Abstract
Russell Elsey Dam is an earth dam constructed for recreational purposes. The dam is approximately 800 ft long and 21 ft high. The main spillway is ungated and located at the west end of the dam (left abutment). An auxiliary spillway, also ungated, is located on the east end (right abutment). The normal pool elevation is controlled by two overflow pipes near the main spillway. There is also what appears to be a low level outlet for reducing the pool elevation. The operability of the low level outlet is unknown. Our evaluation indicates the dam is in generally poor condition. Hydrologic/hydraulic analyses indicate that the spillway will not pass the 10 percent probability-of-occurrence (10-yr flood) event without overtopping the dam. These analyses also indicate the dam will be overtopped for a hydrologic event which produces greater than 11 percent of the Probable Maximum Flood.
