Along with Kyle's list, I would add The Toad Fly and Jeff Guerin. Littlemissouriflyfishing.com has some good info. Though he's now in north Arkansas, see if you can get in touch with Duane Hada. He went to school in, I believe, arkadelphia, and stomped around in a lot of the warmwater streams down that way. He's a wealth of knowledge on smallmouth. Gene Backwoods has some fishermen that work there. In particular there used to be a fellow named Red that knew a fair amount about some of the Stillwater down that way. If you're interested in fishing those get on SWEPCOs email list and they will send you out the release schedule. Another good tool is breakage phone app USACE Little Rock. Its the corps app with good projections and real time information. Also, I'm a member of the Arkansas Fly Fishers. We meet the third Monday of the month at Whole Hog Cafe. We're a decent group of folks. http://arkansasflyfishers.com/
and you can find us on facebook.
Kyle, I'm sure I've seen before, but are you in Arkansas? I'm in Little Rock.
