The Dragon Lake is located in the downstrean of Fu River. It is not far away Saigen Pond, named after its shape. In 1958, it is built a dam of 50m high and 80m long in the gate of Dragon Lake. Now is Fu River Reservoir.

Because of that, the area of the Dragon Lake is expanded. The length of the lake is more than 5km, but its width is different that the widest one is nearly 1,000m. The depth of the lake is also different that the deepest one is more than 40m. The water capacity of the lake is more than 2000 cubic meters, and electricity is 5000kw each hour.

The building of the reservoir is not only convenience to the rural people, but increasing infinite scenes.
