When growth skyrocketed in Phoenix and the East Valley during the 1990s and 2000s, housing developments started replacing decades-old farms. Now, it’s the west side’s turn. In 2000, Maricopa County had 510 square miles of agricultural land and 180 square miles of residential land west of Interstate 17. By 2017, farmland had dropped to 350 square miles while agricultural residential land grew to cover 280 square miles, according to the Maricopa Association of Governments.
What may be the nation’s largest dam removal project—delayed for years by regulatory and legal disputes of a utility, stakeholders and states over licensing and environmental permits—now may have new momentum after a hard-hitting January federal appeals court ruling. Kiewit Infrastructure West, Granite Construction and Barnard Construction are shortlisted for the $400-million project to design and deconstruct four hydroelectric dams on the Klamath River in California and Oregon.
A federal environmental analysis recommends relicensing the Don Pedro hydroelectric project and accepts a Modesto and Turlock irrigation district plan for well-timed flows to boost salmon in the Tuolumne River. The flows, combined with other measures to assist spawning and outmigrating young salmon, would commit less water to the environment than a State Water Resources Control Board plan that’s unpopular in the Northern San Joaquin Valley.
Arizona Governor Doug Ducey steered away from the term “climate change” in order to garner political support for the state’s Colorado River drought plan, he indicated Friday in an interview with a Pima Community College newspaper. In that interview, he also avoided making any connection between climate change and the “drier future” (his preferred phrase) that Arizona faces. His omission bordered on a denial of the established links between the two.
As Californians, I believe we must look west to the Pacific Ocean, where seawater desalination offers a proven, climate change-resilient solution. No longer do we need verification from Israel, the Middle East and Australia, where desalination facilities have literally helped save lives and fend off debilitating droughts due of climate change. Now, we can look much closer to home — in San Diego.
The Butte County Environmental Health Department announced Friday morning that businesses that plan on re-opening in the Camp Fire affected area and will be installing temporary water systems, including water tanks and hauling water, must contact its office prior to opening.
The Coachella Valley Water District has overhauled and modernized its IT infrastructure, as part of a $16 million capital improvement plan that will improve data management, simplify payments and boost conservation.
According to a new study from the UC Santa Cruz Institute of Marine Sciences, waves are crashing onto the coastline with more force than ever before — and this increase in wave strength is directly correlated to ocean warming.
Too often, entrenched conflicts that pit water user against water user block efforts to secure a sustainable, equitable, and democratic water future in California. Striking a balance involves art and science, compassion and flexibility, and adherence to science and the law. Felicia Marcus is a public servant unknown to many Californians. But as she concludes her tenure as chair of the State Water Resources Control Board, we owe her a debt of gratitude for consistently reaching for that balance.
This failure is twofold. First, the DCP has limited provisions for actually conserving water — only $2 million for groundwater conservation programs in active management areas. … Second, the DCP fails to address conservation for Arizona’s rivers, streams and springs, even in the face of warming and drying trends.
The Metropolitan Water District last week re-upped its turf-removal program, providing greater incentives for homeowners to replace thirsty lawns with drought-tolerant plants. In Utah, the state’s Division of Water Resources is encouraging residents to use more water so it can justify spending $3 billion on a pipeline that will take more water from Lake Powell… This tale of two states brings up an interesting question: Is water conservation de rigueur or passé?
Newsom has embraced an idea that has previously failed to gain traction in Sacramento: new taxes totaling as much as $140 million a year for a clean drinking water initiative. Much of it would be spent on short- and long-term solutions for low-income communities without the means to finance operations and maintenance for their water systems. … But the money to change that — what’s being called a “water tax” in state Capitol circles — is where the politics get complicated.
Colorado will launch a far-reaching $20 million conservation planning effort this spring designed to ensure the state can reduce water use enough to stave off a crisis in the drought-choked Colorado River Basin.
A controversial oilfield wastewater disposal operation east of Bakersfield has been shut down amid a years-long regulatory crackdown and opposition by environmental activist organizations. The Jan. 3 closure … puts an end to a practice regional water quality regulators say threatened to foul Bakersfield’s water supply through a slow process of underground migration.
There may be more in the sewage-tainted water that regularly spills over the border from Tijuana than many San Diegans realize. The cross-border pollution also contains potentially dangerous industrial and agricultural chemicals, according to a draft report compiled by U.S. Customs and Border Protection that was circulated to officials throughout the region on Wednesday.
The interrelated nature of water issues has given rise to a management approach that integrates flood control, environmental water, and water supply. The Yuba Water Agency manages its watershed in this kind of coordinated manner. We talked to Curt Aikens, the agency’s general manager, about the lessons they’ve learned from this “integrated management” approach.
Redlands’ wastewater treatment facility needs $40 million in upgrades soon thanks to years of deferred maintenance, officials say. But it could be worse – building a new facility would cost $100 million. The original plant was built in the 1960s, and the last major changes were made in 2004.
Two experts from Stanford’s Water in the West program explain the potential impacts on the future of water in California of the proposed plan to downsize the $17 billion Delta twin tunnels project. … Leon Szeptycki, executive director of Stanford’s Water in the West program, and Timothy Quinn, the Landreth Visiting Fellow at Water in the West, discussed the future of water in California and potential impacts of a tunnel system.
Major dams in California are five times more likely to flood this century than the last one due to global warming, a new study finds, possibly leading to overtopping and catastrophic failures that threaten costly repairs and evacuations. That means Californians can expect more disasters like the Oroville Dam, whose overflow channel failed in 2017 after days of flooding had filled state reservoirs to 85% of their capacity.
