Washington County is fifth in the first tier of counties stretching west from the Missouri River. To the north lay Jefferson and Gage counties, Nebraska; east, Marshall County; south, Riley and Clay counties; west, Republic and Cloud. Washington County is embraced within that fertile territory which lies between the Blue and Republican rivers as they flow southeast into the Kansas River. The Little Blue River pays most particular attention to Washington County, draining, with its branches, all except its southwestern portions.
