Little Rocky Run and Johnny Moore Creek Watershed

map of watershed areaLocation
The Little Rocky Run and Johnny Moore Creek watersheds (7.4 square miles and 5.3 square miles, respectively) are located in the southwestern part of Fairfax County and drain south directly to Bull Run/Occoquan River system.

Major Streams and Tributaries
Little Rocky Run: The major tributary is Willow Springs Branch.
Johnny Moore Creek: The major tributary is Polecat Branch.

Unique Features
The Johnny Moore Creek watershed is located in the Watershed Protection Overlay District. This zoning district was established in 1982 by Fairfax County in a progressive move to protect the Occoquan Reservoir, a major source of drinking water for the county. This designation restricts development to one residential dwelling unit per five acres, thereby protecting the streams draining to the reservoir from the damaging impacts of more intense land development – primarily nutrient and sediment pollution. The Johnny Moore Creek watershed also includes the Twin Lakes Golf Course.

The Little Rocky Run watershed is adjacent to the Johnny Moore Creek watershed, but only the lower portion of the watershed is located in the Watershed Protection Overlay District. The upper portion has therefore been more intensely developed.

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).
