I do not believe fall turnover occurs until the water temperature gets below 40 degrees. How cold was the water?
I did some research on this from the DNR website as I remember more than a few posts on lake water temps for turnover from this forum. The DNR lists the tipping point as 39 degress Fahrenheit. We definitely didn't have those temps --- probably upper 50s to 60 degree water maximum temps.
In contrast, I was just on Snowbank, Disappointment and water temps were fine and fish were biting so I think the problem fixed itself.....starting to think "portable fish finder again....."

I am posting this question because I think that at least along the Gunflint (bwca) that last week was too early for turnover. A paddling friend and I decided to hit Canoe Lake (East Bearskin EP) via Alder. We basecamped starting last Friday, the day that patchy frost hit that part of the bwca. Temps warmed to 50s during the day and went down to mid/upper 30s during the nights. We saw a lot of mist /fog rising off of our lake (Bearskin was fogged in when we put in Fri. AM) just about every morning.
We fished Canoe, Alder, Crystal, East Bearskin and a few smaller lakes in between. No luck. Not even a bit! We emptied our tackle boxes: spinners, jigs (plastics and minnows), spoons, deep divers, trolling raps, floating raps...everything. We didn't even see fish rising.
We finally theorized that the cold snap must have put the fish in a "wait-and-see" mode where they were not biting -- at all.
