History
Lincoln Township was formed out of part of Waterman Township after its population grew and it became necessary to divide the township.[8] House File 390, which officially established Lincoln Township, was passed by the Iowa House of Representatives in 1886.[9] The first settlers moved to Lincoln Township from Hardin County, Iowa, in 1870. In 1881, the population of the township was 36; in 1885, 53; and in 1914, around 185. A branch of the Burlington, Cedar Rapids and Northern Railway used to run through the northwest part of the township, with a station at Plessis.[8]
