Jig (Casting & Pitching) 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 lead or tungsten head with a weed guard, skirt, and soft plastic trailer. Fished on the bottom by pitching, casting, or slow-rolling. The jig imitates crawfish and bottom-dwelling forage. More big bass have been caught on jigs than any other lure category — it's the lure that separates serious anglers.

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.
Jig (Casting & Pitching): Pre-spawn is prime season — pitch brown/green pumpkin jig to 45° bank transitions and rocky points.
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.
Jig (Casting & Pitching): Football jig on offshore ledges 15–30 feet. Swimming jig around grass edges at dawn.
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.
Jig (Casting & Pitching): Swim a jig around baitfish schools near points and flats. Shad trailer colors 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.
Jig (Casting & Pitching): Slowest presentation — drag a 3/8 oz football jig on deep hard bottom. Barely move it.
Best Conditions
All seasons, all depths, all cover types; most effective in 50–70°F water; excellent in pre-spawn and when fish are on hard bottom
Match trailer to conditions: craw trailer in cold water (slower fall, bigger profile), swimbait trailer when swimming, chunk trailer for flipping.
