There's a story that says Owatonna got its name from a Native American princess who was cured of a serious illness after drinking water from the Straight River.

According to visitowatonna.org, "Chief Wabena heard of the curing waters called minnewaucan. His daughter, Princess Owatonna, was very frail so he moved his tribe to the site of the natural springs on the banks of Maple Creek. Princess Owatonna drank from the springs daily and recovered her health. Her kindly spirit hovers near the bubbling waters and beckons weary travelers to pause in the beautiful valley and drink of the magic waters."

A statue of Princess Owatonna now sits in Mineral Springs Park and apparently people travel from all over the region to taste the water.
