Many technologies are available to safely pass adult fish upstream over dams.  From fish ladders to trap and haul facilities, a lot of work has been put into research and development of these systems.


Our Fish Friendly Tide Gates are a rugged design, that can be calibrated to open gates when water is low, allowing for fish passage.
