Abstract:
A fish passage system is provided that includes a first weir and a second weir upstream of the first weir. The first and second weirs are each moveable between a deflated condition and an inflated condition. The fish passage system further includes a controller to move the first and second weirs between the inflated and deflated conditions to create at least one pool between the first and second weirs so that fish can migrate upstream and/or downstream of the system without having to jump the first and second weirs.
