The fishery

J. Strom Thurmond (Clarks Hill) is a 71,100-acre USACE reservoir on the Savannah River at the GA/SC line, held at a 330-ft full pool with roughly 1,200 miles of shoreline. The lake splits into two major arms: the Georgia Little River arm to the west and the main Savannah River arm running north, joining near the dam and the Keg Creek confluence. Since blueback herring were introduced, the bass fishery has shifted to an open-water, herring-chasing pattern - fish live deep in summer and winter and roam offshore points, humps, and 'islands' rather than the bank except during the spawn. Classic structure includes long parallel underwater points, submerged humps and shoals, standing timber and brush in creek arms, and rocky mid-lake points that hold spotted bass. Seasonally: prespawn and spawn (Feb-Apr) pull largemouth into Little River creeks (Grays, Lloyds, Rousseau); summer and fall bring schooling topwater blowups over offshore structure at dawn as bass and hybrids corral herring, and spoons or drop shots work the 25-40 ft range midday.

SAMPLE GUIDE REPORT · TUESDAY, SEPTEMBER 15, 2026

Fall transition firing up - work the channel swings and points as bait pushes out of creeks.

WATER 73°FAIR 76°FWIND 8 MPH ENESEASON FALLPOOL -3.9 FT

We're in full fall pattern now. Water's dropped into the low 70s, right where bass start bunching up and chasing bait off the structure hard. Pressure's rising after a small drop, so don't expect the aggressive pre-weather bite, but the cooler water and falling pool have bass thinking about migration. The lake's still down about 4 feet, which shallows everything on your map. Main lake points and channel swings are starting to concentrate fish as herring and shad move out of the creek arms toward deeper water. If the sun burns through the clouds, they'll slide out to 18-25 feet by mid-day, but early and late they're looking up in the 10-15 foot zone. The bite's solid right now because the water temperature is in that sweet spot where bass feed hard but aren't panicked by heat.

The day's game plan

EARLY MORNING · 7:13 AM to 9:30 AM
Main-lake points and channel swings in 12-18 feet, particularly the breaks where structure meets deep water
Rapala DT10 crankbait in shad colors, or a 4-inch Zoom Super Fluke in herring pattern on a 1/8-ounce jighead. Throw long casts and work the bait through the 12-15 foot band with a steady, shallow-running retrieve for the crankbait or a glide-and-fall cadence for the fluke. Cover water.
First light is when bass are still feeding shallow after the night before. Herring are starting to move out of the creeks and bait concentrates on these transitions. The minor solunar at 4:55 PM yesterday set them up, and this window carries momentum. Work it fast while the light is low.
MORNING · 9:30 AM to 12:00 PM
Deeper channel structure and offshore humps in 18-25 feet, with priority on spots where brush or rock sits on the high point
3/4-ounce football jig in peanut-butter-and-jelly or brown-orange, dragged slow right on the bottom. Cast up shallow and drag it down the slope, working the cover methodically. Follow up any fish that blow off with a secondary cast.
Once the sun climbs and pressure stabilizes, bass slide out to their daytime zone. With water still cool enough to hold fish deeper without stress, they'll stack on structure. The lake down 4 feet means your electronics show fish shallower than the map; trust what you see on sonar, not the contours.
MIDDAY · 12:00 PM to 3:00 PM
Same deeper structure and brushpiles, 20-25 feet, or rocky points with good bottom definition
Zoom Trick Worm or a 5-inch Zoom Ol' Monster in junebug or watermelon-red, rigged Texas-style on a 1/2-ounce tungsten weight. Pitch it tight to brush or rock and work it slowly with a dragging action, letting it settle into the thickest cover.
Midday bite is slowest, but the water's clear enough to see movement and cool enough that bass haven't pulled into the thickest cover to hide. Finesse and patience beat speed. If you have sonar, mark the exact brush clumps and stay vertical on them rather than casting blind.
LATE AFTERNOON · 3:00 PM to 5:30 PM
Channel swings and the inside bends of creek arms where they meet the main lake, 15-20 feet
Same jig as the morning rotation, or switch to a jerkbait like a Rapala Shadow Rap in silver-black or pearl. Work the jerkbait with sharp, 2-3 inch twitches and longer pauses. Let it fall on slack line between jerks.
As the afternoon heat eases, bass begin sliding back shallower and toward the creeks where bait is staging. The solunar major fires at 4:55 PM, so this window should have increased activity. Jerkbaits trigger reaction strikes in transitional areas where structure changes sharply.
EVENING · 5:30 PM to 7:00 PM
Creek-arm points, secondary points, and any rock or wood structure in 8-15 feet inside the creeks
Chrome or silver topwater walker like a 3.5-inch Crock-O-Gator or Heddon Zara Spook in black or pearl. Work it steady with slight twitches, covering shoreline structure and any visible baitfish activity. Speed up slightly if you see shad schooling.
The solunar major at 4:55 PM aligns with cooling light, and bass move shallow to feed on bait being pushed into the creeks. Topwater draws surface strikes and lets you cover a lot of water fast. The slight cloud cover keeps them looking up longer than a bluebird day would.
DUSK · 7:00 PM to 7:35 PM
Shallow flats and pocket edges inside creeks, 6-12 feet, anywhere cover meets open water
Greenfish Tackle buzzbait in white or black, or a Zoom Horny Toad in green pumpkin. Run the buzzbait fast past any stick, rock, or tree. Fish the toad with a slow crawl, letting it pause over cover.
Last light before dark is prime feeding time. Bass move into pockets and chase bait hard. The reduced light and cooling water drop their guard. This is when you can cover a lot of water with a buzzbait and pick up a kicker or two before the bite dies.
NIGHT · 7:35 PM to midnight
Same pocket structure and shallow creek areas, 6-12 feet, but focus tighter on the thickest cover and deepest pockets
If you want to fish it, stick with a buzzbait in black, running it slow and methodically past cover. Alternatively, soak a live bluegill or shiner on a simple slip-rig 2 feet under a bobber over deep pockets. Most anglers leave the water, but night fishing for a lurker is an option if you stay mobile.
Topwater and moving baits work in low light, but as darkness sets in, bass become less predictable. If the moon comes up, a buzzbait can still produce. Most of your good day happens before sunset, so don't waste energy here unless you want to hunt one big fish.

Pro tips

If conditions change

If a cold front blows in and pressure keeps rising, the bite shuts down hard. Scale back to finesse: drop to 3-inch worms and drop-shot rigs around the thickest cover. Fish slow and tight. Move less and spend more time on individual pieces of cover. If wind picks up out of the north, the shallow creek bite dies but the main-lake structure becomes more productive because wind-blown banks hold oxygen and disoriented bait. If creeks get stained from run-off, shift colors to dark or bright contrast: black, junebug, or white. Buzzbaits and chatterbaits work better than finesse in stained water. If the water clears dramatically, downsize everything and use natural colors. Switch from a 4-inch fluke to a 3-inch and add a fluorocarbon leader because visibility is high and bass will see braid.
