Local county government began immediately, with setting up of militia beats. Mormon settlers in 1839 built the first jail and also the first gristmill. Congress in January 1840 formally created the county, which by then had 856 people. 5 forts were in operation to guard against Comanche Indians, whose raids went on as late as 1863. Dams in the Colorado River provided industrial power and created fine recreation lakes.
