How Better Data is Helping to Improve Water Management in California
By Spencer Cole Careful stewardship is key for managing California’s highly sought-after water resources, but a lack of reliable data hampers this goal. That’s beginning to change, however, thanks to two things: technological advances and the passage of the Sustainable Groundwater Management Act (SGMA), which celebrates its 10th anniversary this month. SGMA has made waves in the…

How to incentivize better groundwater use
by Ellen Bruno, Molly Bruce, and Katrina Jessoe For more than a century, parts of California have been using groundwater faster than the resource can be replenished. As a result, aquifers are dwindling—a mounting challenge for irrigators, communities, and ecosystems. The negative impacts of over-extraction include subsidence, shallower wells running dry, and water-quality deterioration. If overextraction remains…

The myth of normal river flow: Drought, floods, and management of California’s rivers
By Julie Zimmerman, Jennifer Carah, Kirk Klausmeyer, Bronwen Stanford, Monty Schmitt, Mia Van Docto, Mary Ann King, and Matt Clifford Is California still experiencing drought? Even after a winter of record rainfall and snowpack, followed by a tropical storm, this is still an important question. And if you read the headlines, the answer is…yes and…

The Earth is Falling! – Land Subsidence and Water Management in California
By Jay Lund, Thomas Harter, Rob Gailey, Rick Frank, and Graham Fogg Groundwater problems are mostly invisible. However, as California has come to rely more on groundwater during the drought, land subsidence from groundwater drawdown and accumulating overdraft has become a visible concern in some areas. Some of this subsidence has been dramatic. Almost 4…

The hard work of sustainable groundwater management
By Erik Porse Under California’s new groundwater law, local agencies must adopt long-term plans for sustainably managing basins subject to critical overdraft. Preparing these plans will be challenging, requiring collaboration and compromise among water users accustomed to pumping as they please. Local agencies do not know exactly what they’re in for. They’ve never been responsible…

Modernizing California’s groundwater management
“A broad consensus appears to be building among California water users and policymakers that it is high time to establish an effective, statewide framework for groundwater management.” — Groundwater Resources Association of California, Contemporary Groundwater Issues Council As California strains under a third straight year of drought, Gov. Jerry Brown and many legislators have…

Why California’s agriculture needs groundwater management
California’s agricultural prosperity increasingly depends on groundwater availability during drought. Global markets favoring high-value nuts, fruits and wine grapes are fueling a steady conversion of farmland from annual crops and pasture to orchards and vineyards. The growing profitability of these permanent crops, however, cannot be sustained unless agricultural communities commit to preserve and manage groundwater…

Funding sustainable groundwater management in California
Ellen Hanak, Emma Freeman, Caitrin Chappelle, Brian Gray, Jay Lund, Dean Misczynski, Josué Medellín-Azuara, David Mitchell, Jeff Mount, James Nachbaur, Robyn Suddeth, Buzz Thompson One of the few current bright spots on California’s waterfront is that the drought seems to be spurring momentum to improve groundwater management in the state’s rural areas. Outside of a…

Resistance is futile: Inevitable changes to water management in California
“Denial ain’t just a river in Egypt” — anonymous By Jay Lund and Ellen Hanak Water policy in California has always been about making and resisting change. The gold mining period, the growth of agriculture and cities, and today’s environmental priorities all led to fundamental changes in water and land management, law and regulation.…

Groundwater and climate change in California
By Andrew Fisher, Graham Fogg, Joshua Viers, Jay Lund, Ruth Langridge and Patricia Holden For all the talk of climate change adaptation, California has yet to comprehensively address the effects of warmer temperatures and changing weather patterns on the state’s limited groundwater resources. To start the process, several of the leading University of California faculty…

Paradox on the Plains: As water efficiency increases, so can water use
By C.-Y. Cynthia Lin Groundwater and water conservation are critical issues in California and globally. Many of the world’s most productive agricultural regions depend on groundwater and have experienced unsustainable declines in water levels. In many places, policymakers have attempted to decrease groundwater extraction through voluntary, incentive-based conservation programs for irrigated agriculture. These policies are…

California’s groundwater problems and prospects
Under the rocks and stones, there is water underground — Talking Heads By Jay R. Lund and Thomas Harter Groundwater is one of California’s most ubiquitous, widely used resources that is unseen and misunderstood. Aquifers gather and store water and contaminants from large areas over decades to eons to support many human and ecosystem functions. …
