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.

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.
