Early land records in 1715 cite Captain John's Run, now Cabin John Creek. The toponym "Cabin John" is thought to be a corruption of the name "Captain John", but the origin of the name remains unresolved.[4]
Course
The headwaters of the creek originate in the city of Rockville. The Cabin John Stream Valley Trail[5] follows the course of the creek for 8.8 miles (14.2 km), passing through Cabin John Regional Park[6] and Cabin John Local Park.[7] The Union Arch Bridge carries MacArthur Boulevard and the Washington Aqueduct over the stream about 1/4 mile before the creek flows through a culvert under the Chesapeake and Ohio Canal and empties into the Potomac River near Cabin John, Maryland.
Water pollution
The Cabin John Creek watershed is highly developed, and as a result the water quality in the creek main stem and several tributaries is degraded.[8] Montgomery County Government is implementing a long-term plan to improve water quality throughout the area, including stormwater management and stream restoration projects.[9] As of 2021 the county has installed restoration projects on the Booze Creek and Buck Branch tributaries.[10][11]
