Population assignment of entrained migratory Westslope Cutthroat Trout in North Idaho
… supported a robust metapopulation of Westslope Cutthroat Trout (WCT) Oncorhynchus clarkii lewisi, a western native salmonid of high cultural and economic value. The construction of impassible hydroelectric dams and smaller in-stream barriers has prevented the return of migratory WCT to …

Measuring the production of migratory Westslope Cutthroat Trout in tributaries to Priest River, Idaho
… is also, a significant contributor of migratory Westslope Cutthroat Trout Oncorhynchus clarkii lewisi (WCT) in the Clark- Fork Pend Oreille Basin (CFPOR). The goal of our study was to determine which tributaries to the lower Priest River are producing the most migratory WCT by locating their most …

Assessing the behavioral response of Westslope Cutthroat Trout to olfactory cues in a two-choice Y-maze
… which olfactory cues were most attractive to Westslope Cutthroat Trout Oncorhynchus clarkii lewisi (WCT) in a two-choice Y-maze. WCT used in this study were from Kings Lake and Paqua Creek in Pend Oreille County, Washington, and tested in 2018 and 2019. The different odorants tested in this …

MANAGEMENT AND LIFE HISTORY CONSEQUENCES OF HYBRIDIZATION BETWEEN WESTSLOPE CUTTHROAT TROUT (ONCORHYNCHUS CLARKII LEWISI) AND RAINBOW TROUT (ONCORHYNCHUS MYKISS)
… decline of native fishes cannot be overstated. Westslope cutthroat trout (<italic>Oncorhynchus clarkii lewisi</italic>, WCT) are a salmonid native to the northern Rocky Mountains. These trout hybridize with rainbow trout (<italic>O. mykiss, RBT</italic>) where they are sympatric; however, in …

Factors Influencing the Distribution of Bull Trout and Westslope Cutthroat Trout West of the Continental Divide in Glacier National Park
The reported decline of native bull trout Salvelinus confluentus and westslope cutthroat trout Oncorhynchus clarkii lewisi populations west of the Continental Divide in Glacier National Park (GNP) prompted research to identify critical habitats and investigate factors influencing their distribution …

Investigating the relationships between biotic and abiotic factors affecting migratory behavior in Westslope Cutthroat Trout within the Priest River System
… system as a significant contributor to migratory Westslope Cutthroat Trout (Oncorhynchus lewisi, WCT) in the Lake Pend Oreille and Priest River systems. Expanding on these results, we compared four Priest River tributaries that produced high proportions of migratory individuals (North Fork East …

Implications for Restoration: Effects of Riparian Vegetation and Shade on Temperature Gradients in Lower Gold Creek, Southwest Montana
… temperatures are high enough to damage critical westslope cutthroat trout populations. In summer 2011, the lower two miles of Gold Creek showed a greater than 1 F increase over the naturally occurring (reference) temperature, indicating possible stream temperature impairment. The heat flux model …
