Xianghai Reservoir is a plain river reservoir, and it is a large-scale (II) reservoir that makes full use of the flood resources of Taoer River, Huolin River and Emute River, provides water environment for Xianghai National Nature Reserve, supplies water to reed fields and wetlands, and raises fish. The main water sources come from the flood diversion flood of Taoer River and the south branch flood of Emute River. 1993 put forward a water diversion project, that is, the flood of Huolin River is diverted to Xianghai Reservoir, which not only meets the flood control needs of Huolin River basin, but also makes water supply to Xianghai Reservoir, thus bringing the reservoir benefits into play. In 2003, some water diversion projects were completed. Xianghai Reservoir controls 548 square kilometers of the Emute River Basin.
Tuanjie Reservoir is located in Xialing Town, Taobei District, Baicheng City, Jilin Province. Its head is in Yinggen Tun, Hada Nala, Keyouqian Banner, Inner Mongolia.

Wujianfang Reservoir is located in Liuhe Township and Chagan Town, Da 'an City. It is a medium-sized reservoir on the right side of the lower reaches of Taoer River, next to Tao Xin and Xingfu Main Canal. The control basin covers an area of 37 square kilometers and belongs to the plain reservoir. The reservoir was built in 1975, and it began to store water in the autumn of 76. It is mainly used for flood storage, irrigation, water supply (marsh water), fish farming, tourism and wetland protection. In 2003, it was identified as a third-class dangerous building by the expert group, and the reinforcement project was carried out. The main works of the reservoir include: 3 1 earth dam, long 12km, 2 intake sluices, 1 control sluices and 3 discharge sluices. The reservoir is designed according to the 20-year return flood, and checked by 100 return flood. The total storage capacity of the reservoir is 30.53 million cubic meters, and the check flood level is 142.65 meters; The designed dead water level of the reservoir is 14 1.0m, with a storage capacity of 7.75 million cubic meters.
Qunchang Reservoir, located in Jinna Town, taonan city, is a medium-sized reservoir with comprehensive utilization of flood control, waterlogging elimination, irrigation and fish farming. There are three tributaries of Meiyao River, Gushu River and Shuangfa River in the upper reaches, with a drainage area of 1360 square kilometers. Because this basin is a typical rainstorm center in the whole province, it has the remarkable characteristics of concentrated rainfall, fast runoff production, short confluence time, high peak value and large flood volume, and the flood control task is very arduous. Qunchang Reservoir1972 started construction in September, and1974 closed the reservoir in July and began to store water. 1992 expansion of emergency spillway,1completed in June 1993. The original design flood standard of the reservoir is once every 50 years, and the check standard is once every 500 years.

The total length of the dam is 3 100 m, the crest width is 4 m, and the crest elevation is 248.00 m. Emergency spillway and normal spillway undertake the task of reservoir flood regulation, and the maximum flood discharge is 1 120s cubic meter and 520s cubic meter respectively. Water conveyance tunnel and irrigation tunnel are mainly used for emptying storage capacity and regulating irrigation water. Because the reservoir basin is located in the mid-mountain area and the vegetation condition is poor, the reservoir siltation is aggravated year by year. In 200 1 year, the measured total siltation is 2 1.92 million cubic meters, which greatly reduces the flood control capacity of the reservoir.
Chuangye Reservoir is located in Cheli Township, about 35km west of taonan city. It is not only a river blocking reservoir on the Emute River, but also a branch reservoir downstream of the main canal of Taohe River. Belonging to the Songhua River Basin, with the accumulated rainfall area of 183 1 km2, it is a medium-sized plain reservoir integrating flood control, irrigation and aquaculture.
