Lake Okoboji, located in Dickinson County in the northwest corner of Iowa, is the bluest of the Iowa Great Lakes. It’s the second largest lake in Iowa, coming in behind Spirit Lake. Its maximum depth is 136 feet. This makes it the deepest lake in Iowa, and contributes to its deep blue hue.

For many years, Lake Okoboji has enjoyed the distinction of being called “one of only three blue water lakes in the world,” but we now understand that “blue water lake” isn’t a scientific distinction. Scientists and non-scientists agree that this Iowa lake’s sparkling sapphire water is worth a visit to northwest Iowa.
