Deer Creek is a 52.9-mile-long (85.1 km) river in Maryland that flows through the scenic areas of Harford County and empties into the Susquehanna River, roughly halfway between the Interstate 95 bridge and Conowingo Dam. Its watershed area is 171 square miles (440 km2). Its watershed area in MD (excluding water) is 145 square miles (380 km2), with 3% impervious surface in 1994. It serves as a divider between the agricultural and urban/suburban areas of Harford County.
Deer Creek rises in Shrewsbury in York County, Pennsylvania, and flows southeast, soon entering Maryland. It cuts across the northeastern corner of Baltimore County and into Harford County, where it runs through Rocks State Park, Palmer State Park, and Susquehanna State Park, passing north of the Bel Air area.
Deer Creek supported the last known population of the Maryland darter, the only endemic vertebrate in Maryland [3]. The creek is commonly used for recreation in the summer months.
The Deer Creek Bridge, Stewartstown Railroad carries the Stewartstown Railroad over Deer Creek in Hopewell Township and Shrewsbury Township, Pennsylvania.
