the post spawn crappie are starting to bite on gibson. every year they do something that amazes me . they bite shallow. they have started to bite in our old boat dock. we usually catch fish 8 to 12 feet deep but from now until mid august you can catch a mess of really nice keepers 4 to 6 ft. deep. the temps are hotter than a 2 dollar pistol in an old tin covered boat dock but so is the crappie fishing.1 1/2 to 2 inch tube jigs work best. maribou jigs will work but not as well.hope this helps someone.
