If the lake level drops below 3,490 feet - termed the minimum power pool - the turbines that generate electricity have to be shut down. When the water level reaches critically low thresholds, air is sucked down like a whirlpool into the penstocks, forming explosive bubbles which can cause massive failure inside the dam.
The largest share, $235 million, will be used to rehabilitate the Delta-Mendota Canal, which carries water to farmlands. An additional $200 million will help continue repairs on the Friant-Kern Canal, another key conduit for water in the valley. Sinking ground, an effect of heavy groundwater pumping, has damaged segments of the Friant-Kern Canal and reduced its capacity.
Formal groundbreaking for the Ahmanson Ranch project, a town-style development on 2,800 acres in the Simi Hills in southeastern Ventura County, will not take place until 2001. However, the project has already achieved historic status for the size of the private-to-public land transfer it produced and for reviving a design concept that marks a major departure from the car-dependent suburban enclave typical of the postwar era.
The patchwork efforts to identify and safely remove contamination left by the 2025 Eaton and Palisades fires has been akin to the Wild West. Experts have given conflicting guidance on best practices. Shortly after the fires, the federal government suddenly refused to adhere to California's decades-old post-fire soil-testing policy; California later considered following suit. Meanwhile, insurance companies have resisted remediation practices widely recommended by scientists for still-standing homes.
"If you just dropped in from another planet and you didn't know and you started looking at L.A. wildfires ... you would think the only area that was hit was Pacific Palisades," said Earl Ofari Hutchinson, president of the Los Angeles Urban Policy Roundtable. "West Altadena has gotten lost in the shuffle." The historically Black community, made up primarily of working-class families, didn't receive evacuation alerts until the fire had already descended on their neighborhoods.
"I have never seen this much damage, you know. There's other kinds of damage, like graffiti around or like pulling wires and things like that, but I have never seen anything like this. It's so disrespectful," Deshpande said.
The question of how to protect fish and the ecological health of rivers that feed California's largest estuary is generating heated debate in a series of hearings in Sacramento, as state officials try to gain support for a plan that has been years in the making. "I am passionate that this is the pathway to recover fish," said state Natural Resources Secretary Wade Crowfoot. "This is the paradigm we need: collaborative, adaptive management versus conflict and litigation."
A group of local activists took matters into their own hands Saturday and removed the controversial fence illegally blocking public access to Daly City's Thornton Beach. In a video shared on Instagram, a banner that reads, This is on stolen Ohlone land, is placed on the ground as the activists begin to remove the fence, declaring, Free the land. [F12Unity/Instagram]
Waterways across Contra Costa County are increasingly threatened by invasive plant species that engulf canals and drains, decreasing biodiversity and reducing safe habitats for wildlife. In an effort to address and restore the environment, the Contra Costa County Flood Control and Water Conservation District is working to reverse that trend. The district hosted its recent 12th annual Giving Natives a Chance event at the Clayton Valley Drain near Concord's Hillcrest Community Park, inviting volunteers from across the county to plant native species around waterways and drains.
So, with this storm surge and the King tide event, it was a great opportunity for us to test this out. So, we came out here and we were able to further document and see how well it performed. So, we got to see that the king tide came up very close to where the pathway is behind you, and it did what it's supposed to do,
