Lake Hartwell’s March bass madness

Upstate SC lake has great diversity

Brandon Cobb circles March on his calendar every year when it comes to Lake Hartwell. His confidence runs deep, and for good reason. He claimed victory here in the 2019 Bassmaster Elite Series, proving just how well he understands the fishery.

One of the biggest draws for Cobb in March is the variety. Depending on water temperatures and weather trends, anglers can encounter bass in every phase of the spawn.

“In March, you’ll find fish in pre-spawn, spawn, and even post-spawn toward the end of the month,” Cobb said. “That means different groups of bass are positioned in completely different areas of the lake.”

That range of seasonal stages mirrors Hartwell’s overall diversity. The lake supports strong populations of both largemouth and spotted bass, and while their habits can differ slightly, Cobb said anglers can often catch both species using the same techniques and lures.

“You’ve got that clear-water, spotted bass, deeper style of fishing,” he said. “But you also have hundreds of tributaries that can get stained, especially after the heavy rains we typically see in March.”

Clay-to-Rock Transitions

Among Cobb’s favorite March patterns is targeting clay banks that transition into rock inside creeks. These subtle changes in bottom composition can become bass magnets as fish move shallow.

“This time of year, bass will slide up and position on that rock,” he said. “When they do, those banks can absolutely load up.”

To tap into these concentrations, Cobb leans heavily on crankbaits. His strategy is straightforward: keep moving and cover water until he contacts a school.

“You’ve got to keep casting and moving until you run into them,” he said. “I like throwing fire tiger and crawdad patterns this time of year.”

Docks Deliver Big Bites

Hartwell’s shoreline is lined with floating docks, and Cobb considers them prime real estate during both the pre-spawn and spawn.

“Docks are good all year,” he said, “but they really shine during the spawn and pre-spawn.”

Because the docks float, bass often spawn beneath the walkways that connect them to shore. Others suspend and stage underneath the main platforms. To reach these fish, Cobb prefers skipping a wacky-rigged soft plastic worm far back under the cover—an approach that frequently produces some of the heaviest bass of the season.

Deep Roadbeds

While many fish push shallow in March, others remain offshore until the last moment. Submerged roadbeds in deeper water can hold bass feeding aggressively on blueback herring before they commit to the banks.

“They might be sitting in 35 feet of water,” Cobb said. “But when they’re ready, they can move from that depth to the bank in a single day.”

That combination of shallow and deep opportunities, clear and stained water, and multiple species makes March one of the most dynamic (and potentially rewarding) months of the year on Lake Hartwell.
