The Upper North Santiam is a winner from a few miles upstream of Marion Forks down to at least Pamelia Creek, if not all the way to Detroit Lake. Once that river takes on Pamelia and Whitewater Creeks it gets a lot bigger, but the fishing is still good and worth while. We held a Euro Nymphing clinic here a few days ago and the guys from the Central Coast Fly Club had a blast with Joey and Tonn.
