Deschutes River Basin
Present Development
Irrigation along the Deschutes River and its tributaries is highly developed. Power production is relatively insignificant ; the total installed capacity of five small private plants is little more...

Irrigation from White River and tributaries is under three small ditch companies and many minor diversions. Storage control is of minor consequence and, in most years, water shortages occur in the late season. The stream grades are steep and the...

Post project would irrigate 12,000 acres of new land and provide supplemental water for 2,500...

Rivers would be required for a substantial part of the water supply. Investigations of the project have not yet been undertaken.
Power.—About 5,500 kilowatts of firm power could be developed on the Little White Salmon River by constructing a...

Power Utilization Regional
In 1943 more than 13,000,000,000 kilowatt-hours of electrical energy were utilized within the Pacific Northwest. About 1,000,000,000 kilowatt-hours of the total were generated by and used in industrial plants. The...
