About the nehalem river


The Nehalem River is a 119-mile-long river located in northwestern Oregon, USA. It is known for its pristine waters and rich salmon habitat.

The river is also home to several dams and reservoirs, including the Vernonia Reservoir, which was built in the 1950s for flood control and water storage. Recreation is also popular along the Nehalem River, with opportunities for fishing, kayaking, and hiking. The river and its surrounding watershed are protected by various conservation efforts to maintain water quality and support biodiversity.
