Public health officials are urging boaters, swimmers and recreational water users to be on the lookout for hazardous blue-green algae blooms as warm temperatures persist.
San Joaquin County Environmental Health Department officials said in a news release Monday that staff have posted advisory signs at local marinas warning people to stay out of the water where toxic algae is present.
On a cool February morning, around 60 people gathered in the Sierra Nevada foothills to take part in a ceremony that, for many decades, was banned.
Men and women from Native American tribes in Northern California stood in a circle, alongside university students and locals from around the town of Mariposa. Several wore bright yellow shirts made of flame-resistant fabric. For the next two days, the group would be carefully lighting fires in the surrounding hills.
A bill that would have provided the necessary funds to fix the sagging Friant-Kern Canal was killed by the state legislature on Thursday.
State Sen. Melissa Hurtado introduced SB 559 to the legislature in February 2019, but the Assembly Appropriations Committee stuck it in the suspense file since August of last year, delaying its consideration to the 2020 legislative session.
The waters off San Diego are home to the two largest kelp forests on the West Coast, and both are being closely watched by local experts who are concerned about the effects of climate change on the underwater groves.
The giant kelp forests off La Jolla and Point Loma are important to the ecosystem, said Ed Parnell, a researcher at the Scripps Institution of Oceanography in La Jolla whose studies focus on coastal ecosystems in Southern California.
The San Diego County Water Authority is partnering with the Scripps Institution of Oceanography at UC San Diego to better predict atmospheric rivers and improve water management before, during, and after those seasonal storms.
This month, Scripps’ Center for Western Weather and Water Extremes (CW3E) launched the Water Affiliates Group, which brings together cutting-edge science and hands-on water industry experience to enhance reservoir operations in light of the changing climate. The Water Authority has a long-running alliance with Scripps and is among six founding water agencies statewide.
CW3E and its partners will share and support best practices in forecast-informed reservoir operations, increase research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability.
“This partnership with Scripps Institution of Oceanography underscores our commitment to strategic, science-based decision-making and long-term planning,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “By supporting advances in forecasting, we can more efficiently and effectively manage water resources both locally and statewide. This ultimately will benefit everyone in California by helping sustain our economy and quality of life.”

Water Authority General Manager Sandra L. Kerl said the collaboration aligns closely with Governor Newsom’s Water Resilience Portfolio, which prioritizes voluntary agreements, smart water storage strategies and coordination of data collection.
“This is a great example of how water agencies are stronger together by addressing major climate challenges that affect everyone across the arid West,” Kerl said. “By combining forces with some of the leading scientists in the world, we will enhance our planning capacity and be ready to adapt to whatever the future brings.”
Atmospheric river storms cause 40% to 60% of annual precipitation and most of the flood damage on the West Coast. Managing reservoirs for both flood control and drinking water supply retention is challenging because 20th-century practices and regulations are decreasingly relevant due to changing patterns for snowmelt and rainfall.

CW3E is a leader in Forecast Informed Reservoir Operations, which uses data from watershed monitoring and modern weather and water forecasting to help water managers determine the best strategies for retaining or releasing water from reservoirs. CW3E has numerous tools and technologies that affiliates can use to augment water research and improve on-the-ground decisions of water managers. The group’s research covers water supply reliability, flood management, greenhouse gas mitigation, groundwater recharge, public safety, observations, forecasting, decision support, climate outlooks, and hazard assessment.
The Water Authority is working with CW3E to assess how better near-term and long-term precipitation forecasts can improve reservoir planning and operational management in the San Diego region by maximizing local water supplies and the reliability of water resources through a mix of planning processes and real-time decisions.
Joining the Water Authority as founding partners are Sonoma Water, Orange County Water District, Yuba Water Agency, Turlock Irrigation District, and Irvine Ranch Water District.
The two dozen major fires burning across Northern California were sparked by more than 12,000 lightning strikes, a freak weather occurrence that turned what had been a relatively mild fire season into a devastating catastrophe
With the North Bay’s LNU Complex Fire topping 124,000 acres Wednesday and new state evacuation orders emerging every few hours, local and state officials urged Bay Area residents to take a variety of precautions. The city of Healdsburg said Wednesday evening that all of its roughly 12,000 residents should be prepared to evacuate their homes “soon.”
When Gov. Gavin Newsom downsized the Delta tunnels water project last year, the idea was to save money and try to appease at least some of the project’s critics. Yet the project remains controversial — and still figures to be costly. After months of relative quiet, Newsom’s administration released a preliminary cost estimate for the scaled-back project Friday: $15.9 billion for a single tunnel running beneath the estuary just south of Sacramento.
Everybody had known for days that a heat wave was about to wallop California. Yet a dashboard maintained by the organization that manages the state’s electric grid showed that scores of power plants were down or producing below peak strength, a stunning failure of planning, poor record keeping and sheer bad luck.
A new Water Resources Development Act, or WRDA, has made headway in Congress, most recently with House passage of a bill authorizing about $9 billion for Army Corps of Engineers flood and storm protection, environmental restoration and other projects.
