History of McKenzie County
The area that is now McKenzie County was first created on March 9, 1883. This happened when the government of Dakota Territory decided to form new counties. It was named after Alexander McKenzie, a well-known political figure at the time.
At first, the county was just a name on a map. It didn't have its own government right away. Over the years, its borders changed a few times. There were even plans to get rid of the county completely, but these plans didn't happen.
Finally, on April 20, 1905, McKenzie County officially set up its own government. This meant it could manage its own affairs.
The first main town, or county seat, was Alexander. Later, in 1907, the county seat moved to Schafer. In 1941, it moved again to its current location, Watford City.
Between 2010 and 2020, McKenzie County grew faster than any other county in the United States. Its population more than doubled! This big growth was mainly because of the oil boom in the Bakken Formation area.
Exploring McKenzie County's Geography
McKenzie County is located on the western side of North Dakota. Its western border touches the state of Montana.
The Missouri River flows along the northern part of the county. A large part of the Missouri River here is actually Lake Sakakawea, a big lake formed by a dam. The Yellowstone River also flows into the county from Montana and joins the Missouri River.
The Little Missouri River winds through the southern part of the county. It eventually flows into Lake Sakakawea.
The land in McKenzie County has rolling hills and river valleys. It's a mix of dry areas and places used for farming. The highest point is about 2,684 feet (818 meters) above sea level. McKenzie County is the largest county in North Dakota by land area.
The county has many different types of landscapes. You can find sugarbeet fields near the Missouri River. In the south, there are rugged badlands near the Little Missouri River. This is where parts of Theodore Roosevelt National Park and the Little Missouri National Grassland are located.
Between the two main rivers, there are large areas of prairie. These prairies can be gently rolling or have rocky, rough pastures. The southeastern part of the county is rich in wildlife. It also has groves of quaking aspen trees and bur oak trees.
Some parts of McKenzie County are in the Mountain Time Zone. Other parts are in the Central Time Zone. This means the time can be different depending on where you are in the county!
