North Vs. South And Farm Vs. City Conflicts Continue To Roil California’s Water Politics

/in , /by /Times of San Diegoby Dan Walters

As 2018 was winding down, one of California’s leading newspapers suggested, via a front-page, banner-headlined article, that the drought that had plagued the state for much of this decade may be returning. Just weeks later, that same newspaper was reporting that record-level midwinter storms were choking mountain passes with snow, rapidly filling reservoirs and causing serious local flooding. Neither was incorrect at the time, but their juxtaposition underscores the unpredictable nature of California’s water supply. The fickleness of nature has been compounded by a decades-long, multi-front struggle among hundreds of water agencies and other interested parties over allocations of the precious liquid, not unlike the perpetual religious and ethnic wars that consumed medieval Europe.

Risk Level Raised On Integrity Of Dam In Southern California

/in , , /by /San Francisco Chronicleby Louis Sahagun

Federal engineers are raising alarms that a “significant flood event” could compromise the spillway of Southern California’s aging Prado Dam and potentially inundate dozens of Orange County communities from Disneyland to Newport Beach. After conducting an assessment of the 78-year-old structure this month, the U.S. Army Corps of Engineers announced that it is raising the dam’s risk category from “moderate” to “high urgency.” “Our concern right now is about the concrete slab of the spillway and how well it will perform if water were to spill over the top of the dam,” said Lillian Doherty, the Army Corps’ division chief. “We will determine whether or not it is as reliable as it should be.”

Prado Dam Rated A ‘High Urgency’ Risk After Spillway Problems Discovered

/in , /by /The Press-Enterprise (Riverside)by David Downey

Federal officials are working urgently to strengthen the spillway at Prado Dam near Corona to prevent it from failing in a major flood, which could imperil hundreds of thousands of people living downstream in Orange County. After a May inspection determined the dam’s spillway could perform poorly in a major flood, the dam’s risk rating was changed from “moderate urgency” to “high urgency.” Dena O’Dell, a U.S. Army Corps of Engineers spokeswoman, said Thursday, May 16, that the agency is taking immediate measures to reduce the risk that the spillway will fail. And she said the agency was preparing to launch a project in 2021 to bolster the spillway and raise it 20 feet.

OPINION: Legislature Should Support More Water Projects, Not Work To Defeat Them

/in , /by /The Orange County Registerby Bill Manis

All of us remember California’s recent five-year drought when residents were encouraged to cut back their water use, let their lawns go brown, and use barrels to collect precious rainwater. Now, well-funded, politically-connected interest groups are trying to block a new source of clean drinking water for Southern California. According to a recent report by the State Water Resources Control Board, more than one million Californians don’t have access to safe, reliable drinking water.

Owens Valley Groundwater Basin Goes Low

/in , /by /Sierra Wave Mediaby Deb Murphy

California’s Department of Water Resources came out with its latest prioritization of state groundwater basins and, tentatively, the Owens Valley basin is now low. Over the short life of the Sustainable Groundwater Management Act, Owens Valley has gone from medium to high and now low priority. That prioritization would have had an impact three years ago.

Vallecitos Water District Smokes Out Wastewater System Problems

/in , /by /Water News Network

Problems in wastewater systems can’t hide behind a smokescreen at the Vallecitos Water District. The district’s Systems Collection Department routinely performs “smoke testing” of its wastewater system. This technique can easily locate flows caused by broken or incorrectly installed sewer pipes, lateral connections, or missing/broken clean-out caps. The test is performed by introducing smoke, comprised primarily of steam, through a device similar to a fog generating machine, into the wastewater systems. Staff can see if smoke comes out of the system through any leaks or breaches.

Opinion: The Cadiz Project To Drain The Desert Is A Bad Idea

/in , /by /Los Angeles Times

There’s a tiny green patch of Mojave Desert, past Barstow but before Needles, north of Joshua Tree National Park and south of the Mojave National Preserve, where groundwater pumped from an aquifer under the arid landscape irrigates several hundred acres of crops. Rainfall that seeps from the adjacent mountains is sporadic, but sufficient to replenish what is taken from the ground while still leaving enough for the natural springs that sustain the bighorn sheep, desert tortoises and other threatened species that live in the environmentally fragile region. But the private landowner, Cadiz Inc., is interested in more than growing a few lemons among the creosote and cactus.

Pumped Hydro With Better Financing Can Compete With Batteries

/in , /by /PV Magazineby William Driscoll Mentioned: San Diego County Water Authority

Lazard’s well-known Levelized Cost of Storage analysis does not cover pumped hydro storage, and a pumped hydro cost estimate from the National Renewable Energy Laboratory is not expected until late this year, as a follow-up to an interim report. Beating them to the punch is a report by UC San Diego professor David Victor and five co-authors, Pumped Energy Storage: Vital to California’s Renewable Energy Future. The report provides the following cost comparison between pumped hydro and battery storage:

San Diego Water Department Ranks Low In National Customer-Satisfaction Survey

/in , /by /The San Diego Union-Tribuneby Jeff McDonald

Customers in Fresno are much happier with their water service than residents of San Diego. So are ratepayers in Sacramento, Los Angeles, Honolulu and Denver. In fact, a new survey found only one water provider in the western United States less popular than the San Diego Water Department — the San Jose Water Co., a for-profit utility whose corporate owner is publicly traded on the New York Stock Exchange. The city of San Diego ranked 23rd out of 24 large water providers in a customer-satisfaction survey published by J.D. Power, the global marketing and information services company based in Orange County.
