Whitewater is named for Whitewater Creek, which runs through town. The creek gets its name from the milky look of its water. A few miles to the south it runs into the Milk River, where the whitish coloring is even more pronounced. Whitewater is in the northern part of the county, sixteen miles from the Morgan port of entry into Canada. (from Cheney's Names on the Face of Montana, Mountain Press Publishing Company)
Whitewater is located south of the Canadian border and north of Sleeping Buffalo Rock and Bowdoin National Wildlife Refuge and is in the Milk River Valley.
