Seasonal Patterns

🌿 Spring

Spring brings aggressive feeding as bass move to shallow coves and spawning areas near main lake creek channels. Crankbaits, spinnerbaits, and topwater lures produce well as water temperatures warm into the 50s and 60s.

☀️ Summer

Summer bass retreat to deeper structure, main lake points, and rocky ledges where cooler water provides relief. Offshore fishing with drop shots, Carolina rigs, and deep-diving crankbaits near the dam and creek channels becomes most effective.

🍂 Fall

Fall migration patterns push bass into mid-depth zones and along the main creek channel where baitfish congregate. Shad-pattern crankbaits, swimbaits, and soft plastics work well as bass feed heavily before winter.

❄️ Winter

Winter bass slow considerably but remain catchable near deeper holes and the main channel. Slow presentations with jigging spoons, drop shots, and small soft plastics near structure produce the most consistent results in cold water.
