The dam is a 400 ft. long, 25 ft. hydraulic height earth fill embankment structure, with a small concrete outlet structure near the right abutment. Visual inspection indicated the dam to be in generally fair condition. Erosion was observed growing on both the upstream and downstream slopes. The dam has a small size classification and a high hazard potential classification. The owner should institute various remedial measures.

The Lee Pond Dam consists of an earthen embankment with a natural spillway and a vertical stone masonry wall along two short sections of the downstream face. The embankment has a minimum top width of 15 ft. and a maximum height of 25 ft. The overall length of the dam is 870 ft., including the natural spillway at the right end of the dam which is about 15 ft. wide at normal pool elevation. The outlet works consist of an inoperable sluice gate located about 250 ft. from the left end of the dam. The dam impounds Lee Pond, which is used for recreational purposes. Maximum storage capacity at the top of dam is 220 acre-feet. Based on visual inspection and a review of all available pertinent data, the dam is considered to be in poor condition. Features that could effect the structural integrity of the dam are seepage at the downstream toe of the dam, erosion and slumping of dam slopes, extensive tree growth on the dam slopes and animal burrows on the crest and downstream face. The calculated test flood inflow of about 660 cfs results in a routed outflow of about 650 cfs. The spillway passes 100% of the test flood outflow with a freeboard of about 3 ft.

Whiting Pond Dam is approximately 600 ft. long, has a maximum height of 9 ft, and includes a 13-ft. long concrete spillway. The dam is in fair condition, based on a visual examination of the structure. Although some deficiencies were noted, there no evidence of settlement, lateral movement or other signs of structural failure or other conditions which would warrant urgent remedial action. The PMF outflow of 4160 cfs (1015 csm) would overtop the spillway platform by about 2.6 ft. and most of the embankment by 1 to 1.5 ft. With the water at the level of the platform, the spillway (without flashboards) can pass 312 cfs which is 7.5 percent of the test flood.

The dam is L-shaped, about 80 ft. long and 27 ft. high. The dam is in poor condition. The upstream face is overgrown and eroded, the embankment crest deteriorated and abused by improper usage. It falls within the small size category and in the high hazard category. Failure of the dam would cause a flood through a thickly settled area.
