Small Watershed Action Plan (SWAP)

A Small Watershed Action Plan (SWAP) identifies strategies to bring a small watershed into compliance with water quality standards. Strategies go beyond traditional government capital projects and include actions in partnership with local watershed associations, citizen awareness campaigns and volunteer activities. A Small Watershed Action Plan has been prepared for the Tidal Gunpowder watershed in conjunction with the Middle River watershed. Review updates on the plan.


To participate in watershed activities, contact your local watershed association. For the Tidal Gunpowder watershed, contact the Gunpowder Valley Conservancy.
