There is a perception that if only farmers would do a better job of conserving water, by lining canals or switching to a more efficient irrigation such as a center pivot or drip systems, we would have plenty of water to meet the anticipated (future) gap. The reality is that while there are opportunities for agricultural water conservation, opportunities for producing significant amounts of transferable water for municipal uses are constrained by certain legal, physical and economic factors. That comes directly from a pamphlet developed by the Colorado Agricultural Water Alliance called “Can agricultural water conservation and efficiency provide the water needed for Colorado's future?” It's an easy-to-read explanation of where the state gets its water, what happens to it, and while conservation is part of the puzzle to solving future needs, it is not the entire answer by any stretch of the imagination.
