Show PART II PRESENT STATUS OF IRRIGATION availability of water, precipitation during the growing season, type of crop grown, water rights, ditch losses, and irrigation management practices, Surface waters account for about 99 percent of the supply for irriga- tion and consist of flow from streams, lakes, springs, and reservoirs- The snowpack in the mountains is the principal source of water but is augmented by summer precipitation. The high mountains of the region are extremely valuable for collect- ing and storing moisture for irrigation. There is considerable variation in runoff throughout the region, corresponding to the variation in normal annual precipitation from more than 50 inches in the higher elevation areas to less than 6 inches in the lower areas. Irrigation is required in most cropland areas as only 2 to 6 inches of the precipitation is effective in crop production. Records of water diverted for irrigation within the region are available only for the larger systems. In many locations records are not kept or are not available for publication. In areas where records are kept -there is a lack of consistency in reporting from year to year. 22 |
