National Program for Inspection of Non-Federal Dams. Shuttle Meadow Reservoir Dam (CT 00162), Connecticut River Basin, New Britain-Southington, Connecticut. Phase I Inspection Report
The 560 - foot long dam consists of an approximately 38 foot high earth embankment and concrete coping with a concrete corewall along the axis of the dam. The total height from the corewall foundation to the top of the concrete coping is 51.3 feet. Upstream and downstream slopes are inclined to 2 horizontal to 1 vertical and 1.8 horizontal to 1 vertical, respectively. A concrete and brick gatehouse in the reservoir serves as an intake structure for a 30 inch cast iron supply main which runs under the dam to a downstream pump station. The spillway is actually a concrete weir in a relatively flat, 7.5 foot deep, vertical-sided stone masonry channel. However, there are 4 foot high wooden stoplogs presently acting as a weir in the channel. Based upon the visual inspection at the site and past performance, the dam is judged to be in good condition. No evidence of instability of the embankment or appurtenant structures was observed. There are areas requiring attention. Peak inflow to the reservoir is 4300 cfs; peak outflow (Test Flood) is 1400 cfs with the dam overtopped 0.6 feet. The spillway capacity with the stoplogs in place, based upon our hydraulics computations, is 670 cfs, which is equivalent to 48 percent of the routed Test Flood Outflow.
