    The Soda Fork Creek project was designed by the Willamette National Forest Sweet Home Ranger District and the South Santiam Watershed Council to improve spawning habitat and stream complexity in Soda Fork Creek. The project involved pulling 34 large, live, stream-adjacent trees with root wads attached, into the stream channel. The total cost was $128,000, which included a large skidder outfitted with a 40,000 pound winch that pulled the trees into the water. Soda Fork Creek provides important spawning habitat for native fish species, such as the threatened winter steelhead. The habitat in the creek has been impacted by land use practices such as timber harvesting, road building, and active removal of large wood from the stream channel. The removal of large wood allowed the gravels to be washed away, leaving no spawning habitat. Threatened winter steelhead have not spawned in this stream for decades. This research looks at how dropping trees into the Soda Creek System changed stream conditions and whether these changes improved habit for native fish species.
