National Program for Inspection of Non-Federal Dams. Pitch Reservoir Dam (CT 00474), Naugatuck River Basin, Morris, Connecticut. Phase I Inspection Report.
Abstract
Pitch Reservoir Dam is a 920 foot long earth embankment and concrete dam. The earth embankment section is 800 feet long and has a maximum height of 94 feet. The concrete section is 120 feet long with a height of about 40 feet. The spillway is located on the left (east) side of the dam. The top width of the earthen embankment is 20 feet and the concrete section is 12 feet. The visual inspection of Pitch Reservoir Dam indicated that the dam is in good condition and well maintained. The inspection revealed the efflorescence of the joints of the concrete section of the dam existed and an animal burrow was found beneath the tow of this section. Water was observed flowing from a perforated pipe adjacent to the service road in the vicinity of the west embankment. Minor deterioration and slight seepage through joints was observed near the top of the spillway wall. Based on its intermediate size and significant hazard classification in accordance with the Corps guidelines the test flood is equal to the Probable Maximum Flood. The spillway will pass the test flood outflow of 4725 cfs with a pool elevation 731.1 feet which is 4.9 feet below the top of the dam.
