The dam is an earth dam about 400 ft. long and 16 ft. high. It is small in size with a high hazard potential. Generally, it is in poor condition. Many deficiencies which have been neglected for years were noted. In the event of failure of the dam there is an extent of downstream development that would be seriously affected.

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 impounding structure at West Pond is a 123-foot long, 12-foot high earthfill dam with an overflow spillway at the east abutment. The spillway is located at the east abutment of the dam and consists of a notched ungated concrete weir with an overall length of 16 feet. The low point on the top of the dam is lower than the unnotched portion of the spillway. Based on the visual inspection of the site and a review of the limited data available on the dam, the dam is considered to be in poor condition and is in need of extensive repair work. The following deficiencies were observed at the site: moderate seepage below the toe of the dam; severe erosion of the upstream slope exposing the core wall; erosion of the top and downstream slope of the dam, localized buldging along the downstream slope; lack of a low level outlet; separation of the training walls from the spillway; seepage around and beneath the spillway; brush, timber, and debris in the discharge channel; and trees and vegetation growing on the slopes of the dam. The peak test flood outflow of 107 cfs will overtop the dam by a maximum of 1.3 feet. The spillway can discharge only 1.1 percent of the test flood before the dam is overtopped.

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.

The Parker Mills Pond Dam, Wareham, Mass., is an earthen embankment with vertical, cut-stone masonry walls upstream and downstream, 3/4 of the crest is a bituminous concrete roadway. The embankment has a minimum top width of approximately 10 feet and a maximum height of 19 feet. The overall length of the dam is approximately 400 feet including two spillways. The dam is considered to be in fair condition. A test flood equal to 1/2 the PMF was selected.

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.

The impounding structure at Fountain Pond is a 400-ft long, 16-ft high earth dam with a stone masonry wall on the downstream slope and an outlet conduit. There are deficiencies which must be corrected to assure the continued performance of this dam. The dam is in poor condition. The dam is small in size and has a significant hazard potential. There are various remedial measures that the owner should hire a professional engineer for.
