The Sioux County Dive Team is under the direction of the Sioux County Sheriff. This process began after the disappearance of four year old, Breiton Ackerman on May 22, 2005 in Willow Creek east of Alton, IA. Divers from many area teams participated in the search efforts, along with a few original Sioux County team members.
The Dive Team originated in 1979, and was operated under the Sioux County Civil Defense Department. After many years in existence the team started to drift apart. The Ackerman incident in 2005 started the efforts to revitalize the team. In the summer of 2007 the Sioux County Sheriff agreed to lead the team, providing a more consistent structure.
