S.D. Codified Laws § 46A-10A-56
All state public or school lands are subject to drainage laws. In any drainage proceeding affecting such lands, notices required by law to be given by publication and posting shall be served upon the commissioner of school and public lands at least thirty days before the time of the hearing. Such service may be made upon the commissioner in person, by service at the commissioner's office with the person in charge, or by registered or certified mail. If the land affected by the drainage proposal is not under the commissioner's control, the commissioner shall transmit a copy of the notice to the board or officer in charge of the land. The board or officer in charge of the land may appear at any such hearing or proceeding on behalf of the state.
