The settlement of Hydroelectric Station-1 is located in the upper zone of the Ayusai Gorge, close by confluence of the Ozernaya and Kumbelsu Rivers, at the foundation of a large plain earth dam blocked the Ozernoye Gorge. The settlement with a 'GULAG' camp for haul Japanese erected the Bolshaya Almatinka sections of hydroelectric plant was built in the second half of 1940-s. They punched tunnel from the Hydroelectric Plant-1 up to the crest of dam of the Hydroelectric Plant-2, where from water falls to the turbine. The tunnel functioned up to day. The captives manufactured in-situ pipes for the pipe-line from lake up to the Hydroelectric Station-7 in Pyatiletka settlement situated at the debouchement. Pipes of one meter in diameter were made of wooden laths by barrel technology. The pipes were trussed at interval of 20 cm. The frequency ratio is stipulated with significant pressure of water in the pipes. Pipe-line expanses for over 15 km. Surely, the pipes were not hermetic; they ouzed out with water and sometimes burst out with small fountains convenient for cooling while ascending along the pipe-line. At the end of 1960-s wooden pipes were changed with metal ones. When Japanese prisoners were discharged, the camp was transformed for the reformatory of juvenile delinquent; later it became a rest-home 'Kommunalnyk'.
At present a number of private holiday areas occupy the territory of the settlement, but evidence of past - a building of solitary confinement with chambers for prisoners has been preserved beyond the high wall.
Up to the 1950-s in the rocks above the settlement there was Almaty waterfall. Today only dried up riverbed of the Ozernaya River has been seen, as lake water is taken for the needs of hydroelectric plant and water - supply of the city.
The concrete wall above 15 meters high was erected along the channel to protect the settlement from frequent mudflows running down the Kumbelsu Gorge.
Protracted winding road to the Bolshoye Almatinskoye Lake begins from the Hydroelectric Plant-1.
