Bloomingdale Township is a civil township of Van Buren County in the U.S. state of Michigan. As of the 2020 census, the township population was 2,930. It was established in 1845.
The village of Bloomingdale is located within the township, and is the only incorporated town. The unincorporated and tiny crossroads community of Berlamont is on the line with Columbia Township. On the eastern boundary is the city of Gobles which straddles the line with Pine Grove Township. Though half of Gobles lies within Bloomingdale Township, by law cities are considered separate from townships, though villages are not.
History
The township is largely agricultural with some small resorts along with the Van Buren Youth Camp. Much of the population lives in the village of Bloomingdale and along the lakes.
Oil was discovered in the 1930s and production has ended, though there have been efforts to start pumping again.
The Kal-Haven Trail, used heavily by bicyclists in the summer and snowmobilers in the winter, goes through the township on a former railbed in a largely southeast–northwest direction, beginning with Gobles on the east, through Bloomingdale and exiting at Berlamont.
