Being a PDX local myself I don't like to commute a great distance from my home in Northeast Portland. The most I would drive to go fish is an hour. This creek is within that range and provides me good quality fish almost every trip.
Standing at the hatchery bridge, I spotted a few big fish immediately. They were schooled up in the deeper, slow moving parts of the stream. This gave me a sense of what to look for in the water when spotting fish in the future.
Lots of bright fish around and some medium looking fish too. Everyday we would walk down the stream into pools full of fresh Chinooks that were eager to eat a blue fox spinner or shrimps.
