Eight members (Berlin, Laconia, Lourdes Academy in Oshkosh, Markesan, Omro, Ripon, Wautoma and Winneconne) were formerly in the East Central Conference and nine schools came from the Flyway Conference (Central Wisconsin Christian in Waupun, Horicon, Lomira, Mayville, North Fond du Lac, Oakfield, St. Lawrence Seminary in Mount Calvary, and St. Mary’s Springs and Winnebago Lutheran, both out of Fond du Lac).
[1] The conference was separated into two divisions with the ECC schools forming the Lakes Division and the Flyway members comprising the Rivers Division:[2] The first membership changes occurred in 2004, when Central Wisconsin Christian and St. Lawrence Seminary left the East Central Flyway.
Central Wisconsin Christian joined the Trailways Conference while St. Lawrence became an independent.
[3] Waupun, formerly of the Wisconsin Little Ten Conference, joined the Lakes Division with Laconia moving over to the Rivers Division:[4] The most significant change came two years later when ten schools left the conference.
Six schools from the Rivers Division (Horicon, Laconia, Lomira, Mayville, North Fond du Lac and St. Mary’s Springs) joined with Kettle Moraine Lutheran in Jackson in forming the Wisconsin Flyway Conference, three schools (Lourdes Academy, Markesan and Oakfield) became members of the Trailways Conference, and Wautoma joined the South Central Conference.
