Abstract:

Carbondale No. 4 Dam is a masonry dam with earthfill to the top of the dam along the upstream face and earthfill to within 3 to 10 feet of the top of the dam along the downstream face. The dam extends about 580 feet across the valley and is 28 feet high at maximum section. The spillway, an integral part of the masonry dam, is located near the right abutment. It has a rounded crest, and the crest length is 100 feet. Based on visual inspection, available records, calculations and past operational performance, Carbondale No. 4 Dam is judged to be in good condition. The existing spillway can pass 59 percent of the Probable Maximum Flood PMF without overtopping of the dam. The spillway capacity is rated as inadequate. A stability analysis performed for this report indicates that the dam is apparently stable for the maximum loading condition.
