<br />100° or more from late 'in June through August, but
<br />in about one summer in ten, the highest temperature
<br />reached is less than 100°.
<br />Precipitation.--Over a period of 30 years, the
<br />annual precipitation has varied a great deal from
<br />year to year. The 30-year •average a[ Rocky Ford for
<br />the period ending with 1940 was 11.31 inches; for
<br />the period ending with 1920, it was 12.72 inches.
<br />Yearly totals range from more than 22 inches to less
<br />than 6 inches. About 1 year in 10 has a total of 1b
<br />inches or~more, and about 1 year in 12 has less
<br />than 7 inches. About 1 year in 25 has 20 inches or
<br />more.
<br />6bnth ly precipitation shows wide variation from
<br />year to year. May, the wettest month of the year
<br />has had on the average less than 0.7 inch in 1 year
<br />out of S, and more than 3 inches in 1 year out of
<br />6. About 40 percent of the annual precipitation
<br />falls in the period April through June, and about
<br />75 percent in the period April through September.
<br />Ffost of this precipitation tomes from thunderstorms,
<br />which vary a greac deal in amounts of rainfall or
<br />hail. Some hail storms are severe and damaging,
<br />but these are fewer than in other high plain areas
<br />_r Colorado. Tornadoes, which occur in the area
<br />times, are general l}• smaller, less damaging, and
<br />,ess frequent than in areas farther east. Thc lo•~
<br />amount of precipitation limits agricultural activ-
<br />ity to stock raising, except in extensively irri-
<br />gated areas where intensive farming is favored by
<br />the relatively long growing season and warm summer
<br />temperatures.
<br />Farming and Ind ustry•
<br />The Homestead Ac[ of the 1870's brought an influx
<br />of settlers to Otero County. La Junta, the county
<br />seat, 'u as first settled by cattle and sheep ranchers
<br />During the same period, George Washington Swink,
<br />founder of the town of Rocky Ford, became inter-
<br />ested in farming and irrigation. He grew, improved,
<br />and marketed cantaloups and watermelons, for which
<br />the area is now well known. In the 1880 's, the
<br />Federal Government granted land to the State of
<br />Colorado. The State, in turn, sold traces to
<br />irrigation companies, in consideration that they
<br />build canals for irrigation projec cs. This offer
<br />attracted promoters and developers who built the
<br />irrigation canals that are in use at the present
<br />time.
<br />" 'Although many kinds of irrigated crops are
<br />groan in Otero Coon ty~e trend in the last few
<br />years haz been toward oducing more feed crops.
<br />The acreages. of alfalfa, torn, and so: ghum hate
<br />increased nearly every year. This increase is the
<br />result of incre azing costs of produc [ion, shortage
<br />of irrigation water, and the increased demand for
<br />feed crops. The acreage of vegetable crops remains
<br />fairly constant. Acreages of the main crops were
<br />reported in the 1964 United States Census of Agri-
<br />culture as follows:
<br />Acre s
<br />Alfalfa--------------------- 19,880
<br />Corn--------'-------------- 12,554
<br />Grain sorghum--------------- 5,150
<br />Sugar beets----------------- 3,288
<br />Barley------------------ °-- 1,137
<br />Winter wheat---------------- 2,989
<br />Oats------------------------ 1,220
<br />Anions---------------------- 1,507
<br />Pinto beans----------------- 1,29]
<br />Cantaloups------------------ 1,282
<br />Potatoes-------------------- 565
<br />Tomatoes-------------------- 925
<br />There are eight irrigation Canals and 400 to 500
<br />pumps serving the irrigated farming areas of Otero
<br />County. Plany of the pumps are used to supplement
<br />ditchwater. Even uich irrigation water, most crops
<br />grown lack adequate water for maximum production.
<br />All of the canals normally experience shortages
<br />early and late in [he growing season.
<br />Dryland farming is no longer attempted in Otero
<br />County because of the ha-.a rds of dryfarming in the
<br />prevailing climate.
<br />In recent years, the trend in the number of
<br />cattle has been upward. This [rend results mostly
<br />from an increase in livestock feeding. host ranches
<br />are cow-calf enterprises. The most popular breed is
<br />the Hereford, although the Aberdeen Angus breed
<br />is rising in popularity. The 1954 U.S. Census of
<br />Agriculture reported 59,997 cattle and calves and
<br />12,154 hogs and pigs on farms in the county.
<br />host of the industry in the county, with the ex-
<br />ception of the railroad and a brass fitting factory,
<br />is linked directly' with farming. There are two
<br />small meat packing plants, a turkey processing plant,
<br />a wool processing plan[, two 'canneries, and a food
<br />freezing plan[. All the sugar beets grown in the
<br />county are processed at the sugar refining factory
<br />in Rocky Ford. Several seed houses contract, har-
<br />vest, clean, and dtst rebate melon, zinnia, and
<br />vegetable seeds. Local machine and equipment shops
<br />have been inst nmental in developing and producing
<br />new machinery used in farming and processing agri-
<br />cultural produces. Several alfalfa dehydrating
<br />mi ]]s are in operation, and alfalfa pellets produced
<br />are shipped nationwide.
