The fishing gets underway this morning at the 5th annual International Falls Bass Championship.
Sixty teams will fish either Rainy River or Rainy Lake today then switch bodies of water the next day.
President Gary Potter says water levels could be a factor for anglers.
"The river has thrown us a curve ball this summer," says Potter. "Everyone's wishing for more water in the river well this year they got it. It's about 8 feet higher than its ever been and the fish have changed position. The water's about a foot higher in the lake, at least a couple of feet, it's at the top of the rule curve and I think the fish have changed positions in the lake as well."
Weigh-ins at Smoky Bear Park begin at about 3 p.m. both days.
The Sioux Narrows team of Dave Bennett and Mike Salvador are the defending champions.
