CAP (Central Arizona Project) In 1980, Arizona overdraft: 2. 5 million acre feet year

CAP (Central Arizona Project) 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 Department 14, 000 afy

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

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

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
