The Necanicum River in Seaside

The Necanicum River is a river on the Pacific coast of northwest Oregon in the United States, approximately 21 miles (34 km) long. It drains a timber-producing area of the Northern Oregon Coast Range northwest of Portland. It forms the first estuary south of the mouth of the Columbia River along the Oregon Coast, reaching the Pacific Ocean at Seaside in Clatsop County.
