National Program for Inspection of Non-Federal Dams. Nepaug Dam (CT 00370), Farmington River Basin, New Hartford, Connecticut. Phelps Brook Dam (CT 00378), Farmington River Basin, Burlington, Connecticut. Phase I Inspection Report

摘要

The Nepaug Dam is a semi-arch gravity type dam with a spillway. It is 6500 feet long and 113 feet high. The Phelps Brook Dam is an earth dam with a concrete core wall. It is 1,250 feet and 67 feet respectively. Both of these dams are located at opposite ends of the Nepaug Reservoir. The Phelps Brook Dam has no overflow. The project will pass the Probable Maximum Flood (recommended Spillway Design Flood) without overtopping the dam. The general condition of both dams and appurtenant structures is good. Some recommended measures to be undertaken by the owner include monitoring movements of parapet walls at the upper gate house of the Phelps Brook Dam, monitoring seepage at both dams and vibrations at the Nepaug Dam during periods of heavy flow.
