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.

It is an earthfill structure with a concrete core that is about 1390 ft. long having a maximum height of 60 ft. The dam is fair condition, there being several motorbike trails and footpaths on the downstream slope. It is intermediate in size and has a hazard potential of high. Failure of the dam would inundate the baseball field and recreational area immediately below the dam and would pass through a thickly settled residential area. Additional investigations or major modifications are not required.

The dam consists of an earth embankment approximately 630 ft. long and 40 ft. high with an ungated spillway about 40 ft. long at the center of the structure. The only outlet is a 24-in. pipe from a gate house intake located in the upstream slope. Based on a visual examination of the structure, the earth embankment and spillway are in good to fair condition. There was no evidence of settlement, lateral movement or other signs of structural failure or other conditions which would warrant urgent remedial treatment. The spillway has a capacity of 1790 cfs with flashboards removed and can pass the PMF outflow of 1530 cfs (750 csm) with the water level 0.6 ft. below the top of the concrete core wall.
