Salmon and Sea-trout can jump over waterfalls – surely they can get over Beaver dams?
No. Both Salmon and trout are good at jumping over obstacles but only if these have a good flow of water over the top of them and a deep pool below them. Beaver dams generally have neither. Although Sea-trout are actually better than Salmon at getting over barriers that require more of a “scramble” than a clean jump and there are places in Scotland where Sea-trout can pass and Salmon cannot, Beaver dams are a major problem for them in the Baltic countries.
