@mijacques welcome to Oregon and OFF. Glad to have ya.
It's worthy to mention--since you mentioned trout--that nearly all streams are currently closed to trout fishing. So if you accidentally catch any while steelhead fishing; all trout must be returned unharmed into the water. Be sure to read the reg's for any stream, ahead of going out. Then ask questions if you have any. As Game Wardens/State Troopers EXPECT you to know the reg's BEFORE you hit the water. And will issue citations if you don't.
Lots of folks gravitate towards float fishing. But you can also effectively cover most all holding spots with spinners and spoons too. Spinners for the riffles, tail outs, etc. Spoons to bounce along into the deep pockets.
Rule of thumb for ANY of aforementioned methods...you have to get your OFFering, into the strike zone. So having your gear tick, tick, tick, tick along the bottom is where you want your spoon/spinner/bait.
Tight lines to you and send us some pics and reports!
