Brook trout in the Great Lakes are often called coasters. Brook trout mature at about 2 years of age and spawn in the fall. Lake-dwelling fish may spawn in streams or along the shoreline of lakes if spring seepage occurs. Occasionally, the lake outlet will be used for spawning. Nests are constructed by the female on gravelly bottoms of streams or lakes.
