History

Formed in 1909 from Jackson County, Meyer County, Washabaugh County, Pratt County and Lyman County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Mellette County was created from Jackson, Meyer, Washabaugh, and all of Pratt counties on June 3, 1909, and was initially attached to Lyman County for judicial purposes. It gained additional territory from Washabaugh County on March 2, 1911, and became fully organized and independent on May 31, 1911.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries.
