I haven't fished yet, but my GSH have been hitting pellets even tho water temps are in the low 40s. Not a crazy feeding, but they are rising. I am amazed they are feeding in that cold water.
We have 50's for several days, I may head out this weekend and try the slip bobber approach ala Cecil. I do have pretty crazy blooms going right now - visability went from 6-8' to 24" in a matter of 2-3 days right after ice out.
