Heavy siltation of Charleston Harbor has caused the US Army Corps of Engineers to consider plans to divert the major flow of fresh water through a new canal to be constructed from the Lake Marion-Lake Moultrie-Cooper River complex to the Santee River. The US Geological Survey was asked to study the effect such a canal would have on the ground-water regimen of the area. The drilling phase of the study consisted of 33 core holes located along and at right angles to the canal right-of-way. The purposes of the core holes were to delineate the subsurface geology and to locate possible sites for the observation well network. As a result, 20 observation wells were drilled in order to monitor water levels before, during, and after construction of the canal and power house. As a result of the drilling program three aquifers in the study area were delineated aquifer 1, a shallow 40-60 feet sand which supplies limited amounts of water to wells aquifer 2, a confined limestone 90-120 feet which is the most widely used aquifer in the vicinity of the canal right-of-way and aquifer 3, a sand and gravel remnant of a buried stream channel found in the flood plain.
