It lies deep inside the county rather than near an edge.

• Tackle & Baits

  We have no record of the rules that apply 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. A small crankbait along the drop and a worm in the thick stuff cover the bass. Read any posted signs at the access point rather than assuming. Rules for boats are stricter than rules for the bank in many places. Should this one be busy, Patrickfalls Lake is 1 km off. Ask locally about Mason Lake if anything is unclear.
