While in South Carolina conducting his survey, Murray envisioned a system much larger than Williams's plan for one dam on the Santee River. Murray envisioned a system of three dams, one at the site on the Saluda, which, in addition to power generation, would keep a constant flow of water into the Santee where another dam would bring the water of that river together with the Cooper River on a vast diversion dam that fed the water into a power canal with a third dam and power house. The dimensions of the project quickly overshadowed the 60,000 horsepower (40 MW) system that Williams envisioned and grew to over 400,000 horsepower (300 MW).
