The 2026 Spring Mack Days fishing tournament is underway, with anglers catching over 5,100 lake trout. The competition runs until May 9th, featuring a chance to win tagged fish worth thousands.

The first week of the 2026 Spring Mack Days saw nearly 1,900 lake trout caught despite harsh winter conditions. The event supports fish conservation, enhancing native trout populations in Flathead Lake.

This week's Montana Outdoor Podcast features Ryker Bair and Patrick Casey discussing their experiences in Mack Days, highlighting the collaborative spirit among anglers as they share tips for successful fishing.

Mack Days returns to Flathead Lake March 12–May 9, 2026, giving anglers nine weeks to target non-native lake trout while supporting conservation of native bull trout and westslope cutthroat. Get the key dates, prize details, entry rules, fish drop-off locations, and important release and fish ID requirements.

On the hard water somewhere north of the border (possibly Canada), anglers haul a true monster lake trout through an ice hole—an ice-fishing moment that turns frozen fingers into a story for years.

The 2026 Spring Mack Days, sponsored by the Confederated Salish and Kootenai Tribes, runs from March 12 to May 9, focusing on conservation efforts while offering cash prizes for anglers.
