I remember reading some stocking reports in the past that indicated a high rate of stocking walleyes in that lake. I've heard of them being caught, but I have not caught any myself (though that's not sayin' much)... :)
McIntosh has a ton of Shad, and I mean a ton. They stocked Walleye in it and they were doing well for a while until the lake drained down. Then the Walleye population was cut about in half. White Bass have been doing fairly well there and they even stocked wiper recently. The Wiper are still small.
Back in the day before it was open to the public there used to be a healthy population of big crappies. These days I feel like the Crappie are more rare because the shad out compete them but they still are there.
My advice fishing there. Use things that look like shad. Also embrace the Carp! Carp are fun, and there are some serious bruisers in there.
