The upper Rogue River near Medford has trout, salmon and steelhead in it this time of year. Also Diamond Lake is about 1.5 hours away and is some of the best still water trout fishing in Oregon! Good luck!
Your rod will be fine, its your tippet you need to rethink. With that current a 12" fish feels like the Steelhead of a lifetime...great place to spend a year or two..
