I honestly wouldnt fish the Rogue for trout unless you are fly fishing, or fishing above lost creek lake. Most fish you will catch will be smolts and might look like trout but arnt. If you want some places that are good for keeping trout around the area ill name a few, Hyatt, Howard Prarie, Lost Creek Res, Willow Lake, Medco Pond, Emigrant lake.
If you get your steelhead tags i wouldnt mind showing you some stuff on how to catch steelhead. Its really not as hard as some make it out to be
Mad Dog. Im pretty sure they stopped stocking trout beneath the dam. So the only trout you'll catch will be wild. or steelhead or steelhead smolts.
PS> If its over 16inches below the dam. its considered a steelhead and must be tagged or released. If you fish the rogue you'll run into a lot of fish this size, they are called Half Pounders. Fun to catch on lite gear.
