Clearwater is awesome for walleyes but it all comes down to boat control. My dad had a cabin in there and I'd try to go with him he diesnt really understand how to fish walleyes...we'd go from 6' of water to 50' in a matter of seconds and never caught anything. Structure is pretty intense out there.
But when I graduated took in upon myself to figure out some spots and didn't take long to hone in on what worked where and how. Regularly get 8-16 walleyes in like 3 hrs...which I consider good at least especially for a "metro" lake but I'm not a walleye fisherman so maybe not that great. Biggest was 27" but catch a lot in the 14-20" range...at least back then. Haven't fished it since and that was like 15 years ago now not sure if stuff has changed but kinda got the urge to try it again
