Topwater Popper Fishing on Lake Thurmond
Lake Thurmond · Georgia / South Carolina · Southeast
Lake Thurmond — federally known as J. Strom Thurmond Lake and locally called Clarks Hill — is one of the largest Corps of Engineers impoundments in the Southeast, covering roughly 71,000 surface acres on the Savannah River. The reservoir blends stained main-lake water with clearer upper creek arms, offering a diverse structural mix of submerged timber, clay points, main-channel ledges, and expansive flats. Largemouth bass dominate the sport fishery, with spotted bass and a trophy striped bass population adding variety throughout the year.
A floating hard bait with a concave face that produces a spitting, popping action when twitched. Most effective in low-light conditions near cover — points, dock edges, weed lines, and grass pockets. The pause after the pop is where most strikes happen. Few experiences in fishing match watching a largemouth explode on a popper.

Seasonal Tactics on Lake Thurmond
Lake: Pre-spawn largemouth push into the upper ends of creek arms and onto clay-bottomed flats in the 4–8 ft range as water climbs through the low 60s in late February and March. Shallow-running crankbaits and swimbaits along secondary points intercept staging fish before the full spawning push.
Topwater Popper: First light on spawning flats — fish hold shallow and crush surface baits. Slow cadence with long pauses.
Lake: Post-spawn bass scatter to main-lake points and channel ledges in 18–28 ft once surface temps push past 80°F. Deep structure fishing with football jigs and big swimbaits becomes the primary tactic, while topwater action over submerged timber produces in low-light windows on stained flats.
Topwater Popper: 30-minute window at dawn and dusk. Fish dock shade and grass pockets. Noon topwater dies.
Lake: Shad migrations pull bass shallow into the backs of creek arms from September through November. Schooling activity on the surface is common throughout October, and crankbaits matched to threadfin shad size — 2.5 to 3 inches — get eaten aggressively during the feed.
Topwater Popper: Extended feeding window as water cools. Fish can be caught on top all day in fall.
Lake: Cold-water largemouth consolidate on main-lake bluff edges and deep channel bends in 25–40 ft. Slow-rolled blade baits and finesse jigs in the 1/2 to 3/4 oz range account for the most consistent catches when water temps drop into the mid-40s.
Topwater Popper: Generally ineffective in water below 55°F — bass won't chase topwater in cold conditions.
Best Conditions
Dawn and dusk year-round, overcast days, calm to light-chop surface, spring through fall near cover and grass edges
Don't set the hook on the explosion — wait until you feel the fish pull the line. Half of all missed popper strikes are from anglers jerking too early.
