agriculture soon gave way to the production of grain for the market.
The end of Indian hostilities in the 1870s opened adjacent mountain
rangelands during the summer for a range livestock industry, mostly
large sheep herds. Hay production increased subsequently. As the settlement
grew, poultry production for both meat and eggs also increased in importance.
Turkey raising and processing began just prior to World War II, and
have become major enterprises since 1947. Irrigation of all croplands
is necessary because the climate at Manti is semi-arid. During the 1980s
irrigation practices converted from the ditch-and-furrow to the more
sophisticated sprinkler types, both in town and farmlands. Sewer lines
and natural gas were also introduced in those periods.
and about 1905 most Sanpete Valley towns experienced annual summer floods,
which followed cloudbursts on overgrazed lands at elevations over 8,000
feet. In the 1890s the Manti City Council put into effect the political
action that by 1903 resulted in the protection of its watershed by the
federal Forest Service: the Manti National Forest.
