Our Watershed Highlights:
We have some of the largest Oak prairie habitat in whole Willamette valley, the most remnant of what used to be there. Because these habitats are now rare in the valley, they are especially important to safeguard and enhance for future generations.
The GYW is one of the largest west-side tributary watersheds in the Upper Willamette River Valley. Hundreds of miles of our streams are designated by Oregon Department of Fish Wildlife as essential and/or critical habitat for imperiled winter steelhead trout. Studies conducted over the last five years estimate that the Yamhill River Watershed receives about 4% of the winter steelhead trout returning upstream of the Willamette Falls each year. In addition, studies conducted in 2009 and 2014 indicate that the Yamhill River Watershed may support the highest population of naturalized Coho salmon (38-48%) in the Upper Willamette River!!
