McLean County, North Dakota

McLean County is a county in the U.S. state of North Dakota. As of the 2020 census, the population was 9,771. Its county seat is Washburn.

History
The Dakota Territory legislature created the county on March 8, 1883, with areas partitioned from Burleigh, Sheridan, and (now-extinct) Stevens counties. The county was named for John A. McLean, the first mayor of Bismarck. The county organization was completed on November 1 of that year. Its boundaries were altered in 1885, in 1892, and in 1908. It has retained its current configuration since November 3, 1908, when a portion of its previous territory was partitioned to recreate Sheridan County (Sheridan had been dissolved on November 8, 1892, with its territory annexed to McLean).

Geography
The county's western boundary is delineated by Lake Sakakawea, created in 1956 by construction of Garrison Dam at the county's southwestern edge. The southwestern boundary of the county is delineated by the Missouri River as it continues its southeastward flow from the lake. The county terrain consists of rolling hills, dotted with lakes and ponds in its eastern portion. The area is largely devoted to agriculture. The terrain slopes to the south and east, with its highest point on the north boundary line near its NW corner, at 2,201 ft ASL. The county has a total area of 2328 sqmi, of which 2111 sqmi is land and 217 sqmi (9.3%) is water. It is the third-largest county in North Dakota by land area and second-largest by total area.
