Lake Frank Professional Guide
Detailed Trail Description from our Guidebook
"From its source in northern Montgomery County, Rock Creek journeys 33 miles to end at the Potomac River in the District of Columbia. In 1890 the federal government designated some land around the creek as a national park. This park extended its arm from Georgetown to the district’s border with Silver Spring, where it becomes Rock Creek Regional Park. The latter was established in the 1930s to provide green space for local residents.
The 54-acre lake controls flood waters, reduces the sediment load in Rock Creek, and provides a peaceful place for people and a sanctuary for birds and other wildlife. Swimming, boating, and ice skating are prohibited on the lake, but fishing is allowed with a permit. The area around Lake Frank has 8 miles of trails, which includes a 3.25-mile trail that circumnavigates the lake."
