Sierra foothills Dam, Part Of SF’s Hetch Hetchy System, Pushed To Near Failure

Heavy rain in the Sierra foothills pushed a small dam within San Francisco’s Hetch Hetchy water system to the brink of failure Thursday, sending a brief scare through the rural region where roads were closed and a few dozen residents were forced to evacuate. Officials at the San Francisco Public Utilities Commission said the danger in the area, west of Yosemite National Park, had diminished by nightfall as the storm gave way. There was no interruption to water service for the agency’s 2.7 million Bay Area customers.

California Water District Rejects Cadiz Inc.’s Proposed Mojave Desert Water Project

A company’s controversial plan to sell groundwater from the Mojave Desert ran into new opposition as a Southern California water district voted against the proposal. The board of the Upper San Gabriel Valley Municipal Water District decided not to approve a nonbinding letter of intent to purchase water from the Cadiz Inc.’s proposed project. The company is looking to pump as much as 16.3 billion gallons of groundwater a year and pipe it across the desert to sell to cities in Southern California.

Little-Known California Lawsuit Complicates Drought Plan For Lake Mead

For years, Colorado River states have been negotiating a plan to avoid the worst – a shortage in Lake Mead so bad it could trigger unprecedented cutbacks. With the region experiencing drought conditions since 2000, even California, which has senior rights, came to the negotiating table. State officials said they were willing to voluntarily reduce Colorado River allocations to keep water levels in Lake Mead – the reservoir that holds water behind Hoover Dam for Arizona, California, Nevada and Mexico – from slipping below a critical threshold.

Yep, It’s Nice Rain — But It’s No ‘Miracle March,’ Experts Say

It has all the earmarks of a “Miracle March” — heavy dousings of rain, intense flurries of snow in the Sierra and roadway havoc — but the showy display of stormy weather across California this week isn’t fooling the experts. Despite encouraging signs, including a Sierra snowpack that has risen to respectability from record-breakingly meager depths this month, meteorologists say California will almost certainly emerge from the winter drier than normal.

Federal Budget Proposal Include Sites Reservoir Study Funding

Inclusion of money for raising Shasta Dam got the most attention in a recently released federal budget proposal, but the same package also includes money for Sites Reservoir. The Department of Interior is recommending spending $33.3 million under the Water Infrastructure Improvements for the Nation Act, which was signed into law in December 2016. The biggest piece of that would be $20 million for design and pre-construction work on raising Shasta Dam 18 feet. However there’s also $4.35 million to complete a decades-old federal feasibility study on Sites Reservoir.

Relicensing: Hydro Projects Face Hurdles From Agencies Says California Farm Bureau Federation – Don Pedro Hydroelectric Project

The multipurpose aspect of many reservoir projects adds an extra layer of regulation to those projects–and gives government agencies and advocacy organizations additional opportunities to seek more water and other concessions from reservoir operators. That scenario is playing out in attempts to relicense California hydroelectric projects that also provide water supplies to farms, ranches and cities. The Turlock and Modesto irrigation districts, joint owners of the Don Pedro Hydroelectric Project on the Tuolumne River, are seeking to renew the hydroelectric facility’s 50-year-old license to operate.

Can The Salton Sea Be Saved?

If you don’t live near the fading banks of the Salton Sea, it’s easy to forget it exists — that is, until the winds pick up. Depending on which way they are blowing, gusts carry tiny, toxic particulates — and sometimes the stench of decaying fish and sulfur dioxide — from the Colorado Desert to Los Angeles, Phoenix, and points beyond. The smell is a reminder of the public health crisis that will occur if more isn’t done — and quickly — to save the sea.

‘Pineapple Express’ Forecast To Deliver Three Days Of Rain To Bay Area

A warm, wet storm known as a “pineapple express” chugged into the San Francisco Bay Area Tuesday, with the first rain falling in the early morning in the South Bay. The system driven by an atmospheric river that’s pulling moisture from the subtropics is centered in Central and Southern California, but its northern edge is forecast to bring rain to the Bay Area Tuesday through Thursday. San Francisco, Livermore and Concord are expected to record 1 to 1.5 inches across the three-day period; San Rafael and Half Moon Bay 1.5 to 2 inches; and Santa Cruz 2 to 3 inches, according to the National Weather Service.

Water Wars: Democrats Block GOP Bid To Speed Shasta Dam Enlargement

Democrats in Congress have stalled an attempt to jump start an expansion of Shasta Dam, California’s largest reservoir and a major water source for the Central Valley. Their objections blocked a Republican gambit to allow the $1.3 billion project to move forward without full up-front funding and despite objections from Gov. Jerry Brown’s administration. A Democratic leadership aide in the House confirmed to the Sacramento Bee on Monday that House Democrats rejected a GOP proposal to speed preparations for the project, by eliminating a requirement on the amount of upfront funding needed for pre-construction.

Worsening Dry Spell Won’t Tip Lake Mead Into Shortage — Yet

An already dry winter for the Colorado River has gotten worse in recent weeks, but it won’t be enough to send Lake Mead to a record low — at least not right away. Despite worsening conditions in the mountains that feed the Colorado, forecasters still expect the reservoir east of Las Vegas to contain just enough water by the end of the year to avoid a first-ever federal shortage declaration. A month ago, the Colorado River Basin was on track for its seventh-driest winter in more than half a century.
