SWPA, SouthWest Power Administration has been running one unit of generation for two hours usually starting at 5pm and usually running for two hours, Monday through Friday. It's subject to change so always check the USACE Little Rock app for the generation schedule before heading out. The weekend generation schedule has been about the same.
The best bite has been early morning while there's still water falling out from last night's generation. The evening bite has been good as well. Try fishing anywhere where there's current. The fish seem to be in the deep holes and oxygenated shoals. Or whatever you can get a drift. Egg patterns, Midges along with small pheasant tail nymphs have been my go to.
