What to throw right now

Fly anglers
HATCH-MODE FLY SETUP: 6 wt rod with floating line, 9 ft 3X-4X tippet. Hatch-on smallmouth on rivers eat dries you'd throw at trout: #10-12 Stimulator or Chubby Chernobyl, often with a #14 rust-color Hare's Ear dropper. On lake smallmouth, a #4 Game Changer (perch finish) twitched along rocky banks at first light covers more water. Cross-current + dead-drift on rivers, twitch-and-pause on lakes.

ON THIS WATER (Rock Island State Park): Great Falls Dam tailwater on the Caney Fork. Surge pool below the powerhouse holds stocked trout when generation is OFF, smallmouth/walleye downstream year-round. TVA generation is the single most important variable — check the schedule before you wade, and step back from the bank when the siren sounds. REGULATION: from the Rock Island boat ramp upstream to Great Falls Dam, Jan 1 - Apr 30 is single-hook-only (one lure, one single-point hook) per TWRA fishing-regulation exceptions — leave trebles in the box for that 4-month window.

Below the powerhouse zone (Caney Fork proper). 6 wt floating line, weighted #4 olive Clouser quartering upstream into the head of each pool, mend hard, strip back. The pocket water below the powerhouse is the most consistent smallmouth water in the park.

8 wt rod, integrated intermediate or floating line, 8 ft of 16-20 lb fluoro tapered down (4X butt to 0X bite). #4 deer-hair frog or #4 popper on calm warm mornings; #6 Clouser in chartreuse/white or olive Game Changer on overcast days or deeper. Cast tight to cover (overhung wood, dock corners, weed edges), let the popper sit 4-6 seconds, then a sharp pop. For sub-surface: cast across to the bank, let the streamer fall, then 2-3 ft strips with hard pauses. Strip-set hard; bass jaws are bony and you need the line tight to drive the hook.
Spinning / casting anglers
HATCH-MODE SPIN SETUP: medium-light spinning combo, 8 lb braid + 6 lb fluoro leader. River: 1/16 oz brown jig + 2" smoke craw trailer ticked along bottom seams, smallies hammer it during the hatch as they key on emerging caddis nymphs. Lake: tiny 1/16 oz hair jig under a slip-bobber rig drifted along rocky shorelines. Surface action: 1/8 oz Yellow Magic popper twitched dead-slow with 5-second pauses.

ON THIS WATER (Rock Island State Park): Great Falls Dam tailwater on the Caney Fork. Surge pool below the powerhouse holds stocked trout when generation is OFF, smallmouth/walleye downstream year-round. TVA generation is the single most important variable — check the schedule before you wade, and step back from the bank when the siren sounds. REGULATION: from the Rock Island boat ramp upstream to Great Falls Dam, Jan 1 - Apr 30 is single-hook-only (one lure, one single-point hook) per TWRA fishing-regulation exceptions — leave trebles in the box for that 4-month window.

3/8 oz football jig + rust craw trailer hopped along the bottom seams below the powerhouse pool. Generation ON: stay back from the bank; smallmouth still bite from the scour holes off bigger riverside rocks, but you can't wade.

BAIT OPTION: Live crayfish on a #4 light-wire with one BB shot, drifted through the soft slots between boulders downstream of the surge pool. Most consistent producer on this section.

Medium-heavy 7' rod, 20 lb braid + 12-15 lb fluoro leader (or straight 12 lb fluoro on a baitcaster). Texas-rigged 7" watermelon-red worm with a 3/16 oz tungsten weight + 4/0 EWG hook is the all-conditions standard. For active fish: 1/2 oz spinnerbait slow-rolled along points + drop-offs. For deep summer suspended fish: 3/8 oz football jig + craw trailer hopped along 12-18 ft ledges. Post-front shutdown: switch to a weightless wacky-rigged 5" Senko in green pumpkin, work it dead-slow next to cover.

Per-species breakdown & tactics

Pick a fish, then Fly, Spin, or Colors. Your last pick is remembered.

Best window: morning

HATCH-MODE FLY SETUP: 3-4 wt rod with floating line, 7.5-9 ft tapered leader to 5X tippet. #14 yellow Stimulator or #16 black ant on top, drop a #14 beadhead Hare's Ear or small olive damsel nymph 12-18" below as a dropper. Bluegill + redbreast hammer the dropper most of the time; the dry indicates. Cast into shade lines + along pad edges; let the rig sit 5 seconds before twitching.

3-4 wt rod, 9 ft floating line, 6X tippet. Roll-cast a #10 black wooly bugger or #12 olive damsel nymph into the shade under overhanging trees. Bluegill on calm sunny days hold tight to shadow lines; landing the fly within 18" of the shadow edge produces fish, landing it in open sun produces refusals. Let the fly fall 3-4 seconds before stripping; bigger bull bluegill grab on the drop.

Flies: Black Wooly Bugger #10, Olive Damsel Nymph #12, Small Black Beetle #14

Small chartreuse bugger or soft hackle under an indicator. Twitchy strips.
