The Montana Ice Grand Slam is back for the 2026–2027 ice season, and sign-ups are open. It’s a multi-species tournament: your longest catch of each of 27 Montana fish species is measured in inches and added together, and the highest combined length wins. The season runs December 1st through March 31st, which gives you a full winter to work the list rather than pinning everything on one good day. It’s a format that rewards curiosity as much as skill — most of us fish the same few lakes for the same few fish, so a contest like this is a natural excuse to try water you’ve been meaning to check and species you’ve never thought much about.
Last year’s field was 30 anglers, and the top three took home $500 combined, which tells you this is still a genuinely approachable tournament where a good season can put you in the money. This year sign-ups are capped at 30 participants, and entry is $30 again, so if you’re interested it’s worth registering early. To sign up, download the Fish Donkey app and search for “Montana Ice Grand Slam.”
