The Colorado River is running low on water. The lifeline that slakes the thirst of 40 million southwestern residents is projected to hit a historic low mark within two years, forcing mandatory cuts to water deliveries in Arizona, Nevada and Mexico. Facing exceptional drought conditions, cities throughout the watershed this summer have imposed mandatory water restrictions, ranchers have begun selling off cows they’re unable to feed, and the river’s reservoirs are headed toward levels not seen since they filled decades ago.

A historic achievement for the San Diego region passed almost unnoticed when the San Diego County Water Authority’s Board of Directors adopted new wholesale water rates in late June. The rate-setting process highlighted how the water authority’s independent water supplies from the Colorado River are now both less expensive and more reliable than supplies from the Metropolitan Water District of Southern California. It’s an accomplishment that the region’s water officials started working toward two decades ago, and one that will bear fruit for decades to come.
Across California, Groundwater Sustainability Agencies (GSAs) are devising plans to reduce long-term overdraft. As part of the 2014 Sustainable Groundwater Management Act, GSAs will submit plans in 2020–22, which detail strategies to bring groundwater use into balance by 2040. Planning processes must assemble stakeholders and estimate sustainable yields of groundwater, quantify existing pumping, describe future options to limit overdraft and identify funding.
