“An emergency spillway is designed to provide additional protection against overtopping of a dam and/or dike and is intended for use under unusual or extreme conditions such as misoperation or malfunction of the service spillway or outlet works during very large, remote floods (such as the PMF), or other emergency conditions. As with auxiliary spillways, some degree of structural damage and/or erosion may be expected due to releases up to and including the maximum design discharge”.<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> | “An emergency spillway is designed to provide additional protection against overtopping of a dam and/or dike and is intended for use under unusual or extreme conditions such as misoperation or malfunction of the service spillway or outlet works during very large, remote floods (such as the PMF), or other emergency conditions.
