Piscataway Creek is an 18.6-mile-long (29.9 km)[1] tributary of the Potomac River in Prince George's County, Maryland. The creek is a tidal arm of the Potomac for its final 2.5 miles (4.0 km), entering the Potomac at Fort Washington Park. Tinkers Creek is a tributary to Piscataway Creek, converging from the north 4.5 miles (7.2 km) upstream of the mouth of the Piscataway.[1] The United States Geological Survey records two variant names for Piscataway Creek: Pascattawaye Creek and Puscattuway Creeke.[2]
The Fort Washington Light was built to provide guidance for mariners entering Piscataway Creek from the Potomac River.
