Abstract:

Prospect Hill Reservoir is impounded by a rectangular, concrete-lined earth embankment. The reservoir, which was built in 1956, measures 604 feet by 274 feet. The embankment is about 1,200 feet long with a maximum height of 25 feet and side slopes at 21 horizontal to vertical. There are two high-level overflow drains and two low-level drains which connect to a single 12-inch outlet conduit. The outlet conduit leads 200 feet downhill to an overflow pond with 1 mil. gal. capacity. The reservoir and embankment are generally in good condition and well maintained. The following deficiencies were observed at the site growth of trees on the slopes of the embankment, slight leakage from some joints on the conduits, an leakage from a gate valve into the outlet conduit. It was also noted that a greater than expected amount of seepage is occuring in the under drain system. Under normal operating conditions, the reservoir cna discharge 100 percent of the test flood without overflowing the rim.
