We will gather again March 24-25, 2027 at Pokagon State Park in Angola, Indiana for our 38th annual conference!  This is a great way to meet other lake enthusiasts and water professionals while learning about lake management successes and challenges around the state.  This year the conference will be held on Wednesday and Thursday (instead of Thursday and Friday). Registration for the 2027 conference will open in December 2026.

New Indiana Law restricts wake boarding/surfing activities

Indiana House Bill 1062 (2026), passed as Public Law 154 on March 12.  In an effort to protect the shoreline and bottom structure of Indiana’s lakes this law restricts wake boarding and wake surfing on Indiana public freshwater lakes. It explicitly prohibits these activities between sunset and sunrise and bans wake boarding and wake surfing on lakes with 10 MPH speed limits, effective July 1, 2026. The law defines these activities and sets penalties for violations.
