewardship, streamside buffer enhancements and installation of green stormwater infrastructure (GSI). Proposed projects in the plans have recommended priorities. These lists should not be interpreted as specific implementation schedules or a guarantee that the project will be implemented through the planned Capital Improvement Program (CIP). A full list of active or completed Stormwater projects is available online on at Stormwater Improvement Projects or through Jade (Fairfax County's Comprehensive Mapping Application).
