Tanneycomo if there is low generation, would be closest good trout fishing. Tanneycomo is a short reach of the White River above Lake Tanneycomo in Branson, MO.
If you have time to drive another 1.5 hours and want to try another spot then fish the White River in AR below Bull Shoals Dam.
Both are tail waters that can fluctuate quite a bit. So be careful.
Check out the website for Steve Daly's Ozark Fly Fisher. He gas a good app with links to the dam gauges. Give the shop a call for further info, they are good guys!
