You can go to www.crappieusa.com, then go to the rules and read them. You can however launch anytime on Saturday Morning at Mississinewa, Salomonie, or Huntington. You can then start fishing at 6:30 AM and you have to stop fishing at 3:00 PM. You have to be in the weigh-in line before 4:00 PM, they close the line at 4:00 sharp. They will give the official time on Friday night at the Pre-tournament meeting. The ramp you choose and when you decide to get out is totally up to you. Just don't fish before 6:30 AM and make sure you stop by 3:00PM. Good luck to you.
I fished Patoka last Saturday, and have fished Crappie usa for a lot of years, the rules are pretty simple.
