In modern Russia, there are 27 fish passage facilities. A dam was built on the Amazar River in 2017 and a reservoir was formed. For fish migration, the dam is equipped with a fish ladder. The speed of the current is a determining factor for the passage of fish through the fish passage. The study of the speed regime in the chambers of the fish passage during the spawning migration of fish of different fish species made it possible to establish the speed of water flow (m/s) overcome by the fish in the inflow holes, depending on the size and type of fish. For greater efficiency of the passage of fish through the fish passage, it is necessary to control the flow of water to maintain the best speed regime.
