There is plenty of water on Mars, but it’s frozen, locked in water-rich minerals, tucked away below the surface — or a combination of those challenges, which is why we still don’t know where it all is. That’s a problem for Rick Davis, assistant director for science and exploration in the planetary science division at NASA, because he is heading the agency’s project to evaluate potential human base sites on the Red Planet.
Southern California’s native scrublands are famously tough. … They evolved along with long, hot summers, at least six rainless months a year and intense wildfires. But not this much fire, this often. The combination of too-frequent wildfires and drought amplified by climate change poses a growing threat to wildlands that deliver drinking water to millions.
The U.S. Interior Department is facing three lawsuits filed by three environmental groups who allege its plans for the 200,000-acre Klamath Basin National Wildlife Refuge Complex along the Oregon-California border violates several federal laws. A fourth complaint from six farms and agricultural groups alleges the agency has unlawfully exceeded its authority by restricting leases of refuge land for agricultural purposes.
Mount, a senior fellow at the Water Policy Center at the Public Policy Institute of California, spoke recently about managing freshwater systems with ecosystem water budgets. “I will argue that drought, because of the way we have modified this system, is the major bottleneck ecologically,” he said. “Step 1 has to be thinking about drought: how to mitigate drought and how to deal with drought – that is plan for, respond to, and recover from drought. We don’t do that at all, even though we just had this big drought.”
California Gov. Gavin Newsom has named Jared Blumenfeld, a former Obama administration official and longtime environmental advocate as the new secretary of the California Environmental Protection Agency. Blumenfeld, 49, of San Francisco, will run the agency, known as Cal-EPA, which oversees a broad range of environmental and public health regulations statewide, on topics that include air pollution, water pollution, toxics regulation, pesticides and recycling.
The paper, published in the Journal of Environmental Management, suggests that eliminating outdoor landscaping and lawns could reduce water waste by 30 percent. It recommends importing water only when Los Angeles is not in a drought, to build a surplus of water for dry years. The paper also argues that groundwater basins that catch stormwater could be used to recycle water. However, making these improvements would require the cooperation of more than 100 agencies.
As more people build homes in fire-prone areas, and as climate change and other factors increase the frequency of fires, there is a growing risk to life and property throughout the West — and a lesser known risk to the region’s already endangered water supply. At least 65 percent of the public water supply in the Western U.S. comes from fire-prone areas.
At stake is an important rule that defines which waters are protected under the Clean Water Act. It’s also poised to be a year of reckoning on the Colorado River, which supplies water to 40 million people and 5.5 million acres of farmland. And it could also be a landmark year for water management in California, with several key issues coming to a head.
The announcement finalizes prioritization of 458 basins, identifying 56 that are required to create groundwater sustainability plans under the Sustainable Groundwater Management Act. For most basins, the results are a confirmation of prioritizations established in 2015. Fifty-nine basins remain under review with final prioritization expected in late spring.
Butte County may soon have a better idea of what lies beneath its surface. Starting in late November, a helicopter took off for several days from the Orland airport to fly a pattern over an area between Chico and Orland, and southeast into Butte Valley. Dangling beneath the helicopter was a hoop loaded with devices that created a weak magnetic field and instruments that measured how that interacted with layers beneath the soil.
At issue is the proper interpretation of the law’s central provision barring the discharge of “any pollutant to navigable waters from any point source” without a permit. The term navigable waters, broadly defined as “waters of the United States,” does not generally include groundwater.
The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:
At the confluence of the San Joaquin and Tuolumne rivers, a few miles west of Modesto, work crews removed or broke several miles of levee last spring and replanted the land with tens of thousands of native sapling trees and shrubs. It’s part of a growing emphasis on reconnecting floodplains to rivers so they can absorb floodwaters. This shift in methodology marks a U-turn from past reliance on levees to protect cities and towns.

Last month, the U.S. Bureau of Land Management released a scoping report on hydraulic fracturing for oil and gas development on approximately 400,000 acres of BLM-administered public land and 1.2 million acres of federal mineral estate lands on tribal and privately held lands in Fresno, Kern, Kings, Madera, San Luis Obispo, Santa Barbara, Tulare and Ventura counties.
At the Groundwater Resources Association’s Western Groundwater Congress, a panel of experts discussed emerging issues as agencies work to develop their plans to comply with the Sustainable Groundwater Management Act, which became law in California in 2014.
Some drinking-water wells on the northeast side of Madera are being idled or abandoned because of fluctuating water levels and significant plumes of groundwater contamination by the agricultural chemical DBCP, a powerful pesticide suspected to cause sterility and cancer.
The tenth annual performance report evaluates what the state water boards do and how the environment is responding to its actions. The report presents numerous performance measures for specific outputs and outcomes.
The USDA estimates gross cash receipts for the dairy industry to be down 9 percent from the previous year but estimates poultry receipts to be 7 percent higher. After several years of strong production, gross receipts for tree fruit and nuts are expected to be slightly lower. Likewise, vegetable gross receipts are expected to be down slightly, though consumption remains stable.
