|
| 13. | Water from the power station is discharged down a long tailrace tunnel to the lower reservoir.
|

|
| 15. | The canal passes under the unique Tokaanu Tailrace Bridge, a combined road bridge and aqueduct.
|
| 16. | Parallel to the powerhouse, a tailrace tunnel discharges the water to the river channel below.
|

|
| 18. | The tailrace of the power plant discharges directly to the reservoir of the Qingshan Dam downstream.
|
| 19. | After power generation the water will be discharged into the lower reservoir via four tailrace tunnels.
