In addition to
farming, early industries included sawmills, a flour mill, a molasses
mill, and a furniture shop. A silk industry was started with the planting
of mulberry trees, some of which still remain in the city. Horse and
buggy were the only means of transportation available until 1875, at
which time the Utah Southern Railroad completed a line to Santaquin.
About that time, rich ore was discovered in the Tintic area. Several
mines were discovered on Santaquin ridge, or Dry Mountain, with some
copper, lead, silver, and zinc being mined; the Union Chief mine was
the most prosperous.
flooding in 1949, the Summit Creek Canal and Irrigation Company was
given approval to construct a reservoir west of the city; on several
occasions it has prevented disastrous damage to the community. A diversion
dam was completed and more than 10,000 feet of concrete pipe laid in
1971, which proved to be an efficient method of conserving valuable
water resources. Irrigation methods changed to sprinkling systems or
drip systems, enabling farmers to efficiently irrigate land that was
not level, bringing more farmland into production. Natural gas service
was brought to Santaquin in 1954, and marked a major development in
the modernization of the community.
