History of Washington County

Washington County is in eastern Nebraska, right next to the Missouri River. European explorers first visited this area around 1739. These were French explorers named Pierre Antoine and Paul Mallet. They were on a trip to trap animals for their fur.

Early Explorers and Forts

In 1804, famous explorers Lewis and Clark came through. They met with Native American chiefs near where Fort Calhoun is today. They told the chiefs about the new United States government. Because of this meeting, Fort Atkinson was built in 1819. It was a very important outpost in the middle of the country until 1827.

County Formation and Growth

The first permanent settlement in Washington County started in 1854. In the same year, Washington County became one of the first eight counties in Nebraska. It was officially set up again in 1855. The county seat, which is the main town for government, has moved a few times. It was first in Fort Calhoun, then DeSoto, and since 1869, it has been in Blair.

Past Power and Missile Sites

South of Blair, there used to be a power plant called the Fort Calhoun Nuclear Generating Station. It was the smallest nuclear power plant in North America. It closed down in 2016. Also, an old Atlas missile launch site was located east of Arlington. It was part of Offutt Air Force Base but was stopped being used in the 1960s.
