The dam can hold a water storage capacity of 8.5 million stere and spectacular waterfall sight will be formed flowing from the side holes of the dam when the reservoir is swollen. On both sides of the dam lays two tunnels, the one in the south is around 300 meters long and connects the outer world directly, the 100-meter-long one in the north leads to the north slipway.
