Fish Friendly Tide Gates

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.

The fish-friendly flood gate attachment converts new or existing tide/flood gates to meet fish passage requirements.

For new builds we can provide a stainless-steel flood gate and fish friendly attachment.
