About this river

Greybull River

The Greybull River is a 90-mile-long tributary of the Bighorn River in northwestern Wyoming. The river is known for its scenic beauty and has been used for irrigation and agriculture since the early 1900s. The river flows through the Shoshone National Forest and the Bighorn Canyon National Recreation Area. It is a popular destination for recreational activities such as fishing, camping, and hiking. There are several reservoirs along the river, including the Yellowtail Dam which was built in the 1960s for hydroelectric power and flood control. The river is also important for irrigating farmland in the region. The Greybull River has a rich history, including being used as a transportation route for fur trappers and the site of a famous shootout between law enforcement and a notorious outlaw gang in the late 1800s.
