In 1877 the Union and Jordan Irrigation-Ditch Company was founded in Cottonwood, Utah, with James Winchester appointed as the company's first water Master (the name given to the president of the company). The company's first project was to install divide gates that allocated water through a series of ditches which diverted water to or from Little Cottonwood Creek. The Little Cottonwood Creek flowed down Little Cottonwood Canyon to the Jordan River Plain and irrigated farms in parts of Salt Lake Coumnty, including such cities as Union, Midvale, Murray, West Jordan, and Sandy. Because the Union and Jordan Irrigation Company had access to regulate water from the Little Cottonwood Creek, it allowed the company to economically flourish and hold a position of strength within local communities and business.

During the 1870s and 1880s v,arious mining and smelting corporations built smelters in Murray, Midvale, and Sandy. These operations required large volumes of water to facilitate the refining process. By 1895 the Mingo Smelter Company had contracted with the Union and Jordan Irrigation Company (U & J) to furnish one-tenth of the Little Cottonwood Creek's flow for use in Mingo's operation. This gave the U & J the money it needed to expand and readjust financially.

In 1893 a dispute arose when the U & J reallocated local water rights without consulting county officials or farmers downstream. These actions were deemed illegal by various area farmers and city officials causing, the U & J to come under public scrutiny. In response to such complaints, the company contacted a Salt Lake City lawyer and the local justice of the peace, and organized an official allocation of water rights.

In 1901 the U & J began working in conjunction with local cities to supply adequate water amounts for town culinary water systems. In 1914 the U & J finalized an agreement to sell the city of Sandy water from the Little Cottonwood, which in turn provoked the city of Sandy to grant the U & J control of the town's water rights from other water sources, giving the U & J a 25 percent increase of water control in the area. Thereafter, the U & J began purchasing canals and water rights from other canal companies, such as from the East Jordan Irrigation Company. These new acquisitions diversified the U & J's holdings and increased the complexity of the company's involvement with the surrounding communities and businesses. This business expansion burdened the company with financial problems and legal obligations, and various legal suits were brought against the Company. Over time, the company slipped into debt in attempt to maintain its holdings. Over the course of the next half century however, the U & J continued to operate and was involved in numerous irrigation projects, canal constructions, and other similar ventures.

By the 1960s the company was working to keep itself from internal collapse due to shareowner dispute. Although the U & J appeared to be in good fiscal shape, some of its shareholders doubted its future. In a stockholder meeting held in February 1968, the president of the U & J stated that the company was worth $2,000,000, but a shareowner angrily arose and questioned the honesty of such a statement. By 1969 the company was exploring ways to disband. In the early 1970s, the U & J began selling its holdings and redistributing funds to shareholders. In December 1974, U & J officials met for the last time and the company was officially dissolved.
