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”.<ref name="DS14">[[Design Standards No. 14: Appurtenant Structures for Dams (Ch. 3: General Spillway Design Considerations) | Design Standards No. 14: Appurtenant Structures for Dams (Ch. 3: General Spillway Design Considerations), USBR, 2014]]</ref>

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]

In many cases, these spillways include closed conduits and function as both a service spillway and outlet works.
