The Prairie Conference was an IHSAA-sanctioned conference located in Northwest Indiana.
 The conference began in 1955 and lasted until 1968, when four of its member schools consolidated into Benton Central, which had formed just two years earlier from two other conference schools.
 The conference was primarily based in Benton County, with nearby schools in Jasper, Newton, Tippecanoe, and later White counties also participating.
The White River Conference was an IHSAA-sanctioned conference located within rural areas of East Central Indiana, that existed twice, once from 1954 to 1977, and from 1989 to 2010.

The Eastern Wabash Valley Conference was a short-lived IHSAA-sanctioned conference located in Northeast Indiana.
 The league started in 1959, as five schools broke away from the Eastern Indiana Conference and joined with Wells County Conference member Ossian.
 This lineup lasted only three years, as Berne would return to the EIC in 1962.
 The remaining five schools stuck together until 1966, as Geneva high school closed.
 Lancaster Central, Monmouth, and Ossian were all slated to close that next year, so the remaining four schools went their separate ways.
