High water for the Saratov hydro-electric station this year was shallow. From data of Rosgidrometa, in May the total inflow of water in the storage pools of Volzhsko-kamskogo of cascade was below than norm (60,3 km 3 at a norm a 72,0 km3), and in June expected within the limits of norm. Single breech-blocks by Saratov hydroelectric power PLANT (for the additional upcast of water, besides the hydroelectric generators of the station) were opened from April, 18 for May, 31, I.e. high water for SARGES lasted 44 days (for comparison: in 2008 – more than 50 days; in 2007 – 75 days; in 2006 – 39 days). A peak of high water was
on May, 1, when hardly anymore 26 thousand of m was thrown down3/p. This volume corresponds srednemnogoletnim to the analogical indexes. Thus directly below than weir hydroelectric power PLANT (lower b’ef is the Volgograd storage pool) water rose, as well as in a past maximum, to the mark
21,1 m (on a 6 m higher today’s). Now the charges of water diminished to 7 thousand of m3/sec., with the subsequent diminishing to the norm.Vesnoy 2009 years of the station of Volzhsko-kamskogo of cascade hydroelectric power PLANT OAO «Rusgidro» in accordance with pointing of the Federal agency of water resources provided
dedicaded mode of work of the hydro-electric stations – «rybokhozyaystvennuyu shelf» – from 7 to May, 28. Its duration and volume of water, which in this period is thrown down through gidrosooruzheniya hydroelectric power PLANT, Rosvodresursami is corrected depending on actually accordion hydrological
and aquicultural situation. This mode is annually set, to create a favourable water situation for spawning of fish in nizov’yakh Volga. According to Member of Rule OAO «Rusgidro», leader Biznes-edinicy «Production» Boris Bogusha: «Herein
to the year a situation with water was neprostaya. The winter in greater part of area of vodosbora of Volga was malosnezhnoy, on the prognoses of weather forecasters a mionectic influx was expected. To accumulate water for popuska and for providing of the effective mode of irrigation, Rosvodresursy limited
predpolovodnuyu srabotku hydroelectric power PLANT, and also changed the mode of popuska, moving his beginning against 2008 on 10 days later. A major task on a forthcoming period is filling of storage pools hydroelectric power PLANT Volzhsko-kamskogo of cascade to completion of high water, otherwise
there are risks of shortage of water for a navigation and rural kh
waters in storage pools on Middle Volga expected by near to the norm. In connection with building of regulative storage pools of Volzhsko-kamskogo of cascade natural character of the hydrological mode changed. Maximally to approach him to the natural flow
in lower reaches of Volga, special obvodnitel’nyy popusk is carried out through the nizhnevolzhskie hydro-electric stations. Thus the use for popuska of water, not used up in a winter period, allows in a droughty period to provide the volumes of water for irrigation considerably
greater, than in natural terms, that was impossible to building of Volzhsko-kamskogo of cascade.
