The river, within the vicinity of the breaks, or dams, and close to the international boundary line, for a distance of about seven miles, flows via a throat solely 2,160 ft extensive, and is considerably larger than the territory lying to the west. And incidental to the river's seize, Imperial Valley, that new agricultural region rescued by irrigation from the Colorado Desert, an area lying under the extent of the sea, and a region that is a few day destined to grow to be worth tens of millions of dollars, is no longer in hazard of being inundated by the murky waters of this treacherous "yellow dragon" and consequently wiped practically out of existence. The primary five, nevertheless, had been poorly carried out and virtually amounted to nil in the ultimate success. Work, nevertheless, did not stop with the completion of the dam, and, since February 10, a number of miles of earth embankment have been built to insure everlasting success. The Hind Dam, which, although not a success of itself, aided in the final seize, was a conglomerate creation 170 feet vast at the bottom, 30 toes throughout at the highest and 35 toes high at the deepest places within the break.
The cost of the work to the Southern Pacific Railway Company, which, headed by Engineer Epes Randolph, engineered the undertaking, reached a mean rate of $10,000 per day for one hundred days. Colonel Randolph again assembled his forces, placed E. K. Clark, engineer of the Tucson division of the Southern Pacific Railroad, in direct cost, and work was recommenced to unravel this troublesome problem. It has created an inland sea in Salton Sink, adjoining to Imperial Valley, that covers about four hundred square miles, destroyed the works of the brand new Liverpool Salt Company, precipitated three totally different removals of several miles of the Southern Pacific Railroad, and necessitated the expenditure of many thousands of dollars towards its control, apart from threatening to submerge the Imperial Valley, a number of small cities of appreciable importance and a lot of rich mineral deposits. Its basis consisted of a heavy, sturdy mat of willow and cable, held in place by sturdy piles, about 1,one hundred in number and from forty to sixty feet in size.
The United States authorities has inaugurated steps to position Imperial Valley answerable for the government Reclamation Service, however what the outcome of the transfer might be will not be but recognized. A flood within the river quickly lower this new channel so deep as to position the circulation beyond control. Another dam, called the Clarke Dam, was built and by it the Colorado River has ultimately been permanently confined to its previous channel. The difficulty with the Colorado River, will probably be recalled, began in September, 1904. The California Development Company, promoters of the Imperial land colony, wanted more water for agricultural purposes than their outdated irrigation ditch was then supplying, and to remedy the scarcity an incision was made in the banks of the river at some extent about 4 miles below the outdated tapping level, and beneath the worldwide boundary line between the United States and Mexico.
