Riverdale School District 89

[3] The Riverdale Grade and High School,[4] then a part of the North Dakota Victoria School District, and built by the U.S. Army Corps of Engineers, opened in 1948.

The federal government of the United States owned that school building though it did not provide educational services there.

[6] In 1948 there was overcrowding as a number of students who had not yet signed up to go to school began attending classes.

[8] In 1953, the North Dakota State Department of Public Instruction began to recognize the school district.

[10] The high school closed in 1992,[11] with students east of the Missouri River in McClean County transferring to the high school in Underwood, North Dakota and students west of the Missouri River in Mercer County transferring to high schools in Stanton, North Dakota and Hazen, North Dakota.

Students south of Highway 1806 in Mercer County had a choice between the Stanton and Hazen high schools.

[17] Circa 1994 a decision was made to abolish Riverdale Elementary School.

[18] There were separate school reorganizing committees for each county, and each made a different decision, which meant that the state government had to decide how the district would be divided.
