WICHITA, Kan. (KWCH) – A popular summer music festival doesn’t have a home after the Sedgwick County Commission voted unanimously to deny its agreement. Dam Jam was held at Lake Afton last July. It’s still being advertised for July 19-20, 2024, and tickets have already been sold. But the “biggest lake party in Kansas,” won’t happen this year, at least not in Sedgwick County.
