Also known as “Service Spillways” according to the United States Bureau of Reclamation: “A service spillway provides continuous, or frequent regulated, or staged releases (controlled) or unregulated (uncontrolled) releases from a reservoir without significant damage to the dam, dike, or appurtenant structures due to releases up to and including the maximum design discharge. Service spillways are typically very robust, erosion-resistant structures consisting of mostly cast-in-place reinforced concrete and riprap channel protection”.[1]
