i went to spirir lake, iowa this spring and i went fishing in east and west lake okoboji from shore i saw a giant walleye some really big bass, some smallmouth a 45 inch muskie and pretty much every other fish!! i caught a 14 inch walleye on a sandworm a bull head and a sheepshead. i never did get to fish in big spirit lake but i heard there are some giant muskies in there. Has any one fished down there? it is in northwest iowa. highway 71 goes through it.
