National Dam Inspection Program. Mianus Reservoir Dam (CT 00050). Connecticut Western Coastal Area, Stamford, Connecticut. Phase I Inspection Report.
Abstract
The Mianus Reservoir Dam consists of an earth embankment with a selected impervious fill core, drop inlet spillway, stilling basin, a wasteway having a fuse plug and pumping facilities. Based on the visual inspection, records available, and past operational performance, the dam is judged to be in good condition. The project will not pass the test flood without overtopping the dam, and therefore, the total spillway capacity is inadequate. The spillway capacity is judged seriously inadequate since the project will not pass one-half the test flood without overtopping the dam (35 percent). The test flood will overtop the dam by approximately 2.9 feet. It is recommended that the owner ensure that the materials contained in the fuse plug are excavated and replaced, without tamping. Additionally, the scour hole at the spillway should be repaired. The owner should control trespassing on the dam, particularly near the junction of the left abutment and the downstream slope where trespassing is extensive at the present time.
