My best friend owns and operates "Chauffered Guide Service", Ken Erb and I have been fishing with him for 8 years. Retired St. Louis fireman and a very good fisherman. He has been fishing mark Twain Lake since it reach it's normal pool the first time some 25 years. Too many variables to list when the crappie are in the middle the spawn. On average the Mark Twain spawn commences from middle to late April to sometimes as late as Memorial weekend. I just received notice that the old Missouri Department of Conservation is no longer going to post the weekly fishing reports that they have been posting in the St. Louis Post-Dispatch for over 40 years and will discontinue their weekly emails. This is fact by the way because I read in their last monthly publication and emailed them and the response was that anglers to day have much greater fishing information resources than ever before and the MDOC is no longer neccessary. They are just getting lazy the truth be known. When I was a guide out of Fall Creek Trout Dock & Campground in the late 70's and the St. Louis Post - Disptch would call seeking fishing information. Well no one would say fishing sucks I would stay home until fishing improves and lose the revenue. All dock owners would say many nice fish have been coming in over the last several days, the fisherman would show and most wouldn't do well and we would look them in the eye and would say, "YOU SHOULD HAVE BEEN HERE YESTERDAY!"
