Inscription.  After heavy precipitation in the spring of 1984 averaged between 250 to 300 percent of normal, river levels were higher than normal and the ground was heavily saturated. Record (at the time) rainfall in June caused widespread flooding on the James, Vermillion, and Big Sioux Rivers from June 11 to 26, 1984.

• June 4 and 5 - heavy rain caused lowland flooding on the Vermillion and Big Sioux Rivers.
• June 7 to 11 - up to 5 inches of rain fell causing flash flooding on small tributaries and more significant flooding on the three rivers, with many roads and bridges damaged.
• June 14 to 17 - 1 to 4 inches of rain fell, then
• June 19 to 22 - up to 7 inches of rain fell over the same areas.
Roads, bridges and culverts were washed out, basements collapsed, and small dams were washed out. In South Dakota, damages were estimated at $300 million, most of which was to agriculture.

Vermillion experienced damages to its sanitary sewer infrastructure as well as severe bank erosion. Damages were estimated to be $500,000.
