Where is the Iron Mountain Reservoir How deep is the water in the Iron Mountain Reservoir

The Tieshan Reservoir is located at the mouth of the Tieshan Gorge and in the Gongtian District of Yueyang County, which flows directly into the middle reaches of the Shagang River, a tributary of the Xinqiang River, which directly flows into the East Dongting Lake. The rainfall collection area is 465 square kilometers, and the water area of Xiaoraogang Reservoir is 28 square kilometers, totaling 493 square kilometers. The average flow of the dam site for many years is cubic meters per second, the total runoff is 100 million cubic meters, and the reservoir capacity coefficient is a multi-year regulating reservoir.

The project consists of a dam, a spillway, a diversion and venting tunnel, a secondary dam, a Xiaomei connecting tunnel, a diversion tunnel for the north-south trunk canal, and a hydropower station at the head of the canal. The dam is a clay inclined wall sand-gravel mixed dam, the dam is 211 meters long, the top width is 8 meters, and the dam crest elevation is 96 meters; The spillway is located at the natural pass on the left side of the dam, which is a rectangular section with a wide top weir with an elevation of meters at the top of the weir, and three 10 9 meters steel arc gates are installed, with a flood discharge volume of 1520 cubic meters in 100 years; The diversion and venting tunnel is located in the granite mountain on the right bank of the dam, and the diversion during the construction period is retained, and the reservoir is left as the bottom hole after completion, and the bottom water of the reservoir can be emptied, and the tunnel is full length and the diameter of the tunnel is meters; The 2256-meter-long Xiaomei Tunnel is a connecting tunnel between the Tieshan Reservoir and the Xiaoraogang Reservoir (a medium-sized reservoir that has been built), and its function is that the water of the Tieshan Reservoir is sent to the Xiaoraogang Reservoir through the Xiaomei Tunnel during the irrigation period, and then goes to the Nangan Canal through the Nangan Water Intake Hole to irrigate 10,000 acres of farmland. During the non-irrigation period, the surplus water of Xiaoraogang Reservoir was reversed and the Xiaomei Tunnel was replenished to Tieshan Reservoir; The first diversion tunnel of the south trunk canal passes through the mountain to the right side of the spillway of the Rao Gang Reservoir to the Darao Port, with a total length of 174 meters, the end of the tunnel is connected with a pressure water tank of 5 meters long, 14 meters wide and 14 meters high, and the steel arc door is hoisted with 2 25 tons of hoist, and the diversion flow is controlled, and then divided into two branches, the left branch leads to the irrigation channel through the sluice chamber, and the right branch uses the diversion pipe to pass the power generation plant; The first diversion tunnel of the North Trunk Canal directly takes water from the reservoir and crosses the mountain on the right bank of the dam, with a total length of 220 meters, and is divided into two branches through the fork pipe, the left branch is directly connected to the irrigation channel, and the right branch is connected to the power plant through the reinforced concrete diversion pipe.

The reservoir is mainly used for irrigation, and has comprehensive benefits such as flood control, sand retention, power generation, water supply, aquaculture, shipping in the reservoir and tourism development.

The construction of the pivotal project started for the second time in 1978, and then stopped the construction, and officially resumed work in August 1981, and the reservoir was closed and stored on April 11, 1982, and the dam was filled to the design dam crest elevation of 96 meters at the end of April. The dam is equipped with complete prototype observation instruments and equipment, and systematic observation began during the construction period, and its data were compiled and published. The irrigation area includes Yueyang, Miluo and Linxiang counties, with a total irrigation area of 10,000 mu.

Tieshan Reservoir Tieshan Reservoir is located in the upper reaches of the Xinqiang River in Yueyang City, Hunan Province, also known as "Acacia Lake", and belongs to the Tieshan Scenic Area of Dongting Lake Scenic Area in Yueyanglou, Hunan Province. Its water surface area is 10,000 acres, with a storage capacity of 100 million cubic meters, and it is the largest artificial lake in northern Hunan Province. It has comprehensive benefits such as urban water supply, fish irrigation, flood control, sand retention, power generation, and tourism.

The Iron Mountain Reservoir is scattered in the public field!

Tieshan Reservoir is located 46km southeast of Yueyang City, named after the site of the reservoir dam in Tieshan, and the reservoir dam is a clay inclined wall sand-gravel mixed dam. It is 44m high, 70m long at the bottom, 272m wide, and 10m wide at the top. The rainfall collection area of the reservoir is 493 square kilometers, and the normal water surface is square kilometers.

The total capacity of the library is 100 million cubic meters. The spillway on the left side of the dam is 30m wide, and three arc gates of 10m and 9m are installed, and the flow rate is cubic meters per second, which is sold to make a once-in-a-century flood with a downward flow of 1520 cubic meters per second, and can also ensure the safety of the reservoir. After the completion of the reservoir, the inundation of countless hills, the formation of hundreds of small islands, the elegant and slippery called "the lake of a thousand islands", and the newly developed Ming Dynasty ancient buildings Zhangguying Village, Dayun Mountain National Forest Park into a piece, become a new scenic tourist area in Yueyang City.
