National Dam Safety Program. River Cement Co. Lake Dam (MO 30420), Mississippi - Kaskaskia - St. Louis Basin, Jefferson County, Missouri. Phase I Inspection Report.
Abstract
Based on the visual inspection, the present general condition of the dam is considered to be satisfactory. The following deficiencies were noticed during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam. A minor collection of floating debris is lodged within the drop inlet spillway structure at the upstream end of the outlet pipe. An accumulation of debris within the spillway structure can obstruct the outlet pipe resulting in a loss of discharge capacity and unwarranted flooding of the lake. Several beaver dams exist within the downstream channel between the dam and the juncture of the channel with Cliffdale Hollow, a distance of about 1,000 feet. Damming of the channel is believed to be responsible for the tailwater pool that lies adjacent to the downstream toe of the dam. In addition, the outfall channel that lies between the outfall structure and the downstream channel is partially obstructed by small trees and brush.
