The East Brass Mill Dam, also known as Scovill dam, consists of an earth embankment with a maximum height of 25 feet, a top width of approximately 15 feet, an upstream slope of 2 horizontal to 1 vertical and a downstream slope of 1.7 horizontal to 1 vertical. The dam is 420 feet long, including a 101 foot concrete ogee spillway section located near the left end of the dam. The freeboard from the spillway crest to the top of the left embankment is 5.4 feet. Flashboards, 1.6 feet in height are normally in place, reducing the freeboard to 3.8 feet. The outlet works located to the right of the spillway consist of a control tower or gate house with a high and low. Level inlet which discharges through two 24-inch outlet sluice gates to a 2-Ft.-3- in high by 4-Ft. wide sluiceway that outlet to the downstream face of the spillway. The spillway has a capacity of 4,000 cfs without flashboards and 1,900 cfs with flashboards before overtopping the low point of the dam crest. With the flashboards in place the spillway can pass 11 percent of the Test Flood. Without flashboards the spillway can pass 24 percent of the Test Flood. Without the flashboards in place, the Test Flood would overtop the low point of the dam crest by 3.6 feet.
