The hydroengineering system includes a spillway dam 92 m. long at the crest, with four spillway openings designed for a water flow of 3,400 cu m per sec; the system also includes concrete nonoverflow dams 300 m long, a single-chamber lock, and a hydroelectric power plant building 129 m long. The hydroengineering system creates the Ust’-Kamenogorsk Reservoir. Construction of the power plant was begun in 1939 and completed in 1954.
