The Deschutes River is a major tributary to the Columbia River, running over 250 miles from its source in the Cascade Mountains to the Columbia River Gorge. The river has a rich history, with Indigenous peoples using the river for fishing and transportation for thousands of years. European explorers and settlers later used the river for transportation, trade, and agriculture.

Hydrologically, the river is fed by both snowmelt and springs, and is regulated by a number of dams, including the Pelton Round Butte Dam Complex. The complex includes the Round Butte Dam, which creates Lake Billy Chinook, a popular recreational area for boating, fishing, and camping.

The Deschutes River provides irrigation water for agriculture in the region, and also supports a thriving recreational industry, with activities such as whitewater rafting, fishing, and hiking. It is home to a number of fish species, including steelhead and salmon, which have faced challenges due to the construction of dams and other human impacts on the river.
