(first post and yes I know this is an older thread) I live on Marys River above Wren and my 8yo girl catches trout quite often. They're not big, but definitely legal. Between crawdads and trout, she catches her own dinner pretty often. There are a few bridges where people could fish, but it's mostly private property above Philomath. The water is very clear and plenty of shallow rocky areas mixed with deeper pools. There are 5 bridges on Harris road, and plenty of Starker owned land you can get permission to use for free. It's rugged terrain, but you could follow the tracks for a real "Stand By Me" experience.
