Now Trump is blamed for $2bn surge in cost of building reservoir in drought-plagued California

California 's most ambitious water infrastructure project in nearly half a century has just become a whole lot more expensive - and President Donald Trump is being blamed for part of the staggering price surge.
Planners behind the colossal Sites Reservoir, a sprawling basin that could one day provide drinking water to more than 24 million Californians have confirmed that the cost of construction has ballooned from $4.5 billion to at much as $6.8 billion.
And among the reasons cited for the $2 billion spike are the Trump tariffs imposed during the early part of this year which project leaders say are still sending shockwaves through the supply chain.
'The biggest drivers of the increase included factory shutdowns during the Covid-19 pandemic and recent tariffs from President Donald Trump,' Jerry Brown, executive director of the Sites Project Authority (no relation to the former governor), told the Press Democrat.
'Increasing costs are never looked forward to, but they are something that is a fact of life.'
He attributed the jump to inflation for steel, concrete, and other building materials since 2021.
The revelation has ignited fresh political tensions in the Golden State, where Governor Gavin Newsom 's administration has been pushing hard to shore up water infrastructure amid escalating climate extremes.
The Sites project - a reservoir so massive it would stretch 13 miles long and four miles across in Colusa County - is fast becoming a flashpoint in the long-running battle over water, money, and environmental priorities.
Nearly 70 residents in Antelope Valley are expected to lose their homes as the basin swallows up swaths of Colusa County. For them, the price tag isn't measured in billions of dollars, but in broken lives and uprooted communities.
'Scores of people are set to see their homes flooded,' read a previous report on the project's local impact, which has been more than 45 years in the making.
If completed, the Sites Reservoir would become California's eighth-largest, holding 1.5 million acre-feet of water, or nearly 490 billion gallons - intended primarily for use in Southern and Central California, as well as the Bay Area.
Construction is still slated to begin next year with completion by 2033, Brown said.
But rising costs may force tough decisions on funding and prioritization.
Although the Sites project received backing from both Congress and the Biden administration, with nearly $365 million in federal grants over the past three years, the newly projected cost spike has become a political lightning rod particularly as Trump-era tariffs are now being identified as a contributing factor.
On Wednesday, Brown presented the updated cost to the nine-member State Water Commission, which has already set aside $875 million in Proposition 1 bond funds for the project.
Commissioner Daniel Curtin said 22 water agencies have committed planning money, with 16 more on a waiting list seeking extra water capacity.
'The rubber hits the road when the money comes,' Curtin said. 'But it sounds like the commitments are pretty strong.'
Commissioner Jose Solorio added: 'All of the state would benefit from the construction of this project.'
California Republicans have largely avoided commenting on the tariff connection, while environmental groups are using the moment to revive their long-standing opposition to the plan.
'The Sites Reservoir would harm the Sacramento River ecosystem, threaten already imperiled fish species, and release greenhouse gas pollution,' argued a lawsuit filed by conservationists, later dismissed in Yolo County Superior Court.
'The project will cause much environmental harm, which falls on the public, and a small amount of good, which primarily benefits the project investors,' added Stork, senior policy advocate at Friends of the River.
'Among other harms, the reservoir will be a major greenhouse gas emitter. A recent analysis estimated that Sites would emit the equivalent of 80,000 gasoline-powered cars each year.'
Opponents lost their appeal last year, but they aren't backing down. 'It's not surprising,' said Ron Stork, policy director at Friends of the River.
'Large mega-projects typically escalate in costs considerably from their initial estimates. There's a reason why these dams haven't been built yet.'
Stork added, 'We'll have to see if the wealthy urban water districts in Southern California and the Bay Area want to continue to invest in this project.' He estimated that the Sites Reservoir's odds of being built now stand at 'about 50-50.'
The backlash hasn't deterred Governor Newsom, who has thrown his full support behind the project as part of his broader water resilience strategy.
'We are going to need more storage projects with climate change,' said Matt Keller, a spokesperson for the Santa Clara Valley Water District, one of the project's backers. 'Our board is evaluating several different water supply projects from around Northern California and locally, and has been following this one for a while.'
'The longer we wait and the longer it takes to get this done, the more expensive it becomes,' Brown told reporters. 'Even though it is costing more, it is still something we need to do badly.'
He compared Sites to a savings account for future droughts: 'People look at all the water running through rivers in wet winters and say why can't we save more of that?'
Proponents argue that Sites is uniquely positioned to capture 'excess water from major storms' and store it for drier years, which are increasingly common as global temperatures rise.
But for critics, the project epitomizes the high environmental and social cost of mega-infrastructure in an era of climate uncertainty.
'It's very difficult to justify the expense and environmental costs of big surface storage infrastructure projects,' said John Buse, an attorney at the Center for Biological Diversity. 'The Sites Reservoir will cause far more harm than good.'
Ironically, the project's price hike comes after a rare string of wet winters that have filled existing reservoirs to capacity.
Shasta Lake and Lake Oroville both overflowed for a third consecutive year in 2025.
Had the reservoir already existed, Brown noted, Sites could have captured runoff from the past two wet winters. 'It would have filled to the top,' he said, adding that it would have diverted only about 3% of Delta flows during the wettest months.
But experts warn that complacency is dangerous. With California's precipitation increasingly concentrated into short, intense bursts followed by prolonged dry spells, the need for storage remains urgent.
'Water scarcity is always just around the corner,' the project's website warns.
Brown acknowledged that the project has drawn sharp scrutiny - but said history is on its side.
'Rarely when looked back upon 20, 40 or 60 years later are these projects regretted in terms of the benefits to society,' he said. 'These are hard decisions to make as a society, but we are building this for ourselves and future generations.'
