The bottom of Sun Moon Lake is dry and uneven. What is the reason?

Recently, the drought crisis in Sun Moon Lake, a famous scenic spot in Taiwan Province Province, caused a heated discussion on the Internet. It can be seen from the recent photos of Sun Moon Lake that there is no water in Sun Moon Lake, and the mud at the bottom of the lake has cracked because of too much drought and has dried up into pieces. The beauty of the sun and the moon in the past no longer exists. It stands to reason that Sun Moon Lake, as one of the most representative scenic spots in Taiwan Province Province, should be well maintained. How did it end up like this? What caused it? Let's see why.

There has been too little rainfall recently, and the lake in Sun Moon Lake has dried up. The most direct reason is the recent lack of rainfall in Taiwan Province Province. If there had been enough rainfall, Sun Moon Lake would never have fallen to such a state. In fact, as far as the geographical environment of Taiwan Province Province is concerned, it is located in the southeast coastal area of China. Under the influence of monsoon, rainfall is generally very abundant, far exceeding the world average. Therefore, I haven't heard of the drying up of Sun Moon Lake for many years. I didn't expect extreme weather to occur frequently in recent years, and now even the Sun Moon Lake, which entered the primary school textbooks, has dried up.

Another reason for the lack of topographic water storage capacity is that Sun Moon Lake is too shallow, and there are basically no water storage dams and large water storage lakes in Taiwan Province Province to provide water for Sun Moon Lake. Although Sun Moon Lake is famous in mainland China, it is actually a small lake with an average depth of about 20 meters, less than 8 square kilometers. A small lake like this is naturally prone to water shortage and dryness when it encounters excessively dry weather. Moreover, even if the rainfall is heavy, the Sun Moon Lake is only so deep that it can't effectively store too much rain, so it can only flow to the sea. Over the years, due to the abundant rainfall in Taiwan Province Province, Sun Moon Lake rarely dried up to the bottom. I didn't expect the drought to last a little longer and then it was revealed.

There are few natural lakes in Taiwan Province Province, and Sun Moon Lake is the most famous scenic spot in Taiwan Province Province. Sun Moon Lake is 748 meters above sea level, and the water surface is about 8 square kilometers at ordinary times, and it can reach 10 square kilometers when it is full of water. The circumference of the lake is 38 kilometers, and the deepest part of the water is 27 meters. There is a Guanghua Island in Sun Moon Lake, which divides the whole lake into two halves. The lake in the north is as round as the sun, so it is called Sun Lake. The lake in the south is crescent-shaped, called Moon Lake, and the whole lake is called Sun Moon Lake. It is said that Sun Moon Lake was originally two independent lakes. Later, because the downstream dam was built to generate electricity, the water level rose and the two lakes merged into one, forming the wonders of Sun Moon Lake. Around Sun Moon Lake, there are many ancient pagodas and temples, and the scenery is beautiful. In Xuanzang Temple in the Mid-Levels, there are also some remains of Master Xuanzang, a famous ancient monk in China.
