The Three Gorges Reservoir began to release water, gradually making the water level of the Three Gorges reach the flood season level 1.45 meters before the flood, with more rain in the upper reaches of the Yangtze River and more meltwater from glaciers.

After that, water storage will be started at the end of September every year, and the water level of the Three Gorges will gradually reach the non-flood season level of 1.75 meters, and then the water level will be adjusted according to the situation under the Three Gorges dam.
