The South Fork Salmon River is a tributary of the Salmon River in Clackamas County in the U.S. state of Oregon. Arising near Plaza Lake, it flows generally northeast along the east side of Salmon Mountain to meet the Salmon 11miles upstream of the larger stream's confluence with the Sandy River at Brightwood.[3]
The entire South Fork lies within the Salmon-Huckleberry Wilderness, which is part of Mount Hood National Forest. The South Fork's only named tributary is Mack Hall Creek, which enters from the right.[3]
Green Canyon Campground, about 4miles by road from Wemme, is along the Salmon River about a mile downstream of the mouth of the South Fork. Open from late May to late September, the campground has sites for tents and recreational vehicles (RV)s, picnic tables, and access to hiking trails and trout fishing.[4]
