Video: Testing Passage of Adult Rainbow Trout Through Natel's FishSafe Restoration Hydro Turbine (RHT)
July 8, 2022
The most recent Natel/Pacific Northwest National Laboratory test of 186 large rainbow trout measuring up to 500 mm (19. 7 inches) in length, found no meaningful difference between the fish passed through Natel’s 1.9 meter (roughly 6 feet) in diameter turbine and the control group, indicating that the RHT allows safe passage of some of the largest fish ever successfully passed through a compact hydro turbine.

The results of the study demonstrate that the RHT is an effective way to pass juvenile alosines downstream at hydropower facilities.
