===River management===
In 2007, the [[World Bank]] lent US$1 billion to aid [[river treatment]] in Xining, including [[Sanxian County]]'s anti-[[flooding]] project, with an added US$1 billion to support infrastructure. Qinghai has invested large amounts in the treatment of Huangshui Main River and Nanchuan River, totalling {{convert|24.5|km|abbr=on}}. However, a treatment on a {{convert|40|km|abbr=on}} river course and 10 flash flood relief channels remain pending due to lack of equipment. In Sanxian County, a {{convert|108.4|m|abbr=on}} long river course and 80 flash flood relief channels need treatment.
