Iowa Code § 469A.8
The state may take possession of a dam for which a permit has been issued under section 455B.275 through receivership proceedings, if the dam becomes owned, leased, trusteed, possessed, or controlled by a person in a manner constituting an unlawful combination or trust, or if the dam is the subject or part of the subject of an agreement to limit the output of hydraulic or hydroelectric power derived from the dam for the purpose of price fixing. The receivership proceedings must be instituted by the executive council, and shall be conducted for the purpose of disposing of the dam for a lawful use. The proceeds from the disposition shall be used to reimburse the state for expenses incurred in the receivership. The remaining proceeds shall be awarded to persons found by the court to be entitled to the proceeds.
