Basic Information
The reservoir was formed in 1965 - 67 years. dam Vilyui hydropower plant on the river Vilyui . When the reservoir was created, 2.3 thousand hectares of farmland were flooded and 50 buildings were relocated. [one]
The area of the reservoir at a height of 246 m above sea level is 2,360 km² . According to the hydropower plant project, it is permissible to raise the level to a forced retaining level of 249 m and operate it to 231 m, which corresponds to a maximum amplitude of 18 m. [1] Significant changes in the water level are caused primarily by the uneven precipitation in different years.
The average long-term inflow of water is 20 km³ per year. The total volume of the reservoir at NPU is 40.4 km³, including the useful one - 22.4 km³. [one]
Economic Significance
The reservoir is used for seasonal and multi-year regulation of Vilyuya runoff, as well as for water supply, shipping and fishing. Fish live here - nelma , chir , etc. [3] [4] The passes from the reservoir through the spillway of a hydroelectric power station are used to provide navigation conditions in the lower reaches of the Vilyui River.
