Fishing Tip: The heat is beating down on Arkansas’s lakes and reservoirs, but it’s a great time to catch trout in the tailwaters of Greers Ferry, Beaver and Bull Shoals lakes. The water is cool and the generation has been low, offering excellent opportunities to wade. Be sure to get out early and fish until the water rises. Watch the water level. As the water rises, you need to find high ground to avoid being trapped.
