The bottom line is that supply minus use and loss equals either a surplus or deficit in water…
Supply – Use and Loss = Surplus or Deficit
18,000 af natural + 3,500 af active mgt + 4370 af passive = 25,970 af
16,825 af pumping + 14,490 af river system losses = 31,315 af
25,970 af – 31,315 af = (-5,345 af)
Yes, there is a deficit; however, the City of Sierra Vista and other local governments and agencies are working together to mitigate water usage and keep our water a sustainable resource.
