Lyman County was created by the Dakota Territorial Legislature on January 8, 1873, but was not organized until May 21, 1893. Its boundaries were altered in 1891, 1897, 1898, and 1916.[3] The county was named for W. P. Lyman, a politician.[4]
Lyman County was created in 1873 and organized in 1893.[3] Oacoma served as its first county seat in 1891; in 1922 the seat was transferred to Kennebec.[5]
Lyman County is bordered on the north and east by the Missouri River, which flows southerly along its edge, and the western portion of its south line is also delineated by the White River, which then continued flowing eastward through the county's eastern area to discharge into the Missouri. Its upper central portion is drained by the Bad Horse Creek, which discharges into the Missouri near the midpoint of the county's north boundary.
The county terrain consists of rolling hills, sloping to the river drainages. Its area is largely devoted to agriculture.[6][7] The county has a total area of 1,707 square miles (4,420 km2), of which 1,642 square miles (4,250 km2) is land and 65 square miles (170 km2) (3.8%) is water.[8]
