Design
The dam has a maximum height of 34 m and a length of 4790 m. It is composed of a combined 365 m long concrete power station and 191 m long spillway section which are both flanked by the embankment dam portion. The embankment portion of the dam contains 20899000 m3 of soil and 884400 m3 of rock, drainage and filter placement. The concrete structures of the dam, namely the spillway and power station comprise 1236600 m3.

The power station is 269 m long, 22.5 m wide and 28.3 m high. It contains 10 Kaplan turbine-generators. There are six transformers ranging from 110-500 kV.

Votkinsk Reservoir holds 9400000000 m3 of water of which 3700000000 m3 is active or "useful" capacity. The reservoir's catchment or drainage area is 184000 km2 while its surface area is 1120 km2 and its maximum depth is 28 m. It is 365 km long and a maximum 10 km wide.
