About the Watershed

The Cabin John Creek Watershed is 25 square miles of heavily urbanized land (90% residential/commercial) with its centerpiece being the county's 520 acre Cabin John Stream Valley Park containing the Cabin John Creek and the Cabin John Stream Valley Trail.

The Cabin John Stream Valley Park, the largest stand of forest and trees in the watershed, was acquired in 1934.

The headwaters of Cabin John Creek originate in the City of Rockville then flows south about 10 miles, passing under Interstate 270, through Cabin John Regional Park, under the Capital Beltway (I-495), the historic Cabin John Bridge, and finally to its confluence with the Potomac River at the C&O Canal near the towns of Cabin John and Glen Echo.

Chances are Cabin John Creek or one of its tributaries are not far from where you live, so take a trash bag on your walks and clean up as you go!
