The Salt Water Barrier was a proposed project on the estuary of the Delaware River, which was projected in the late 1950s to convert the lower reaches of the Delaware into a freshwater lake. The barrier was proposed as a 30-foot (9.1 m) high dam near New Castle, Delaware, 53,300 feet (16,200 m) long, equipped with locks for the passage of shipping to Wilmington and Philadelphia. A study for the project was authorized by Congress in 1958, with engineering evaluations and public hearings by the U.S. Army Corps of Engineers. The prime purpose of the project was to develop the lower river as a source of drinking water for communities along the lower river. Objections to the barrier included concerns about the oyster industry, shipping constraints, increased shoaling, ice formation, and most importantly, the possibility of trapping pollutants above the barrier. The project was found to be technically feasible, but not economically practical. It was not included in the final Delaware River Basin Report of 1962, which proposed reservoirs higher in the Delaware River basin, and no further action was taken.
