Those named rivers and streams were among more than 15,000 nominations submitted by 2,500 Oregonians as part of Wyden’s statewide public effort to protect more of Oregon’s waterways and reduce catastrophic wildfire risks, improve drinking water and expand recreation access to boost rural jobs and economies.
