The Antietam-Conococheague Watershed Alliance (ACWA) is a group of citizens who are passionate in protecting   and restoring the Antietam & Conococheague Creeks and their tributaries as a healthy environment for recreation, animal habitat and improved water quality.  Much work goes into educating the community about the impacts we have on the Antietam & Conococheague Creeks.

The Antietam & Conococheague Creeks are tributaries of the Potomac River and stretch across two states, Pennsylvania and Maryland. The Antietam Creek crosses through the Antietam Battlefield, home to the bloodiest battle of the American Civil War.

Both creeks are host of several stone arch bridges that were focal points during the Civil War and continue to be historical attractions for visitors of the region.

Despite the rich cultural importance of this tributary, for years the creeks lay abused by negligent farmers and urban citizens alike. Waste runoff from farms and trash from cities impacted the creeks such that they were almost completely devoid of life.

In 2006, a group of concerned citizens formed ACWA in hopes of addressing the water quality of the creek as well as raising awareness among citizens of the watershed. ACWA worked with the Antietam Creek only until 2014, when the Conococheague Creek was added to the Alliance.

Since its inception, ACWA has initiated the annual Rubbish Roundup- an event during which volunteers, in cooperation with local government and business entities, scope out the creek by foot or by boat, removing any trash in their path. In previous years, over 150 volunteers have removed or recycled over 2 tons of trash from the creek in just one day!

ACWA also works in partnership with Maryland’s Adopt-A-Road project in maintaining a road within the watershed. The organization also works in partnership with the Chesapeake Bay Trust to promote tree planting along the creek banks, helping to prevent erosion in vulnerable locations.
