Approximately half of the Patuxent River’s 110 miles is tidal, tying it directly to the Chesapeake Bay. It is the largest Chesapeake Bay river located entirely in the state of Maryland. The river’s mouth is at the harbor of Solomons Island. The lower portion of the river is bordered by wetlands, such as the Jug Bay Wetlands Sanctuary, that provide vital breeding and nesting grounds for birds like osprey, bald eagles, and blue herons. Additionally, over 100 species of fish live in the Patuxent River. The river is heavily affected by human activity such as mining, ironworks, and sprawling urban development.
