Okamanpeedan Lake was explored by Joseph Nicollet during his 1838 expedition. He recognized the Sioux name for the lake, which means "nesting place of the herons", because of the large number of herons nesting in tall trees along its shores.[2] Calvin Tuttle was the first settler along the lake, thus that became another name for this body of water.[3]

Okamanpeedan's southwest shore is home to the Tuttle Lake Recreation Area, which includes sixty campsites and a boat launch.[4] Okamanpeedan State Park, maintained by the Iowa Department of Natural Resources, is located on the body's southeast shoreline.[5]

Fish found in Okamanpeedan Lake include walleye, northern pike, crappie, yellow perch, bullhead, catfish and American Grass carp.[6]
