  • Weed edges in 8-10 foot depth range adjacent to spawning flats
  • Points and irregularities in the shoreline with submerged vegetation
  • Deeper vegetation areas near drop-offs for midday refuge
  • Swim Jigs worked through vegetation edges
  • Texas Rigs (Worming) for thorough coverage of transitional areas
  • Shallow Diving Crankbaits (0-6') along weed edges during active periods

  • Deep weed edges in 8-10 foot range
  • Shallow vegetation during early morning hours
  • Dock areas, especially those adjacent to deep water access
  • Drop Shot with 10-inch leader in deep weeds for bigger bass

  • Protected coves with deeper water access
  • Points and drop-offs adjacent to primary lake basin
  • Blade Baits worked slowly along deep weed edges and drop-offs
  • Ned Rigs fished with subtle movements near structure
  • Lipless Crankbaits slow-rolled through remaining vegetation
