I have a similar, single, very clear sandy ring in the shallows as well. I see nothing at the bottom and schools of minnows swim over and through it. No adult fish seen. I'll keep an eye on it. I have no LMB or SMB, only RES, LES but I'm not sure if any of those are large enough to spawn yet.
Experts, where do RES hang out in reference to their spawning circle? Bluegill tend to hover over the middle but how about RES?
