Flush derived its name from Michael Floersch, a pioneer settler. When the post office was opened in Flush in 1899, the postmaster-general could not pronounce
Floersch and changed the name to
Flush. Postal service was discontinued in 1927. The church and community were settled predominately with German-speaking immigrants. The church maintained German-speaking priests until 1927. The church also opened a parish school in the 1890s which ceased operation in 1976. The town was poised for increased growth with the planned expansion of a railroad through Flush in 1908. The Floersch family even constructed a grain mill in Flush that was designed to serve the railroad. However, the railroad was never constructed and the town never saw the growth the immigrants in the region expected. Most of the residents at the townsite of Flush departed for other communities by 1914. Today, all that remains of the community is the St. Joseph's Catholic Church campus, which includes a
rectory, parish hall, and cemetery flanking both sides of Flush Road. The church building was built in 1901, and was last remodeled in 2001. ==Education==
