Frequently asked questions
- What special fishing regulations apply at Lake Mary Ronan?
- Lake Mary Ronan carries 2 special-regulation overlays that override Montana's statewide 2026 rules, covering Kokanee salmon and Northern pike. One of them reads: "10 / day (20 in possession); historic flagship MT kokanee water + long-time FWP statewide egg-take brood source (now shifting to Little Bitterroot Lake)." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Lake Mary Ronan?
- Yes. Lake Mary Ronan is in Montana, so a valid Montana fishing license is required just as it is anywhere else in the state, issued by Montana Fish, Wildlife & Parks (FWP). The special regulations on this page change the bag, size, slot, or gear rules for Lake Mary Ronan; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Montana rules.
- Do Lake Mary Ronan's special rules replace Montana's statewide limits?
- Only where they conflict. Montana's statewide 2026 regulations apply on Lake Mary Ronan by default; the overlays above replace the matching statewide rules 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.
- Which species have special rules on Lake Mary Ronan?
- Kokanee salmon and Northern pike have a water-body-specific rule on Lake Mary Ronan, each linking to its full Montana regulations above. Species not listed here follow the statewide Montana limits.
