About the owyhee river


The Owyhee River is a 346-mile-long (557 km) river that flows through Idaho, Oregon, and Nevada. The river was named after the Hawaiian fur trappers who worked in the area in the early 19th century. The Owyhee River basin is one of the least developed and most remote areas in the western United States. The river is fed by snowmelt and rainfall and is known for its steep canyons and rugged terrain. There are several reservoirs and dams along the river, including the Owyhee Dam, which creates Lake Owyhee, and the Unity Dam, which creates Unity Reservoir. These reservoirs are used for irrigation, flood control, and hydroelectric power generation. The Owyhee River is also a popular destination for fishing, kayaking, and rafting. The river flows through the Owyhee Canyonlands, which is home to a variety of wildlife, including bighorn sheep, golden eagles, and pronghorn antelope.
