The outlet works consist of concrete conduit through the base of the main dam controlled by two, 2.25-foot square high pressure gates. The capacity of the outlet works is 250 s/f. The spillway is an uncontrolled, concrete lined chute in the left abutment of the auxiliary dike with a capacity of 6,700 s/f. Jenkinson Lake, formed by Sly Park Dam, has a capacity of 41,000 ac/ft with a surface area of 650 acres.
