Instream-Flow Needs For Anadromous Salmonids And Lamprey On The Pacific Coast, With Special Reference To The Pacific Southwest

摘要: This paper addresses differences in instream-flow needs (IFNs) of Pacific salmonids and lamprey across species, life stages, stream sizes on the coast, with additional consideration salmonid-IFN data from northern Europe. The Southwest set was for various stages coho salmon steelhead trout small coastal streams central southern California. These showed that younger required less flow than adults. Northwest spawning adults all five species Washington or more flow, relative to mean annual smaller streams. Although these IFNs varied by were much higher protect wetted perimeters (rearing habitat) water quality high-flow guild included chinook, pink, chum salmon, whereas low-flow sockeye salmon. Steelhead unique showing relatively high creeks rivers, unlike large such affected size this
