If so, it would be prime habitat for aquatic worms. They're much more common than people realize.
Try scooping out a handful of the bottom muck and see what you get. I betya you come up with a a bunch of little wigglers.
I'm not much for the "worm and a bobber" tactic but if you find these aquatic worms that's exactly what you should try.
A marabou worm jig fly under an indicator.
Cast it out, give it a twitch, let it sit..... strip it in a little, do it again.
Or a San Juan Worm or a beadhead Woolly Bugger.
If all else fails and you just have to get a tug on the line no matter the cost to your pride: mini-marshmallows sprayed with WD-40. I have second cousins in Montana who never fish with anything else.
