Long Valley HistoryValley County Info:Established February 26, 1917 with its county seat at Cascade. Named for the outstanding topographical feature of the area, Long Valley. Fur trappers were the first white men in the area but permanent settlement did not take place until the 1880s when livestock ranchers moved into Long Valley. Since the completion of the Cascade Dam in 1948, much of the southern party valley has been covered by the Cascade Reservoir. The population was 9,862 at the 2010 census. The county seat is Cascade, and the largest city is McCall. |
