Lake Macatawa is a Lake in Ottawa Count in Michigan. The lake is about 6 miles long with a maximum width of 1.2 miles and a surface area of 1,700 acres. The average depth of the lake is variable but generally less than 10 feet (3 m), excluding a navigation channel of fixed depth that crosses the lake to allow deep draft ships to access the dock at the City of Holland. The lake occupies portions of Park township, Holland township, and the City of Holland.
The lake contains two bays of significant size: Big Bay, and the smaller Pine Creek Bay to the east. The lake is the drowned river mouth of the Macatawa (formerly known as the Black River), which feeds into the lake's eastern end in the City of Holland.
The eastern end of the lake is marked by a pickle production facility owned by the H.J. Heinze company. The remainder of the lakeshore is marked by high-income residential development. The notable exception is Holland State Parks which borders the northern shoreline of the western end of the lake.
