Most fishes are managed under statewide regulations with the exception of largemouth bass, which has a 18-inch minimum length limit and a 5-fish daily bag.
Both the Hackberry and Aquilla Creek arms are loaded with standing timber and brush. The main pool close to the dam is mostly devoid of timber. A word of caution: when navigating up the creek arms of the lake, watch for large tree stumps just under the water!
Tips & Tactics: Largemouth bass fishing can be excellent on Aquilla. The combination of stained water, ample heavy cover, and light fishing pressure means plenty of big bass to catch. Fish spinner baits, jig and pork combos, and plastic worms in and around heavy cover. Tree lines, fencerows, and creek channels are good places to start. Crappie are usually found on submerged brushpiles and large isolated trees. Live minnows seem to be the preferred bait. Catfish are caught drift fishing flats or on trotlines set around shallow, brushy areas. Shad, cutbait, or bloodbait will all work. White bass are caught trolling small tailspinners, jigs, and spoons across windy flats.
