Thanks for sharing the temp and depth of the fish. I'm still learning the winter patterns. I happen to be the exact same water temp as you. Yesterday I found a nursery of crappy in 35fow. Nothing but 4 to 7 inch fish. Then found 13 inch plus in 20fow. It took 1.5 days to find those 2 two schools. I didnt see any structure on your graph. Were the fish roaming or stationary?
