The 2024 All Fish All Oklahoma Fly Fishing Challenge website is now Open and taking Registrations. That’s a mouth full for a tournament name, so it is affectionately referred to as the 15 x 15 Tournament because you have 15 weeks to catch 15 different species of fish. Please go to the tu420.com website and click on the orange button next to the 15×15 Tournament Challenge label. This will direct you to the Tournament’s website where you can read the rules, Register for the tournament, and pay your entry fee. Here, you will see when the tournament begins and when it ends.
