Wow! Dejavu! I lived in Bend for 10 years and moved to Medford
The Rogue river is a wonderful steelhead river! You can fish ANY public access in the upper stretches and have a legit chance at steelhead 365 days a year. but you'll really want to focus your time from August thru November and February thru April. The Rogue will spoil you for steelhead. It can make any zero, a hero
The steelhead behave more like trout than any river in the NW. Yes, this means you can catch them with your trout techniques.
Then theres the Applegate
Smaller river, bigger steelhead!
Then theres Klamath Lake. This was my deepest love affair! Just over an hour to Rocky Point and trophy trout paradise! Right there is Williamson and wood rivers. Doesn't get much better for small river LARGE trout waters.
Not as many options as you have near Bend (Bend is a fly fishers paradise and I would move back there before I moved back to Medford) but Medford has some great options! You are a within striking distance of the Smith in Nor Cal, the Chetco, Windchuck, Elk, Sixes, Coquille, Umpqua.... Shall I go on?
