The California Water Model: Resilience Through Failure

/in , /by /California Water Blogby Nicholas Pinter, Jay Lund, Peter Moyle

A review of 170 years of water-related successes in California suggests that most successes can be traced directly to past mistakes.  California’s highly variable climate has made it a crucible for innovations in water technology and policy.  Similar water imperatives have led to advances in water management in other parts of the world.  A close look at California’s water model suggests that “far-sighted incrementalism” is a path to progress. Given the complexity of water management systems, better scientific information and new policy tools must be developed coherently and collaboratively over time.

Report: Valley Could See 6-9 Degree Temperature Increase By 2100

/in , , /by /The Sentinelby Ravyn Cullor

Climate change projections show the Central Valley will see more hot, dry years like 2021, but also some dangerously wet years as well.

This year has already seen high temperatures, drought and high fire risk for Central Valley residents, and Jordi Vasquez, environmental scientist for the California Department of Water Resources, said climate models show the Central Valley heating up 6 to 9 degrees Fahrenheit by the end of the century.

San Jose Relies on Water from the Sierra Nevada. Climate Change is Challenging that System

/in , , /by /KQEDby Ezra David Romero

In Santa Clara County, lawns are dry, a reservoir is nearly empty, and water restrictions are mandated. After two winters with very little rain — and San Jose’s driest year in 128 years of record keeping — the county is marked by one of the worst droughts in modern history.

Santa Clara County’s experience of drought is set apart from the rest of the state by a myriad of issues — less water from the Sierra Nevada, the effect of human-caused climate change on water supplies, and a case of incredibly bad luck.

As Climate Changes, Alternative Energy Systems Get Close Look

Officials with jurisdiction over about 80% of California’s power grid say the state faces a grim outlook as summer heat, wildfires and a severe drought intensify.

“When you step back, I think many of us are really recognizing now that climate change and these extreme heat waves happening in the earlier parts of the summer now have forced all of us to do things that we really never imagined just a few years ago,” Elliot Mainzer, president and CEO of California’s Independent System Operator, said recently.

TID Experiencing Fourth-Driest Year in 90 Years

/in , , /by /Turlock Journalby Angelina Martin

With just one month left in the precipitation year and little rainfall to show for it, Turlock Irrigation District and its customers are currently experiencing the fourth-driest year on record.

According to TID hydrologist Olivia Cramer, the Tuolumne River Watershed has received just 18.23 inches of precipitation since Sept. 1, or just about half of the historical average. The TID precipitation year, which is different from the water year, runs from Sept. 1 through Aug. 31 and will come to an end next month. The water year runs from Oct. 1 through Sept. 30.

This year’s 18.23 inches of rainfall come as the region experiences a second-straight year of drought conditions and puts 2020-2021 in the record books as TID’s fourth-driest precipitation year on record. The three driest years on record in order are 1977 (10.90 inches), 1976 (17.46 inches) and 2015 (17.50 inches).

Drought Moves DNR to Recommend Water Restrictions for More Than 500 Minnesota Cities

/in , /by /KSTP.comby Jessica Miles

The sounds of sprinklers have become silenced in many communities this summer due to dry conditions.

Michael Lee, of Buffalo, tried hard to keep his lawn up.

“It’s (the drought) not stopping the weeds. We’ve got thistles and stuff that are coming up, and I try to nip those when I can, but yeah, it’s been rough,” he said.

The Minnesota Department of Natural Resources says when the state drought plan hits a certain stage, as it now has, it triggers mandatory actions, including water restrictions.

Lake Mead Drops to a Record Low Amid Drought

/in , , /by /Los Angeles Times

Lake Mead is a water lifeline for Southern California and much of the west, but now it’s facing its first water shortage in its 85-year history.

The lake along the Nevada-Arizona border is one of the largest engineered lakes in the world, and it’s drying up at an alarming rate.

L.A. Times national correspondent Jaweed Kaleem talked about what this means for millions of people and millions of acres of farmland across the west.

Local Renewable Energy Project Gets Big Boost

/in , /by

I’m so pleased to report that a large-scale renewable energy project proposed jointly by the City of San Diego and the San Diego County Water Authority received $18 million in the state budget signed this month by Gov. Gavin Newsom. That money will advance the San Vicente Energy Storage Facility through initial design, environmental reviews, and the federal licensing process – a huge boost for a project with a huge upside for the region.

This is one of the most promising pumped energy storage solutions in California, and it would be a major asset to help avoid rolling blackouts through on-demand energy production while helping to meet state climate goals. It also could mitigate costs for water ratepayers across the San Diego region by generating additional revenue to help offset the cost of water purchases, storage, and treatment. The City and the Water Authority are developing the project together, just like they did to raise the height of the city-owned San Vicente Dam 117 feet in the 2010s.

San Vicente Energy Storage Facility project

Upon completion, the San Vicente energy project would provide up to 500 megawatts of long-duration stored energy, which will assist in meeting peak electrical demand periods throughout Southern California and help meet the goals of Senate Bill 100, which requires 60% renewable energy by 2030 and 100% zero-carbon energy resources statewide by 2045. The project will provide enough energy for about 135,000 households when operating.

We owe a debt of gratitude to Gov. Gavin Newsom and Senate President pro Tempore Toni G. Atkins for ensuring funding for this critical infrastructure project, which will create more than 1,000 construction-related jobs in addition to its other benefits.

With state funding in place, the Water Authority and the City are preparing to launch federal and state environmental reviews, seek a project license from the Federal Energy Regulatory Commission, and issue a Request for Proposals for a full-service private partner to help develop the project. Those complex components are expected to take at least four years, with construction completion forecast for 2030.

Pumped energy storage projects are designed to store excess renewable energy from solar and wind during the day, and then discharge that energy when energy use increases in the evening and renewable energy is not available.

The San Vicente project would create a small upper reservoir above the existing San Vicente Reservoir in Lakeside, along with a tunnel system and an underground powerhouse to connect the two reservoirs. The powerhouse would contain four reversible pump turbines.

During off-peak periods – when power is inexpensive and renewable supplies from wind and solar facilities exceed demand – turbines would pump water to the upper reservoir where it would act as a battery of stored potential energy. During high energy use, the system would discharge water from the upper reservoir downhill through the turbines, producing energy. The exchange between the two reservoirs would not consume water.

Water Conservation Helps San Diego Regional Supply During Drought

/in , , /by /Water News Networkby Mike Uhrhammer / Helix Water District Mentioned: San Diego County Water Authority

Water conservation is a way of life in the San Diego region, whether during drought periods or wet years. While the region is in drought like much of the Southwest U.S., San Diego County is not experiencing a water shortage. That’s because the Helix Water District, and the other water utilities serving the region, have worked together for 25 years to conserve water and invest in new water resources.
