On November 4, 2014 two thirds of Shannon County voted to change the name of the county to Oglala Lakota County. This name change was then passed by House Joint Resolution 1005 in the 2015 Legislative Session. May 1st, 2015 was declared the official renaming day.
The Shannon County offices will be spending the next month changing names on their website as well as official documents in anticipation of the May 1st change.
