Interesting observations. I was wondering if the didymo takes over that stream in the winter/early spring? Brown trout numbers have decreased in several areas of Alberta over the last decade, one factor finally being discussed is didymo and effects on incubating eggs during the winter. Just wondering if it could be occuring there?
Would definelty be nice to see some research done along the Raven to see what's occuring fish population wise. Appreciate your takes on it.
