Two experts from Stanford’s Water in the West program explain the potential impacts on the future of water in California of the proposed plan to downsize the $17 billion Delta twin tunnels project. … Leon Szeptycki, executive director of Stanford’s Water in the West program, and Timothy Quinn, the Landreth Visiting Fellow at Water in the West, discussed the future of water in California and potential impacts of a tunnel system.
Major dams in California are five times more likely to flood this century than the last one due to global warming, a new study finds, possibly leading to overtopping and catastrophic failures that threaten costly repairs and evacuations. That means Californians can expect more disasters like the Oroville Dam, whose overflow channel failed in 2017 after days of flooding had filled state reservoirs to 85% of their capacity.
Over the past two years, scared off by the anticipated costs of storing water there, Valley agricultural irrigation districts have steadily reduced their ownership shares of Sites. The powerful Metropolitan Water District of Southern California … is nearly as big an investor in Sites as all of the Sacramento Valley farm districts combined. Metropolitan agreed Tuesday to contribute another $4.2 million to help plan the project.
The Colorado River has been dammed, diverted, and slowed by reservoirs, strangling the life out of a once-thriving ecosystem. But in the U.S. and Mexico, efforts are underway to revive sections of the river and restore vital riparian habitat for native plants, fish, and wildlife. Last in a series.
Gov. Stephen Roe Lewis of the Gila River Indian Community said in a statement Thursday that a decision by House Speaker Rusty Bowers to move forward with a contentious water bill threatens the community’s plan to support the drought agreement. The Gila River Indian Community’s involvement is key because it’s entitled to about a fourth of the Colorado River water that passes through the Central Arizona Project’s canal.
At long last, the Sacramento-San Joaquin River Delta twin-tunnels boondoggle is dead. Good riddance. Gov. Gavin Newsom made that official Tuesday during his State of the State address, calling instead for a smaller, single-tunnel approach that would include a broad range of projects designed to increase the state’s water supply. Bravo. It’s a refreshing shift from Gov. Jerry Brown’s stubborn insistence that California spend $19 billion on a project that wouldn’t add a drop of new water to the state supply.
Salinas Valley farmers would cover the bulk of administrative costs for a state-mandated groundwater sustainability agency charged with balancing use and recharge in the agriculture-rich region under a proposal to be considered Thursday. Farmers would pay about 90 percent of the Salinas Valley Basin groundwater sustainability agency’s proposed $1.2 million annual budget for the 2019-20 fiscal year or about $1.08 million through a $4.79 per acre annual “regulatory” fee under the proposal, while public water system customers would contribute about $120,000 per year through a $2.26 annual fee.
The interrelated nature of water issues has given rise to a management approach that integrates flood control, environmental water, and water supply. The Yuba Water Agency manages its watershed in this kind of coordinated manner. We talked to Curt Aikens, the agency’s general manager, about the lessons they’ve learned from this “integrated management” approach.
Thursday, the National Oceanic and Atmospheric Administration announced that El Niño — the periodic warming of the tropical Pacific Ocean, with weather consequences worldwide — has officially arrived. El Niño typically peaks between October and March, so it’s pretty late in the season for a new one to form. This year’s El Niño is expected to remain relatively weak, but that doesn’t mean this one won’t be felt — in fact, its cascading consequences already in motion.
Lawyers representing the state Department of Water Resources will make their case Friday for striking portions of lawsuits over the spillway crisis filed by the city of Oroville, several farms, businesses and other plaintiffs. The state is arguing that certain “inflammatory and irrelevant” allegations should be removed from the lawsuits, including allegations about racist actions, sexual harassment and petty theft by DWR employees and conspiracy to cover up or destroy documents.
Three new directors representing the cities of Fullerton and Santa Ana, and the Inland Empire Utilities Agency were seated today on the board of directors of the Metropolitan Water District of Southern California.
American Canyon will continue looking to the proposed, massive Sites reservoir in Colusa County to someday help slake its thirst. The city of about 20,000 residents is the only Napa County city without a local reservoir. It depends on the state’s North Bay Aqueduct that pumps water out of Barker Slough, a dead-end slough in the Solano County portion of Sacramento-San Joaquin Delta.
In a major shift in one of the largest proposed public works projects in state history, California Gov. Gavin Newsom on Tuesday announced he does not support former Gov. Jerry Brown’s $19 billion plan to build two massive tunnels under the Sacramento-San Joaquin River Delta to make it easier to move water from the north to the south. “Let me be direct about where I stand,” Newsom said. “I do not support the twin tunnels. But we can build on the important work that’s already been done. That’s why I do support a single tunnel.”
It’s all up to the Imperial Irrigation District. The fate of a seven-state plan to address dwindling Colorado River water supply now appears to rest squarely with the sprawling southeastern California water district. Its neighbor to the north, the Coachella Valley Water District, voted unanimously on Tuesday to approve interstate agreements that would conserve water for use by 40 million people and vast swaths of agricultural lands.
Of the handful of speakers at the California Water Service hearing Tuesday, none supported the proposed rate increases for Chico, objecting to high costs, compensation to high-level executives and profit made by shareholders.
In a recent paper, Stephanie Pincetl, director of the California Center for Sustainable Communities at UCLA, and co-authors argue that investments made over the years to fortify the city’s supply with additional imported water have not solved LA’s water shortages. … The paper asserts that LA could become water self-reliant by strategically investing in local supplies, and offers several concrete strategies for improving LA’s water security.
The new report, “Sustainable Landscapes on Commercial and Industrial Properties in the Santa Ana River Watershed,” explores how landscape conversion on commercial and industrial properties can reduce water use, increase stormwater capture and groundwater recharge, improve water quality, and reduce greenhouse gas emissions and pesticide use.
Work will soon begin on a $6 million effort to upgrade Oxnard’s wastewater treatment plant. The City Council this week awarded a contract to the Livermore-based GSE Construction Co. to upgrade facilities that are at the highest risk of failure. The project includes repairing settling tanks known as primary clarifiers, bio towers that filter waste and other equipment.
Our floodplain reforestation projects are biodiversity hotspots and climate-protection powerhouses that cost far less than old-fashioned gray infrastructure of levees, dams and reservoirs. They provide highly-effective flood safety by strategically spreading floodwater. Floodplain forests combat the effects of drought by recharging groundwater and increasing freshwater supply.
A powerful “atmospheric river” storm is expected to pummel Northern California starting Tuesday night and deliver heavy rain, gusty winds, downed trees, power outages and rough driving conditions Wednesday and Thursday. … The storm should bring up to 5 feet of new snow in the Sierra Nevada, forecasters said. The National Weather Service announced flash-flood and high-wind warnings for the Bay Area, along with Santa Cruz and Monterey counties.
