The Patuxent River is the largest and longest river in the state of Maryland, spanning 908-square-mile in size. It is a tributary of the Chesapeake Bay and one of the three major river drainages in central Maryland. The other two are the Potomac River to the west, which runs through Washington, D.C., and the Patapsco River to the northeast, which runs through Baltimore.

From its origin in the hills of Maryland Piedmont 115 miles away from the Chesapeake,  the Patuxent River runs between Baltimore and Washington D.C. in a generally southeastward direction, before it flows into a passable tidal estuary in Prince George’s County.
