  Location of the mouth of the Middle Fork Willamette River in Oregon

The Middle Fork Willamette River is one of several forks that unite to form the Willamette River in the western part of the U.S. state of Oregon. It is approximately 115 mi (185 km) long,[3] draining an area of the mountains at the south end of the Willamette Valley south of Eugene.
Course
The Middle Fork Willamette River is formed in northeastern Douglas County by the joining of several small headwater streams near Emigrant Pass. It flows generally north, through the Calapooya Mountains, to the vicinity of Eugene, where it joins the Coast Fork Willamette River to form the Willamette River proper.
Just south, upriver, of Oakridge the Middle Fork is impounded in Hills Creek Reservoir, created by Hills Creek Dam. Downriver from the dam and Oakridge, the Middle Fork is joined by the North Fork Middle Fork Willamette River. Below this confluence, the Middle Fork is impounded by two more reservoirs, Lookout Point Reservoir and Dexter Reservoir, before joining the Coast Fork and forming the main Willamette River.
