Our region has suffered from measurable drought conditions on three different occasions (2002, 2005, and
2007-2008) between 2000 - 2010. Below is graphical data detailing demand and consumption information for
the period of 2000 - 2009. Demand figures in the graphs are displayed in "millions of gallons per day"
(MGD). Included is the reduction in demand that was obtained through the issuance of varying levels of
water restrictions. Restriction "stages" were changed in June 2009 with the adoption of the new Year-Round
Water Efficiency Ordinance.
