This photo of brook trout was taken by Jim Johnson. Brook trout are a member of the salmon family and are unique because they have no teeth on the roof of their mouths like other salmon and trout. Their native range exists in the upper Mississippi River drainage and the eastern United States in mountainous stream habitats that have permanent cool or coldwater sources. During the summer, brook trout head upstream to smaller headwaters and tributaries to seek shaded, cooler waters as the downstream waters heat up from warm summer temperatures. There, they spawn in the fall, typically from early October to mid-November. After spawning and the arrival winter, they head back downstream to deeper pools, where they can avoid anchor ice – ice that forms below the surface of a body of water, attached to the bottom or to submerged objects.
