Book Description
The dam at Barnes Reservoir is an earth embankment approximately 1,200 feet long, 28 feet high with an average crest width of 15 feet. An uncontrolled stone masonry spillway is constructed integrally with the embankment and its discharges flow through a curved converging chute to the stream below the dam. The outlet works and control tower are located near the left abutment of the dam and discharges from the tower's wet well flow through a 24-inch diameter conduit beneath the dam. As a result of the visual inspection and the review of limited available data regarding this facility, the dam is considered to be in FAIR condition. To assure the long-term performance of this structure, several items of concern require attention: The apparent seepage beneath the spillway slab, a localized depression area in the crest of the dike, the extensive overgrowth of the embankments, spillway and downstream channel, and the inoperability of the upper intake gate to the control tower. The maximum outflow capacity of the spillway under a stillwater condition is equal to 1,200 CFS which represents more than 100 percent of the test flood. However, this discharge will produce a water surface level in the reservoir that has a freeboard allowance of only 1.2 feet below the top of the dam.

Book Description
Stony Brook Reservoir Dam consists of two earthfill embankments with concrete core walls, separated by a 650 ft. long natural promontory. A concrete spillway, 35 ft. wide, is located in the Side Dam. The spillway discharges into a stone masonry channel about 220 ft. long. A gate house located upstream from the Main Dam houses controls for the inlet to a 24 in. dia. water supply line and a 24 in. dia. low level outlet. The dam and appurtenant works are judged to be in generally fair condition. Brush was growing on the downstream slopes of both dams and in the spillway discharge channel. The gate house is in need of repair and the condition of the outlet gate could not be verified. Seeps were found downstream of both dams and cavities were found in the slopes of both embankments. The routed test flood outflow of 5,200 cfs overtops the crest of the Main Dam by 1.3 ft. and the Side Dam by 0.6 ft. The spillway can pass 1,250 cfs or about 24 percent of the routed test flood outflow without overtopping the Main Dam.
