Three-line fishing in the Mississippi and St. Croix Rivers permission

SF 2624 would amend Minnesota law to permit anglers to use up to three fishing lines in the Mississippi River and St. Croix River, replacing the current two-line limit in those waterways. This change would directly affect recreational fishermen who fish in these rivers, allowing them to use an additional line without needing special permits. The amendment updates Minnesota Statutes section 97C.315 by adding a new exception for three lines in the specified rivers, while maintaining existing limits elsewhere. This is a straightforward policy adjustment to fishing regulations, not a broader environmental or conservation measure.
