Eco-environmental Impact of Dayuan Watari Wataru Power Hub

The completion of Dayuan Watari Wataru Power Hub has also affected the ecological environment, such as the reproduction of migratory fish. Anchovies, swordfish, mullet and shad are all migratory fish, and they like to feed and lay eggs in the shoals with stable water flow in Xiangjiang River. These migratory fish lay eggs in shallow water weeds along the river from the downstream, and after hatching, the young fish grow to a certain extent and then go downstream. The completion of navigation and power hub has made these migratory fish lose their "natural living environment". Therefore, in order to protect migratory fish, managers raise fish fry in the upper reaches every year to ensure the reproduction of migratory fish.

At the bottom of Dayuan Watari Wataru Power Hub, Xiangjiang River also sucks water to join. Dayuandu reservoir area is affected by water storage. The water level at the confluence is not high and the water flow is slow, but the water quality is clear. In the middle of the river, a large sandbar stands out. Looking up from here, the highway bridge at the top of the dam of Dayuan Watari Wataru Power Hub, "a bridge flying north and south", stands proudly on the Xiangjiang River and is magnificent.
