Water diversion project from Changjiang River to Taihu Lake was carried out right away to ensure water storage and storage capacity of Taihu Lake and meet water demand of lower areas.
The geologic setting of the Changchun City Yanming Lake mineral spring, its forming mechanism, water storage, and water quality are introduced in this paper.
High-danger dammed lake, with great storage capability and high drop height, is often burst in several days to several years after its formation, and causes severe secondary flood disaster.
