Did You Know?

Built in 1958, the park is named for Fred McCormick. McCormick worked for Idaho Power for 25 years and was chief engineer during construction. Oxbow got its name from a three-mile bend in the Snake River. To early settlers in the area, the bend in the river looked like the U-shaped frame that forms a collar around an ox’s neck.
