I was on Norfork two weekends ago. Water was 40 degrees each morning and the air 32 as we started the boat. Sat we were up near Udall in your state hunting white's or eye's.
To much sun and a lot of boats were out, we did not do any good. Talked to one boat taking out, they had got 9-10 crappie. I did not see any of the other boats around us catch any fish.
I try to fish Norfork in the spring and fall while the big kids should be in college and not on the lake. I have better luck on crappie on Bull Shoals in the Theodosia area. But I have a lot to learn about NorFork and the lake.
If you read the fishing reports, The water temps are coming up and they are starting to catch fish
