The Choptank reaches sea level near Denton, Maryland, and is not salty until around below Denton.

Navigability

The river is navigable up to Denton, about 45 miles upriver. The bridge at Cambridge limits traffic to 50 feet vertical clearance. The river’s mouth is marked in the main channel by an abandoned, tilting masonry lighthouse on the underwater Sharps’ Island.
