CALIFORNIA'S WATER SUPPLY— STATISTICS FOR 1904. 



dam sites to determine how much of this storage capacity can be utilized. Numerous 

 reservoir sites also exist in the San Joaquin Basin, many of which have been surveyed 

 and their capacity determined. The most important of these are located in the Kings 

 and Tuolumne River Basins. The water from Kings River, increased by the supply that 

 could be made available by building storage reservoirs known to exist, would irrigate 

 double the amount of land now irrigated from this stream. 



Sacramento Valley, with its 2,661,120 acres of land of unsurpassed fertility, its 

 equable climate, its large water supply, its great range of high-priced agricultural prod- 

 ucts, its proximity to markets, and its transportation facilities, presents the greatest 

 latent opportunity for irrigation development in the West. If to this be added the 

 7,386,000 acres of irrigable land in the San Joaquin, making a total of more than 10,- 

 000,000 acres for the great valley of California, it is doubted if the irrigation possibili- 

 ties from an economic standpoint are surpassed in the world. In addition to this, 

 the water supply is such that large tracts of land can be irrigated in the Salinas, Pit 

 River and Shasta Valleys. The irrigated area can be increased in the Owens River, 

 Honey Lake and Colorado River Valleys/The water of the Colorado River is particu- 

 larly well adapted to irrigation on account of the large amount of fertilizing silt which 

 it contains. 



The irrigated area in California will be largely increased by the economical use of 

 water. 



As lands are brought under irrigation the duty of water will increase, and the 

 irrigated areas will be extended as the water plane is raised. In some localities it will 

 be necessary to keep down the water plane by pumping. This ground water can be 

 used for irrigating other lands.
