All uses of water in South Dakota, with the exception of domestic water uses, require a Water Right Permit. The Board of Water and Natural Resources has the authority to regulate and control the development, conservation, and allocation of the right to use the waters of the state according to the principles of beneficial use and priority of appropriation. Chapters 46-2A and 46-5 of the SD Codified Laws contain administrative procedures and requirements for water appropriation. Restrictions are placed on the obstruction of navigable watercourses, water use projects which may impair downstream water uses, and water diversions. Chapter 46-8 describes the circumstances in which the right of eminent domain may be used for application or conveyance of water for beneficial use.
