The primary river flowing through Central Oregon is the Deschutes River. Its source is Little Lava Lake in the Cascade Mountains, northwest of LaPine. The Deschutes runs south to north, eventually flowing into the Columbia River. Along its way, dams control its flow creating Crane Prairie Reservoir and Wickiup Reservoir. The river runs alongside the resort community of Sunriver and through the city of Bend. It is tapped as a water source for the Central Oregon Irrigation District which serves agricultural and municipal users. As the river continues north, it flows past the Eagle Crest Resort and the city of Redmond. North of Redmond, the Deschutes River has cut a deep canyon. West of Madras, Round Butte Dam impounds the Deschutes River, creating Lake Billy Chinook.
