History
    
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.
