S.D. Codified Laws § 41-6-18.1
It is a Class 2 misdemeanor for a nonresident to hunt, take, or kill migratory waterfowl without a nonresident waterfowl license or a temporary nonresident waterfowl license, a migratory bird certification permit, and a federal migratory bird stamp, or in violation of the conditions of the licenses or the rules of the Game, Fish and Parks Commission.
A nonresident waterfowl license, except as otherwise provided in this title, entitles the licensee to hunt migratory waterfowl for two periods of five consecutive days.
Four dollars received from the sale of each nonresident waterfowl license shall be placed in the land acquisition and development fund. The moneys from this fund shall be used to acquire, by purchase or lease, real property to be used primarily for game production. This license shall be in such form as the Game, Fish and Parks Commission shall prescribe.
The provision in this section limiting the validity of a nonresident waterfowl license to two periods of five consecutive days does not apply in Union, Clay, Bon Homme, Yankton, and Charles Mix counties; and in such counties, the nonresident waterfowl license is valid during the same period as is a resident waterfowl license.
If the Game, Fish and Parks Commission allocates more than four thousand nonresident waterfowl licenses in a calendar year, any increase in the number of licenses allocated may not exceed five percent of the number of licenses allocated in the previous calendar year.
