Choptank River

The Choptank River is a major tributary of the Chesapeake Bay and the largest river on the Delmarva Peninsula. Running for 71 miles (114 km), it rises in Kent County, Delaware, runs through Caroline County, Maryland and forms much of the border between Talbot County, Maryland on the north, and Caroline County and Dorchester County on the east and south. It is located north of the Nanticoke River and its mouth is located south of Eastern Bay. Cambridge, the county seat of Dorchester County, and Denton, the county seat of Caroline County, are located on its south shore.

Its watershed area in Maryland is 1,004 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 (1,080 km²), or 48% of the land area.

The $155 million Hyatt Regency Chesapeake Bay Golf Resort, Spa & Marina is situated on the east shore in Cambridge, MD. Completed in 2002, the resort is the only of its kind in the Mid-Atlantic United States. However, Hyatt has been struggling to make bond payments on the property.
