White drum can be caught in pretty much any flowing stream south of the Missouri River. Any creek mouth on LoTO or Truman should be stacked with them after a decent rain.
The trouble with that idea is getting them home alive. If you could catch a couple them <12" it might be do-able.
Any bigger than that they are very difficult to transport. 5lb+ size will croak in less than 15 minutes if you toss him in an aerated livewell on a boat.
But if you were able to pull it off... they will hoover some crayfish...
