On Saturday, September 26, 2026, from 9 a.m. until 12 p.m. (rain date October 3, 2026), Prince William Trails and Streams Coalition (PWTSC), a 501(c)3 organization, is conducting its 17th annual clean-up of the upper Occoquan River, from nine different sites along 25+ miles of the Occoquan River. The cleanup ranges from Cedar Run/Broad Run through Lake Jackson, from the base of Lake Jackson Dam to Hooes Run (south of Lake Ridge Marina), and to Belmont Bay Community. Stormwater drainages and ponds are not left out during this community water quality awareness event.
From 2022 to 2025, over 300 volunteers on both water and land collected over 10,600 pounds of trash, putting in over 930 hours of volunteer time
