You Must Certify Your Boat as Mussel-Free!


Requirement to certify your boat as mussel-free to participate in Mack Days
Recent discovery of zebra mussels in central Montana has elevated the need to reduce the risk of infestation in Flathead Lake. This is a very serious concern. Starting in 2017, all boats used in Mack Days must provide proof of certification from an authorized inspector before participation in the contest. Fish will not be accepted from anglers fishing from un-certified boats.

Pre-2017 Spring Mack Days Boat Inspection Arrangements
The first opportunity for boat inspections will begin about one month before the start of Spring Mack Days. There are multiple ways to obtain an inspection:

  1. Telephone Cindy Benson (883-2888 ext. 7294, or 270-3386) for an appointment at the Tribal Fisheries Office in Polson, 406 6th Ave. East, between the hours of 7:30 am and 4:30 pm, from Feb 13th to March 2nd
  2. At the Blue Bay Fisheries Building between the hours of 8:00 am and 4:30 pm, from March 6th to March 16th –calling for an appointment is not necessary but recommended
  3. At the Somers Boat Ramp between the hours of 8:00 am and 4:30 pm, on March 11th
We will be prepared with several inspectors at Blue Bay on March 16th and 17th for those who wish to wait until the contest begins to get their inspections. We remind all anglers that your boat must be inspected if you are fishing from a boat. We will not accept fish from boat-anglers who have not received an inspection from the Mack Days inspection sites or from a state inspection site before fishing that day.

We remind everyone that the Mack Days AIS Inspection does not replace the required state AIS boat inspection. Report any sightings to the National Hotline: 1-877-786-7267.
