SAMPLE GUIDE REPORT · WEDNESDAY, AUGUST 19, 2026
Water's warming into the sweet spot. Eelgrass edges and backwater points will hold fish looking to feed. Frogs and jerk minnows early and late, wacky rigs when the sun climbs.

Water's at 60 degrees and climbing out of the cool zone into comfortable feeding range. This is the window where largemouth shake off the slow summer lethargy and start hunting with purpose again. You're in that sweet pre-spawn staging phase where fish stack on secondary structure with deep water access. The river's clean, 1 to 3 feet in the main current and clearer still in the backwater backs. With the pressure rising after a drop and sun at 27 percent cloud, the bite will be strongest during the low-light windows and ugliest through the middle hours. If clouds build and wind stays light, the shallow bite can hold longer. If the sun locks in clear, the fish will pull off the obvious flats and stage tighter on edges with shade.
The day's game plan
EARLY MORNING · 5:30 AM to 7:30 AM
Eelgrass edges in Pool 7 backwater complexes and around Goose Island, 2 to 4 feet deep, especially where grass meets a drop-off or channel swing
Spro Bronzeye frog in natural black or brown over the mat, walk it side to side with steady rod twitches. Pair with a Big Bite Baits Jerk Minnow on a 5/0 hook in ghost shad or natural, work it with sharp rod snaps and pauses along the weed edge.
Largemouth are most aggressive in low light and the topwater bite lights them up when visibility is poor. They're staging on these edges because the grass concentrates bait and the nearby deep water gives them an escape route. The jerk minnow covers fish that won't commit to topwater but are feeding.
MORNING · 7:30 AM to 10:00 AM
Backwater points and secondary structure in Pool 8, especially around creeks that swing into deeper water, 4 to 6 feet
Wacky-rigged Gambler Ace stickbait in watermelon or green pumpkin, worked slowly with long pauses along the edge. Drop shot with a 3-inch finesse worm in natural shades, targeting any hard-bottom transition or rocky edge within 3 feet of a channel.
As light increases the fish pull off the super shallow flats but stay shallow enough to hunt. The wacky rig and drop shot are patient presentations that match the fish's willingness to look at a slower meal. They're not fully aggressive yet but they're feeding.
MIDDAY · 10:00 AM to 3:00 PM
Deeper weed lines and the green edge where grass ends and open water begins, 6 to 9 feet, or any main-river point with hard bottom near a backwater mouth
Swim jig with a creature trailer in green pumpkin or junebug, 3/8-ounce, work it slowly along the weed edge with pauses. Texas-rigged 4-inch Senko in watermelon or natural, pitched into any shade pocket, grass hole, or standing timber near the edges.
When the sun is up and pressure is rising, largemouth back off the shallowest flats and tuck into structure. The swim jig in that sweet contact with the weed edge keeps you in the strike zone. The Senko works pockets where a larger bait would spook them.
LATE AFTERNOON · 3:00 PM to 5:30 PM
Transition zones between shallow flats and deeper channels, 5 to 8 feet, including channel swing insides and creek mouths
Wacky rig in natural shades, fished dead slow. Jerk minnow in natural forage colors, retrieve with longer pauses than morning. Creature bait on a shaky head, 1/4-ounce, dragged slowly along any hard-bottom edge.
As shadows lengthen the fish begin looking up again and moving shallower to feed. These transition zones bridge what they've been doing deep and what they'll do at dusk. The wacky rig and jerk minnow mirror the early morning bite but the fish are not yet fully aggressive.
EVENING · 5:30 PM to 7:30 PM
Eelgrass edges and backwater flats in the upper, clearer zones of backwater complexes, 2 to 5 feet
Wacky-rigged stickbait in natural colors, work it slow with long pauses. Topwater frog in black or dark patterns, walk it over any grass mat or pad. Jerk minnow in ghost shad, work the edges with sharp snaps and pauses.
As light fades, the feeding window opens back up. The fish have spent midday tucked in but now they're hunting actively. The grass holds bait and the eelgrass edges are where they set up to intercept it. Topwater and jerk minnows trigger reaction strikes from fish that are fired up.
DUSK · 7:30 PM to 8:15 PM
Eelgrass flats and the edges around creek mouths leading into backwater points, 2 to 4 feet
Topwater frog in black, walk it steady over any visible grass. Hollow-body frog, hop and pause. Jerk minnow in shad patterns, work the edges with sharp snaps.
This is the best low-light window of the day. Fish are aggressive and feeding hard. Topwater and jerk minnows trigger strikes. The fading light keeps bass in the shallows longer than midday.
NIGHT · 8:15 PM to midnight
Eelgrass edges, backwater flats, and shallow points in the clearest water zones, 1 to 4 feet
Topwater frog in black or dark patterns, walk it steady. Jerk minnow in natural shades, retrieve with sharp snaps. Spinnerbait with a willow blade, 1/2-ounce, in silver or chartreuse, cast and retrieve steady along grass edges.
If you're night fishing, the waxing crescent moon provides minimal light so the fish hunt by feel and lateral line. Topwater and jerk minnows still work. The spinnerbait's vibration and displacement help them locate the bait. Stay on the shallowest, clearest edges where the forage is.
Where to fish
Eelgrass complexes in Pool 7 backwaters — 2 to 6 feet shallow flats, 8 to 12 feet on deep edges · Healthy eelgrass mats with clear water, edges where grass meets channel drops or open water Tournament-proven largemouth staging area. Grass holds forage, and the edges give fish cover and feeding depth. Clear backwater water keeps visibility high and encourages topwater and jerk minnow bites.
Goose Island area in Pool 8 — 4 to 9 feet · Secondary points with grass edges, creek mouths, transitions from shallow flats to deeper channels Major eelgrass and staging zone. Fish use the points as highways between deep and shallow water, and the grass edges concentrate bait. Proven in recent tournaments.
Pool 8 channel swings and main-river points — 6 to 15 feet · Hard-bottom points near backwater mouths, inside bends of the channel, edges where current meets slack water Fish stage here before sliding shallower to feed. The deep water access is critical. Fish these when the sun is high and largemouth pull back from the shallowest flats.
What to throw
Spro Bronzeye Frog — n/a · Black or brown · n/a (Early morning and dusk, over eelgrass and pads in low light) Walk it side to side with steady rod twitches, pause over grass mats, work the edges
Big Bite Baits Jerk Minnow — 4 to 5 in · Ghost shad or natural · 5/0 hook (Early morning, late evening, around eelgrass edges and creek transitions) Work with sharp rod snaps and long pauses, retrieve along weed edges, let it hang
Gambler Ace Wacky Rig — 4 in · Watermelon, green pumpkin, or natural · Match weight to depth and current, 1/16 to 1/8 oz (Morning through afternoon, transition times, around grass edges and hard-bottom edges) Rig through the middle, work with long soaks and micro hops, drag along edges
Creature Bait on Shaky Head — 3 to 3.5 in · Green pumpkin, junebug, or natural brown · 1/4 oz (Midday and late afternoon, around main-river points and channel edges) Drag slowly along hard bottom, work the shaking motion, fish tight to edges and transitions
Swim Jig with Creature Trailer — Jig 3/8 oz, trailer 3 in · Green pumpkin or junebug · 3/8 oz (Midday, along deeper weed lines and the grass edge in 6 to 9 feet) Swim it slow along weed edges, work the cover, pause near transitions
How to work it
Edge-oriented weed fishing — Early morning and late afternoon through dusk when largemouth stage to hunt. Less effective midday when fish pull away from edges. · Pool 7 and Pool 8 eelgrass complexes, backwater points where grass transitions to deeper water Work any transition where eelgrass meets open water or a deeper drop. Cast parallel to the edge, keep the bait in contact with the grass line, pause frequently. Don't fish the middle of the flat, fish the edge.
Topwater over grass in low light — Early morning before 8 AM and from 6 PM through dark. Wasting time midday in bright sun. · Eelgrass mats, duckweed pads, any shallow grass in the backwater complexes Walk a frog steady side to side or work a minnow-style topwater with sharp pops and pauses. Let the fish commit, don't overthink the cadence, and be ready for aggressive strikes.
Slow drag and pause on hard bottom — Morning through early afternoon, especially around the transition times when fish are staged but not fully aggressive. · Main-river points, channel swing edges, creek transitions into backwater points, anywhere hard bottom meets soft or deeper water Pitch a wacky rig, drop shot, or creature bait to a hard-bottom edge. Let it sit with micro-movements, then drag slowly across the transition. The pause between movements is where strikes happen.
Pro tips
If the pressure is rising and the sun stays clear, don't waste midday on the obvious shallow grass. The fish will back off and tuck to the first available shade or edge. Move to the 6 to 9 foot zone around channel swings and hard-bottom points where there's timber or a drop. Fish tight to structure.
The clearest water in the backwaters is at the upper ends of the complexes, behind the flows. If the main river and lower backwater mouths are stained from current or recent rain, lock through to Pool 7 or slide to the back of Lake Onalaska where the water filters first. That's where the frog bite and topwater will live.
If conditions change
If a front blows through and pressure rises further with clearing skies, the bite shuts down hard through midday. Pull out of the shallow flats and fish the thickest cover you can find in 8 to 12 feet. Drop the jerk minnow and frog, upsize to a 1/2-ounce creature bait or shaky head, slow everything down, and work the heaviest timber and weed mats foot by foot. If the water muddies from rain or higher flows, shift to vibration and displacement: spinnerbaits with a big Colorado blade in chartreuse, lipless cranks with a rattle, or a creature bait on a shaky head. Stay dark and loud. If clouds build and wind picks up from the south or west, the shallow bite extends longer than you'd expect. Push hard into the midday window on the eelgrass edges, topwater and jerk minnows stay live, and don't bail on the flats early.
