Biography/History

The California Development Company was formed in 1896 by Charles R. Rockwood, who planned to convert the Imperial Valley desert into an agricultural oasis. Between 1900 and 1902, canals were constructed under the supervision of George Chaffey, water flowed into the Valley regulated by a wooden head gate, and thousands of new settlers arrived, and began cultivating fruits and vegetables. However, the waters of the Colorado River contained large amounts of silt, which soon interfered with delivery of irrigation to farmers, and blocked the head gate. Financially strapped, and unable to buy dredges to unclog the canals, the California Development Company began cutting a new intake from the river in summer 1904 at an unregulated point four miles south of the U.S.-Mexican border, even though they had no authority to construct a control gate there. The Colorado River flooded three times during the winter of 1905, and by March waters had broken through the dikes and were pouring into the Salton Basin at a rate of 90,000 cubic feet per second. Valuable farmland was washed away, part of the Inter-California Railroad was under water, the towns of Calexico and Mexicali were in jeopardy, and the Southern Pacific Railroad's main line from Los Angeles to Yuma was threatened. During the next two years, the Company made five attempts to control the river with no success. Finally the Southern Pacific Railroad, under the direction of E.H. Harriman, intervened in April 1906, loaning the Development Company more than $1 million, and bringing in civil engineer Epes Randolph to oversee the repair of the levees. The breach was not finally closed until January 1907.

Scope and Content

Photographs in Box 1, dated between 1900 and 1906, are divided into five sections, each with separate cover leaf bearing a typed title label: "California Development Company irrigation works before 1906, the resulting agricultural and village development, and of the agricultural and horticultural development in the adjacent Yuma Valley," shows hunting parties and mud volcanoes in the Valley before irrigation, early canal construction in 1900-1902, and subsequent cultivation of date and fig orchards, vineyards, alfalfa and corn fields, orange groves, and fields of tomatoes, cantaloupes, asparagus, and onions. There are also views of early Calexico, founded in 1900 as a tent city for workers on the Alamo Canal; farms in the Yuma Valley, and Yuma Indian families. Section 2 documents the intake canals, the "break", and efforts during 1904-1905 to close the breach; Section 3 shows construction of the Rockwood Headgate, attempts to divert water through it, and its failure, Jan.-Oct. 1906; Section 4 contains views of the effects of flooding in the Imperial Valley into the Salton Sea, Dec. 1905-March 1907; and Section 5 shows construction and operation of the concrete headgate at Hanlons, Calif. at the head of the Imperial Canal, Jan. 1906-July 1908. In addition to the photos, Box 1 contains a detailed map (36 x 28 cm) of the Colorado Delta and Imperial Valley; and a booklet of photos (14 x 22 cm) taken by James D. Schuyler, July 16, 1906, of the concrete headgate at Hanlons, and the wooden gate at the Lower Mexican Intake. Box 2 documents repair operations conducted under the auspices of Epes Randolph, agent of the Southern Pacific Railroad, beginning in July 1906, with photographs arranged in six sections. Section 1 contains photos of the construction of the Hind Dam (named after T.J. Hind, superintendent of the work at the Lower Heading), and dredging by dredges "Alpha" and "Delta," which closed the breach in Nov. 1906. But floods caused a second break in Dec. 1906, and the photos in Sections 2 and 3 document the re-construction during Dec 1906 and Jan 1907 of the Hind Dam, now known as the Clarke Dam, after C.K. Clarke, superintendent of the second closing. There are views of the work crews, Indian boatmen, Indian laborers, constructing levees, quarrying rock for riprapping (filling in water with loose rock as a foundation), trestle building, transporting pilings, repairing track, and crossing the water in an aerial cable car. There are also photos of the Colorado River steamboats "Searchlight" and "St. Vallier." Section 4 contains photos of reconstruction of levees before the second break, and completion of the levee system along the Colorado River Dec. 1906-July 1907. Section 5 documents rehabilitation, extension and improvement of the Imperial Valley irrigation system, March 1906-Dec. 1909; and maintenance and extension of the levee protection works July-Dec 1907. Section 6 contains views (some cyanotypes) of Colorado River control work, Jan.-May 1911, under direction of Col. John A. Ockerson.
