Most salmonids (WSCT. bull trout, rainbow trout and brown trout) in the river system exhibit fluvial migratory life-history characteristics, whereas tributaries support both migratory and resident populations. WSCT have a basin-wide distribution and is the most abundant species in the upper reaches of the tributary system. Bull trout distribution extends from the mainstem Blackfoot River to headwaters of larger tributaries north of the Blackfoot River mainstem. However, juvenile bull trout will rear in smaller "non- spawning" tributaries, some of which are located in the Garnet Mountains. Rainbow trout distribution is limited to the Blackfoot River downstream of Nevada Creek and lower reaches of the lower river tributaries, with the exception of Nevada Creek upstream and downstream of Nevada Reservoir. Rainbow trout occupy -10% of the perennial streams in the Blackfoot watershed, with river populations reproducing primarily in the lower portions of larger south-flowing tributaries. Brown trout inhabit -15% of the perennial stream system with a distribution that extends from the Landers Fork down the length of the Blackfoot River and into the lower foothills of the tributary system. Brook trout are widely distributed in tributaries, but rare in the mainstem Blackfoot River below the Landers Fork.. Figure 7. Land ownership map of the Blackfoot River Watershed. 19.
