- Do I need a fishing license to fish Swan Lake + Western District lakes?

The special regulations on this page change the bag, size, slot, or gear rules for Western District lakes; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Montana rules.
- Do Swan Lake + Western District lakes' special rules replace Montana's statewide limits?

Montana's statewide 2026 regulations apply on Western District lakes by default; the overlays above replace the matching statewide rule for the species or gear they name, while everything not specifically overridden still follows the statewide rule. When a water-body rule and the statewide rule disagree, the water-body rule wins.
