Willow Creek is a river in Idaho, United States. It is about 84 miles (135 kilometers) long. This river is a tributary, which means it's a smaller stream that flows into a larger one. Willow Creek flows into the famous Snake River.
Exploring Willow Creek: An Idaho River
Willow Creek starts high up, about 6,568 feet (2,002 meters) above sea level. Its journey begins east of the Blackfoot Mountains in southeastern Bingham County. From there, it flows generally north into Bonneville County. Along its path, it passes by the town of Bone.
How Willow Creek Changes Course
South of the town of Ririe, Willow Creek meets a dam. This dam is called Ririe Dam. It blocks the creek's flow, creating a lake known as Ririe Reservoir. After the reservoir, the creek turns southwest. It flows between the towns of Iona and Ucon.
Later, Willow Creek splits into two smaller branches. This splitting is called bifurcating. The two branches are named North Fork Willow Creek and South Fork Willow Creek. They split at an elevation of about 4,777 feet (1,456 meters). Both of these branches eventually join the Snake River north of Idaho Falls.
Wildlife in Willow Creek
Willow Creek is home to many fish. It has a large number of brown trout. These fish are popular with anglers and are an important part of the creek's ecosystem.
