National Program for Inspection of Non-Federal Dams. Spring Lake Dam (CT 00261), Connecticut Coastal, Southington, Connecticut. Phase I Inspection Report.
Abstract
Spring Lake Dam is an earthen embankment dam with a reinforced concrete spillway located 60 feet from the left end and a wood/steel sheet cut-off wall running its entire length. The total length of the dam is 200 feet including the 31 foot long spillway. The maximum height of the dam, measured at the left spillway abutment, is 13 feet and the maximum storage capacity with water at the top of the dam is 94 acre-feet. The spillway is a sharp crested weir with three separate discharge bays and training walls. A 12 inch conduit with a slide gate control passes through the right discharge bay. The visual inspection of Spring Lake Dam indicated that the dam is in FAIR condition. The inspection revealed an unprotected upstream face of the dam which could lead to further erosion by wave action and that there are areas of erosion along the spillway training walls. In addition the downstream face of the dam is covered with grass, weeds and brush and there are trees growing along the right abutment of the dam. The spillway, with a peak discharge capability of 1770 cfs, can pass 250% of the design storm without overtopping the dam.
