• Tackle & Baits

  Nothing we hold confirms whether access is permitted. It formed naturally, so levels move with rainfall rather than with a gate. There is no mapped parking or launch close by, which usually means walking in. State or provincial rules still apply whatever the bank status. Rules for boats are stricter than rules for the bank in many places. If the gate is shut, Lake on Three at 1.9 miles is the nearest alternative.
