Porterville was first settled by Centerville residents Sanford and Nancy Warriner Porter in 1859. The area had abundant timber, so they built a sawmill, the first in Morgan County. A town resident began teaching school out of her home in 1862, until a schoolhouse was built in 1867.
Western Shoshone, led by Chief Washakie, continued to frequent the area to hunt and gather berries for several years after settlement began.
