Located in the Palisades neighborhood of Washington DC, Battery Kemble creek is a great spot for recreation. The water body and park are named for Battery Kemble, a civil war fortification which dates back to 1862. The park offers a walking trail with historical markers, picnic tables, and has limited parking just inside the entrance off of Chain Bridge Road, with a larger lot at the end of the entrance drive.

**WARNING: SWIMMING IS PROHIBITED IN D.C. WATERS REGARDLESS OF THE CURRENT STATUS**

Despite its designation as a Class A Primary Contact waterway, the DC Department of Health (DOH) bans swimming in the Potomac River citing the risk of high bacteria levels after rainstorms as the only reason it is considered “unsafe” to swim. The activation of the Clean Rivers Project in DC is expected to reduce system wide combined sewage overflow by 96%, bringing the Potomac significantly closer to a swimmable river.

Water quality standards as well as the methods used to determine pass or fail status vary widely across jurisdictions and monitoring programs. We encourage users to explore the sample data in addition to checking the swim guide status.
