What to throw right now
Per-species breakdown & tactics
Pick a fish, then Fly, Spin, or Colors. Your last pick is remembered.
Best window: morning
3-4 wt rod, floating line, 5X tippet. #10 yellow or chartreuse popper. Cast within 12" of the weed edge or lily-pad pocket and let it sit dead-still for 3-5 seconds. Twitch, pause, twitch. The first twitch after a long pause is when the bull bluegill eats. Strip-set, no rod lift. Overcast skies push bluegill into the upper 2 ft of the water column, they'll travel 4 ft to crush a popper.
Flies: Yellow Popper #10, Chartreuse Popper #10, Hare's Ear Nymph #12
Small chartreuse bugger or soft hackle under an indicator. Twitchy strips.
In a few hours
Ultralight rod, 4 lb mono. Yellow Beetle Spin or 1/16 oz chartreuse jig with a small tail spinner. Cast parallel to weed edges and retrieve just fast enough to keep the blade turning. For surface action, switch to a 1/16 oz popper (Rebel Pop-R Jr in chartreuse) and walk-the-dog along the pad edge; pause for 3 seconds after every 2 twitches.
Lures: Red Squirmy worm #12 OR olive damsel nymph #12 under a tiny pencil bobber, yellow beetle spin, chartreuse 1/16 oz jig
Beetle spin or tiny jig tipped with wax worm. Slow roll past beds.
In a few hours
- Natural / shad Disappears correctly in clear water. Invisible for the wrong reason once stain cuts visibility.
- Watermelon red The clear-water bass standard. Red flake reads as craw without spooking pressured fish.
Best colors right now: chartreuse, yellow, white
Good colors for clear water (fall): natural nymph, olive, smoke
Sight feeders in shallow water. Small and bright beats big and natural except in the clearest spring pools.

Best window: after dark
Not a practical fly target most days. Heavy Clouser dredged deep is the novelty play.
In a few hours
Lures: Live bluegill (4-6") on slip-bobber over a brush pile, Chicken liver in a mesh bag (low turtle attraction), Shad-gut dough on a #2 treble (firm bait stays on the hook), Cut skipjack on 7/0 circle (large hook + heavy weight discourages turtles)
Cut bait on bottom rigs. Put scent in the current seam and wait.

- Watermelon red The clear-water bass standard. Red flake reads as craw without spooking pressured fish.
Best colors right now: natural, live
Good colors for clear water (fall): natural cut bait, nightcrawler, live shad
Catfish hunt by smell first. Color barely matters, contrast and scent do. Dark baits with bloody scent win in stain.
Full color matrix for clear water
- Turtle pressure is heavy on small TN lakes (Cane Creek, Standing Stone, TWRA family lakes, plateau state-park lakes) from May through September, especially after sunset.
- Live bluegill on a slip-float OR chicken liver in mesh outfishes loose cut bait when turtles are active.
- If you commit to cut bait, use the largest possible chunk on a 7/0+ circle hook so turtles can't strip it.

Best window: first light
5 wt rod with floating line, 9 ft 5X tippet to a #8 Crappie Candy or 1/32 oz marabou jig. Spring spawn (55-68°F water): dap or short-cast under dock corners + into brush; let the fly fall 2-4 ft then twitch once. The fall does the work. Summer + winter: switch to a sink-tip or full intermediate line, count down to the brush depth (8-12 ft), then microscopic 2" strips. Crappie eat lightly, set on any line stop, no rod sweep.
Flies: Crappie Candy #8, Marabou Jig 1/32 oz
Chartreuse marabou jig or small Clouser under an indicator. Count down to the school depth.
In a few hours
Ultralight 6'6" rod, 4-6 lb mono OR 8 lb braid + 6 lb fluoro leader. Spring: 'shoot' a 1/32 oz curly-tail grub far under docks by bow-and-arrow casting the rod tip + flicking the lure. Let it fall on slack line; strike on the drop. Summer: vertical-jig a 1/16 oz hair jig directly above marked brush piles; 6" lifts, 3-second pauses. Minnow on a slip-bobber set 6" above the brush is the bail-out when the bite is light.
Lures: 1/32 oz curly grub (white/chartreuse), 1/16 oz hair jig, Minnow under slip-bobber
Chartreuse jig tipped with minnow, vertical over brush. Slow fall triggers the eat.

- Natural / shad Disappears correctly in clear water. Invisible for the wrong reason once stain cuts visibility.
- Watermelon red The clear-water bass standard. Red flake reads as craw without spooking pressured fish.
Best colors right now: chartreuse, white, pink/white
Good colors for clear water (fall): smoke shad, natural minnow, pearl white
Crappie hunt by flash and vertical profile. Chartreuse and white outproduce naturals in every stain level except gin-clear.
Full color matrix for clear water
- Crappie bite shuts down hard during post-frontal high-pressure days; commit to spring + fall windows where you can.

Best window: first light
Flies: Clouser Minnow #6 (chartreuse/white), Frog Popper #4
Olive wooly bugger or black game changer. Dark silhouette first, drop to rust nymph if refusals.
In a few hours
Lures: Texas-rigged worm (watermelon red flake), 1/2 oz spinnerbait (white/chartreuse), 3" soft jerkbait (smoke shad), 3/8 oz football jig + craw trailer (deep summer)
Black and blue jig or chartreuse spinnerbait tight to cover. Stained fish hold on wood and rock edges.
In a few hours
- Natural / shad Disappears correctly in clear water. Invisible for the wrong reason once stain cuts visibility.
- Watermelon red The clear-water bass standard. Red flake reads as craw without spooking pressured fish.
Best colors right now: watermelon, chartreuse/white, shad
Good colors for clear water (fall): watermelon red, natural shad, green pumpkin
Bass see red and green well and chase high-contrast silhouettes in stain. Black and blue reads as a shad or bluegill profile when detail drops out.
Full color matrix for clear water
- 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.
