Currently salmon and sea trout are unable to negotiate the weir effectively having to wait until high tide nearly overtops the structure allowing them to continue upstream. As a result accumulations of fish downstream have attracted predators, including seals, which have been regularly recorded taking salmon from below the weir as they waited to ascend the river.
The new pass incorporates the most modern technology on fish passage. No longer will the fish have to jump from pool to pool but will be able to ascend easily simply swimming through the pass unimpeded.
The pass design is known as a “super active bottom baffle” and will allow fish to ascend easily over a wide range of river flows. The specially designed baffles effectively reduce the water velocity within the pass so that fish can ascend without the need to jump.
