Cooper River Rediversion Project, Lake Moultrie and Santee River, South Carolina. Requirements for Protection of Bushy Park Reservoir. Supplement 2.

The results of previous studies indicated that rediversion of a major portion of the Santee River flow from Cooper River back to the Santee River is the best way to obtain a substantial reduction in maintenance dredging in Charleston Harbor. However, continuation of as much flow as possible through Pinopolis was considered desirable to minimize change to the Cooper River and harbor environment and to accommodate downstream needs of Bushy Park Reservoir at mile 43 and the Jefferies Stream Electric Generating Plant just below Pinopolis. The purpose of the model study was to determine the effects on tidal heights, current velocities, and salinities of various weekly hydrographs at Pinopolis which could result from the proposed rediversion project. The existing hydrograph has a weekly average flow of 15,600 cfs. Five suggested rediversion schedules were tested, including three with a weekly average flow of 3000 cfs and two with a weekly average flow of 3500 cfs.
