Fishing on the Clackamas in December has been a bit slow with low and cold conditions most of the month. Late summer steelhead have been nearly non-existent and the search for chrome winter fish is the game. Low and cold usually means lower in the river is best. Recent rains helped water temps bump up to 40 degrees from the mid-30’s with this last freshet. Look for early arrivers to be primarily below Eagle creek. The main component of Clackamas River Steelheading in December will be Eagle Creek stock. With low flows these fish are typically slowing in the Clack as very low flows on the creek limit movement in the creek itself.
If you decide to go best of luck out there!
