The Mayhem was founded in August 2008 by two local women, Amanda Boucher and Stephanie Powers, after Boucher encountered the sport on a visit to Austin, Texas. By May 2009, the league had twenty skaters, and had played two bouts to around 200 fans. The league was accepted into the Women's Flat Track Derby Association Apprentice Program in January 2010, and it graduated to full membership in December 2012. In May 2011, one of its practice venues, the Green Island Ice Arena, was severely damaged by a tornado. WFTDA rankings
