Grand Mound, Iowa

History

The Chicago, Iowa and Nebraska Railroad was built through the town site in 1858, and a train station was built. Grand Mound was platted in 1866. Grand Mound was named for nearby Sand Mound; a recording error accounts for the error in spelling, which was never corrected.

Education

Grand Mound is part of the Central Community School District, based in DeWitt. Until 2001, elementary-aged students attended Grand Mound Elementary School with older students being bused to DeWitt. After the closure of Grand Mound (due to declining enrollment and concerns about the building's structural condition), students were bused to elementary schools in Welton and DeWitt; today (with Welton also closed), all elementary-aged students attend school in DeWitt.

Prior to the formation of the Central Clinton School District, Grand Mound had its own junior-senior high school, which operated in the same school building as the elementary school. Sports teams were known as the Cardinals. The last graduating senior class was in 1961, when Grand Mound—along with the Welton and DeWitt school districts—consolidated to form the Central Community School District.
