Note 1: The Republican Valley Mustangs, purple and gold, was a consolidation of Red Willow and Indianola. Republican Valley consolidated with Twin Valley (Danbury, Lebanon, Wilsonville, and Bartley) in 2003 to become the Southwest Roughriders.
Note 2: In 1999, the purple and gold Geneva Wildcats consolidated with area schools as the Fillmore Central Panthers.
Note 3: This co-op was still going as the full "Boone Central/Newman Grove," but now goes by simply Boone Central.
