Re: lake McConaughey
For a guided walleye trip I would recommend "Walleye Express". I think his name is Steve Mullen. I went with him last summer and had a great time. Met him on the North Shore. He provides everything, tackle, etc. It's a full day of fishing and at the end of the day he and his wife cleans and fillets and bags all your fish for you. I ended up with 3 nice size walleyes, one perch, one catfish.
As for a resort, we stayed at the Eagle canyon campgrounds. Very nice campground with cabins, rv sites, primitive tent sites, etc. Has a general store. It's on the south side of Big Mac. Very quiet. Reasonably priced.
Hope this helps
