We sure spanked the crappies yesterday. Water temps were varied. I measure at 6 feet deep since I don't catch fish off the transom where everybody's water temp comes from if the go the way of the locator. At 6 feet we found anywhere from 54 degrees to 58 degrees. Universally the 58 degree water was deep and provided the best fishing when we focused on the break into shoreline shallows. The fish haven't moved to the thin water yet but I'd imagine by this time next week we'll see so of that.
Got nice fish yesterday too. We saw some smaller [9 1/2" to 10 1/2"] hens, the big fish were all males and they're just now taking on some color.
Larger baits were working good too. Fun day, but hard on the tackle supply going into sunken wood. I guess that's part of the game. Good luck up there Dutch.
