From Tucson-based water resource consulting firm Montgomery & Associates:
"The Colorado River’s low flows and Lake Mead’s photogenic bathtub rings are again making headlines — but the most vulnerable component of Arizona’s water supply system today is its power supply."
"The Navajo Generating Station, a 2250 MW coal-fired plant, provides nearly all the power required to operate the Central Arizona Project. The plant’s future depends on the willingness of its partners / owners to invest in its continued operation."
|The Mark Wilmer Pumping Plant pumps water approximately 824 feet from Lake Havasu to enter the CAP aqueduct system. In total, the CAP lifts water more than 3,000 feet and transports it 336 miles, from Lake Havasu, through Phoenix, and to Tucson.|
Bottom line for Arizona: "Regardless of whether NGS shuts down or continues to operate, the power plant responsible for moving most of Arizona's water plant is going to have a major impact on the price and availability of Colorado River water supplies in Arizona in the near future."
