TheCoast Fork Willamette River is one of two forks that unite to form theWillamette River in westernOregon in the United States. It is about 40 miles (64 km) long, draining an area of the mountains at the south end of theWillamette Valley south ofEugene.
The Coast Fork Willamette River is formed in southwesternLane County, in theCalapooya Mountains, by the confluence of theLittle River and theBig River. The Coast Fork flows north through the mountains, through theCottage Grove Lake reservoir, toCottage Grove, where it receives theRow River from the southeast. It continues north pastCreswell and joins theMiddle Fork from the south, about 2 miles (3 km) southeast of Eugene, to form the Willamette.
