These tributaries of the Potomac River are located in the far western
area of the County and consist of primarily agricultural and wooded
areas. Furnace Branch is a tributary of the Monocacy, flowing into this
large stream within Frederick County. The Little Monocacy River is located
almost entirely within Montgomery County and does not flow into the
Monocacy River as the name suggests (and many people believe!). The
Little Monocacy enters the Potomac River just downstream of where the
Monocacy River joins the Potomac River in Frederick County.
The headwaters of the Little Monocacy watershed begin in the rural
countryside along Comus Road southwest of the town of Comus. This watershed
is one of the most scenic rural watersheds in Montgomery County. Numerous
farms maintain the rural nature of this watershed for the full length
of the stream system as many of the County's farms are located in this
area. The small towns of Barnesville, Sellman, and Dickerson, all located
in this watershed, represent the only concentrated areas of imperviousness
in the Little Monocacy. Portions of the Little Monocacy drain Sugarloaf
Mountain in Frederick County, with many of the headwater tributaries
well forested.
By the time the Little Monocacy passes under Route 28 near the town of
Dickerson, it has grown into a wide, rapidly flowing cool water stream.
Deep pools and high velocity riffles help to maintain a diverse cool water
fish community here. Nineteen fish species were found here in 1996! Two
species of darters were found, greenside darter and fantail darter. Rock
bass and bluegills were found in the pools and Silverjaw minnows swam
along sandy bottom runs. Large central stonerollers and longnose dace
were found in water flowing so fast that the monitoring crew had trouble
remaining standing. Baseline monitoring of this watershed will occur in
the year 2000. DEP staff also explored the watershed in the Spring of
1997 in order to look for least-impaired stream reaches to add to the
reference stream inventory.

Management Categories
Management of these stream systems occurs almost exclusively through
voluntary actions among agricultural and large lot land owners.
Agricultural Watershed Management Areas
These watersheds are all located in the agricultural preserve area
of the County and are several of our most scenic agricultural watersheds.
| Watershed Management Strategy |
- Continue current practices.
- Use of agricultural BMPs and the application of environmental guidelines
and regulations for limited areas that develop.
- Acquire additional information on the stream conditions in these
areas through baseline monitoring in 2000.
