Diamond Fork Meadows is a 275-acre wetland meadow within the middle reaches of Diamond Fork Creek, a tributary of the Klickitat River. The meadows are bounded by Darland Mountain to the north and the Goat Rock Range to the Northwest. There are approximately 4.5 miles of stream channel within the Diamond Fork Meadows project area. Diamond Fork Meadows lies within Tract "D" of the Yakima Indian Nation Reservation. The area has experienced considerable logging and associated road construction. A major source of wetland degradation has been from livestock grazing. Grazing, along with timber harvest and road construction has led to the concentration of stream energy in new channels made up of unstable silt, sand and small gravel deposits causing downcutting and straightening of the stream. The stream wears away at high, confining banks, transports fine sediment out of the meadow and leaves gravel deposits within an increasingly broad channel. Livestock widen the channel further by trampling banks. Pools are infrequent, and average water depth is less than one foot in summer. Project elements include restoration of fish habitat in upper Diamond Fork Creek, creating pools and providing bank cover in meadow areas mostly by allowing natural aggradation processes to take place. Rehabilitation includes exclusion of livestock (fencing), stabilization of streambanks and making the channel narrower and higher by trapping sediment from upstream.
