Well I read the 2015 report so it wasn't Alton Baker that was stocked, it was Walter Wirth and Walling in Salem. Be careful; if you type in "odfw stocking report" into google, the south willamette watershed link will take you to the 2015 one! You have to click on the first link just straight to the odfw page.
Luckily I caught it last night right before I went to bed, so I just went north instead of south! Got skunked at both WW and Walling. Didn't see a single fish pulled out of either, as well. Might have just not been biting early when I got there... or maybe they both got fished out super fast.
