S.D. Codified Laws § 6-16-5
If the proposed district contains less than one thousand eligible voters as defined in § 6-16-6, the county auditor shall set a date, time, and location for a meeting to be held within the district, or at the county seat of any county in which a portion of the proposed district is located, to conduct an election on the question of formation of the special district. The date may not be more than sixty days after the appropriate board declares that the application for incorporation is valid. The auditor shall appoint three judges of election, one of whom shall serve as the superintendent, to conduct the election. The vote upon the question of incorporation shall be by ballot which conforms to a ballot for a statewide question except that the statement required to be printed on the ballot shall be prepared by the state's attorney. After the vote is cast and counted, the judges shall prepare a certification showing the whole number of ballots cast, together with the number voting for and the number voting against incorporation, and shall return the certification to the county auditor. If a majority, or if it is a water project district at least sixty percent, of the votes cast on the question of formation is in favor, an election shall be conducted by those present at the same meeting to elect the initial board of directors or trustees.
