In 1980, Arizona overdraft: 2.5 million acre feet year (afy) groundwater deficit due to agriculture pumping.

• Total Colorado River allocation for Arizona? 2.8 million afy

• Total CAP (Central Arizona Project) amount? 1.5 million afy

• What is Tucson’s allocation?138,920 afy (9,500 = Metro Water District)Update: As of March 2008 = 144,021 afy

• State Trust Land Department14,000 afy

CAVSARP Facility

• How much CAP water is put in annually at the CAVSARP facility?

• What percentage is this of Tucson’s total allocation?

• What is the total that has been put into the facility?

• What is the total that has been pumped out?• What is the difference between the recharged

and the pumped out?• So this is the amount of the surplus that has

been banked.

CAVSARP: Tucson's Recharge Project for CAP water

• How much CAP water is put in annually at the CAP-SARP facility?—See data tables on next slide

• What is the total that has been put into the facility?

• As of the end of 2007 = 409,200 acre feet

• What is the total that has been pumped?

• As of the end of 2007 = 270,000 acre feet

• What is the difference between the recharged and the pumped out, which will give the amount that has been banked for future use:

• As of the end of 2007 = 139,200 acre feet
