Abstract:

The Laurel Reservoir Dam is a linear concrete gravity structure, 1,950 feet long with a 100 foot spillway located on the west end of the dam. An earthen embankment on the downstream portion of the dam begins 10 feet below the top of the dam, having a 10 foot wide top width and a 21 horizontal to vertical slope. Based on a visual inspection of the site, review of available information and past performance of the dam, the dam is judged to be in good condition. The maximum spillway capacity at top of dam is 15 per cent of the peak inflow rate of the test flood. Therefore, the test flood cannot be passed by the spillway without overtopping the dam. The overflow will be 2.6 feet above the top of the dam.
