Gurgler (Bass) (Chartreuse/White)
As spring progresses and water temperatures warm, topwater action intensifies. This popper creates an enticing disturbance, drawing explosive strikes from bass, sunfish, and even gar in calmer pockets.
Elk Hair Caddis
Late spring marks increased caddis activity. This general caddis adult imitation is excellent for opportunistic feeders among the target species when caddis are active on the surface.
