  1. Green Valley Water Supply Water In = 28,000 af annual Water Out = 68,000 af annualOver Allocated = 40,000 af annualacre foot = usage family of 4 annually

  2. How do we know? Possibilities for Aquifer Recharge Projects in Green Valley area Monday, January 23, 2006 10 am to 12 noon Place: Water Resources Research Center University of Arizona 350 N. Campbell Avenue Tucson, Arizona 85719 Contact: Nancy Freeman Groundwater Awareness League, Inc.

  4. The Official Solution = CAP Cost for infrastructure = $30 - $100 millionGV allocations = 5,400 af allocations Deficit = 40,000 af Additional augmentation = 34,600 af

  5. Possible solutions • Check dams: • Upstream washes—El Coronado Ranch • In larger river flows • Recharge basins—Chandler • Golf course recharge basins—U of A study • Reservoirs in mountains • Individual rain water harvesting projects

  6. El Coronado Ranch It is important to start at the top of the watershed and put structures on the hillsides as well as in the streambed. We have built over 20,000 loose rock structures in the Chiricahua Mountains.

  7. Results
