Another Giant California Dam Has Downstream Residents Worried

Deep in the Trinity Alps, 130 miles northwest of the troubled Oroville Dam, local officials are raising alarms about another earthen dam with documented weaknesses and limited capacity for releasing the water that has poured in from storms and melting snow. Trinity Lake, the state’s third-largest reservoir, was filled to 97 percent of its storage capacity Tuesday, and a snowpack estimated at 150 percent of normal still looms over the watershed. If the reservoir were to overtop the dam, the results would be catastrophic, said Keith Groves, a Trinity County supervisor representing the district that includes Trinity Dam.

 

San Diego Water Board Looking Into Pumped Storage Hydro

The San Diego County Water Authority board of directors on Thursday authorized the Water Authority, in conjunction with the city of San Diego, to begin seeking detailed proposals for a potential energy storage facility at San Vicente Reservoir. The project could help ease pressure on power grids by producing locally generated renewable energy on demand, and also lessen upward pressure on water rates by providing a new source of revenue.

San Diego Wants 500MW Pumped Hydro For Grid, Renewables And To Help Water Company Revenues

A 500MW energy storage facility with “5-8 hours” storage duration could be built in San Diego, California, with a local water authority seeking detailed proposals for such a project to support the grid and help integrate renewable energy.

Oroville Dam: DWR Offers Apology, Answers Questions

Gridley – “I’m sorry. I’m sorry for the impact on your lives,” Bill Croyle told a crowd of more than 250 people at the Butte County Fairgrounds. Croyle, the acting director of the Department of Water Resources, answered questions and listened Thursday evening as people stepped up to a microphone and were heard during the first of the water agency’s community meetings about the Oroville Dam spillway disaster and evacuations. Six more meetings are planned through mid-May. The next one is scheduled at 5:30 p.m. Tuesday at the Oroville Municipal Auditorium on Myers Street in Oroville.

OPINION: Rudy Salas Water Legislation Clears Committee

A bill by Assemblyman Rudy Salas, D-Bakersfield, that intends to keep drinking water safe and affordable by expanding state assistance to water systems in larger, severely disadvantaged communities, cleared the Assembly Environmental Safety & Toxics Materials Committee this week. Assembly Bill 560 was approved with a 7-0 vote. “Communities in California should not have to struggle to access safe drinking water at home,” Salas said in a news release. “The financial assistance in AB 560 will help cities like Arvin provide families with safe, clean drinking water at affordable rates.”

California Approves Funding For Paso Robles Water Treatment Plant

California water officials on Thursday approved funding for Paso Robles’ proposed $18 million tertiary sewage treatment plant, the final in a series of major infrastructure projects that will bring about 3,300 acre-feet of water to the city each year. Dick McKinley, Paso Robles’ director of public works, said Thursday that the city plans to award a contract bid next month and break ground on the plant in June or July.

California Senate Passes Bill That Would Boost Stormwater Capture Projects

A bill that would make it easier for local agencies to build projects to capture storm water and boost water supplies has passed the California state Senate. The measure, authored by Democratic state Senator Bob Hertzberg of Van Nuys, would change the way the projects could be financed. Proponents of the legislation say projects that clean, capture and recycle storm water can’t get built very easily in California.

The West Has A Tricky, Expensive Water Problem – And Even Solving It Is Controversial

A controversial California irrigation drainage deal designed to resolve one of the West’s trickiest, most expensive and longest-running water problems won approval from a key House of Representatives panel Thursday. But the debate – and uproar over the proposal – is only beginning, and its long-term fate is uncertain. On a mostly party-line 23-16 vote, the House Natural Resources Committee approved the bill to settle the irrigation dispute between the mammoth Westlands Water District and the federal government.

OPINION: Huntington Beach Desal Project is a ‘No-Brainer’

I will never forget the extraordinary experience California voters gave me over my 40 years in elected life, from local office, to congresswoman and then 24 years in the U.S. Senate representing the entire state. And when people ask me to recount the issues that are forever sealed in my memory, one of them is the very difficult challenge of climate change and the strain we are already experiencing from drought and extreme weather in our beloved state.

Oroville Dam: Mystery Foam Appears Below Damaged Spillway

Foam floated downstream and made circles on the water last week in the pool below Oroville Dam. Water quality experts are trying to determine why. Foam can happen naturally, or it can be a result of something else in the water. At this point the cause of the foam is unknown. Water tests were planned Wednesday, with lab results available in about two weeks, said Bryan Smith, supervising engineer with the Central Valley Regional Water Quality Control Board.
