Река Чоптанк: География и характеристики

River in Delaware and Maryland, United States
Its watershed area in Maryland is 1004 square miles (2,600 km2), of which 224 square miles (580 km2) is open water, so it is 22% water. The predominant land use is agricultural with 418 square miles (1,083 km2), or 48% of the land area. The river is named after the native Choptank people.

The Choptank River begins at Choptank Mills, Delaware, where Tidy Island Creek and Culbreth Marsh Ditch join together. It ends at the Chesapeake Bay in a very wide mouth between Blackwalnut Point on Tilghman Island, and Cook Point, near Hudson, Maryland. Tidy Island Creek and Culbreth Marsh Ditch rise in western Kent County, Delaware. The entire watershed is in the coastal plain. The Choptank reaches sea level near Denton, Maryland, and is not salty until around 2 mile (3 km) below Denton.

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. Knapp’s Narrows offers a shortcut to boats approaching from the north.

Its main tributaries are the Tred Avon River and Tuckahoe Creek on the north side, and Cabin Creek and Hunting Creek on the south side. There are several small creeks on the northern shore, including Harris Creek, Broad Creek, Irish Creek, Island Creek, La Trappe Creek, Bolingbroke Creek, Mile Creek, Kings Creek, Forge Branch and Broadway Branch. On the southern shore the small creeks include Jenkins Creek, the Warwick River, Marsh Creek, Maryland, Skeleton Creek, Mitchell Run, Hog Creek, Fowling Creek, Robins Creek, Church Creek, Williston Creek, Watts Creek, Chapel Branch, Spring Branch, Gravelly Branch and Cow Marsh Creek.
