Arizona Water Panel Sounds Alarm

Anne Castle, Former Assistant Secretary for Water and Science for the U.S. Dept. of the Interior, speaking at the 2016 University of Arizona Water Resources and Research Center’s annual conference  told attendees that our “Security Blankets” regarding water policy are wearing thin and that we must come up with new ideas if we want the west to remain viable as a community. Using past water records, Castle says,  ”Historical records can no longer guide us in our future predictions.” Using new studies that predate our written water records, Castle makes her case for changing both the predictors of water availability, but also the need to rethink the current methods of how we determine “the no injury rule” that guides most water law in California.
