Phase-by-phase

Pre-Spawn

Trophy fishing window
53–57°F

Spotted bass stage on rocky points and steep banks in 10–25 ft as water temperatures climb through the low 50s. They occupy deeper water than largemouth during pre-spawn.

Target rocky points and bluff banks with deep-running crankbaits and jigs.

Spawn

Conservation window
57–74°F (peak 63–68°F)

Active spawning behavior. Males construct nests on hard bottom in deeper water than largemouth typically use — often 6–12 ft. Spawn timing slightly earlier than largemouth in shared waters.

Spotted bass populations have replaced or hybridized with native bass species in some Western waters; some states encourage harvest of spots in non-native waters during spawn for population control ra

Conservation context

Spotted bass populations have replaced or hybridized with native bass species in some Western waters; some states encourage harvest of spots in non-native waters during spawn for population control rather than the traditional release-on-bed practice.

Post-Spawn

Recovery feeding
74–82°F (~12 days)

Post-spawn spotted bass return to structure-oriented summer patterns more quickly than largemouth — they spend less time in shallow recovery zones.

Drop-shot and shaky head presentations on deep structure produce post-spawn spotted bass.

Summer Pattern

Standard patterns
Above 82°F

Fish disperse to summer habitat and feeding patterns. Spawn cycle complete until following year.

Standard summer fishing tactics apply.
