Anecdotally, after fishing in the Big Manistee River in Northwest MI for about 20 years. The salmon population has definitely dwindled from my experience during our last few annual fishing trips. We tend to go right around the time of the "Run", where the fish come into the river when lake Michigan gets cold. I've only caught maybe 1 the last 3 years I've been where usually it's 4-12 a trip (1 week). All anecdotal but the zebra mussel issue in the river has gotten insanely bad. The entire riverbed feels like dead shells and they're starving the river of nutrients. It's been a huge loss and I've stopped contributing to Manistee's tourism as a result. Huge bummer.
