The operating agreements that govern Colorado River allocations expire at the end of this year, and negotiations between the seven states that share the water are stalled. With the federal government poised to step in and impose an agreement it formulates, the states — Colorado, New Mexico, Utah, and Wyoming in the upper basin, and Arizona,...
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...
The recently released “Water Renaissance” plan, a product of “conservation groups and tribes,” gets a very big idea right. There is no reason why California’s coastal megacities should have to import water. With that one visionary presumption, this report has made a major contribution. In fact, it doesn’t go far enough. With massive, targeted investments,...
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...
The Carlsbad desalination plant is reportedly operating at half-capacity, basically because it’s less expensive to import water from the Colorado River. That is likely to change, as Arizona’s Department of Water Resources is negotiating with the San Diego County Water Authority to purchase some of the water they get from the Colorado River. The funds from Arizona will...
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...
The premise of this newsletter is that abundant and affordable energy and water are prerequisites to solving every other challenge standing in the way of lowering California’s overall cost-of-living. Not only because the cost for energy and water directly impacts the cost to build homes, or pay household utility bills, or engage in industrial production,...
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...
After several rate hikes implemented in the last few years alone, Californians are asking why their energy bills keep climbing when they use the same amount of electricity or gas. According to a 2023 report from the Transparency Foundation, residents of California pay up to 67% more for electricity and 30% more for natural gas...
