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.
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.
Little Rocky Run and Johnny Moore Creek Watershed Management Plan
