Abstract:

The Fienup Lake Dam was visually inspected. The purpose of the inspection was to assess the general condition of the dam with respect to safety and, based upon this inspection and available data, determine if the dam poses a hazard to human life or property. Based on a 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 Several small trees exist on the upstream slope near the west abutment of the dam. The tree roots may, in time, provide a pathway for lake seepage that could develop into a piping condition. At the time of the inspection, the grass on the downstream slope was on the order of 30-inches high. Grass should not be allowed to grow to a height that provides cover for burrowing animals or hinders inspection of the dam. The pump used to provide lake make-up water was reported to be without a means of preventing pump flow on a continuous basis. Without a spillway or other means to ensure lake surface elevation, there exists the possibility of overtopping the dam due to continued pumping.
