Lake Como Dam is a composite structure consisting of an upstream earth embankment and a downstream near-vertical stone wall. The dam is 12.2 feet high and 196 feet long, including spillway. The spillway is located near the middle of the dam, consisting of a 28.3-foot long sharp crested concrete weir, terminating with vertical concrete endwalls. There are no facilities to drain the reservoir. Based on visual inspection, field survey, available records, calculations and past operational performance, Lake Como Dam is judged to be in fair condition. Because the spillway capacity of 535 cfs is less than the estimated 1240 cfs peak discharge of the 100-year flood, the spillway capacity is rated as inadequate. Considering the rotted condition of the plank sheeting to the right of the spillway wall, further deterioration of the sheeting may cause leakage and the stability of the dam could, in time, be affected.
