National Program for Inspection of Non-Federal Dams. Merimere Reservoir Dam (CT 00252), Mattabasset River Basin, Meriden/Berlin, Connecticut. Phase I Inspection Report

摘要

The Merimere Reservoir Dam is an earth dam that is approximately 690 feet long and 30 feet high. It also has an emergency spillway. Based on visual inspection, records available at the site and past operational performance, the dam is judged to be in poor condition. A review of the limited engineering data available reveals that there are areas of concern. The downstream side of the dam shows signs of fairly heavy seepage and as a result, it is felt that this condition should be investigated further. The project spillway will pass only 12 percent of the estimated Probable Maximum Flood (PMF), the recommended spillway test flood. Therefore, further hydrologic and hydraulic studies are recommended to refine the test flood, determine the ability of the dam to withstand overtopping, and, if appropriate, recommend measures to increase the hydraulic capacity of the spillway.
