The Okanogan River is a 115-mile-long river that flows through Okanogan County in Washington state. The river has a rich history, as it was an important trade route for Native American tribes and later became a center for gold mining. Today, the river is used for irrigation and hydroelectric power generation. The river's hydrology is heavily influenced by snowmelt from the nearby Cascade Mountains. The river is home to several reservoirs and dams, including the Enloe Dam, which generates electricity for the region. The river is also a popular destination for recreational activities such as fishing, camping, and rafting. Additionally, the river is used for agricultural purposes, such as irrigation for fruit orchards and hay farms.

Historical River Levels

The Okanogan River (known as the Okanagan River in Canada) is a tributary of the Columbia River, approximately 115 mi (185 km) long, in southern British Columbia and north central Washington. It drains a scenic plateau region called the Okanagan Country east of the Cascade Range and north and west of the Columbia, and also the Okanagan region of British Columbia. The Canadian portion of the river has been channelized since the mid-1950s.
