Channel 1500m, in which the cement stone grouting dam is 500m, the channel width is 2 ~ 3m, and the effective irrigation area is 400 mu.

The main mineral resources are limestone, which is distributed in Shizikou, Qian Dian Village and Xiahe Low Mountain, Central Village. There are a lot of limestone in Xueluo Formation in Li 'ao Village and Bamaogou in Sanxing Village.
