SDCL § 40-23-20: Grazing permits to nonmembers.

The directors shall have power to grant to nonmembers grazing permits within such districts when the amount of forage within the district is greater than the need of the members, but no such permits shall be granted when such use shall be inconsistent with the terms of leases of county, state, or federal land within the district or with a safe policy of forage conservation within such district.
