Patuxent River Watershed Drainages
- Hawlings River Watershed
(Zip Codes draining to this watershed include: 20832, 20833, 20862, 20860, 20861, and 20882)
- Hawlings River Watershed Restoration Action Plan
 (PDF, 12 pp, 991K)
- The Hawlings River Watershed Restoration Study was completed in February 2003. The Hawlings River Watershed Restoration Action Plan is a dynamic document used to track progress in implementing the Study recommendations. To produce the greatest improvements for existing degraded instream habitat, as well as to provide the best opportunities for reductions of sediment and associated pollutants, implementation must include:
- Stream restoration projects throughout the watershed, rather than focusing on only the developed portions
- Agricultural best management practices (BMPs), particularly those targeted to protecting riparian buffers, where possible
- Active stewardship, by both residents and resource users, to control all sources of degradation and to promote the needed stream restoration and buffer enhancement and creation projects.

- Montgomery County's Commitment to Anacostia Watershed Restoration (PDF, 13 pp, 3.3Mb)
- This report describes the County's efforts to repair stream environments damaged by inadequately controlled stormwater runoff in the County's older, more established watersheds. Illustrations of typical sedimentation and habitat loss damage are provided, along with examples of remedial projects that have been built to restore habitat features and support more diverse aquatic communities.
Examples of projects the Department of Environmental Protection has constructed or has under design in the Sligo Creek, Northwest Branch, Paint Branch, and Little Paint Branch watersheds are provided. These streams flow into the regional Anacostia watershed, where watershed restoration efforts are being cooperatively pursued by Montgomery County, Prince George's County, and the District of Columbia. The report presents information on a number of stream restoration and stormwater retrofit projects that have been built or programmed to address problems in Montgomery County's Anacostia tributaries. It also includes related information on funding, the number of stream miles restored, and the number of watershed acres protected by new stormwater management controls.

- The Watershed Restoration Partner Team is conducting a Watershed Study of the Great Seneca Creek and Muddy Branch Watersheds to evaluate stream conditions, identify problems, and propose restoration projects. The Watershed Restoration Partner Team makes extensive use of scientific watershed studies to identify the most severe problems first. The Watershed Restoration Partner Team, which consists of Montgomery County Department of Environmental Protection, Maryland National Capital Park and Planning Commission, U.S. Army Corps of Engineers, and City of Gaithersburg will be assessing the need for improving overall health of the streams by enhancing stormwater management and identifying areas for stream restoration.

- Watts Branch Watershed Restoration Study: Task 1 (PDF, 25 pp, 7.7Mb)
The Watts Branch Watershed Restoration Study is being conducted by the County's Department of Environmental Protection. The purpose of the study is to assess and prioritize potential stormwater management and stream enhancement projects that address the channel erosion and riparian and aquatic resource conditions of the Watts Branch watershed. DEP will use the results from this study in an overall watershed plan to protect and improve conditions in the Watts Branch watershed.
The watershed plan will include public outreach, capital projects, and volunteering opportunities. This Task 1 report summarizes the existing conditions in the watershed. In addition, it discusses the methods used for identifying and prioritizing impaired subwatersheds and presents the results of that exercise. The Task 2 and Task 3 reports will follow in the future, containing specific projects, designs, prioritizations, and implementation recommendations.
