The drainage area of the South River Watershed is approximately 36,433 acres. It contains approximately 246 miles of streams divided into 59 sub-watersheds. Major tributaries include Broad Creek, Beards Creek, Church Creek, Glebe Creek, Crab Creek and Harness Creek. From its headwaters in Crofton, the river enters the Chesapeake Bay south of the City of Annapolis, hence the name South River.

The land acres are divided as follows: urban 14,251 acres (39%), agriculture 5,472 acres (15%), forest 16,669 acres (46%), wetlands 132 acres (<1%) and barren land 4 acres (<1%).  Impervious surfaces represented by roads, building footprints, parking lots and other hard surfaces cover approximately 12% (~4,432 acres) of the South River watershed. Major landmarks in the South River watershed include Annapolis Towne Centre at Parole, Festival at Riva, Annapolis Harbour Center, Eisenhower Golf Course, Anne Arundel County Fairgrounds, Walden Golf Course, Lee Airport and South River Golf Links.

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 South 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.
