The Iowa Great Lakes Water Safety Council, Inc is a not-for-profit public service organization formed to promote boating and water safety along with improved water quality on the Iowa Great Lakes. This chain of lakes is located in Dickinson County- Northwest Iowa.

The Iowa Great Lakes cover 12,700 acres with seventy miles of shoreline.

Five of the lakes (East Okoboji- West Okoboji, Lower Gar - Upper Gar, and Minnewashta) are connected so boats can travel between the lakes. Boats must pass under bridges to move between the lakes with clearance that varies from five to nine feet depending on lake water level.

The spillway between Big Spirit Lake and East Okoboji does not permit the passage of boats.



  • Contributions to promote water safety on the Iowa Great Lakes are welcome.

  • The WSC is a 501(c)(3) not-for profit corporation.

  • Contributions are tax deductible to the extent allowed by law.
