What stands out about Iowa Colony’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Iowa Colony was founded in 1908 by the Emigration Land Company of Des Moines, Iowa, and received its name from Iowans G. I. Huffmann and Robert Beard. The community received a post office in 1919, and rice farming was introduced there in 1920. Although not directly on a railroad line, Iowa Colony was served by the Gulf, Colorado and Santa Fe line through nearby Manvel. The population grew slowly to twenty-seven and remained at that level until the mid-1960s. The discovery of oil in 1948 brought regional employment to the area. By 1961 the Iowa Colony post office had closed, yet during the 1960s the settlement began to grow vigorously as part of the greater Houston area. By 1973 Iowa Colony had been incorporated (in 1972), and by 1989 the town listed a population of 661. The city hall, community center, and municipal court are all housed in the same building, next to the fire department.…
In 1908, according to Wikipedia’s history of the town. the census of 1980 counted 585 people here.
