About the beaverhead river

The Beaverhead River is a tributary of the Jefferson River in southwestern Montana, with a length of approximately 69 miles. It has a rich history, as it was a critical route for Native Americans and early explorers. Today, the river plays a vital role in agriculture, supporting crops like hay, wheat, and barley. It also supplies water to the reservoirs and dams, such as Clark Canyon Dam, which provides hydroelectric power and is a popular recreational spot. Additionally, the river is renowned for its fishing, particularly fly fishing for trout, and is a popular destination for anglers. The river's hydrology is impacted by snowmelt, rainfall, and diversions for irrigation, and it eventually joins the Missouri River.
