Lower Alsea River

The Lower Alsea River watershed, located in the Alsea River Basin, encompasses about 98,470 land acres of the western Oregon Coast Range mountains along the lower Alsea River in Benton and Lincoln counties. The watershed, with State Highway 34 running through it, stretches from Waldport on the coast to the inland town of Alsea. About 14% of the watershed (13,786 acres) is managed by the Bureau of Land Management (BLM) management, about 43% (42,342 acres) is managed by the United States Forest Service (USFS, Siuslaw National Forest), and the remaining land is in private ownership. The communities of Tidewater and Bayview are located within the watershed boundaries.
