You Must Certify your Boat as Mussel-Free

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. There will be inspections at the Somers boat ramp March 3rd from 9:00 till 4:00. 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.
