Arkansas River and Tributaries Arkansas and Oklahoma. Toad Suck Ferry Lock and Dam, Conway Water Supply Foundation Report
This report describes the foundation conditions encountered during the construction of a water supply dam for the city of Conway, Arkansas; such to replace a previous water supply that was adversely affected by the construction of the McClellan-Kerr Arkansas River Navigation System. The dam was founded on a thick shale layer of the Atoka Formation. Locally, the shale was gray to black, hard to moderately hard, sandy, and well compacted. Excavation of a 10-foot wide centerline cutoff core trench in the shale posed no problems with standard earth-moving equipment. Pre-split blasting was required in excavating the outlet works stuctures and emergency spillway. The report gives the results of a well-point dewatering system installed in the valley section that did not function adequately, and methods to overcome ground-water flow at the rock/overburden contact. Foundation preparation and treatment consisted of wash/air jetting, mortared open joints, concrete fillets, and rock anchoring. The report details the installation of a grout curtain utilizing the stop-grouting, split spacing method.
