[2] The conference's eighteen-year history was marked by instability, as they were constantly affected by defections, rural consolidation and school closings.
[5] Three years after they left the West Central Conference, Arkansaw rejoined to bring membership back up to six schools.
[6] Pepin left the West Central in 1966 to join the Dunn-St. Croix Conference,[7] and they were replaced by two private high schools: Immanuel Lutheran[8] in Eau Claire and St. Felix[9] out of Wabasha, Minnesota.
Two members left the conference in 1968, as Fairchild merged with Osseo[10][11] and St. Felix discontinued their high school program.
Two years later, Immanuel Lutheran joined the Wisconsin Independent Schools Athletic Association,[16] where they competed before its merger with the WIAA and entry into the Dairyland Conference in 2000.
