What you see in that photo below is a hatchery springer trying to spawn in the lower McKenzie River.
That can be a problem for the last viable run of Upper Willamette Spring Chinook. So ODFW is doing something about it.
From ODFW: Last year more than 6,000 hatchery spring chinook returned to the McKenzie. Many of these fish bypassed the hatchery and spawned in the McKenzie River, impacting the McKenzie’s wild chinook, which are listed for protection under the federal Endangered Species Act. The Upper Willamette River Salmon and Steelhead Conservation and Recovery Plan limits the number of hatchery fish that are allowed to stray onto wild salmon spawning grounds in the McKenzie River. ODFW’s reallocation of 210,000 smolts from the McKenzie to the Coast Fork is part of a comprehensive effort to reduce the number of hatchery salmon spawning in the McKenzie River.
The agency is still releasing one million hatchery salmon smolts on top of a healthy wild run. But the fact that they are addressing this problem at all is encouraging.
