It is situated in Tatarstan, Udmurtia, Bashkortostan and Perm Krai, Russian Federation.

The reservoir was filled in 1978-81 up to 62 m above sea level after the construction of dam of the Lower Kama Hydroelectric Station.

The Lower Kama Reservoir has a surface area of 1,084 km² and a volume of 2.8 billion cubic meters.

The reservoir also used for water supply, irrigation and fishing.
