<br />o <br />~ <br />c; <br />CJ <br /> <br />c. <br /> <br />+++++++++++++ <br /> <br />THE CENTRAL ARIZONA <br />PROJECT SYSTEM <br /> <br />From Lake Havasu, along A~izona's western border, the CAP's Hayden-Rhodes, Salt-Gila <br />and Tucson aqueducts extend 336 miles across the Arizona desert to bring water to cities, <br />farms and Indian reservations in Maricopa, Pinal and Pima counties. This aqueduct system <br />was essentially complete by June 30, 1991, except for finalization of six pumping plants in the <br />Tucson area. <br /> <br />Though completion of the aqueduct system is scheduled for 1992, the CAP will not be fully <br />functional until additional supporting facilities are completed. New Waddell Dam is rising on <br />the Agua Fria River northwest of Phoenix to provide the CAP with regulatory water storage. <br />Modifications to Roosevelt Dam on the Salt River and creation of terminal storage capability in <br />the Tucson area also will be required to complete the system. <br /> <br />The CAP, authorized for construction by Congress in 1968, is Arizona's link to bringing in <br />the state's unused share of Colorado River water. Arizona has a right to 2.8 million acre-feet <br />(af) of water per year. Running at capacity, and if water were available, the CAP could import <br />a maximum of about 1.9 million af a year on a sustained basis. However, the U.S. Bureau of <br />Reclamation, which began building the aqueduct system in 1973, estimated the CAP would <br />carry an average of 1.5 million af in each of the approximately 50 years it will take to repay the <br />federal government for constructing the project. <br /> <br />The overall estimated construction cost of the CAP is $3.7 billion. As of September 30, 1990, <br />the end of the 1989-1990 federal fiscal year, about $2.7 billion had been expended on CAP <br />construction. <br /> <br />CA WCD will repay the federal government approximately 70 percent of CAP construction <br />costs. The remainder will be absorbed by the government to cover costs associated with flood <br />control, dam safety, and non-reimbursable project functions such as recreation. Repayment <br />funds will come from an ad valorem (property) tax in.the district's three-county service area <br />and from sales of water and electricity. <br /> <br />
