S.D. Codified Laws § 5-5-22
In offering any land for leasing or at any time after the lease has been made, the commissioner of school and public lands may grant to any lessee of land under the provisions of this chapter a permit to erect thereon such buildings, corrals, fences, and well apparatus as may be necessary to fully carry out the purposes of the lease, and such lessee may remove such improvements as are capable of removal without damage to the land at any time before the expiration of the term or upon cancellation of the lease, and during a period of sixty days from the date upon which such land is offered for releasing or sale, and may sink such wells and construct such dams thereon as may be necessary, the cost of which may not exceed an amount agreed upon by the commissioner. In addition, the commissioner of school and public lands may grant in like manner a permit to prepare the ground and to plant shelter belts on such land, and to perform government approved ripping, furrowing, contouring, and reseeding. However, the lessee shall notify the county auditor and the commissioner of school and public lands in writing whenever any such improvements are placed upon such lands. In no event is the state liable for any material furnished for, nor for any labor performed on, such improvements.
