Camas County is a county in the southern portion of the U.S.
state of Idaho. The county seat and largest city is Fairfield. The county was
established 104 years ago in 1917 by the Idaho Legislature with a partition of
Blaine County on February 6. It is named for the camas root, or Camassia, a
lily-like plant with an edible bulb found in the region, that Native Americans
and settlers used as a food source. As of the 2010 census, the population was
1,117, making it the second-least populous county in the state (trading places
with Clark County)
