I found a lake to fish in that has a mossy muddy bottom & is only about 10-12 ft. deep at its deepest point. No cover in water such as trees, limbs, etc. Grassy bank all the way around. There are a few cattails in the shallows. Would I be better off fishing tightline on the bottom for channels or possibly using a float rig? I always use nightcrawlers for bait & sometimes cut fish. I know catfish tend to come into the shallows at night to feed. Any suggestions?
