There is an acknowledged gap between future water demand and supply available in Arizona. In some parts of Arizona, the gap exists today, where water users have been living on groundwater for a while, often depleting what can be thought of as their water savings account. In other places, active water storage programs are adding to water savings accounts. The picture is complicated by variability in the major factors affecting sources and uses of water resources.

The phrase “toilet to tap” has taken on a whole new meaning in Oregon. Oregon Brew Crew (OBC), the state’s oldest home beer-brewing club, has formed an unlikely partnership with Clean Water Services, a water resources management utility that runs 4 wastewater treatment plants in the Portland area. Together they are turning recycled wastewater into beer. The duo is sponsoring the second annual Pure Water Brew Sustainable Beer Challenge, an event that breaks new ground by requiring contestants to use recycled wastewater as the base for their home-brews.

Glance up at the night sky, and you might see the movement of a celestial object belonging to a fleet of earth-observing satellites launched by the National Aeronautics and Space Administration (NASA). Eighteen earth focused satellites complete their daily orbits around the earth, not to observe and understand the far reaches of space, but to observe and understand our changing planet. Satellite observatories have the distance from Earth to observe the big picture and the technological sophistication to track changes in the biosphere at high spatial and temporal resolutions.

The Southern Arizona Water Resources Association, SAWARA, was an important force in water management for the Tucson region at a key time in its history. Marybeth Carlile, SAWARA’s founding Executive Director, was an important force in shaping SAWARA and extending its influence for the benefit of the region. Carlile passed away this spring, and presenting the story of SAWARA and its accomplishments seems a fitting way to commemorate her passing. The WRRC hosted an event in her honor on October 28, 2014, and the material for this history was assembled for that event.

Episodic streamflow events in the Upper Santa Cruz River recharge a shallow alluvial aquifer that is an essential water resource for the surrounding communities. The complex natural variability of the rainfall-driven streamflow events introduces a water resources management challenge for the region. In this study, we assessed the impact of projected climate change on regional water resources management. We analyzed climate change projections of precipitation for the Upper Santa Cruz River from eight dynamically downscaled Global Circulation Models (GCMs).

Difficulties in describing the value of water are many. This Arroyo seeks to lay out those difficulties and then examine the concept of water’s value from various perspectives. The price of water is addressed first, as that is the first and most obvious aspect of value people in the United States encounter.

The Colorado River Basin is just one example, albeit an extremely important one in the West, of a stressed river system. The Colorado River Basin Water Supply and Demand Study, released by the U.S. Bureau of Reclamation in late 2012, documents how growth, climate, economic development, and other factors point to an uncertain picture for communities, rural and urban alike. This policy brief highlights key questions communities should consider as they plan for their water futures.

In January 2014, Arizona will begin its first farmland fallowing and forbearance project. Unlike similar fallowing programs in the West, this project does not transfer the water conserved in the agricultural sector to the municipal sector. For the time being, this program seeks to conserve water in the Colorado River system. The saved water will be maintained in Lake Mead, increasing its dwindling levels and helping forestall shortages to water users in the Lower Colorado River Basin. Since 2000, water levels in Lake Mead have fallen by an alarming 100 feet.

In the City of Prescott, the Watson Woods Riparian Preserve, along Granite Creek, is an oasis for wildlife and humans surrounded by development. The city’s wastewater treatment plant and transfer station are located a block to the east, a lumber company and a concrete block manufacturer are located to the south, Highway 89 and some dense subdivisions are to the west. Over the last century, this riparian area has been a sand and gravel mine, a dumpsite, a 4-wheel playground, and a shooting range.

On Saturday, June 1, 2013, water was released from Elephant Butte Reservoir in South Central New Mexico into the Rio Grande. It took more than two days to travel the 80 miles to fields near Las Cruces, as water soaked into the parched riverbed. Waiting for the flow were chile, pecan, cotton and alfalfa growers in Southern New Mexico, Western Texas and Mexico, as well as the city of El Paso, Texas, which depends on the Rio Grande for half its water supply.

When the news reports on traces of birth control hormones or pain killers found in water, we do not know what to think. Is there any danger? How will these contaminants affect fish and other wildlife? Should we do something? What should we do? Many water contaminants are the subject of regulations that protect water quality, but many more fall into the category of substances for which we do not know the answer to these basic questions. These include substances that have been called emerging contaminants or contaminants of emerging concern (CECs).

In November 2012, five people were elected for the Central Arizona Water Conservation District. The CAWCD and its board members may not be well known to the general public, but they play an important role in Arizona water policy. The CAWCD manages, operates, and directs policy for the Central Arizona Project (CAP), the supplier of approximately 1.5 million acre-feet of water for Maricopa, Pinal, and Pima counties. This water is critical for the people of Central Arizona.
