Gov. Gavin Newsom is raising the stakes on California’s long-running water wars, unveiling the California Water Plan 2028 with a statewide goal to secure 9 million acre-feet of additional water by 2040. That target, roughly equal to two Shasta Reservoirs or enough water for about 18 million homes, is being pitched as a shared scoreboard for conservation, recharge, storage and new infrastructure. State officials say the launch marks a shift from glossy planning documents to measurable follow-through as climate change scrambles the state’s already volatile hydrology.
According to the Governor Newsom's Office, the rollout formally begins the implementation of Senate Bill 72 and orders the Department of Water Resources to modernize the California Water Plan with hard numbers and stronger data for both statewide and watershed-level planning. The 2028 update is branded as an "action-oriented blueprint" meant to line up state, regional and local efforts while leaning on place-specific strategies. The goal is to narrow growing gaps between supply and demand driven by whiplash droughts and storms, and then track who is actually delivering water and who is just talking about it.
"California’s hydrology is changing," Department of Water Resources Director Karla Nemeth said, per Governor Newsom's Office, warning of "extreme wet swings to intensely dry within the same season." Nemeth and other officials say the plan will be built with input from cities, water districts, tribes, labor, environmental justice advocates and local governments so that Sacramento’s big targets do not steamroll local realities. The department is framing the update as a way to knit together science, modeling and watershed-scale data into credible, localized benchmarks, with more detail laid out in its own release.
Joel Metzger, DWR’s deputy director for statewide planning, has dubbed the 2028 update the point where vision meets accountability and says the agency will set measurable targets and deliver real results on the ground. To make that more than a slogan, DWR is standing up an advisory committee to help shape both the 2028 and 2033 updates and has launched a public project hub where meeting materials and timelines will live. The advisory committee, set to hold its first meeting in April, will bring in representatives from across the state; DWR describes the broader rollout and process in its implementation materials.
SB 72 Puts A Clock On California’s Water Playbook
SB 72, authored by Sen. Anna Caballero and signed by Newsom last October, legally requires the modernization of the California Water Plan and bakes the interim 9 million acre-feet target for 2040 into state law, according to the governor’s legislative update. The statute instructs DWR to generate more localized, measurable targets and to report back to the Legislature on progress as the plan is refined. Supporters argue the law creates a level of accountability that will survive whoever comes after Newsom; critics counter that it could lock in numeric goals before local science and environmental needs are fully vetted.
Pushback, Big Projects And Old Fights
The 9 million acre-feet target drops into an already heated fight over which projects should count toward that number, including the Delta Conveyance Project and a slate of proposed reservoir expansions. The Newsom administration has been strongly backing those big-ticket items, while some Delta communities and environmental groups have lined up against them. Reporting in Politico has tracked the governor’s push to fast-track new conveyance and storage options, as well as the political skirmishes over permits and community impacts. How the state ultimately defines what “counts” toward the target, from conservation, recharge and recycling to new conveyance and major reservoirs, will help decide which projects rise to the top and which ones stall out.
What Local Water Managers Are Staring Down
For Bay Area utilities and other local water agencies, the new plan could speed up investments in stormwater capture, groundwater recharge and recycled water, while reshaping who gets grants and how quickly projects move through permits. Reporting in Agri-Pulse highlights DWR’s three main workstreams: better data to balance supply and demand, more localized targets and place-based adaptation actions that are supposed to guide regional strategies. Planners warn that the real test will be money, permits and clear rules on what actually counts toward the 9 million acre-feet goal, which will determine whether this turns into concrete and pipe or just thicker binders on office shelves.
Next on the calendar are public workshops, tribal consultation and technical analyses scheduled for this year, with draft pieces of the 2028 plan expected in 2027 and final adoption targeted for late 2028. Officials are pointing interested parties to DWR’s project hub for meeting dates and materials as the advisory committee gears up for its first session in April. The months ahead will show whether this new target becomes a spark for rapid investment or simply inflames California’s long-running water conflicts.
