Little Falls Branch (Potomac River tributary)

Little Falls Branch, a 3.8-mile-long (6.1 km)[1] tributary stream of the Potomac River, is located in Montgomery County, Maryland.

In 1895 construction was completed to fully divert the stream from the Dalecarlia Reservoir and the branch stopped providing water to the city.

[5] Planning for the Little Falls parkway started in the mid-1940's and the county began buying land with a 20 acre purchase on both sides of Massachusetts avenue in 1946.

In 1978, the National Capital Planning Commission approved a trail to run the length of the park, along with a replacement sewer line to be built south of Massachusetts Avenue.

[10] In 1980 the Washington Suburban Sanitary Commission built the sewer line through the park, replacing one that was leaking and in 1981 a bike trail was added on top of it.

[13] Today Little Falls Branch flows through a highly urbanized area, and parts of the stream have been altered through construction of underground pipes, culverts and open concrete channels.
