Monona County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 8,751.[1] The county seat is Onawa.[2][3]

History[]

The area around present-day Onawa was a stopping point in 1804 for Meriwether Lewis and William Clark during their exploration of the newly obtained Louisiana Purchase. Many years later, that site was memorialized as the Lewis and Clark State Park.[4]

Monona County was formed in 1851. It was perhaps named for an Indian word meaning "beautiful valley."[5]

When Ashton (originally called Bloomfield ) was named the county seat in the fall of 1854, a log house served as the first courthouse.[6] Ashton remained the county seat for only four years. That designation was moved to Onawa on April 5, 1858, and the first Monona County Courthouse was completed that same year.[7]

Politics[]

For over a century, Monona County was close to a national bellwether. Between 1900 & 2004, it only failed to back the national winner in 1960 & 1988. However, this bellwether status no longer applies. Barack Obama failed to carry the county in both of his electoral victories statewide & nationally, while Donald Trump in 2020 earned the highest percentage of any candidate in 100 years in spite of his unsuccessful reelection bid.
