This report was published by the NRDC in July 2007 and is a valuable resource for water managers and anybody else trying to grasp the looming challenges that climate change is placing on our water systems. Appendix B, called "Decoupling Population Growth and Water Use" (pg. 69-73) has some especially useful graphs and figures showing how water utilities throughout the country have been able to buck the trend of perpetually increasing water use and encourage conservation among their customers.
