Treasure Valley was formed in February 2006, shortly after the television series Rollergirls began airing, and played its first season the following year. In January 2008, it faced the top teams in the Northwest in a tournament hosted by the Rat City Rollergirls. Around this point, it had four teams: the B-Town Battalion, Cell Block B, the Devil's Darlings and the Derailers, but these were subsequently disbanded shortly after the omnibus league moved from its grass roots beginnings at Expo Idaho in Garden City to Century Link Arena in downtown Boise.
The league was accepted into the Women's Flat Track Derby Association Apprentice Program in April 2010, and became a full member of the WFTDA in September 2011. It now hosts a tournament in its own right, the annual SpudTown Knockdown, an international annual two-day double bracket elimination tournament (typically held at what is now Century Link Arena in downtown Boise over the Labor Day weekend). Aptly characterized as "the Best of the Rest of the West," inasmuch as it takes place prior to the WFTDA's Big 5 tournament, the fourth annual SpudTown Knockdown, in a return to the TVR's roots, shall be held at Expo Idaho on July 20–21, 2013.
