The Missouri River Activities Conference (also called MRAC) is a high school athletic and activities conference whose members are located in either the Sioux City Metropolitan Area or the Omaha-Council Bluffs Metropolitan Area, both located along the Missouri River on the border of western Iowa, United States.
Since Iowa is the only state in the nation that maintains separate governing bodies for boys' and girls' athletics, the classifications are different for each gender.
The Iowa High School Athletic Association is divided into classes (from largest to smallest) 4A, 3A, 2A, and 1A (A, and 8-player are also included for football only) while the Iowa Girls High School Athletic Union is divided into classes (from largest to smallest) 5A, 4A, 3A, 2A, and 1A.
In 2010, Sergeant Bluff-Luton, a founding member of the War Eagle Conference in 1979, began competing as the league's seventh school.
[3] Lewis Central and Glenwood were also invited, but declined, opting to continue competing in the Hawkeye Ten Conference.
