Decades of forest harvesting have significantly impacted the Eve River watershed and the anadromous fish species that rely on this waterway. Anadromous populations of Chinook (Oncorhynchus tshawytsha), Coho (Oncorhynchus kisutch), Chum (Oncorhynchus keta), Pink (Oncorhynchus gorbuscha), Sockeye (Oncorhynchus nerka), Steelhead (Oncorhynchus clarki ), Cutthroat (Salmo clarki), Dolly Varden (Salvelinus malma) char, and resident Rainbow (Oncorhynchus mykiss), Cutthroat and, Brown Trout (Salmo trutta) are well documented within the watershed.
Harvesting has resulted in increased peak flows, decreased bank stability and signficant erosion and sedimentation. These effects are negatively impacting fish production in this channel by reducing the availability of high quality rearing and over-wintering habitats and smothering spawning beds.
In the study area, a major oxbow has formed since the river started changing its course in the 1960?s. This channel section was identified as a significant concern to fisheries due to the rapid loss of bank material into the river (>1m/yr) and its negative impacts on fish and fish habitat.
