Yellowstone Lake, a major feature of the national park but where native cut-throat trout are threatened by recently introduced lake trout. Behavioural traits of the two species are distinctly different. In late spring and early summer, cut-throats move from the lake to spawn in the shallow confines of the Yellowstone River and various tributaries where they are eaten by their natural predators. Lake trout, meanwhile, are fish that dwell and spawn in deep water, thus making them inaccessible to the animals that depend on cut-throat trout.
