The Brief

William Mullholland is often hailed as the man who brought water to Los Angeles, but there’s an earlier group Angelenos owe flowers to: The original founders of L.A., and the Zanja Madre.

The system of zanjas — Spanish for trench or ditch — was the city’s first irrigation network that brought water from the L.A. River to people’s homes and fields.

How the ditches began

For the 44 pobladores who came from New Spain (modern Mexico) to settle in today’s downtown, every drop of water was liquid gold. Having quick access to water helped sustain life and raised crops for food.

When the pueblo of Los Angeles was founded in 1781, the town was purposely located near the L.A. River. One of the first things community members built in June of that year was a water system. They joined together to carve out the first sections of a crude dirt pipeline delivering L.A. River water, the Zanja Madre (Mother Ditch), about seven weeks after settling.

They finished it in October 1781, but once the United States seized power, more zanjas were dug out. That led to the earliest industrial use of the Zanja Madre by Eagle Flour Mills in 1855, according to archeologist Marc Beherec, and more heavy use followed.

But the zanja system was delicate. The dam intake had to be repaired after rain and the ditches had to be cleaned up often for the water to reach each customer.

The Zanjero, or “water overseer,” was responsible for maintaining the system alongside a group of deputies. The position got paid better than the mayor, signifying the price tag and commodification of water.

They ensured ditches worked properly, but there was another element that made the job a big deal — they wore police badges and had the authority to arrest anyone using the water without a permit.

The city created a zanja department, but the day-to-day was still rough. At one point, zanjeros missed a day of work because all the shovels broke. Then, floods in 1884 washed out the dirt ditches and made officials go back to the drawing board. The result, costing $125,000, was to turn some of the zanjas into closed brick conduits and improve others with concrete.

The zanjas reached their prime that decade, with an estimated 6,897 acres irrigated in city limits, including vineyards and citrus farms.

By 1902, the zanja system was made up of four separate areas connecting back to the L.A. River. At its height, L.A. had 52 miles of zanja.

Why the zanjas died off

There were public-use and safety concerns.

That’s because the zanja network was a bit haphazard. Some of it was still above ground or not upgraded with cement. For example, in 1898 an association petitioned the City Council to lay pipes down on Naomi Avenue in a bid to get a “very dangerous” open zanja closed off.

In 1901, a 7-year-old boy with epilepsy fell onto an open zanja on Date Street and died.

People would bathe in these zanjas, which at some points could be 12 feet wide. Residents would go for a summer swim, dump trash, and even wash their clothes in the water they’d drink and irrigate from.

But it was William Mulholland who may have sealed the zanjas’ fate.

As superintendent of the L.A. Water Department, he wrote in a 1903 report to the board of water commissioners that “the zanja system has made its usual poor showing for the year,” making sure to show how the upkeep expenses were outpacing income.

Then, after a rainless summer, Mulholland allocated the water to the domestic drinking supply only — stripping farmers of the much needed resource — to start shutting it down.

May 1904 was the last month the city zanja department sold water. The ditches were abandoned, but portions were repurposed for a stormwater system.

Where they’ve been found today

After more than 240 years, the zanja system has been covered up, destroyed, and forgotten.

But every so often, parts of it come to light.

Eighteen archaeological encounters with the system have been documented as of 2022, though there have likely been more times people have come across the pipes.

But officially, crews have found it during things like Metro line work, street widenings, and building construction.

You can run into the zanja system, too. Olvera Street has a brick path extending from the fountain that represents the route of the Zanja Madre, and the Stimson House on Figueroa Street still has the above ground barriers up.

Republican Sonja Shaw conceded the race for California Superintendent of Public Instruction to Democrat Richard Barrera late Wednesday evening.

“Last night voters made their choice. I would be lying if I said my heart wasn’t heavy,” Shaw said in a statement shared on social media. “As a mother and a protector of children, I feel deeply saddened for the kids. They are the ones who deserve so much better.”

In her social media post, which included a photo of Shaw locking hands with her husband and two daughters, Shaw said her kids had motivated her to run for state superintendent. Shaw won election to the Chino Valley Unified school board in 2022, fueled by support from conservative parents.

“The problem is that for decades, the same people have had their hands on our education system while our children have continued to fall behind,” Shaw said. “I believe we had an opportunity to change that.”

The office of California superintendent of public instruction is nonpartisan, with no party affiliation listed on the ballot. In past races, it was not unusual for two Democrats to advance to the November election. But this year, endorsements, campaign funding and campaigning broke largely along partisan lines.

Shaw, a Republican and board president of Chino Valley Unified, emerged as the top vote getter in a crowded June primary that featured several Democratic state lawmakers. But she contended in her statement that her race didn’t have the “money or machinery” that her opponent did in the November election.

Shaw trailed Barrera by nearly 15 percentage points, according to the latest election results Thursday morning. Shaw’s campaign raised about $595,000 compared to Barrera’s $812,000. However, the California Teachers Association, the state’s largest teachers union and a heavy spender in state superintendent races, also spent $8.4 million to support Barrera, the board president of San Diego Unified.

That pales in comparison to the combined $50 million raised in the 2018 state superintendent race Tony Thurmond won against Marshall Tuck in 2018. The 2026 state superintendent race had the distinction of featuring two local school board members.

Shaw said she’s not sure what her next steps will be.

“I don’t know exactly what God has next, but I know He isn’t finished,” she said.

Shaw will not be returning to the Chino Valley Unified school board where she began her political career. Her husband, Chris Shaw, ran for her open seat and is trailing his challenger by 11 points, according to the San Bernardino County Register of Voters.

The Wallis Annenberg Wildlife Crossing over the 101 Freeway in Agoura Hills is set to officially open next month, but that hasn’t stopped some wildlife from already using it.

Cameras captured coyote footage twice — once last week and again on Thursday morning — making the mammal the first large animal species seen using the crossing.

“This is amazing — obviously, the wildlife are not waiting for our opening date,” said Beth Pratt, president of the Wildlife Crossing Fund. “The animals are already blessing this crossing and saying, ‘Yep, you got it right.’”

Construction of the expansive bridge began in 2022, aimed at giving wildlife safe passage between the Santa Monica Mountains and Simi Hills after years of research.

Pratt said it’s unclear whether the images of the coyote are of the same animal. The coyote in the most recent image from Thursday morning can be seen on the 101 structure holding a bone or a stick in its mouth.

“The coyote is validating that we got this designed right, and I think that there's something also about a coyote being first — kind of the L.A. mascot next to P-22,” Pratt said.

The National Park Service is installing more cameras along the crossing to document and study how animals use it. While images will be made publicly available, there will not be a livestream.

“We can't, for security reasons, because this is L.A., and if there's a mountain lion going across, somebody's gonna go try to pet it,” Pratt said.

Topline:

• How we got here: Roy held on to a strong lead over McKinney ever since polls closed and is currently ahead by more than twice as many votes. Roy will be a fresh face to the role after the incumbent city attorney, Hydee Feldstein Soto, was ousted in the June primary in a rare defeat of an elected city official. 

• What the candidates had to say: 
  
  • Roy said on social media Wednesday that election night was “a really good night for the people who believe that we should take care of one another, that we can stand up for our rights — even in what feels like an increasingly lawless world — and that we will achieve justice when we fight for it.”
  • McKinney posted on social media Thursday that he’s back in his old office at the Hall of Justice. “The run for City Attorney was an incredible journey, and I’m truly grateful for everyone who believed in me, supported me, and stood by my side,” McKinney wrote. "While I’m disappointed things didn’t turn out the way we hoped, I wouldn’t trade the experience for anything." He acknowledged Roy in a social media video earlier this week, describing her as a “hard worker” who put together a strong coalition of support. McKinney added that he would be “rooting for her.”
  • Neither campaign immediately responded to LAist’s requests for additional comment.
• What’s at stake: The city attorney runs an office of more than 550 lawyers representing L.A. in all legal matters, including filing lawsuits and defending against them. Roy, backed by powerful progressives like U.S. Sen. Bernie Sanders, has vowed to take on the Trump administration in court.

Construction of the green metal fence around MacArthur Park will begin Monday, Nov. 16, with work scheduled to continue through fall 2027.

The city announced the start date Nov. 4, saying crews will install an 8-foot fence around the park’s perimeter. Nearby residents and businesses can expect some noise, dust and vibration during construction, although the city said mitigation measures will be in place.

Crews will work Monday through Friday from 7 a.m. to 3:30 p.m., and the park will remain open while crews are working. 

The fence is the city’s latest attempt to tackle longstanding problems at MacArthur Park, including drug use, homelessness and crime.

The city first approved plans for the fence in October 2025, and the proposal has since drawn both support and criticism from residents and community groups.

Some say they hope the fence will make the park safer, while others question whether it will actually improve conditions there. Police and city officials say the fence will give them more control over the space and make it easier to enforce the law.

Ana Luz Vazquez, a street vendor near MacArthur Park, said her main concern about the fence is what will happen to the unhoused people who stay in the park throughout the day and whether the city plans to address that issue directly.

She is also concerned that construction during the day could affect her ability to work because of traffic, less parking availability and loud noise.

Vazquez said she would prefer construction to take place at night so it would have less of an impact on street vendors.

“If they’re working in the day then how are we supposed to come here and who is going to help us survive,” Vazquez said.

Construction will happen in two phases

Phase 1

• Alvarado St. from W. 6th St. to Wilshire Blvd.
• S. Park View St. from Wilshire Blvd. to W. 6th St.
• Wilshire Blvd. from Alvarado St. to S. Park View St.

Phase 2

• Alvarado St. from Wilshire Blvd. to W. 7th St.
• S. Park View St. from W. 7th St. to Wilshire Blvd.
• Wilshire Blvd. from S. Park View St. to Alvarado St.
• W. 7th St. from Alvarado St. to S. Park View St.

Existing trees will be protected and monitored during the work, according to the Department of Recreation and Parks. Traffic control measures will be in place during work hours, and crews will post temporary “No Parking” signs near active work areas in advance.

Services at the park are expected to remain the same throughout construction. The schedule could change because of weather or other unforeseen circumstances, according to the city.

The city has allocated $2.3 million for the project, but officials have not said whether that will cover the full cost.

After the fence is installed, the city plans a second phase focused on adding decorative elements. Officials have said residents will have an opportunity to provide input on the design.

Residents with questions or concerns about the project can contact Recreation and Parks at RAP.PublicInfo@lacity.org or 213-202-2700.
