SAMPLE GUIDE REPORT · WEDNESDAY, AUGUST 12, 2026
Hot water, bluebird heat, and falling pressure. Fish the first and last light hard, then hunt deep shade and timber.
WATER 88°FAIR 90°FWIND 11 MPHSEASON SUMMERPOOL -2.5 FT
Water's sitting at 88 degrees, which is past comfortable for largemouth. They're in survival mode during the day, tucked into the deepest shade they can find with good water movement. The pressure's dropping ahead of some weather, which will fire them up once it rolls in, but right now in this blazing sun they're lazy and tight to cover. Early morning and dusk are your real windows because that's when they'll hunt shallow. Midday is a grind. Pool's down 2.5 feet, so fish will be a bit tighter to deeper structure and creeks than normal. If the sky stays clear and the sun stays brutal, keep expecting them deep and sulled up until the light changes.
The day's game plan
EARLY MORNING · 6:55 AM to 8:30 AM
Shallow timber, creek channel swings, and riprap near deep water access. Focus 4 to 10 feet, tight to structure.
4-inch green pumpkin finesse worm on a 1/8 oz shaky head. Fish it slow right on the bottom, work it a foot or two then pause. Light line, 6-pound fluorocarbon.
Bass push up shallow to hunt shad when the sun's low and they don't feel exposed. This is the most reliable bite of the day. The low angle light lets them see forage without scanning wide, so they're willing to chase. Work the structure thoroughly because they're concentrated here.
MORNING · 8:30 AM to 11:00 AM
Transition zone between shallow timber and the deeper channel, usually 12 to 18 feet. Look for brush or fallen trees on the edge of structure.
Watermelon/red flake craw pattern 3.5-inch worm on a drop shot, 1/4 oz weight. Vertical drops and small hops, keep it tight to the structure.
As the sun climbs higher, bass slide off the shallows but aren't committed to the deep yet. They stack on ledges and structure edges where they can drop down fast if the light gets too bright. The water temp is pushing them to move, so the transition zones are where you'll intercept them during this window.
MIDDAY · 11:00 AM to 3:00 PM
The deepest timber and channel ledges available, 18 to 25 feet, where there's shade from structure or overhanging banks.
Black or black/blue 5-inch stick worm, rigged Texas style on a 5/16 oz weight. Drag it slow along the bottom, keeping contact with structure. Pause for 10-15 seconds in the thickest cover.
Sun is peak, water temp is cooking, and bass are hunkered down in the thickest shade they can find. They're not hunting, they're surviving. A slow presentation right on the cover gives them the easiest meal to strike without energy expenditure. Dark colors give them a clear silhouette in the deeper water.
LATE AFTERNOON · 3:00 PM to 5:30 PM
Same deep structure and timber as midday, 18 to 25 feet. Begin transitioning to slightly shallower ledges and brush piles near the 12 to 18 foot range as water temperature stress lightens.
Junebug 4-inch worm on a 3/16 oz jig head. Shake it softly on the bottom, minimal movement, 2 or 3 foot drifts with long pauses between.
The absolute heat of the day is passing. Bass are starting to think about feeding again, but the sun's still bright and the water's still hot so they're cautious. Junebug silhouette works in warm water, and the jig presents a small profile they can examine without heavy commitment.
EVENING · 5:30 PM to 7:00 PM
Shallow timber, channel swings near flats, riprap and docks. Work 6 to 14 feet, focusing where structure funnels into deeper water.
Green pumpkin or watermelon craw 3/8 oz crank style jig, fished around wood and near edges. Short pitches and short hops, keep it in the strike zone.
As the sun angles down, bass feel safer shallow again and the water is still warm enough they'll roam and hunt. The falling pressure ahead of incoming weather is starting to wake them up. They're feeding with more conviction now than midday. Cover the structure quickly with reaction baits because they're looking up.
DUSK · 7:00 PM to 8:24 PM (sunset)
Shallow flats, shallow timber, dock pilings, shallow riprap. Work 2 to 8 feet. Same areas where early morning was productive.
Black or black/blue 4-inch finesse worm on 1/16 oz shaky head, worked slow right on the bottom, or a small black chatterbait 3/8 oz with a 3-inch black paddle tail, worked with a steady retrieve just off bottom.
Low light and dropping pressure combine to turn on a solid bite. Bass are aggressive, willing to chase, and covering ground hunting in the shallows. This is the second best window of the day. The chatterbait gives them vibration and silhouette they can track in fading light. Fish this period hard.
NIGHT · 8:24 PM to 6:55 AM next day
Same shallow flats and timber as dusk, 2 to 8 feet, plus dock lights if any exist. Work slowly and thoroughly.
Black 4-inch worm on a 1/16 oz shaky head, or black/chartreuse bladed jig with black trailer, worked slow with frequent pauses. Use heavier line (8 pound) because you can't see snags in the dark.
Pressure continues falling through the night and bass feed aggressively in the dark when the water is warm. There's no light stress. They hunt by feel. Slow, heavy vibration and silhouette work better than anything subtle. Most night bites come within 2 hours of sunset and from about midnight to 2 AM when the first solunar major hits. Fish the shallowest timber and structure you can find without hanging constantly.
Where to fish
Shallow Timber Flats — 2 to 8 feet · Fallen trees, standing snags, root systems near banks and creek arms Bass use timber as shade to escape sun exposure in hot water. Early and late light windows pull them shallow to hunt. These areas concentrate forage movement too.
Creek Channel Swings — 8 to 18 feet · Inside bends of creek channels with hard bottom or brush, outside bends with steep drop-offs Channels funnel bass between deep and shallow water. Inside bends create current breaks and forage concentration. Channel swings near shallow flats are primary migration highways in summer.
Deep Timber and Ledges — 18 to 25 feet · Brush piles, fallen timber, edge habitat where structure meets open water Refuge from midday sun. Bass pull into the thickest shade available when water temps climb into the 80s. Deep timber with nearby shallow access gives them the best of both worlds.
What to throw
Green Pumpkin Finesse Worm — 4 in · Green pumpkin · 1/8 oz (Early morning and dusk when bass are hunting shallow) Shaky head, slow bottom work with frequent pauses
Watermelon/Red Flake Craw — 3.5 in · Watermelon with red flake · 1/4 oz (Morning when bass are sliding between shallow and deep) Drop shot, vertical drops with small hops, work transition zones
Black/Blue Stick Worm — 5 in · Black or black/blue · 5/16 oz (Midday deep structure when heat stress is highest) Texas rig, dragged slow on bottom with 10-15 second pauses in thick cover
Black Chatterbait — 3/8 oz · Black with black paddle tail · 3/8 oz (Dusk and evening when light is fading and pressure is dropping) Steady retrieve just off bottom, worked through shallow timber and near docks
Junebug Finesse Jig — 4 in · Junebug · 3/16 oz (Late afternoon transition when sun intensity is dropping) Shake softly on bottom with minimal movement, 2-3 foot drifts and long pauses
How to work it
Shallow Cover Grinding — First light and last light when bass hunt shallow without light stress · Shallow flats and structure in 2 to 10 feet, especially early morning and dusk Work timber, riprap, docks, and shallow brush systematically, throwing at every piece of wood or shadow. Make short, precise casts. Skip baits under overhangs and docks.
Ledge Transition Fishing — Morning and late afternoon when bass position between deep and shallow · Channel edges, structure transitions, and dropoffs in 12 to 18 feet Cast uptempo toward shallow water and work baits down the ledge, focusing on the depth breaks where hard bottom drops away. Fish vertically as much as horizontally.
Deep Dragging — Midday when heat stress is highest and bass are conserving energy · Deep timber and channel structure in 18 to 25 feet Make long casts uptempo and drag baits slowly along the bottom in tight contact with timber and brush. Let gravity and patience do the work. Pause frequently and wait 10-15 seconds between movements.
Pro tips
Pool's down 2.5 feet, which tightens bass to structure and creeks. Fish channels and creek arms harder than usual because fish use them as highways when water level drops. Shallow flats lose appeal, so focus your shallow time on timber and cover, not open water.
Falling pressure means the bite will improve as the day goes on and definitely tonight. If you can stay out through the first solunar major at 1:48 PM, you'll see a small uptick. If you can fish into early evening and dusk, you'll see a much stronger one. The evening bite should be noticeably better than morning despite hotter sun because of that pressure swing.
Black and junebug are premium colors in bluebird sun on warm water. Bass see them as high contrast silhouettes even when visibility is perfect. Save bright patterns for clouds or stained water. In crystal clear sun like today, dark is your friend.
If conditions change
If a breeze kicks in or clouds roll over later, the shallow bite can extend longer into midday because bass won't feel as exposed and the water won't heat as fast. Widen your window on shallow structure and fish slightly higher in the water column. If the weather front moves in faster and pressure drops quicker, expect the evening bite to fire up earlier than normal. If the pressure holds or rises instead of falling, adjust down: go smaller, slower, and fish tighter to cover. Don't chase; let them come to you. If you get heavy rain and the water muddies, upsize everything to dark colors and add vibration with bladed baits and rattles because bass will hunt by feel, not sight.
