On two recent occasions I have heard Orange County Water District Board Member Cathy Green project that "we" needed another 80 to 90 thousand acre feet of water by 2035 due to projected population increases. Many, if not most public agencies rely heavily on population growth as a driver of future water demand forecasts. It seems logical at first blush; more people, more demand. But the reality is more nuanced, and population and consumption are becoming poorly correlated due to many factors.
