Climate change is destabilizing the Colorado River Basin. Where do we go from here?

In June, a portion of my neighborhood in Flagstaff, Arizona, was put on pre-evacuation notice due to a nearby wildfire. A few weeks later, storms dumped heavy rains over a burn scar from a 2019 fire that caused destructive floods through parts of town. So far, this summer has been our third-wettest monsoon season on record, a complete contrast from our two driest monsoon seasons on record in 2019 and 2020.

These extremes are just a few local examples of the havoc that climate change is causing around the world. Here in the West, we are now in uncharted territory with the first-ever shortage declaration on the Colorado River.

How to advance water security for Arizona? These 3 bills are a good start.

With dozens of water bills introduced in the Arizona Legislature this session, EDF Action and the Water for Arizona Coalition are focusing on long-overdue steps needed to ensure water security for all, especially rural communities that face high water risk.

Rural Arizona is the only substantial region left across the seven Colorado River Basin states where an “open access” approach to groundwater management is still the norm. This anything-goes approach puts people and ecosystems in rural Arizona at a disproportionate risk of water insecurity and economic instability. Read More »

Rural Arizonans need these tools to manage declining groundwater resources, fast

In some parts of rural Arizona, groundwater is the primary or only source of water for households, farmers and entire communities. But groundwater pumping has caused wells, rivers and springs to go dry.

A study by Arizona’s Department of Water Resources found that areas of Mohave County, which includes Kingman, may have only 60 years of groundwater remaining under certain pumping scenarios. Last month, the U.S. Geological Survey presented a new study showing areas of Mohave County could have over 100 years of groundwater supply.

The USGS study assumed that farmers will switch to less water-intensive crops and that new acreage won’t be converted to farmland. The difference in projections between these studies demonstrates that how we collectively manage and use groundwater matters, leading Mohave County Supervisor Gary Watson to conclude, “time is of the essence.” Read More »
