Mount Higby Reservoir Dam is an earthfill embankment about 865 ft. long, with a maximum height of about 30 ft. The spillway channel is located at the left abutment and appears to be excavated in bedrock. A wet well outlet structure is connected to a water treatment plant below the dam by means of a buried 20 in. dia. service main. There is also a 36 in. dia. blowoff pipe with an outlet into a natural channel below the dam. Mount Higby Reservoir is utilized as a water storage facility for the City of Middletown. It is about 6,000 ft. long and has a surface at normal storage of 134 acres. The drainage area is 1.44 sq. mi. and the maximum storage to the top of the dam is 1,750 acre-ft. The test flood inflow is 3,500 cfs., while the outflow is 1,160 cfs. at a surcharge elevation of 366.5, about 0.3 ft. below the top of the dam. The spillway is therefore adequate to pass the test flood outflow without overtopping the dam. The dam is judged to be in generally good condition. Flows of undetermined origin, which may be seepage from the reservoir, appear in the downstream channel and cause two marshy areas below the dam. The dam and appurtenant structures appear to be well maintained, but there is some brush growth and several mature trees on the downstream side of the access road berm.

The project, substantially reconstructed in 1967, has a total length of approximately 320 feet, consisting of an approximately 300 foot long embankment and a 20 foot long concrete spillway. The dam is approximately 23.5 feet in height above the streambed of Long Hill Brook and, with the pond level to the top of the dam, impounds approximately 250 acre-feet of water. The upstream slope is protected to the top of the dam by dumped rock riprap. The spillway is a concrete chute and is located near the right end of the dam. The low-level outlet facility is a 24 inch reinforced concrete pipe at the central portion of the embankment and is controlled from a concrete gatehouse on the dam. Based upon visual inspection and past performance, the project is judged to be in fair condition. No evidence of instability of the embankment or spillway was observed. However, there are items which require monitoring and/or maintenance, such as erosion of the spillway discharge channel and a stagnant water condition in the low-level outlet channel which does not allow a free flow of water from the toe drain pipes. Peak inflow to the reservoir at the 1/2 PMF is 850 cubic feet per second (cfs); peak outflow is 580 cfs with the lowest point along the top of the dam overtopped by 0.4 feet. The spillway capacity, with the reservoir level to the low point of the top of the dam, is 380 cfs, which is equivalent to 66% of the routed test flood outflow.
