• Tackle & Baits

  No public source sets out the position on this bank. This is a natural basin, not a dammed one. Access points are not mapped for this water, which suits people who like quiet. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Look for a notice board at the entrance. A polite question at the farm gate opens more banks than anything else. Lac Eddy sits 1.2 km off and takes the overflow. For Lac Sourus, the notice at the access point is the final word.
