Why should Kunming Huang Shiyan build a reservoir?

Reservoir is one of the flood control measures in China. Building a reservoir at an appropriate position in the upstream of the flood control area can stop the flood and reduce the downstream water flow, thus achieving the purpose of alleviating the flood disaster.
