Santiam River ( North Fork) Above Detroit Lake - Lyons, OR

River Information

Fish Species: Rainbow Trout
The North Fork of the Santiam River above Detroit Lake, accessible near Lyons, Oregon, represents a pristine, high-elevation coldwater fishery. Distinct from the lower, dammed sections, this stretch offers a quintessential mountain stream angling experience, primarily focused on its indigenous wild trout populations within a clear, swift, and rocky environment.

The sole piscatorial objective is its robust population of wild rainbow (including redband) and cutthroat trout, alongside some brook trout in higher reaches. Anadromous fish are absent above Detroit Dam, affirming its status as a dedicated resident trout fishery. Angling techniques are expertly adapted to walk-and-wade, light-tackle approaches. Fly fishing predominates, leveraging highly effective nymph patterns and exceptional dry fly presentations during prolific insect hatches. Spin anglers achieve success with small spinners and spoons. Stealth and precise presentations are paramount due to the clear water and wary nature of wild trout. Optimal angling spans late spring through early fall. Access is primarily via Forest Service roads, facilitating wade-fishing. Regulations, meticulously managed by the Oregon Department of Fish and Wildlife (ODFW), are stringent, often mandating artificial lures/flies only, single barbless hooks, and encouraging catch-and-release. Adherence to current ODFW directives is unequivocally paramount for legal compliance and resource conservation.
