The South Fork Roaring River is a 4.6miles tributary of the Roaring River in Clackamas County in the U.S. state of Oregon.[1] Beginning at Rock Lakes in the Mount Hood National Forest in the Cascade Range, it flows generally northwest along the base of Indian Ridge to meet the main stem.[4] The South Fork has no named tributaries.[4]
In 2009, the entire river was added to the National Wild and Scenic Rivers System. Designated "wild", its watershed includes old-growth forest, a deeply incised canyon, and many cascades, and provides prime habitat for northern spotted owls.[1]
The watershed is part of the Roaring River Wilderness,[1] a 36500acres federally protected area also established in 2009. The area is off-limits to commercial logging and mechanized recreation though still open to fishing, camping, hunting, hiking, and many other activities.[5]
