caption_attribution_description: This is a map of the Charleston Harbor watershed, including the Ashley, Cooper, Wando and Stono rivers. I, Karl Musser, created it based on USGS and Census Bureau data.
context_page_description: The Cooper River is a mainly tidal river in the U.S. state of South Carolina. The cities of Mt. Pleasant, Charleston, North Charleston, Goose Creek, Moncks Corner, and Hanahan are located along the river. Short and wide, the river is joined first by the blackwater East Branch and then farther downstream at the tidal Wando River. Almost immediately thereafter, the Cooper Rivver widens into its estuary and unites with the Ashley River to form the Charleston Harbor.
  Long used as an important commercial waterway, the West Branch of the Cooper River was initially connected to the Santee River near its navigation head by the Santee Canal, built in the late 18th century. Though the West Branch still rises as a blackwater swamp in central Berkeley County, its main headwaters have been seamlessly shifted to Lake Moultrie by the 1940s vintage Tail Race Canal. Lake Moultrie is, in turn, fed from Lake Marion by a diversion canal built around the same time period. This artificial rerouting of the Cooper River basin has essentially unified the Santee and Cooper River systems into a single hydrological drainage entity.

  The river was named for Anthony Ashley Cooper, 1st Earl of Shaftesbury and chief Lord Proprietor of the Carolina Colony. Charleston was founded on the western bank of the Ashley River in 1670 (at Charles Towne Landing), before moving across to its current peninsular location ten years later.
  Rice and indigo were heavily cultivated on plantations surrounding the brackish marshland of the Cooper River from the early Colonial through the end of the Civil War periods.  Former plantations along the river include Lewisfield, Mulberry, Middleburg, Quinby and Mepkin, which is now Mepkin Abbey, a Trappist monastery.  Many of these and other structures form the Cooper River Historic District, a national historic district located along both branches of the river.  In addition to the Mepkin Abbey Botanical Garden, nearby attractions include the Cypress Gardens and the Old Santee Canal Park.
  Daniel Island and Drum Island (uninhabited) are adjacent to the river. Cargo terminals, a paper mill, and the former Charleston Naval Base line its shore.  The Patriot's Point naval & maritime museum sits at the mouth of the river. Berthed at Patriot's Point are four museum ships, most notably USS Yorktown, a World War II aircraft carrier.
  Goose Creek, a tributary of the Cooper River was the site of a U.S. Navy submarine base through the late 1990s and functioned as a nuclear weapons handling facility servicing fleet ballistic submarines until the advent of the larger Trident submarine-launched ballistic missile which drove the Ohio-class submarines to require a deeper draft.
