When was Changtan Reservoir built?

1963 completion of huangyan changtan reservoir.

In the early days of liberation, the water conservancy foundation in my hometown was very weak, and the dikes and seawalls were in tatters. The water storage capacity of river ponds is only 49 million cubic meters, the average drought resistance of paddy fields is 19 days, the power of mechanical water lifting is only 48 horsepower, and the irrigation area is only 0.190,000 mu.

Over the past 50 years since the founding of the People's Republic of China, Huangyan has continuously consolidated the labor accumulation system, reformed the water conservancy investment system, and gradually established a multi-level and multi-channel water conservancy investment mechanism. Large-scale mass capital construction of farmland water conservancy is getting better every year. Lingxiu Reservoir was built in 1957, Changtan Reservoir was built in 1963, followed by Foling Reservoir and Shierkeng Reservoir. Hometown people are proud that Changtan Reservoir, a large-scale water conservancy project built on their own, has a dam height of 43 meters, a maximum water level of 42 meters, a total storage capacity of 690 million cubic meters, a normal water level of 36 meters, a corresponding storage capacity of 457 million cubic meters, and an irrigation area of 1.05 million mu, ranking first in the province. The total installed capacity of Changtan Reservoir Hydropower Station is 9920 tons. The completion of Changtan Reservoir has fundamentally improved the water conservancy conditions of farmland over 1 10,000 mu in Huangwen, Wenjiao, and Xicen, Linhai (the average drought resistance has increased from 40 days to 70 days, and most farmland can achieve drought and flood protection). At the same time, it provides electricity for irrigation areas and domestic water for industry and residents, and the social benefits are becoming increasingly significant. 1995 10 huangjiaowen water diversion project (Phase I) has become the main drinking water source for residents in three districts and one city (Huangyan, Jiaojiang, Luqiao and Wenling). 199365438+February, the first phase of Yongning River Regulation Project started, which took five years to complete, and played a great role in promoting the economic and social development of Huangwen Plain.
