I know the lake like the back of my hand for boating, bars, and restaurants. However, I don’t fish it too seriously… What mile marker are you staying on? Have you been to the lake before?
If you are planning on fishing on a weekend, good luck. Weekdays will be your best bet. A lot of the fish in the lake reside around the docks. It is a fantastic Largemouth Bass lake. Find just about any cove that is a little quieter and cast your typical bass baits in between most any docks, boat slips, etc. There’s also a good amount of sunfish/bluegill/crappie around docks. I have had a lot of fun catching some channel cats as well off of our dock while hanging out. Put on a wad of worms, stinkbait, chicken liver, etc. and cast it out as far as you can! I don’t know about any walleye fishing on the lake, other than there are a few of them.
Lake of the Ozarks is a pleasure boating lake for me (and thousands of others), I just don’t do any serious fishing while there. But there are great fish to be caught!
