Seasonal Patterns

🌿 Spring

Spring spawning season (February-April) brings largemouth bass into shallow coves and flats, making this an excellent time for topwater and shallow-running crankbaits. Anglers targeting pre-spawn and spawn conditions find excellent success in the northern coves and creek channels.

☀️ Summer

Summer heat pushes bass deeper into the 40-60 foot zone, requiring jigs, drop shots, and deep-diving crankbaits to locate fish. Early morning and late evening bite windows are most productive, with topwater action occurring in low-light periods.

🍂 Fall

Fall cooling (September-November) triggers an aggressive bite as bass move toward shallower feeding zones and structure. Crankbaits, swimbaits, and vibrating jigs excel during this season as bass fatten up for winter.

❄️ Winter

Winter brings scattered but quality catches as bass move to deep water and slower presentations. Finesse tactics like drop shots and small jigs work best, with success concentrated near deep structure and the main channel.
