There are several villages in Wu 'an that need to be relocated.

Although the flood control benefit of Li Lou Reservoir is obvious compared with that of irrigation efficiency, there are some resistance problems in the construction. First, the dam site of Li Lou Reservoir is in Yongnian, and most of the reservoir area is in Wu 'an. The reservoir area needs to relocate 13 villages, of which 12 villages are in Wu 'an, with a population of about 30,000 or more, and Wu 'an is not enthusiastic. Second, the reservoir area belongs to the karst water leakage area, with complex geological conditions and high investment in solving the leakage problem. This is the main reason for the delay in the construction of Li Lou Reservoir.

After the completion of the reservoir, controlling the basin area of the upper reaches of the _ River is 22 10 square kilometers, which can effectively intercept the flood in the upper reaches, play the role of peak clipping and disaster reduction, and completely solve the flood control problem in the lower reaches of the _ River, which is of great significance for protecting Yongnian City and Jize County, especially effectively alleviating the flood control pressure of the high-standard flood in Ningjinbo and the flood detention area in mainland China, and realizing the effective irrigation area of 90,000 mu.
