The Williamson River of south-central Oregon in the United States is about 100 miles (160 km) long.[8] It drains about 3,000 square miles (7,800 km2) east of the Cascade Range.[5] Together with its principal tributary, the Sprague River, it provides over half the inflow to Upper Klamath Lake,[5] the largest freshwater lake in Oregon.[9] The lake's outlet is the Link River, which flows into Lake Ewauna and the Klamath River.[9]
