Current conditions[edit]
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. Portions of the stream flow through Little Falls Stream Valley Park in Bethesda[4] and next to the Capital Crescent Trail. The stream runs near the Dalecarlia drinking water treatment plant in Washington and occasionally has received overflow discharges from the plant.[5]
According to a study conducted by the county government, the water quality of the stream and its tributaries is poor, due to water pollution from urban runoff, as well as the channelization described above.[6] The county and the Town of Somerset have installed several stream restoration projects throughout the watershed.[7][
