GRAND HAVEN, city of Michigan, U.S.A., on Lake Michi gan, at mouth of the Grand river, about opposite Milwaukee; port of entry and the county seat of Ottawa county. It is on Federal highways 16 and 31, and is served by the Grand Trunk and the Pere Marquette railways, by lake steamers, and by inter urban motorbus and trolley lines. The population was 7,205 in 1920 (82% native white) and was 8.345 in 1930 by the Federal census. The resident population is more than doubled in summer by visitors to the city and to other resorts near by, especially the village of Spring Lake, 1 m. north. Grand Haven ships large quantities of celery, and over 1,000,000 crates of fruit annually to the Chicago market. It has over 3o manufacturing plants, making almost as many different products, and a large fishing in dustry. The traffic of the port (very largely car-ferry traffic) amounted in 1927 to 1,238,902 tons, valued at $212,468,750. A trading post was established here about 1821 by the American Fur company. Permanent settlement began in 1834, and a town was laid out in 1836. The city was chartered in 1867. Since 1916 it has had a city-manager form of government.
