Emergency spillway definition

Emergency spillway means a spillway designed to safely pass the inflow design flood routed through the reservoir. If the flow is controlled by gates, it is a con- trolled spillway. If the flow is not controlled by gates, it is an uncontrolled spillway.

Emergency spillway means the spillway capable of passing the spillway design storm with the principal and/or auxiliary spillway blocked.

Emergency spillway means a discharge system designed to operate at an elevation above the principal spill way to safely convey discharges that exceed the principal spill way's capacity without jeopardizing the safety of the dam.
