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.

Any thoughts? Did we miss something?
