Magothy River Watershed

Watershed Description

The Magothy River Watershed is situated in the northeastern portion of the County. It includes the communities of Gibson Island, Long Point, Boulevard Park, Lake Shore, Deerfield, Farmington Village, Earleigh Heights, Cryress Landing, Severna Gardens, Cape Arthur, Manhattan Beach, Old Station Estates, Jones Station, Mago Vista, College Manor, Ulmstead, Bay Hills, Shore Acres, Cape St. Clair, Podickory Point and Revell Downs.

The drainage area of the Magothy River Watershed is approximately 22,802 acres and contains approximately 74 miles of streams draining 68 sub-watersheds. The 68 sub-watersheds range in size from 3 to 1,429 acres. Major tributaries include Magothy Branch, Cockey Creek, Cattail Creek, Cypress Creek, Deep Creek, Dividing Creek and Cornfield Creek.

Many sensitive environmental features including bogs, wetlands, Greenways, and Critical Areas are present within the Magothy River Watershed. Each of these features is important because they provide hydrologic, water quality, and habitat benefits. Wetlands are found throughout the Magothy River Watershed, while bogs are primarily located in the north portion of the watershed. 

There is a mix of land use and land cover in the Magothy River Watershed. Residential development collectively represent nearly 54% (~11,000 acres) of the watershed while forests occupy a substantial area of 31.7%. The areas covered by commercial areas, transportation uses, industry, open space, and agricultural activities are all individually less than 5%. Impervious surfaces represented by roads, building footprints, parking lots and other hard surfaces cover approximately 22% (~4,900 acres) of the Magothy River watershed.

The Magothy River watershed includes a portion of the MD Route 2 (Ritchie Highway) corridor from Arnold Road in the south to Jumpers Hole Road in the north. This corridor contains several shopping centers and office buildings including Anne Arundel Community College. In addition, it is home to several County parks including Lake Shore Athletic Complex, Lake Waterford Park, Kinder Farm Park and portions of Broadneck Park and Sandy Point State Park. Other landmarks include Bay Hills Golf Course, Severna Park Community Center and Grey's Creek Bog Natural Area.

Watershed Assessment

The Watershed Protection and Restoration Program utilizes a watershed based approach to restoring and protecting our waterways. Assessments are conducted on each of the 12 primary watersheds to evaluate water conditions, establish priorities and goals for improvement, and take actions designed to restore or protect water quality.

A comprehensive watershed assessment for the Magothy River watershed has been completed. The reports include a discussion of the water quality problems and sources of pollution and strategies for improving the water quality in the watershed. Click here to read more.
