The project is the largest water conservancy project of the Huaihe River so far, and it is a key project to raise the flood control standard of the middle reaches of the Huaihe River to once in a hundred years. In 2007, the biggest flood occurred on the Huaihe River since 1954. The Linhuaigang project was put into operation in time, and the project operated normally without any danger, which effectively reduced the flood control pressure on the main stream of the Huaihe River and played a huge flood control benefit. The completion of the Linhuai igang project ended the history of no flood control project in the middle reaches of the Huaihe River and realized the long-cherished wish of the people along the Huaihe River and the "century dream" of several generations of people.
