In summer 2018, a plan to move Janesville Craig and Janesville Parker out of the Big Eight to the Badger South Conference for football only emerged.[1] In the spring of 2020, the conference voted to accept Sun Prairie West High School as a member once the school opens in 2022.[2] In 2022, Beloit Memorial High School announced they would be joining the Southern Lakes Conference in 2023 with the exception of Football, which will move to the SLC in fall 2022.https://www.beloitdailynews.com/sports/beloit-memorials-move-to-southern-lakes-conference-approved/article_b1c4e5d8-a014-11ec-bde6-17aa1f314b9c.html
