Frequently asked questions
- What special fishing regulations apply at St. Marys River?
- St. Marys River carries 2 special-regulation overlays that override Michigan's statewide 2026 rules, covering Smallmouth bass and Muskellunge. One of them reads: "Statewide rule; Soo-area trophy fishery." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish St. Marys River?
- Yes. St. Marys River is in Michigan, so a valid Michigan fishing license is required just as it is anywhere else in the state, issued by Michigan Department of Natural Resources. The special regulations on this page change the bag, size, slot, or gear rules for St. Marys River; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Michigan rules.
- Do St. Marys River's special rules replace Michigan's statewide limits?
- Only where they conflict. Michigan's statewide 2026 regulations apply on St. Marys River 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.

- Smallmouth bass and Muskellunge have a water-body-specific rule on St. Marys River, each linking to its full Michigan regulations above. Species not listed here follow the statewide Michigan limits.
