It is not a true trout but a char [6]. The species is also called mackinaw, togue, gray trout, and Great Lakes trout [4]. It has light spots on a dark body [4]. Lake trout inhabit deep lakes in the south and shallower lakes in the north [5]. They are commonly confused with true trout, but sources clarify they are char [6].
