 Of the 28 fish species present in the forest , 11 are not native and have been introduced by humans . Rainbow trout , chinook salmon , westslope cutthroat trout , bull trout , and mountain whitefish are all native to some of the forest 's waterways , while brook trout are a common invasive species that compete with the forest 's salmonids . The forest 's management indicator species is bull trout because they are sensitive to habitat changes and depend on specific habitat conditions . Sockeye salmon are native to the Salmon River watershed in the northern part of the forest , but dam construction on the Columbia and Snake rivers has hampered the migration of this anadromous fish and caused its population to collapse . Warm Lake supports the forest 's only native population of Kokanee salmon , the resident ( non @-@ migratory ) form of sockeye salmon . However , due to introductions by humans , Anderson Ranch , Arrowrock , Lucky Peak , and Deadwood reservoirs now support populations of Kokanee salmon . To provide additional recreational fishing opportunities , the Idaho Department of Fish and Game stocks several of the forest 's waterways with rainbow trout , while reservoirs are also stocked with Kokanee or chinook salmon and Lake Cascade is stocked with coho salmon and steelhead , the anadromous form of rainbow trout .
