Bill Hasencamp is the manager of the Colorado River Resources for California’s Metropolitan Water District, which provides treated water to 19 million people. The two giant reservoirs on the Colorado River are both below 50 percent of capacity. For now, California has avoided flexing its muscle to get its fair share of the Colorado River. “We’ll never give up that right – our first priority among all Colorado River water users — and never say we’ll give up that right,” Hassencamp told me. “ That’s our fallback position, though we’ll set it aside for now and try to work out a solution.”For Colorado, Utah, Wyoming and New Mexico, this is a clear warning.
