The first one-room school building in Lake Linden and Hubbell was erected in 1867 and used by all denominations for church services and for all town meetings and entertainment. Two additions were added, with funding for the first from taxation and the second by Calumet and Hecla Mining Company. In 1883, there were seven hundred and fifty-four pupils of school age with an attendance of six hundred in thirteen departments served by thirteen teachers; the directors of the school were authorized to establish a high school, so the building was rearranged to provide suitable facilities for use as a high school as well as a grade school. After a quarter of a century of use, the school building was sadly outgrown. The number of Lake Linden and Hubbell children had been steadily increasing since the first high school classes had been offered in 1883. In addition, St. Ann's Academy was to discontinue high school instruction with the June 1915 graduation ceremonies. This would add fifty or more students a year to the public school enrollment. The new structure was completed in 1918. It served not only the Lake Linden and Hubbell area, but all surrounding towns and hamlets. The building was named the Washington High School.
