What to throw right now

Fly anglers

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

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.

Hatch: 71% (terrestrials) Active hatch. Fly imitations and small surface bugs are working.

Topwater commits hardest in the first 90 minutes after sunrise on calm warm mornings, see /learn/technique/topwater-bass.
Bluebird high-pressure days after a cold front kill the topwater bite; switch to slow soft plastics in deeper cover.

Best window: first light

9-10 wt rod, integrated intermediate or Type 3 sink line, 6 ft 30 lb fluoro to a #1/0-2/0 Clouser or 6" articulated baitfish. For surface schools at dawn: cast LONG into the boil (60+ ft), strip-strip-pause back through the school. For sub-surface holding fish: count down the sink line to the depth you're marking on the graph, then 18-24" strips. Strip-set hard; striper jaws are bony and a missed set is a missed fish.

Stripers stress hard above 78°F surface temp. If you're trophy-hunting in July-August, fish dawn-only on Cherokee or Norris and bring an aerated bait tank.
TWRA stocks Cherokee, Norris, Watts Bar, Tims Ford, Cumberland tailrace, the trophy water is Cherokee + Norris.

Lake walleye on a fly is a niche game. 9 wt with a fast-sink 350-450 grain integrated head; 6 ft 20 lb fluoro to a heavily-weighted Clouser or articulated baitfish pattern in chartreuse-over-white. Troll-fish from a kayak or skiff over 20-30 ft ledges at 0.8-1.2 mph using the wind for drift. Or jig vertically with the heaviest fly your rod can handle, count down to bottom, then 6" lifts. Productive but slow versus spinning gear; treat it as a fun-with-friends approach, not your meat-and-potatoes.

Niche on fly. Heavy chartreuse Clouser trolled along 20 to 30 ft ledges.

Lake walleye scatter in summer; without electronics you're searching blind. A graph + structure-aware troll is the difference between zero and double-digits.
