Abstract:

Lake Windsor Dam, classified as having significant hazard potential, is in fair overall condition. There is seepage of water and spongy ground at the downstream toe of the embankment and erosion on the embankments. The embankments are covered with thick brush and trees. The riprap on the upstream face and the toe of the spillway is deteriorating and becoming dislodged in areas. Numerous cracks exist in the concrete of the spillway chute. The control of the low level outlet slide gate is not visible and its operating condition is unknown. There is essentially no available information concerning the design, construction and operation of the dam. Additional investigation is necessary to adequately evaluate the future performance of the dam. The spillway capacity as determined by the Corps of Engineers Screening criteria is adequate. The following are recommended to be done soon Remove debris which has accumulated in the spillway discharge channel. Investigate the operating condition of the low level outlet and repair if necessary. Provide safe access to the control for operating the low level outlet. Repair cracked and spalled concrete in the spillway structure. Repair deteriorated or dislodged riprap on the upstream embankments and at the downstream toe of the spillway. Repair eroded areas on the embankments of the dam. Develop written operating procedures and a periodic maintenance plan to ensure the safety of the dam.
