Lake Allegan is a man-made lake located in Valley Township just outside the city of Allegan in the U.S. state of Michigan (Allegan County). The water is safe for swimming and boating. The lake has a large surface area of almost 1,600 acres (2.5 mi2, 6.475 km2). Salmon runs occur on the western side of Lake Allegan's Calkins Bridge dam which leads to Lake Michigan via the Kalamazoo River.
Lake Allegan is adjacent to the 50,000-acre Allegan Forest. Geese, ducks, kingfishers, eagles and great blue herons frequent the lake. The Allegan Lake Overlook is one of the best places to view the lake located on Monroe Road, two and one half miles from M-89.
In the spring and fall, when the fish are spawning, the Calkins Bridge Dam is a favorite spot for fishermen.
