The Champion Dam played a role in the major flood of 1965. Ice dams formed in a number of unexpected places that year, causing large pools of water to form. Once such ice dam formed behind the Champion Dam, rising as high as 24 feet above the normal water level. The ice dam hit the ice breakers that are part of the dam structure, and the ice dam let go. A wall of water flowed down the Mississippi river, overtopping the Saint Cloud dam. The surge of water eventually flooded parts of Coon Rapids, and contributed to the already serious flooding in the Twin Cities area.
The Champion Dam marks a special location on the Mississippi River where it passes though the 1000 foot in elevation level. From Lake Itasca, the river has fallen 347 feet in 415 miles. This is a fall of about one foot per mile of river. Remarkably, we are only 121 air miles from Lake Itasca, which represents a fall of 3 feet per mile of actual progress towards the Gulf of Mexico. From this point heading south, the river has 1900 miles to fall the remaining 1000 feet, a fall of one foot every two miles.
