I just moved from Portland to Idaho. While we lived in OR for 4 years, we did Search and Rescue with Nara through Search ONE K-9 Detection down in Tualatin. They focus on a lot of obedience and nose work for air scent, cadaver, tracking/trailing, etc. I was also a member of the Cascade Sled Dog Club with my 2 huskies. Even Nara, my GSD, would go bikejoring (think sled dogs pulling you on a bike or dog scooter instead of a sled for when there is no snow) with us to get the exercise needed for SAR and just general maintenance and overall health. Not sure what other types of groups you're interested in. I'm sure there are all sorts of dog sports in that area. If I can think of other ones, I'll let you know. Hope that helps.
