North Fork Alsea River

The North Fork Alsea River Watershed is located in the central Coast Range (Coast Range Province) of western Oregon. It is approximately 17 miles southwest of Corvallis, and 26 miles east of the Pacific Ocean. Roughly 73% of the watershed is in Benton County; the remainder is in Lincoln County. The watershed is about 9 miles wide both east to west and north to south. A major tributary of the Alsea River, the North Fork Alsea River has a watershed of just under 41,900 acres (see Appendix 1, Map 1). After traveling some 15 miles, the North Fork Alsea joins the South Fork a few hundred yards west of the town of Alsea to form the mainstem Alsea River, which flows into Alsea Bay at Waldport.
