SDCL § 46-5-31.1: Abandoned permitted irrigation use--Stock watering permitted.

If permitted irrigation use from a storage dam is abandoned or forfeited but the storage dam is used for stock watering, stock watering may be added to the license or permit upon the request of the permit or license holder. A license or permit modified under this section retains the priority date of the original license or permit. This addition of stock watering to the license or permit may occur without application or publication pursuant to § 46-2A-4, if no diversion is made from the stock dam and the chief engineer makes a finding that existing water rights will not be impaired.
