![]() As a result of the extensive dredge mining, a complete re-channeling of lower portions of the Yankee Fork has occurred along with the deposition of extensive unconsolidated dredge piles. ![]() The mainstem YFSR has down-cut, causing upslope instability, also affecting many tributary streams. The altered stream corridor consists of unconsolidated and un-vegetated dredge tailings, which have increased sedimentation of spawning gravels and rearing pools. Approximately six miles of stream habitat on private land on the YFSR have been severely altered by dredge -mining (1938-1952), eliminating much of the natural meander pattern of the stream and associated in-stream habitat, and riparian vegetation and function. The Yankee Fork Restoration Project is working to improve floodplain/riparian zones along the dredge sections of the Yankee Fork Salmon River (YFSR). ![]() Restoring the YFSR, historically a major Chinook salmon producer, to natural conditions will create a healthy, functioning riparian community providing numerous benefits to fish and wildlife. The goal of the Yankee Fork Dredge Tailings Restoration Project is to restore natural river channel characteristics, floodplain function, hydraulic and sediment regimes, and aquatic habitat within the dredged reach of the YFSR, initially by redistributing dredge tailings piles from the floodplain.
