It is not a natural lake, but a reservoir built under Xuedou Mountain in the 1980s. Miaogaotai is a better viewing point. You can't see the dam here, you can only see the mountains around the green lake and the road by the lake. On holidays, this small platform is always crowded with people. Unfortunately, there is no place to see the pavilion down lake and one of its sources Qianzhangyan waterfalls at the same time, otherwise it must be very shocking.
