Why biting in one end of the lake, not the other any more?
I'm fishing a lake that has a school I fished reliably from November until about three weeks ago. The school is still there but is refusing to bite. Meanwhile, fish are biting readily in another end of the lake. Temps are the same in both spots. Food source, same. Fish are set up in a biting pattern but refuse to bite. I'm confused by a school that is staged to eat, just like usual, but is no longer eating and hasn't been for several weeks. Thanks for pointers!
