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.

The Arkansas Archeological Survey conducted an archeological survey and testing program for the U.S. Corps of Engineers' proposed Conway Water Supply project in the Cypress Creek basin, Conway County, Arkansas. During a 1978 survey of the reservoir area, 26 archeological sites were recorded. Further surveying of the reservoir area, a spillway area, pipeline and road relocation corridors in the present program resulted in recording 53 additional sites within the direct impact of the project. Pedestrian survey and shovel test survey methods were used to discover sites and shovel tests and 1 m by 2 m excavation units were used for testing sites. A study of selected historic log house sites resulted in the following conclusion: The combination of archeological data with oral and written sources made it possible to document and preserve much information on the past inhabitants of the area, their socioeconomic lifestyles, and their historical heritage.
