My family has a cabin on the Gasconade between Hwy 42 and Hwy 89. One of the members of our club has caught numbers of walleye - not on a consistent basis, mind you - over the years. They have been in the range of 4-5 lbs mostly, with the biggest being 7 1/2 lbs. Now this has been over the course of 15-20 years, with the events happening maybe once to twice/yr.
