POWER AND IRRIGATION

PROBLEMS INSEPARABLE

In irrigation projects of any considerable size, dams and falling water are involved, and the pumping of water for irrigation is frequently necessary. Consequently, problems of power generation and distribution are inseparable from those of irrigation. Many of the feasible undeveloped irrigation possibilities remaining in the United States are of such large scope, and so greatly affect stream flows, that they must embrace river regulation, power development, flood control, navigation, and in some instances domestic and industrial water supplies, as well as irrigation.

In some instances several of the agencies benefited by river conservancy and development works must cooperate, and participate in the cost, in order that any may be benefited.

At the rate of a million yards a month, a mountain of excavated material was dumped in Rattlesnake Canyon

Jackhammers and dynamite moved a million yards of rock to make a firm, clean footing for the dam

POWER ON THE COLUMBIA BASIN PROJECT

Pumping will be done on the Columbia Basin Project as a matter of efficiency and necessity, hence some power must be developed. High-water periods fortunately occur at such times that secondary or seasonal power will take care of pumping needs, and all primary and much secondary power will be available for use on and outside of the project lands us demands for power develop.
