Imported Water Helps the Valley Endure Another Year of Drought

Thanks in part to a wet December that brought heavy snow to the Sierras, 2020 is off to a good start with reservoir storage levels at or above historic averages throughout most of the state – good news for San Bernardino Valley residents. Even though water districts and cities throughout the San Bernardino Valley rely on local rainfall and mountain runoff for about 70 percent of their water supply, local supplies are not enough. The region relies on Sierra snowmelt from Northern California to meet the remaining 30 percent.

Water Resource Innovation, Hard-Earned Lessons and Colorado River Challenges — Western Water Year in Review

Innovative efforts to accelerate restoration of headwater forests and to improve a river for the benefit of both farmers and fish. Hard-earned lessons for water agencies from a string of devastating California wildfires. Efforts to drought-proof a chronically water-short region of California. And a broad debate surrounding how best to address persistent challenges facing the Colorado River.

 

California Governor Restarts Giant Water Tunnel Project

SACRAMENTO, Calif. (AP) — California’s governor has restarted a project to build a giant, underground tunnel that would pump billions of gallons of water from the San Joaquin Delta to the southern part of the state.

Gov. Gavin Newsom’s administration on Wednesday issued a Notice of Preparation for the project, which is the first step in the state’s lengthy environmental review process.

Last year, Newsom halted a similar project that would have built two tunnels for the same purpose. The new project will have only one tunnel, and it will carry less water. State officials don’t know how much it will cost.

State-Federal Water Deal Takes a Bite From L.A.’s Supply

With virtually no public notice, state officials quietly gave away a significant portion of Southern California’s water supply to farmers in the Central Valley as part of a deal with the Trump administration in December 2018.

One year later, it remains unclear why the California Department of Water Resources signed the agreement, which strips the agency, during exceptionally dry years, of 254,000 acre-feet of water — about what Los Angeles consumes in six months. This change will place extra strain on urban water users during drought years. The agreement could also have potentially disastrous implications for the Sacramento River’s salmon runs, since it will negatively impact river flows and water temperatures.

Water Use Drops Nearly 32% Per Capita in Manteca

Manteca’s daily per capita use of water in 2019 was down 31.8 percent compared to 2013.

That means Manteca is now exceeding the water conservation goal of 30 percent established by the state at the height of the drought. Mantecans used 195.5 gallons per capita in 2013 compared to 133.3 gallons in 2019.

California Eyeing Lower Standard for Perchlorate in Drinking Water

California plans to halve the level at which water suppliers must test for perchlorate in drinking water.

The move is the first step in lowering the state’s drinking water standard for the chemical, which is used in rocket fuel, fireworks, and airbags, said Robert Brownwood, assistant deputy director in the State Water Resources Control Board’s division of drinking water.

 

‘Decent Storm’ With 40 mph Winds To Drench Bay Area, Deposit Snow In Sierra

A storm system from the Gulf of Alaska is poised to make Wednesday night in the Bay Area wet and windy.

The system is expected to deliver winds with gusts of up to 40 miles per hour and rain across the region, starting in the North Bay around sunset before moving south. Up to 2 feet of snow could fall in parts of Northern California and the Sierra, according to the National Weather Service, while local precipitation is expected to continue through Thursday, when showers give way to a cloudy Friday.

Legislature Plans to Address Groundwater Crisis in Rural Arizona

State legislators plan to tackle widespread problems of groundwater overpumping in rural Arizona this session, proposing bills that would make it easier to limit well-drilling in farming areas where residents have asked for help from the state to safeguard their dwindling water supplies.

At least four bills have been filed or are planned to strengthen groundwater rules and oversight in rural areas where there are no limits on pumping and where water levels have fallen dramatically. More bills are expected to be introduced in the coming days.

Is Climate Change Showing Up In The Daily Weather Forecast? It’s Complicated

Early this month, scientists announced a surprising discovery: The “fingerprint” of climate change is now detectable in everyday weather. In fact, evidence of global warming can be found in the planet’s weather every day, minute, and second since 2012.

But wait —you, a person who actually paid attention in your high school atmospheric science class, say — weather and climate are not the same! Right you are, dear reader. Weather is what happens in the moment (rain passing through, or the current temperature outside). Climate is average weather over time.

Officials Seeking FEMA Funds To Repair Problem Shasta County Dam

Officials in Shasta County are preparing to apply for federal emergency management funds to repair a dam from which they can no longer release water, that officials say is in danger of flooding during a major storm event.

Twenty miles west of Redding, near the communities of Igo and Ono, the Misselbeck Dam holds back the Rainbow Lake reservoir. In 2018 the Carr fire burned up the vegetation surrounding the 12-acre reservoir.
