Abstract : The ten plans of improvement considered all seek to reduce the cost of maintaining authoritzed depths in the navigable channels. of Charleston Harbor. The various plans take two basic approaches: (1) they eliminate or restrict release of water at Pinopolis or, (2) they permit unrestricted release of water at Pinopolis. Those plans falling into the first category include the provision of steam generation capacity to replace the present hydro power capacity (with the surplus water to be spilled into the Santee River), or the provision of an alternate hydro power installation inthe vicinity of St. Stephen, S. C., which would dispose of these waters by discharge in to the Santee River. Three separate plans were studied in which alternate hydroelectric plants were considered. Plans falling under the second category (above) include three simple rediversion canal routes that divert Pinopolis releases from the harbor, and two rediversion plans that divert the waters of the upper Cooper and later readmit it into the lower harbor; and one plan, a general channel rectification plan, which would deepen, widen, and straighten the upper Cooper River with an eye toward reducing velocities, thus preventing erosion of the channel. All of these plans are discussed in detail.
