It’s January 2027, and for the last few months, a super El Nino has already delivered torrential rains to the Pacific Coast of North America. California’s reservoirs have been releasing record quantities of water to preserve space for the next round of precipitation but their remaining capacity to absorb runoff is dangerously low. From the peaks of...

When choosing what policies and projects might best ensure abundant water for California’s ecosystems, farms, and cities, the role of the delta is central. Even if large scale desalination were to someday deliver over a million acre feet of water per year to California’s coastal cities, how we manage the delta affects many times that...

Whether it’s an energy project or a water project, it’s important to avoid conflating capacity with actual production, or yield. With energy projects, that difference is much more certain than with water projects. For example, in 2024, California’s lone remaining nuclear power plant at Diablo Canyon, with an output capacity of 2.4 gigawatts, would have produced...

For most of the previous century, Californians successfully designed and built big water infrastructure. In sixty years, from 1910 through 1970, we built the most impressive system of interbasin transfers in the world. The Los Angeles Aqueduct, Hetch Hetchy Aqueduct, Colorado River Aqueduct, Delta Mendota Canal, Friant-Kern Canal, and California Aqueduct. Altogether these conveyances are...

In debates over water policy in California, a common argument is that if only we managed the systems we’ve already got, there would be plenty of water for everyone. Agricultural and urban use would not have to be rationed, taxpayers and ratepayers would not have to be unnecessarily burdened, and we wouldn’t have to wait...

For the last 25 years, the US Drought Monitor (USDM), a collaborative effort by the University of Nebraska, NOAA, the USDA, and other experts throughout the country, has released a weekly map that shows the location and intensity of drought across the United States. On January 8, for the first time ever, USDM’s weekly map showed the...

A new year has begun, and here in California, 2026 promises to deliver challenges that may at last transform the state’s energy and water policies. Let’s begin with a quick look at California’s current water policies in action. The last month of 2025 delivered a series of storms that merited the distinction of being dubbed “atmospheric...

There are obvious benefits to logging, grazing, prescribed burns, and mechanical thinning of California’s forests. When you suppress wildfires for what is now over a century, then overregulate and suppress any other means to thin the forest, you get overcrowded and unhealthy forests. California’s trees now have 5 to 10 times more than a historically normal...

Despite its status as an agricultural superpower, eclipsing every other U.S. state in farm output, California’s farming sector wields relatively little influence in Sacramento. When you evaluate the state’s GDP components, the sectors that dominate are financial, IT, and services, at around a half-trillion each, followed by manufacturing and government at around $400 billion and $300...

There is a good chance that a Californian is going to be nominated to become the new Commissioner of the Bureau of Reclamation. One source of opposition to his confirmation could be senators representing states that share with California the waters of the Colorado River, concerned that a Californian will not sufficiently take into account...
