Drain the lake refers to a lake whose water is connected with rivers and finally flows into the sea.Outflow riverAlong the main rivers and tributaries of the Yangtze River, the climate is relatively mild and humid, the precipitation is rich, and the river supply is mainly rainwater. In addition, the river water volume is abundant, so the lake water level is obviously affected byriver regime Generally, the annual change process of the two is closely consistent.[1]

Introduction
The lake is connected with the river and finally flows into the ocean
A lake whose water connects with rivers and finally flows into the ocean.Along the main and tributaries of the outflow river, the climate is relatively mild and humid, the precipitation is rich, and the river supply is mainly rain. In addition, the river water volume is abundant, which has a large amount of supply to lakes. The lake water level is obviously controlled by the river water regime, and the change process of the two is usually closely consistent within the year.The water balance of the outflow lake is characterized by: the supply part is mainly from the inflow runoff, the loss part is mainly from the outflow runoff, and the proportion of precipitation, evaporation and leakage on the lake surface is small.The lake has an obvious regulating effect on the river runoff, making the water level of the downstream river change relatively gently, and the flood peak lags behind.[2]
