I-Bass – West Lake Okoboji

On Saturday, July 25, 2026, the Iowa-based I-BASS tournament series returns to West Lake Okoboji for the second time in 2026—and this one feels even bigger.

That combination of big-bite potential and big-water decision making is exactly why this second Okoboji stop is one of the most highly anticipated events on the I-BASS schedule.
