Basic scheme

Water–sediment conditions in 1961–1970

The reservoir operated with the water level in front of the dam being 135–139 m from June 2003 to June 2006; the reservoir operated with the water level in front of the dam being 144–156 m from September 2006 to September 2008; the reservoir operated with the water level in front of the dam being 175–145–155 m from October 2008 to June 2602
