Mackinaw trout, also known as lake trout, are a species of freshwater fish found primarily in the cold, deep waters of the Great Lakes and other large lakes in North America. They are known for their distinctive greenish-gray color with lighter spots and can grow quite large, often exceeding 30 inches in length. These fish are popular among anglers due to their challenging catch and delicious taste. Mackinaw trout thrive in cooler temperatures and are typically found at depths ranging from 30 to 100 feet, especially during warmer months when they seek cooler waters.
