Hadahe reservoir

During the occupation of Northeast China, the Japanese puppet government started to build the reservoir at the dam site of the present reservoir in 1943, which was called "bapukang reservoir" at that time. When the "September 3" Anti Japanese war was won, the earth dam was built as high as 1.5 meters. The reservoir has not been built, but many poor Chinese people who were arrested to repair the reservoir died. So far, piles of white bones are still left in Dongshan tomb on the right side downstream of the dam site. During the period of water conservancy in 1958, the three communes of Mishan County, hada, Donghai and Xinglong, with the help of the County Water Conservancy Bureau in survey and design, dispatched 900 people and 100 carriages to carry out design and construction at the same time. In September 1959, due to the decision of Mishan county Party committee to concentrate on the construction of the Balingshan reservoir, the construction of the reservoir was suspended because the migrant workers who participated in the construction of the hadahe reservoir were transferred away. 163000 cubic meters of earthwork was completed, with an investment of 331500 yuan.

Hadahe reservoir

Hadahe reservoir is located in Xinhua Township in the north of Jidong County, in the middle reaches of hada River, a tributary on the left bank of Muling River, 25 kilometers away from Jidong county. Named after the river, the reservoir controls a drainage area of 282 square kilometers with a total storage capacity of 88.6 million cubic meters. It is a comprehensive utilization reservoir mainly for flood control and irrigation combined with fish culture. The project consists of dam, spillway and water conveyance tunnel. (1) The dam is a clay core inclined wall dam with a total length of 470 meters, a maximum height of 21 meters and a crest width of 5 meters. The upstream slope is dry masonry revetment, the slope ratio above the raceway is 1:2.75, the slope ratio below the raceway is 1:3, and the raceway width is 3.5m; the downstream slope is gravel revetment, the slope ratio above the raceway is 1:1.98, the slope ratio below the raceway is 1:2.25, the raceway width is 10.25m, and the raceway width is 6m. The drainage form behind the slope is rock fill prism. (2) The spillway is located at the left end of the dam, which is an open type with a net width of 10 meters. The spillway is 260 meters long, the concrete pouring section is 160 meters long, the overflow weir is 20 meters long, and the maximum overflow is 115 m3 / s. (3) The water conveyance tunnel is located at the right end of the dam. It is a square tunnel with no pressure of 2 × 2.5 meters, with a total length of 99.5 meters. The intake tower is equipped with three layers of gates, with a section of 1.5 × 1.8 meters for each hole, and the maximum discharge is 10 cubic meters per second.

Reservoir construction

During the occupation of Northeast China, the Japanese puppet government started to build the reservoir at the dam site of the present reservoir in 1943, which was called "bapukang reservoir" at that time. When the "September 3" Anti Japanese war was won, the earth dam was built as high as 1.5 meters. The reservoir has not been built, but many poor Chinese people who were arrested to repair the reservoir died. So far, piles of white bones are still left in Dongshan tomb on the right side downstream of the dam site. During the period of water conservancy in 1958, the three communes of Mishan County, hada, Donghai and Xinglong, with the help of the County Water Conservancy Bureau in survey and design, dispatched 900 people and 100 carriages to carry out design and construction at the same time. In September 1959, due to the decision of Mishan county Party committee to concentrate on the construction of the Balingshan reservoir, the construction of the reservoir was suspended because the migrant workers who participated in the construction of the hadahe reservoir were transferred away. 163000 cubic meters of earthwork was completed, with an investment of 331500 yuan.

Jidong county was established in 1965, and the hadahe reservoir area was under the jurisdiction of Jidong county. In May 1967, four communes in Jidong County, including Donghai, Yong'an, Xinhua and hada, dispatched 800 migrant workers to continue the hada reservoir project. At that time, during the period of the "Cultural Revolution", the "Heilongjiang Provincial Revolutionary Committee" was established. The people's Daily published an editorial with the title of "new dawn in Northeast China". The local "rebels", that is, "keep up with the situation", renamed the reservoir "new dawn" and the construction team "new dawn reservoir people's corps".

The continued construction project was jointly designed by Mudanjiang Water Conservancy Bureau and Jidong County Water Conservancy branch. The second geological team of Provincial Water Conservancy Survey and Design Institute drilled the geology of the reservoir area and provided geological data. The Third Engineering Office of Provincial Water Conservancy Department participated in the construction of spillway and water conveyance tunnel. In November 1971, the main project of the reservoir was completed, with 655000 cubic meters of earthwork, 335000 cubic meters of stonework and 73000 cubic meters of concrete, with an investment of 5.55 million yuan. In May 1973, the Provincial Water Conservancy Bureau, the Provincial Water Conservancy Survey and Design Institute, Mudanjiang Water Conservancy Bureau, Jidong County Revolutionary Committee and other units jointly formed an acceptance working group to carry out the inspection and acceptance. In March 1981, the original name of the reservoir, hadahe reservoir, was restored. After the acceptance, in 1982, 70 square meters of block stone revetment was renovated at the subsidence part of the upstream slope of the earth dam, and 2600 cubic meters of gravel was paved and filled at the downstream slope.

Reservoir benefit

The reservoir is designed with an open seasonal power station, which is located 14 meters away from the tunnel exit, with an installed capacity of 65 kW. The project started in the autumn of 1972, completed the hydraulic part and a 42 square meter brick structure plant in June 1973, and installed the unit in September 1974. Due to the failure of motor components and unstable frequency, the unit failed to operate and has been abandoned since then. In 1984, when the water conveyance tunnel was rebuilt from non pressure to pressure, the power station was demolished because of the stilling basin.

During the continuous drought period from 1975 to 1977, hadahe reservoir supplied water in time to ensure the irrigation water for the downstream paddy fields. According to the statistics from 1971 to 1985, the average annual supply of Muling River is 7.5 million cubic meters. In the hada River Basin, 7500 mu of farmland abandoned due to waterlogging has been restored after removing the threat, and 3000 mu of newly reclaimed wasteland has been reclaimed. Since 1971, 15.83 million fry have been put into the reservoir. By 1985, 274000 kg of commercial fish have been caught. There are 15000 mu of suitable forest area in the reservoir area, and 4340 mu of larch, Korean pine and poplar have been planted, with 150000 trees.

Hadahe Reservoir Scenic Spot

Hadahe Reservoir Scenic Spot in Jidong county is located at the junction of hada Township, Xinhua Township and Xingnong Township in the north of Jidong County, 30 kilometers away from Jidong county and Jixi City Center. With a construction area of 2 square kilometers, a water surface area of 10 square kilometers, and a green space area of 17 square kilometers, the scenic area takes the reservoir as the main body and the mountains as the background, forming a lake and mountain scenic area with colorful natural landscape and cultural landscape of blue sky, white clouds, green mountains and clear water. Hadahe reservoir, built in November 1971, is a medium-sized reservoir mainly for farmland irrigation combined with comprehensive utilization of flood control and fish culture. Its storage capacity is 94.6 million cubic meters. Hadahe Reservoir Scenic Spot belongs to hadahe Reservoir Management Committee.
