S.D. Codified Laws § 46-5-8
Any person desiring to make reasonable domestic use of water from any source may do so without obtaining a permit from the Water Management Board, except that no person may construct a dam across any dry-draw for any purpose, including domestic use, if the dam will impound more than twenty-five acre-feet of water, without first obtaining a permit from the board. Permits for dams on streams or dry-draws for domestic or other uses are subject to the doctrine of prior appropriation. Domestic users other than water distribution systems may register a domestic well with the board to document the location and output of their water supply and the quality of its water. The registration of a domestic well is not subject to the procedures for appropriation of water under chapters 46-5, 46-6, and the procedure contained in chapter 46-2A. The fee for registration is twenty-five dollars.
