The water level of Xiaolangdi Reservoir is higher in winter and summer. Why?

Generally speaking, the water level of Xiaolangdi Reservoir is higher in summer. The main reasons are as follows:

1. Summer is rainy season, with heavy rainfall, the water quantity will increase. The main functions of Xiaolangdi Reservoir are flood control, irrigation and power generation. Summer rainfall will increase the storage capacity of the reservoir and make its water level rise.

2. In summer, the temperature is high and the evaporation is large. The evaporation of water will reduce the water level of the reservoir, but due to the high temperature in summer, the evaporation will also increase, so the impact on the water level of the reservoir may not be obvious.

3. The inflow of water in the upper reaches of the Yellow River is reduced. Xiaolangdi Reservoir is located on the Yellow River north of Luoyang City, Henan Province. The decrease of inflow in the upper reaches of the Yellow River will also affect the water level of Xiaolangdi Reservoir.

It is worth noting that the water level change of Xiaolangdi Reservoir is influenced by many factors, such as rainfall, evaporation and water coming from the upper reaches of the Yellow River. So the specific situation needs to be judged according to the climate and rainfall of that year.
