Looked at the Willamette site and water temp in Portland is back up to 50F:
Water temp in Newberg up to 51.
I am not sure if I will do a trout/bass day at Hagg or a sturgeon/bass in the Willie tomorrow. The rising temps make the Willamette tempting. I don't think Hagg varies as quickly since it has such a small inflow and surface temp vs volume.
Last Saturday Hagg was still at 52.5F.
