The reservoir was created by the dam of Zhiguli Hydroelectric Station (formerly, V.I. Lenin Volga Hydroelectric Station), located between the cities of Zhigulevsk and Tolyatti in Samara Oblast. It was filled in 1955–1957.[citation needed]

With the filling of the reservoir in the 1950s, some villages and towns were submerged by the rising water and were rebuilt on higher ground. These included the old fortress town of Stavropol-on-Volga, which was replaced by Tolyatti. One district of Ulyanovsk is below water level and is protected from the reservoir by an embankment.[citation needed] It is now one of the most successful reserviour projects in Russia.
