The water level in the reservoir flooded bed Boguchanskaya hydropower plant on the Angara River rose after the flood of 20 meters, told RIA Novosti on Friday the head of the Yenisei Basin Water Management (which controls operation of the reservoirs on the Yenisei and Angara cascade) Vladimir boon.
"Right now, the water level reached the level of 166 meters, up to the beginning of May it was about 147 meters," — said the blessing.
About that, when the filling of the reservoir, nor of "Boguchanskaya HPP" (been building, and now operates the station) or in the "RusHydro" (co-investor of the project) could not tell. Information on the Completion of the press service of the company promised to later.
High alert for the upcoming filling the reservoir was introduced MES in the Krasnoyarsk Territory is April 19. As RIA Novosti on Friday, the press service of the government of Krasnoyarsk region, according to a hydro operators, content began 10 days after the administration of high alert.
"According to the Regional Ministry of Economy and Regional Development, which oversees the construction of BoHPP, filling of the reservoir began on April 29. As of May 16, the water level rose by 17.7 meters, other data have so far not. Next, apparently filling will go more slowly, as you know, to finalize its plans only in the IV quarter of 2013, when the water level will reach 208 meters, "- said the head of the press service of the governor and government edge Irina Samsonov.
Several other data provided RIA Novosti familiar with the matter Member of the Legislative Assembly of Krasnoyarsk region chairman of the committee on Natural Resources and Ecology, Alexander Simanovsky. According to him, the filling of the reservoir began on April 16, the last bottom opening in the body of the dam was leaking water into the downstream, was closed on May 9.
"According to my information, now the water level in the reservoir broke the mark of 165 meters. Filling will continue on, but May 30 will drain the water through the dam. Recommended amount discharged — two thousand cubic meters per second," — said Simanovsky.
In the Yenisei river basin water management is also information that the beginning of June to slow filling of the reservoir — in order to eliminate the possibility of a dramatic shallowing in the downstream of the dam.
"Navigation in the downstream is not open, but it will start on June 1 in connection with the discharge of the water needed for hydropower is already under way. Top level navigation of the river is within the normal range, no emergency is expected", — the head of the Yenisei Basin Water by Vladimir boon.
As previously reported, the filling of the reservoir BoHPP will be held in two phases to reach 185 meters, and then to the level of 208 meters. When hydroelectric project in the flood zone will get 149.5 thousand hectares of land in the Krasnoyarsk and Irkutsk region.
"On Monday, April 16, closed the third technological bottom opening in the dam. However, the water level in the upper reservoir befe and discharge of water in the bottom befe virtually unchanged. At the station continued technological procedures, fourth and fifth bottom openings remain open," — said interlocutor.
In the body of the dam five technological bottom opening. The first two of these were closed in September 2011.
As RIA Novosti reported earlier, the Ministry of Economy and Regional Development of the Krasnoyarsk Territory considers necessary to carry out the waste water discharge into the downstream Boguchany hydroelectric during filling of the reservoir in the amount of not less than two thousand cubic meters per second. This is the amount of filling the reservoir to minimize the risks associated with the filling of the reservoir.
BoHPP construction began in 1980, and then, after a stop in the early 1990s, reopened in 2006, JSC "RusHydro" and OK "Rusal" after agreement on a joint project to create Boguchansk Energy and Metals Association (BEMO).
