Ranks of seismic resistance of gate and linguistic descriptions of the likelihood of gate failure.
| Gate | Brief description of the gate | Seismic resistance rank | Likelihood of gate failure |
| Spillway gate | The gate is located on the left bank and is susceptible to seismic loading and rockfall. | 3 | Fairly likely |
| Flood discharging tunnel gate | The gate is located in the inlet of the flood discharging tunnel and is submerged. | 2 | Even |
| Emptying tunnel gate | The gate is located in the inlet of the emptying tunnel and is submerged deeply in the reservoir. | 1 | Unlikely |
