Unattended Death and Biohazard Cleanup in Calumet, IA

Calumet is a small city in O'Brien County in northwestern Iowa, covering just 0.27 square miles.

Calumet began in 1887, when the Illinois Central Railroad laid a rail line and built a depot there; the town was platted that same year, quickly followed by a post office, town hall and businesses.

The railroad's choice of the Calumet site supplanted the nearby little town of Erie, which had stood a half-mile west and a mile and a half south of the new depot.

Calumet was incorporated in 1895, and when a fire destroyed much of its downtown business district in May 1897, the town rebuilt quickly.

By 1914 Calumet had grown to roughly 300 people and boasted some two dozen retail businesses, a bank, a school serving Liberty Township, two churches, a newspaper and even its own hospital.

Calumet's early settlers were overwhelmingly German immigrants from Schleswig-Holstein, the far-northern region of Germany next to Denmark — over two-thirds of Liberty Township residents reported German heritage in the 1900 census.

That German heritage ran deep: the German Evangelical Lutheran Church, established in 1891, offered worship services in Low German (Plattdeutsch) alongside English into the mid-20th century, and a 22-member Calumet German Band played from 1908 to 1913.

The Calumet school, organized in 1900, operated until 1961, when it consolidated with Sutherland's district; today Calumet is served by the South O'Brien Community School District.

Calumet's 2020 census count was 146 people in 73 households — down from a census peak of 274 back in 1940.

Calumet sits at about 1,440 feet above sea level, among the higher elevations in northwestern Iowa, and uses ZIP code 51009.
