The Scenic Moraine Conference was formed in 1958 by six high schools located in Washington, Fond du Lac and Ozaukee Counties:[1] Campbellsport, Germantown, Grafton, Kewaskum, North Fond du Lac and Slinger.
The Scenic Moraine Conference remained an eight-member loop for its entire existence.
The next year, Kettle Moraine[8] and Mayville[9] replaced Campbellsport and North Fond du Lac when they became charter members of the Flyway Conference.
[10] The Scenic Moraine's membership roster remained unchanged for the rest of the conference's history, but large gulfs were developing between member school districts in enrollment levels[11][12] which led to discussions on realignment between conferences in southeastern Wisconsin in the mid-1970s.
The other two schools, Kewaskum and Mayville, moved to the Eastern Wisconsin[20][21] and Flyway[22][23] conferences, respectively.
