• Tackle & Baits

  Whether you may fish here is not something records settle. Access is unmapped, which usually means a farm track and a walk. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. A phone call first saves an afternoon. A polite question at the farm gate opens more banks than anything else. If the gate is shut, Guthrie Reservoir at 0.2 miles is the nearest alternative.
