Gull Lake is a lake in the U.S. state of Michigan, located mostly in Kalamazoo County with the northern tip extending into Barry County. The nearest major cities are Kalamazoo, 11 miles (18 km) to the southwest, and Battle Creek, 13 miles (21 km) to the southeast. The name was probably derived from the seagulls which at times come inland from Lake Michigan in large numbers. The total surface area of this lake is 2,030 acres (8 km2), with maximum depths of 110 feet (34 m). This deep, clear lake has numerous holes in excess of 75 ft (23 m), and has one large island in the south end. The shoreline of the lake is fully developed, and is ringed with homes and cottages. A notable sport fishery exists in the lake for Rainbow trout, Lake trout, Land-locked salmon, Smelt, Smallmouth bass, and Yello
