June 6, 2013 on Nizhne-Tulomskaya HPP it was opened the fish ladder, which is a unique hydraulic structure and marked by environmentalists as unrivaled in the world in simplicity and convenience.

The construction is 64 wells, simulating a mountain river.

Fish ladder was firstly tested in 1936, and since then every year in early June, the salmon came up to it and rushes to spawn upstream Tuloma. On the way fish lurk seals already sailed to the tailrace of Nizhne-Tulomskaya HPP in search of easy prey. In August, the salmon with the new offspring will return to the sea.

On the eve of the opening of fish pass power engineers eliminated the defects of concrete structures and cleaning of wells from snow, ice and debris. In addition, at the time of spawning fish the repair of roadway on the hydroelectric dam was suspended.

"We created conditions favorable to the passage of fish. Salmon to come in the fish ladder for some time the work of hydroelectric number 4 is suspended, idle spillway is closed. We do our best to reduce the impact of industrial design on natural processes and contribute to the conservation of populations of key commercial fish species in the region ", - said the director of Tulomskie HPPs Cascade Alexander Tkachenko.
