S.D. Codified Laws § 7-7-12
The board of county commissioners shall establish, by resolution, the salary payable to the state's attorney. The salary payable may not be less than the following schedule as based upon the most recent decennial federal census of population for counties:
County Population | Salary Schedule |
Below 5,000 | $34,554 |
5,000 - 9,999 | $37,673 |
10,000 - 20,000 | $44,492 |
20,000 - 49,999 | $47,728 |
In counties of over fifty thousand population where a full-time state's attorney is required or in counties where the commissioners designate the position full-time the sum of seventy-one thousand five hundred thirty-four dollars per year. In counties of less than fifty thousand population the commissioners may designate the position full-time. The decision by the commissioners shall be adopted prior to the first day of January in the year of the election and may only be amended for that term of office with the consent of both the state's attorney and the commissioners. If no state's attorney is elected to the office at any general election, the board of county commissioners may contract for such legal services and negotiate the compensation therefor on terms and conditions determined by the board of county commissioners. The board of county commissioners may not decrease the salary of the state's attorney during consecutive terms of office of the state's attorney.
