The Deschutes River is a long river that meaders its way from south of Bend northward to the confluence with the Columiba River near Moody which is east of The Dalles. The Deschutes River is known for its rainbow trout and steelhead.
Typically, the long Deschutes River is divided into two sections for fly fishing, the Upper Deschutes River and the Lower Deshutes River. The Upper Deschutes section starts from the tailwater Wickiup Reservoir and runs north to Pelton Dam. The Upper Deschutes provides good fishing, as does the Little Deschutes River. Keep in mind that the stretch from Bend north to Lake Billy Chinook runs thin in the middle of the summer due to irrigation demands on the river (but other times you may find rainbow and brown trout here that are 14-16 inches).
Overall, Upper Deschutes River is the 4th most popular fly fishing river of all 22 fly fishing spots in Oregon.
