3 tops spots in the state (IMHO):
1. S. Oregon (obviously). The turkey capital of Oregon has got to be Douglas County. Higher density of bird there than anywhere else. Jackson and Josephine are increasingly worthwhile too. Problem is, much of the land is private and ranchers learned a while ago that they could charge saps a lot of money for access. You'll be hard pressed to just knock on doors and get access. You probably need to know someone, but if you do....oh man. The best hunting here is on agricultural lands. Hunting national forest land adjacent to open fields or private land can be very productive, but you have to really know your area.
2. White River - The game refuge on the east side of Mt. Hood is a very popular place to go for turkey. Almost all public and lots of birds. This is a rolling oak savanna, with deep canyons. Later in the season the birds work there way up the Cascades and you have to follow them up into the timber. Easiest to hunt early when the snow still has them concentrated down low in the open flats. You have to compete with a lot of other weekend warriors here, but if you're willing to hike you'll do fine.
3. Blue Mts. - The biggest toms I've killed seem to invariably come from the areas they are hunted the least. Funny huh? The Blue Mts. and Hells Canyon harbor large numbers of turkeys. Check openings in larger mature timber. Snow is a big factor here as the turkeys follow the snow-line as it receeds. One week they'll all be at a certain elevation and the next....nothing.
Timing: I like to go late april, early may. I've killed turkey on the opener and I've killed turkey towards the end of May. They'll respond to calls before and after the season so you really don't have to worry too much about timing. The heat of their "rut" though would probably be late April/early May. Hunting later is also a good idea because it ensures that the tom you take has had the opportunity to plant his seed before you take him home for supper. Just means more birds in the future!
So, this is the basics for turkey locations and times. Oh, and the Keno area around Klamath might have a few too.

Let me know if you need more specifics.
