Salmon struggles at barriers

[@Fox7466]

Theres a huge dam on a Dee tributary at Peterculter, pike and reasonable sized trout in it, they installed a fish ladder and in 2014, a couple of years later they were trapping smolt on it. Theres a couple of dams about that have the same potential definently. Least most of our estates are new and we dont have the sewage discharge to the same extent as the towns/cities.
