Montana HB240 revises laws on digital mapping, hunting, and recreational use of navigable rivers and islands.

Montana HB240 mandates that all digital maps for electronic distribution must be updated by August 1, 2025, and then within 30 days of the annual state library update. It requires the state library to update its global information system map to reflect the current locations of navigable rivers and mark previous historical locations. The bill restricts recreational use of surface waters, prohibiting activities such as big game hunting, overnight camping, and placing permanent objects without landowner permission.
