• Tackle & Baits

  Public data does not answer the access question here. This is a natural basin, not a dammed one. Nothing formal is recorded here: no ramp, no car park, no marked path. A small crankbait along the drop and a worm in the thick stuff cover the bass. Where a permit is needed, the nearest town usually sells it. Fishing rules and camping rules are set separately here. If the gate is shut, Arden Lake at 1.8 km is the nearest alternative. Signs at Thompson Lake carry more weight than any list.
