Tailraces below reservoirs can provide some of the best fishing for lots of big trout. Big browns migrate upstream and concentrate below dams during their annual spawning run. Big tailrace brown trout are hungry in fall and can be caught on minnowbaits, spinners, and softbaits like curlytail grubs, or by drifting smaller baits like worms, nymphs, eggs, and doughbaits in micro sizes. Focus on current edges, deep runs, and areas with refuges from flow like instream boulders and eddies that form behind instream objects. Be careful, as water conditions on reservoir tailraces can change quickly.
