2018 Spring Mack Days Anglers:
Mack Days Fishing Events will continue to require that anglers have AIS Inspections prior to participating in the event. Proof of inspection will be required when you enter your fish or they will not be counted. Although Montana law does not require inspections for all boaters, we will continue the requirement for consistency and to be sure that Flathead Lake is protected. We are especially concerned about anglers from out of the Flathead Basin. The standard AIS Inspection Stations will not be open at the start of the event so our staff will conduct the inspections. We will try to be as accommodating as possible. Inspections can be arranged at our offices at 408 6
th Ave East in Polson during work hours starting February 26th. Please telephone 406-883-2888 ex. 7294 or 406-270-3384 to arrange a time. Inspections will be done at Blue Bay beginning March 13th. (Anglers can also call Kalispell and Thompson Falls MT Fish Wildlife & Parks offices for boat inspections.) Once Mack Days begins, we will do all inspections at Blue Bay. Please arrange times by calling 406-270-3386.
For inspections to go fast and smoothly, be sure your boat is clean, drained, and dry. No mud, dried plants, etc. in live wells, on lines, etc.
Thank you for your cooperation.

Requirement to certify your boat as mussel-free to participate in Mack Days
Recent discovery of invasive mussels in central Montana has elevated the need to reduce the risk of infestation in Flathead Lake. This is a very serious concern. Mack Days will not accept fish from boats that have not been inspected. You must provide proof of certification from an authorized inspector before your fish will be accepted in the contest (we will take entries but not fish).

Report any invasive mussel sightings to the National Hotline: 1-877-786-7267. 2018
