- How changes in mountain snowpack affect available water.
- Which basins in the arid West are most at risk.
- How existing water allocation laws and regulations compare to proposed modifications in managing these changes.
- How changes in available water, and laws and regulations, affect the economic well-being of various groups in society.
Mountain snowpack is melting earlier, leaving water regulators searching for new approaches and farmers concerned about the risk to their crops. To help stakeholders find solutions, the U.S. Department of Agriculture on Thursday awarded $4.9 million to an interdisciplinary team of researchers from five institutions in three states, including Arizona State University. Mountain snowpack and rainfall are the primary sources of water for the arid western United States, and water allocation rules determine how that water gets distributed among competing uses. But earlier melting of mountain snowpack is altering the timing of runoff, putting additional pressure on reservoirs to meet the needs of agricultural water rights holders. Over the next five years, scientists from ASU will join researchers from the University of Nevada, Reno; Desert Research Institute; Colorado State University and Northern Arizona University to use a new $4.97 million grant from the USDA National Institute of Food and Agriculture to explore different aspects of this issue:
