Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Spring largemouth bass concentrate at Weed flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Weed flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (19 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
