California Governor Gavin Newsom is celebrating a major development in the state’s efforts to expand its water infrastructure, announcing that the Sites Reservoir project has received final approval. The proposed reservoir, located in Glenn and Colusa counties, would become California’s largest new reservoir in 50 years and is intended to help the state prepare for increasingly severe drought conditions.
However, the announcement has been met with skepticism from Californians who questioned whether the project will ever actually reach completion. Several critics have compared the reservoir to California’s troubled high-speed rail project, arguing that the state’s history of delays and rising construction costs gives residents little reason to celebrate just yet.
In the X post above, Newsom announced that the state had secured final approval to move forward with the Sites Reservoir project, which would capture and store water diverted from the Sacramento River during periods of higher flows. The governor also emphasized that construction would create jobs in Glenn and Colusa counties while providing an additional source of water storage for future dry spells.
The reservoir has been discussed for decades as California officials have searched for ways to strengthen the state’s water supply amid recurring droughts and changing weather patterns. Unlike traditional dams built directly across major rivers, Sires Reservoir is designed as an off-stream storage facility that would collect water during wetter periods for use when supplies become limited.
Newsom has connected the project to his administration’s broader efforts to address the effects of climate change on California’s water resources. In an earlier post from June 19, he explained that the state had spent years attempting to accelerate important water infrastructure projects to prepare for a future that could become hotter and drier.
Despite the announcement, receiving regulatory approval does not mean construction has been completed or that the reservoir is ready to supply water to California communities. The project still faces the substantial work of construction and eventual operation, leaving questions about its timeline and final costs as residents wait to see whether the promised benefits materialize.
Comments and Reactions to Gavin Newsom’s Reservoir Announcement
Newsom’s announcement immediately attracted comparisons to California’s high-speed rail project, which has faced years of delays and criticism over its escalating costs, with one commenter writing, “Just like the train to nowhere, this reservoir will never be built.” A different user wrote, “Because your train was such a success.”
Other critics questioned why the reservoir had taken so long to advance, such as one person’s comment that read, “15 years too late because 1,000 homes already burnt.” Another user wrote something similar: “Too little, too late.“
Many of the comments reflect the distrust surrounding Newsom’s announcement as California moves toward construction of a reservoir that supporters believe could strengthen the state’s long-term water security.
