Editorial: Oroville Is A Model Of How NOT To Deal With A Flood Emergency

A case in point is how the state Department of Water Resources has handled Lake Oroville for years. It continues despite considerable public and political pressure since the spillway collapse. Two developments last week perfectly illustrate the point. One involves awarding a nine-figure bid to a company to fix the spillway without any detail about what the company is actually doing. The other involves an independent review of what went wrong, which takes on added weight because the promised review by the government is nonexistent so far.

Water Under Oroville Spillway Probably Caused February Collapse, State Consultants Say

Official reports released Monday say the catastrophic damage to Oroville Dam’s main spillway probably stemmed from swift water flows under the concrete chute, which was cracked and of uneven thickness. The observations, contained in consultants’ reports prepared for the state Department of Water Resources, echo much of an independent assessment made for UC Berkeley’s Center for Catastrophic Risk Management. An official verdict on the cause is not due until the fall, when a separate forensics team investigating the February spillway break will submit its report.

USGS Finds Vast Reserves of Salty Water Underground

A new nationwide study has unearthed the huge hidden potential of tapping into salty aquifers as a way to relieve the growing pressure on freshwater supplies across the United States. Digging into data from the country’s 60 major aquifers, the U.S. Geological Survey reports that the amount of brackish – or slightly salty – groundwater is more than 35 times the amount of fresh groundwater used in the United States each year.

OPINION: Local Control A Key Element In Water Use Efficiency

While California is breathing a sigh of relief and rightfully celebrating an epic water year, efforts in Sacramento threaten to make seismic changes in the way our water has been managed in the Coachella Valley and across the state. Last week, the governor released a report outlining steps for long-term water conservation by residential and business water users. The Coachella Valley Water District worked alongside state agencies to provide input into that framework – we wanted to ensure that the unique circumstances of our community were reflected in the proposed legislation.

Plans For Major New Reservoir In Santa Clara County Moving Forward

Hoping to boost water supplies during future droughts, Silicon Valley’s largest water provider is working on a plan to build a new $800 million dam and reservoir in the remote hills of eastern Santa Clara County, just off Pacheco Pass. The idea, still in the early stages, could result in the construction of one of the largest reservoirs in the Bay Area — a lake that would be twice the size of Crystal Springs Reservoir along Interstate 280 in San Mateo County — and the first new reservoir built in Santa Clara County since 1957, when Uvas Reservoir near Morgan Hill opened.

Hydropower Plant Next to Joshua Tree National Park Wouldn’t Hurt The Environment, Feds Say

Federal officials have concluded that infrastructure for a proposed hydropower project — which would tap billions of gallons of groundwater in the California desert, just outside Joshua Tree National Park — wouldn’t be especially harmful to the environment. The Bureau of Land Management issued a “finding of no significant impact” Thursday for power lines and water pipelines that would enable Eagle Crest Energy Company to build a massive hydroelectric power plant in the Eagle Mountain area, which is surrounded on three sides by the national park. That finding clears the way for the agency to approve the project infrastructure in a few months, after a final protest period.

BLOG: Wet Year Spurs Proponents of New California Reservoir

As one of the wettest California winters in memory nears its end, the state’s major reservoirs are all essentially full or well above their historical average levels. It’s good news for everyone and everything that depends on water, especially after several years of reduced allocations for farmers and huge losses for salmon, which were frequently unable to spawn successfully for lack of cold water. In spite of their replenished supplies, the glass is still half empty for many farmers and urban water districts.

In Wet Years, the Peninsula Could Get By Without Desal.

A question that’s long been asked about California American Water’s proposed desalination plant – and which is brought up in several letters commenting on the project’s environmental impact report – is exactly how big it should be. What’s surprising is that, in a year as wet as this one, the plant wouldn’t even be necessary. Pure Water Monterey, a recycled water project launched by the Monterey Regional Water Pollution Control Agency and the Monterey Peninsula Water Management District, will deliver 3,500 acre-feet of water annually to the Monterey Peninsula beginning in 2018.

California’s Sierra Nevada Snowpack Is Larger Than Previous 4 Years Combined, NASA Says

The snowpack in California’s Tuolumne River Basin in the Sierra Nevada is currently larger than the previous four years combined, according to new NASA data. The 2017 California snowpack is near the largest on record, NASA’s data showed. Airborne Snow Observatory (ASO) mapping showed the Tuolumne Basin’s snowpack is twice as large as last year’s and 21 times the volume of 2015, which was the lowest on record.The combined April 1 snow-water equivalent from 2013-2016 adds up to only 92 percent of this year’s April 1 measurement, NASA added.

Drought May Be Over, But Changes It Wrought Will Be Here Into Future

California’s historic five-year drought is officially over, washed away with the relentlessly drenching rains, floods and snowstorms of this winter. But just as tougher building codes and better emergency planning follow major earthquakes, the brutally dry years from 2012 to 2016 are already leaving a legacy, experts say, changing the way Californians use water for generations to come. “There’s no question that we’ll be better prepared for the next drought because of the lessons learned in this one,” said Felicia Marcus, chairwoman of the State Water Resources Control Board in Sacramento. “This was the wake-up call of the century.”
