Abstract:

The dam appears to be in poor condition. No maintenance program exists for the dam and the lack of maintenance has led to a general deterioration of the structure. An upstream shut-off exists for the 12 in. drainline, but the capability of the valve to operate is questionable. Wet areas were observed on the downstream slope of the dam. One area observed at the right abutment contact and a second wet area was observed on the downstream slope adjacent to the right spillway wingwall, approximately 10 feet below the right crest. The seepage should be investigated to ascertain its effects on the stability of the structure. The spillway is in a deteriorating condition and the concrete in the channel walls and channel bottom should be repaired. Undercutting of the channel floor if left unchecked could lead to the potential failure of the spillway structure. Brush and small trees were observed on the upstream and downstream slope. The brush and small trees should be removed in a controlled manner. Author
