AbstractArizona has another Wild and Scenic River; Fossil Creek with it’s the travertine geological formations and crystal clear waters now shares the same protected designation as a segment of the middle Verde River, the state’s only other Wild and Scenic River. Approving Fossil Creek’s special designation was a detail in a massive piece of legislation, the Omnibus Public Land Management Act, a package of over 160 bills, that set aside more than 2 million acres of newly protected wilderness in nine states. More than 3.3 million acres of public lands in Arizona gained permanent protection. President Obama signed the law on March 30. Fossil Creek is an Arizona success story, an environmental rags-to-riches tale. Dammed early last century for power generation, Fossil Creek’s once quick-running water was a mere a trickle until the turn of this century. In 1999, Arizona Public Service shut down the power plants, and restoration efforts commenced. The dam was lowered and diversions ceased in June 2005, restoring full flows to the creek. This is the first Arizona watercourse to have a major water retention structure retired. In its heyday Fossil Creek was considered the fourth largest travertine system in the world. Fed by underground streams, it ran year-round almost 17 miles to the Verde River, its waters rich with calcium carbonate from the limestone aquifer below. Fossil Creek was one of 86 newly established Wild and Scenic Rivers with others located in California, Idaho, Massachusetts, Oregon, Utah, Vermont and Wyoming. Efforts are underway to gain support for a Wild and Scenic listing of another Arizona River, the Blue River, a tributary to the San Francisco River. Rivers or segment of rivers are designated Wild and Scenic to protect special qualities including scenic, recreational, geologic, and fish and wildlife; they are not to be dammed or otherwise impeded to protect their free-flowing condition. The recently passed law also provides other water-related provisions benefitting the state. Funding was authorized to support the federal government’s role in a comprehensive effort to preserve wildlife habitat along the lower Colorado River. The bill also authorized the Secretary of the Interior to consider ways to supplement water supplies in the Sierra Vista Subwatershed to benefit Fort Huachuca and the San Pedro Riparian National Conservation Area.

A recursive programming analysis of water conservation in Arizona agriculture : a study of the Phoenix active management areaLierman, Wally Kent.; Wade, James C.; Ayer, Harry W.; Cory, Dennis (The University of Arizona., 1983)Arizona agriculture faces many changes in the near future. One of the most imminent changes will come from the enactment of the 1980 Arizona Groundwater Management Act. The 1980 AGWMA is designed ultimately to curtail the use of groundwater in Arizona. Agriculture will be affected since this sector used approximately 87 percent of all water in the State in 1980. This study reports on the possible effects that a proposed pump tax and water duty policy would have on agriculture within the Phoenix Active Management Area. The PAMA is one of four such areas in the State that have been identified as needing groundwater use management. The results of this study indicate that the proposed water duty is more effective in curbing groundwater use than the proposed pump tax. Investment in more water application efficient irrigation technologies is also important in this study. However, substantial amounts of capital investment funds will be needed to begin this investment.
Water Resource Alternatives for Power Generation in ArizonaSmith, Stephen E.; DeCook, K. James; Fazzolare, Rocco A.; Nuclear Engineering, University of Arizona, Tucson; Water Resources Research Center, University of Arizona, Tucson (Arizona-Nevada Academy of Science, 1974-04-20)An examination of potential water sources for power plant cooling in Arizona is presented along with information pertinent to Arizona's future water needs relative to electrical usage growth. It has been projected that Arizona's peak electrical power demands in 1980 and 1990 will exceed that of 1970 by some 5000 megawatts and 16000 megawatts of electricity respectively. At present, the bulk of the electrical energy generated in the western states originates at hydroelectric installations. Utilization of nuclear reactors for power generation requires a larger amount of cooling water than is required for a comparable fossil-fueled plant. It is suggested that the utilization of reclaimed wastewater for cooling purposes is a viable and attractive alternative to groundwater pumpage from both economic and ecological standpoints. Savings arise from conservation of fuel normally required for well pumps, costs of well construction are not required, quantities of fresh water should be released for consumption by alternate users, and a previously unused resource would be effectively recycled.
A Rational Water Policy for Desert CitiesMatlock, W. G.; Agricultural Engineering, Soils, Water and Engineering Department, University of Arizona (Arizona-Nevada Academy of Science, 1974-04-20)Four sources of water supply for desert cities are rainfall, runoff, groundwater, and imported water, and the potential use for each varies. The government can institute various policy changes to eliminate or reduce the imbalance between water supply and demand. Restrictions should be placed on water-use luxuries such as swimming pools, subdivision lakes, fountains, etc. Water pricing should be progressive; each unit of increased use above a reasonable minimum should be charged for at an increasing rate. Runoff from individual properties, homes, storage, and supermarkets should be minimized through the use of onsite recharge wells, and various collection methods should be initiated. A campaign to acquaint the general public with a new water policy must be inaugurated.
