GateBrief description of the gateSeismic resistance rankLikelihood of gate failure

Spillway gateThe gate is located on the left bank and is susceptible to seismic loading and rockfall.3Fairly likely

Flood discharging tunnel gateThe gate is located in the inlet of the flood discharging tunnel and is submerged.2Even

Emptying tunnel gateThe gate is located in the inlet of the emptying tunnel and is submerged deeply in the reservoir.1Unlikely
