Trump Could Force $1.3B California Dam Expansion

The Trump administration is pushing for a $1.3 billion expansion of the 602-foot Shasta Dam in Northern California even though state officials are dead set against it, according to the Los Angeles Times. Plans include a vertical expansion the equivalent of two stories, although California state law prohibits an increase to the dam’s current height. The dam is on federal land, but similar projects in the past have deferred to state law in the permitting and construction processes.

OPINION: An Alternative Approach To Managing The Sacramento-San Joaquin Delta

The State Water Board is updating the water quality plan for the Sacramento–San Joaquin Delta. This plan sets flow and water quality standards for the Delta and its watershed, affecting water supply to more than 25 million Californians and millions of acres of Central Valley farmland. Parties that would be affected by this plan – water suppliers, fish and wildlife managers, environmental nonprofits – are negotiating voluntary agreements to present to the board for consideration.

‘Atmospheric River’ Dumping Insane Amounts Of Snow At Elevations Above 8,500 Feet In The Sierra

A fierce atmospheric river blasted the northern and central Sierra overnight, dumping several feet of snow to elevations above 8,000 feet and bringing a slushy mix of rain and snow to lower elevations. On State Route 88 over the Carson Spur, Caltrans snow ploughs faced drifts that rose well above the top of their trucks. As of 11:30 a.m., the road still wasn’t clear. In the mountains, ski resorts shuttered lifts due to the high volume of snow. Squaw Valley and Alpine Ski resorts ceased operations at 3 p.m. due to high avalanche conditions.

Releases Cut To Allow Lake Oroville To Fill A Bit

The flows have been shut off through the Hyatt Powerhouse at the base of Oroville Dam, and the lake is beginning to rise. And that’s all by design, according to the state Department of Water Resources. The flows were shut down about 10 p.m. Wednesday and hadn’t resumed as of Thursday afternoon. But hours-long cutoffs have been occurring since March 8. Since March 15, water has been released for a few hours in the morning and a few hours in the evening but the penstocks in the powerhouse have been closed off for the rest of the day.

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.
