Water
The Future of the Colorado
There’s not enough water to go around, but there’s no agreement about what to do.
The Colorado River provides water to 40 million people and about 5.5 million acres of irrigated farmland. There’s only so much water to go around, so how to divide up the water has been hotly disputed for over a century. The previous agreement has come unstuck, but finding a replacement has proved devilishly difficult. I suspect that the Feds would rather avoid this political hot-potato through a state agreement. So far, however, state negotiations haven’t been successful. Maybe the impending threat of a federal mandate will light a fire under the negotiations. Otherwise, we are probably guaranteed years of litigation while the river runs dry.

Third in a series of posts outlining key challenges and opportunities facing California’s next governor
California’s next Governor will need to grapple with a complex array of local, state, and regional water issues. Climate change, shifting population dynamics, and a changing economy are stressing California’s water systems and intensifying conflict over water resources. Floods and droughts are becoming more frequent and more severe. And there are no major new sources …

By Dave Owen, Helen E. Dahlke, Andrew T. Fisher, Ellen Bruno, and Michael Kiparsky
Around the world, groundwater mismanagement is a major driver of water crises. An emerging method for addressing such mismanagement, called managed aquifer recharge, has generated excitement among scholars and water managers. In a newly published article (Owen et al. 2025), we argue that this excitement, while often justified, should also be tempered by acknowledgment …

One after another, Trump has let loose destructive blasts at the environment to promote fossil fuels, mining, and logging.
We all know that Trump has issued a slew of executive orders since taking the oath of office. We also know that many of these are aimed to promoting fossil fuels, mining, and logging at the expense of the environment, while disfavoring renewable energy. Still, it’s impressive when you put the list together to see the full onslaught.

Trump and House Republicans are trying to ‘flood the zone’ when it comes to wrongly blaming California environmental regulations for the LA fires.
Trump’s longtime strategy of ‘flooding the zone” — aka overwhelming opponents with a flurry of announcements and superficial initiatives — took a literal turn last week, when his administration ordered the release of a significant amount of water from two dams in the Central Valley to try to score political points. As the New York …

Gov. Newsom signs AB 779, which addresses inequities in California’s complicated groundwater adjudication process.
Earlier this week the San Francisco Chronicle declared that California’s legislative session would close with just a single bill addressing injustices in the state’s water rights system. Now you can add one more to the list. Gov. Newsom signed Assembly Bill 779 into law this week. It’s an important step to reforming the state’s murky—often …

…or even a guidebook?
During one phase of my misspent youth, I travelled by bicycle in search of adventure and insight. (Hang with me, this relates to environmental management, and I’ll get to that soon.) On one tour, I started in Vietnam, ending up in Pakistan a couple years later, having made some detours and added other means of …

A trial court decision invalidated the City of San Diego’s tiered water rates. This amicus brief by the Environmental Law Clinic on behalf of California Coastkeeper Alliance and Los Angeles Waterkeeper argues a reversal is needed to pursue conservation and equity.
Court challenges to the use of tiered water rates in California are threatening the state’s own water conservation and affordability goals. That’s what’s at stake in a case called Patz v. City of San Diego. Climate change is intensifying California’s hydrologic variability and exacerbating the state’s water supply challenges. Dwindling water supplies have led …

In a recent post, my colleagues and I reported on our most recent research output in a long series of projects examining the effect of regulation on water innovation. The post describes a new framework for understanding and, ultimately, improving relationships between regulators and wastewater utility managers who are seeking to implement novel technical solutions, …
