Little Seneca Creek
Encyclopedia
Little Seneca Creek is an 14 miles (22.5 km) stream in Montgomery County
, Maryland
, roughly 18 miles (29 km) northwest of Washington, D.C.
The creek
drains portions of Clarksburg
, Germantown, and Boyds
. It rises south of Damascus
and flows southward about 4.8 miles (7.7 km) to Little Seneca Lake
, a reservoir
created by construction of a dam
on the creek. The reservoir empties to the lower portion of the creek, which flows south about 6.6 miles (10.6 km) to Seneca Creek
, which drains to the Potomac River
and the Chesapeake Bay
.
A portion of the creek below the lake is a cold water stream that supports natural rainbow trout
and brown trout
populations.
and imposed some restrictions on housing development and other new construction
in part of the watershed, in order to preserve water quality
before development accelerated. A "Special Protection Area" was designated that requires additional controls for stormwater
runoff
, beyond those required of all new projects.
However, the county reported that its recent requirements for new construction projects have not been sufficient to prevent water quality impairment. Several large land development projects were constructed in Clarksburg and elsewhere in the watershed over the past several years. The county conducted biological monitoring
of stream conditions and has documented declines in water quality associated with the new construction. More comprehensive site designs to minimize stormwater runoff, such as conservation design or low impact development
designs, are recommended.
