Delta Tunnels Project Reaches Key Milestone As Opponents May Sue

The state has reached a key milestone in its $15.7 billion proposal to build tunnel bypasses around the Sacramento-San Joaquin River Delta as an environmental group is threatening to sue to stop it.The twin tunnels, both 40 feet in diameter and 35 miles long, would be California’s most ambitious water project since the 1950s and 1960s. The project would enable Sacramento River water to be sent directly to southern and central California farms and cities, bypassing the Delta.

 

 

Speculation About Oroville Dam’s ‘Green Spot’ Grows

A new report from a UC Berkeley group researching what caused the Lake Oroville spillway to fail in February is concerned that a green spot on the nation’s tallest dam might mean it is leaking. This is not the first time the “green spot” on the southern end of Oroville Dam has been brought up. It has been asked and answered at community meetings, where state Department of Water Resources officials have said it is caused by rain or is a natural spring. Robert Bea and his team at UC Berkeley are far from convinced.

Los Angeles Restoring Water Tunnel to Capture Runoff

Los Angeles is restoring a century-old water tunnel to capture runoff from the Sierra Nevada, which had a record snowfall this winter after years of drought. The Department of Water and Power is spending $4.5 million to repair and reopen a 2-mile-long tunnel that once carried water from the Los Angeles Aqueduct to a now-defunct reservoir, the Los Angeles Daily News reported. The tunnel is part of the Maclay Highline system of channels and tunnels that supplied water to homes and farms in Sylmar and the Sunland-Tujunga area.

Gov. Brown’s $16 Billion Water Tunnels Get Expected OK

The main California agency promoting Gov. Jerry Brown’s proposed $16 billion water tunnels gave its expected approval to the project Friday. The move by the Department of Water Resources, which is helping shepherd Brown’s tunnels project over the regulatory and financial hurdles it must clear to break ground, endorsed the tunnels as a sound step environmentally. The Democratic governor wants to remake the state’s water system by tapping two 35-mile tunnels, both of them four-stories high, into Northern California’s Sacramento River, augmenting aging pumps to the south.

California Shows How States Can Lead on Climate Change

California, which has long been a pioneer in fighting climate change, renewed its commitment to reducing greenhouse gas emissions last week by extending, to 2030, its cap-and-trade program, which effectively puts a price on emissions. It’s a bold, bipartisan commitment that invites similarly ambitious policies from other states, and it sends a strong signal to the world that millions of Americans regard with utmost seriousness a threat the Trump administration refuses to acknowledge, let alone reckon with.

An Unconventional New Captain for California’s Water Agency

California Gov. Jerry Brown last week appointed Grant Davis as director of the state’s Department of Water Resources. Davis, 54, general manager of the Sonoma County Water Agency, brings an unusual resume to the job. With a degree in political science from the University of California, Berkeley, he had never worked for a water utility until joining the Sonoma County agency in 2007 as assistant general manager. Previously, he spent a decade as executive director of The Bay Institute in Novato.

California Sues To Validate Bonds To Fund Delta Tunnels Project

The California Department of Water Resources is seeking validation of $11 billion in bonds to fund Gov. Jerry Brown’s Sacramento-San Joaquin Delta tunnel project, California Water Fix, which cleared its final environmental hurdle on Friday. In the lawsuit filed Friday, the agency says it’s seeking a judgment that confirms the validity of the bonds to fund capital costs of the tunnel project. The project calls for two tunnels up to 150 feet beneath the delta and three new intakes with 3,000-cubic-feet-per-second capacity and an average annual yield of 4.9 million acre-feet.

Exceptional Drought Levels Move Toward Zero In U.S.

At one point, the U.S. Drought Monitor map showed the presence of “exceptional drought”, the worst category designated by researchers, across much of California and a large portion of the areas of northern Texas and Oklahoma. A look at the map today shows neither of those areas has a drought problem at all. “Exceptional drought” has become a rarity across the country. The current U.S. Drought Monitor map shows relatively small areas of “exceptional drought” in a part of North Dakota and a tiny sliver of northeast Montana.

The Status of the Drought and Atmoshperic Rivers

According to the latest U.S. Drought Monitor (July 11), less than 32 percent of the state faces drought conditions and only 1 percent of the state is experiencing “severe” drought. Nowhere in the state are we experiencing “exceptional” or “extreme” drought. Governor Jerry Brown ended the drought state of emergency in most of California on April 7. A year ago, more than 90 percent of the state was in some form of drought. The drought’s end comes thanks in large part to so-called atmospheric rivers (AR) — warm weather systems that flow east from Hawaii and the western Pacific.
