Seasonal Patterns

🌿 Spring

Spring bass spawn heavily on the shallow northern flats and around downed timber, with pre-spawn fish actively feeding along weed lines in 8-15 feet of water. Expect aggressive strikes on crankbaits, jigs, and soft plastics as water temperatures rise through the 50s and 60s.

☀️ Summer

Summer fishing transitions to deeper weed edges, drop-offs, and rock formations where bass seek cooler water and shade. Early morning and evening topwater action is excellent near weed beds, while midday success comes from deeper presentations around structure.

🍂 Fall

Fall brings premium fishing as cooling water temperatures push bass back to shallow feeding zones along weed lines and rock reefs throughout the lake. Transition patterns create excellent opportunities for crankbaits and swimbaits targeting suspended and feeding bass.

❄️ Winter

Winter ice fishing can be productive for smallmouth and largemouth on deeper structure and holes in weed beds, though safety and ice conditions should always be monitored. Jigging with live minnows and small plastics around drop-offs and rocky points produces consistent winter success.
