National Program for Inspection of Non-Federal Dams. Middle Pond Dam (CT 00283), Farmington River Basin, Plymouth, Connecticut. Phase I Inspection Report
The Middle Pond Dam consists of an earth embankment and stone masonry structure with a maximum height of 10 feet a top width of 10 feet and a total length of 535 feet including overflow spillways of 21 feet and 29 feet located near the left end of the dam. A low earthen dike with a maximum height of about 3 feet, a top width of about 5 feet and a length of about 200 feet is located about 150 feet to the left of the dam. Based on the visual inspection, the dam is judged to be in very poor condition. Features that could affect the future integrity of the dam are continued erosion of the upstream slope and crest, trees and stumps on the slopes, seepage through the dam, decreased spillway capacity due to blocking off the right spillway, deterioration of the right spillway, and lack of an operable outlet works. With the right spillway blocked the total spillway capacity of 430 cfs is equal to 17 percent of the Test Flood outflow. With the right spillway restored, the total spillway capacity of 550 cfs would be equal to 22 percent of the Test Flood outflow.
