The South Dakota Flood Information System (SDFIS) is always in an active development cycle with many experimental and advanced functionalities. The SDFIS, its functions, and all information are provided on an "as is" and "as available" basis.
Flood maps represent estimated extents of flood waters originating from the identified flood source(s) and are based upon stream geometry and infrastructure present at the time of creation. Maps are provisional and not intended for regulatory use.
