National Program for Inspection of Non-Federal Dams. Goodall-Sanford Dam (ME-00185), Mousam River Basin, Sanford, Maine. Phase 1 Inspection Report
The Goodall-Sanford Dam is a concrete gravity structure. The dam is approximately 14 feet high and 245 feet long, and has a 213-foot long uncontrolled free overfall spillway. Based on the visual inspection and reports of past operational performance, the Goodall-Sanford Dam is assessed to be in fair condition. Areas of major concern regarding the long-term safety of the dam include deterioration of the concrete at the gated outlet and process water headworks structures, leakage from beneath the east wingwall downstream of the dam, inadequate freeboard between the normal water surface elevation and low areas along the upstream concrete dikes, and the inability of the dam to pass the test flood without overtopping. Based on the dam's small size and high hazard potential, the spillway test flood is one-half the probable maximum flood (1/2 PMF) which has a peak discharge of 8,500 cfs. The spillway discharge capacity is 26 percent of the test flood. The test flood outflow would overtop the west abutment by 1.6 feet and the east abutment by 0.6 feet.
