Local interests expressed the desire for a shallow draft navigation channel from Charleston to Columbia, South Carolina, a distance of approximately 170 miles. Shallow draft navigation presently exists for approximately 120 miles of this distance. This was made possible by construction of the Santee-Cooper hydroelectric project which constructed dams across the Santee River and Cooper River and formed large fresh-water lakes. Also constructed in the dam on Cooper River was a 60 x 180 navigation lock at Pinopolis, South Carolina. The most practical plan of improvement consists of canalization of the Congaree River to Columbia by a series of 3 locks and dams. Consideration was given in the design of the structures to the prevention of flooding of the extensive forested areas along the river and to the unimpeded, upstream migration of the striped bass population during the spawning season and the downstream transport of the maturing eggs. Plan A considered lock sizes of 84 x 600 for the Congaree River and would include a new lock of the same dimension to replace the existing lock at Pinopolis. Plan B considered lock sizes of 84 x 400 for the Congaree River and extension of the Pinopolis lock by 58 feet. Commercial navigation on the Charleston to Columbia waterway has been practically nil for the past 15 years. Prospective traffic which could be generated was found to be insufficient to justify the construction of the project.
