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.
In increasingly arid regions such as the western U.S., water managers are learning that careful management and restoration of watershed ecosystems, including thinning trees and conducting prescribed burns, are important tools in coping with a hotter, drier climate.
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.
The City of Ventura and its water customers have relied on the Ventura River as a primary source of drinking water for more than a century. Today, however, the region’s water supply is changing as the Ventura River watershed faces new, complex challenges. To protect our local water resources and safeguard the watershed for the future, we must change our approach to managing it now.
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.
Metropolitan General Manager Jeffrey Kightlinger said … the agency intends to work constructively with the Newsom administration on developing a WaterFix project “that addresses the needs of cities, farms and the environment.” But Kightlinger expressed frustration that the project will be delayed even more.
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.
Although it might sound absurd to those who still recall five years of withering drought and mandatory water restrictions, researchers and engineers warn that California may be due for rain of biblical proportions — or what experts call an ARkStorm. … In heavily populated areas of the Los Angeles Basin, epic runoff from the San Gabriel Mountains could rapidly overwhelm a flood control dam on the San Gabriel river and unleash floodwaters from Pico Rivera to Long Beach, says a recent analysis by the U.S. Army Corps of Engineers.
A landslide that dumped about 6 million cubic yards of rock and debris across California Highway 1 near near Big Sur, California, in May 2017 was the result of drought followed by deluge, a team of scientists say. … The researchers determined that water replaces air in the tiny spaces between soil particles, which greatly increased the pressure on those particles, speeding up the rate of collapse.
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.
At the end of 2017, several local rice farmers teamed up with researchers for a pilot program known as “Fish in the Fields” through the Resource Renewal Institute, a nonprofit research and natural resource policy group, to see what would happen when fish were introduced to flooded rice fields. Now in its second year of experiments, researchers have concluded that it works, with methane – a climate-changing byproduct of rice agriculture much more detrimental than carbon dioxide – being reduced by about two-thirds, or 65 percent, in flooded fields that had fish in them.
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?
When 2019 started, California’s snowpack was at 67%. Now it’s at over 136% and rising. The atmospheric rivers that are dumping rain along coastal California are also dumping massive amounts of snow in the state’s Sierra Nevada.
Many no longer recall the Great Midwest Flood despite its record-breaking precipitation, flooding and $13 billion price tag. Sure, 1993 seems like a long time ago, but I believe the reason the flood has left most people’s memory is because, over the last 25 years, the nation has experienced one devastating, record-breaking flood after another. Our memories are diluted by the frequency of such events.
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.
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.
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.
