Clackamas River (South Fork)

The South Fork of the Clackamas River is a tributary of the Clackamas River on the western slope of the Cascade Range in northwest Oregon. The 4.2-mile segment flows from its confluence with the East Fork of the South Fork of the Clackamas River and merges with Memaloose Creek to join the mainstem Clackamas River less than an hour's drive from Portland. As it flows through a narrow canyon with large rock outcrops and cliffs, a 100-foot waterfall in the lower part of the segment and old-growth trees along the river add to the visual diversity. Seasonally, deer and elk are in the area, and spotted owls and bald eagles also call the watershed home. Most of the watershed, filled with Pacific silver fir, Douglas fir and western hemlock, is under the care of the U.S. Forest Service.


Outstandingly Remarkable Values

Fisheries

There are small resident rainbow and cutthroat trout populations above the falls. Below the falls, spring chinook, winter and summer steelhead, fall run coho and a late winter run coho are found. The winter coho are a rare native stock of salmon originally found throughout the Columbia River drainage but now limited to the Clackamas River and its tributaries.

Recreational

This is one of the most remote large streams in the state. Trail uses include hiking, mountain biking, backpacking and access to catch-and-release fishing.
