This volcanic lake is 351 meters above sea level, the deepest part is 211.4 meters, and the area is larger than the Akan Lake. Surrounded by cliffs of three or four hundred meters, it is said to be the most transparent lake in the world because it does not flow in and out without impurities. There is often fog on the lake, especially in June and July (see Figure 9). There is an old song called "Mo Zhou Lake in the fog", and there are several legends about the fog of Mo Zhou Lake.
