The results show that unsteady interactions between upstream wake, tip leakage vortex/mixing zone and downstream passage vortex are the main factor affecting turbine endwall secondary flows.

So the only life stage that may be affected by downstream passage is juvenile salmon.

Along our own Columbia River here in the Pacific Northwest, more than $7 billion has been spent since 1950 on efforts to save salmon speciesby stock enhancement, constructing fishways such as ladders or steps, screening irrigation diversions, rehabilitating habitat, and providing downstream passage.
