State Water Project

The State Water Project (SWP) is responsible for bringing drinking water to 25 million people and provides irrigation for 750,000 acres of farmland. Without it California would never have become the economic powerhouse it is today.

The nation’s largest state-built water and power development and conveyance system, the SWP diverts water from the Feather River to the Central Valley, South Bay Area and Southern California. Its key feature is the 444-mile long California Aqueduct that can be viewed from Interstate 5.

The SWP has required the construction of 21 dams and more than 700 miles canals, pipelines and tunnels. To reach Southern California, the water must be pumped 2,000 feet over the Tehachapi Mountains; it’s the highest water lift in the world.

Today, about 30 percent of SWP water is used for irrigation, mostly in the San Joaquin Valley, and about 70 percent is used for residential, municipal and industrial use, mainly in Southern California but also in the Bay Area. The SWP was built and is operated by the California Department of Water Resources.

California’s major reservoirs remain nearly full heading into summer

This will be the first time in several years that California will enter summer with the majority of its reservoirs at or over 90 percent of total capacity, according to data from the California Department of Water Resources. As of Saturday, Shasta, Oroville, Folsom, New Bullards Bar, San Luis, Castaic and Cachuma reservoirs are over 90 percent of their total capacity and in the case of Shasta and Oroville are less than 5 percent away from being full. Each of these reservoirs is all well over their historic averages for this time point-in-time of the year. Lake Oroville, which is the second largest reservoir in the state, has a current depth of 895 feet and is storing about 3.47 million acre-feet of water.

News release: In the face of a changing climate, DWR is committed to making investments in forecasting our water supply

As California transitions to a hotter, drier future with greater swings between flood and drought conditions like we’ve seen this past year, DWR is continuing to prepare for the long-term impact on water management. DWR has been and continues to adapt to these extreme weather swings by focusing on advancing our forecasting efforts in order to capture and move as much water as possible during high flow events and managing low flow in drought conditions. This year’s series of atmospheric rivers demonstrated how quickly California can move from one extreme to another, as 3 years of severe drought conditions gave way to flooding and one of the largest snowpacks on record.

Newsom’s Delta Tunnel speed-up plan could hurt region’s fishing, farming, critics say

Gov. Gavin Newsom announced on May 19 a plan to build out California’s clean and green future faster, but some local leaders aren’t thrilled with what it could mean for the controversial Delta Tunnel project. Newsom and the state Department of Water Resources have shown support for the $16 billion project to convey water from the Delta down to southern California, a concept tossed around since the 1980s. The current iteration downsizes the project from two tunnels to one. The governor hopes to speed up construction, expedite court reviews, streamline permitting and California Environmental Quality Act processes and start a climate projects financing program — all to expedite clean infrastructure projects across the state.

Report urges Metropolitan Water District to abandon Newsom’s $16-billion delta tunnel plan

Gov. Gavin Newsom and his administration have touted plans to build a tunnel to transport water beneath the Sacramento-San Joaquin River Delta, saying the project would modernize California’s water infrastructure and help the state adapt to climate change. But an advocacy group is urging the Metropolitan Water District of Southern California to abandon the $16-billion project, saying it doesn’t make financial sense for the state’s largest urban water agency. In a report released this week, the California Water Impact Network said the delta tunnel may seem like a viable alternative but has three major flaws: “an exorbitant price tag, environmental restrictions on operations and the impacts of climate change on deliveries.” … Over the past two decades, the MWD has spent about $240 million on planning for iterations of the proposed tunnel. The agency’s 38-member board has yet to take a vote on whether to support the so-called Delta Conveyance Project.

What to know about California’s boosted water allocations

California’s reservoirs are filled to the brim. Our snowpack is epic. And, in what feels like a near-miraculous turn of events, less than 8 percent of the state is still considered to be in a drought. Another perk of this water bounty: The two biggest water systems that send clean water throughout California will both, for the first time in nearly two decades, deliver all of the water requested by cities, farms and businesses. This is great news for a state that was mired in extreme drought and struggling to survive off reduced water supplies for years. … [I]t doesn’t rain equally across California. So the state has storage and conveyance systems that capture water in its precipitation-blessed far north and northeast regions and transport it through a series of reservoirs, dams, rivers and aqueducts to the rest of the state.

Years of overpumping groundwater aquifers, particularly in the San Joaquin Valley, has caused the land to subside.

If the Delta Conveyance Project had already been constructed, in 2023 the project would have provided zero acre feet of additional water supply, while contractors would have had to pay as much as $1 billion or more to pay for the project this year.  However, you’d never know this based on DWR’s latest misinformation about its Delta tunnel project. … Currently, the State Water Project’s and federal Central Valley Project’s existing pumping plants in the South Delta could be diverting a lot more water than they are today while complying with existing or even stronger environmental regulations. However, for the past several weeks the SWP and CVP have been pumping significantly less water than they are allowed to, because San Luis Reservoir is completely full, meaning there is no place for the CVP and SWP to store additional water diversions.

Wednesday Top of the Scroll: Red alert sounding on California drought, as farmers get less water

A government agency that controls much of California’s water supply released its initial allocation for 2021, and the numbers reinforced fears that the state is falling into another drought. The U.S. Bureau of Reclamation said Tuesday that most of the water agencies that rely on the Central Valley Project will get just 5% of their contract supply, a dismally low number. Although the figure could grow if California gets more rain and snow, the allocation comes amid fresh weather forecasts suggesting the dry winter is continuing. The National Weather Service says the Sacramento Valley will be warm and windy the next few days, with no rain in the forecast.

In a state that depends on large surface water reservoirs to help store water before moving it hundreds of miles to where it is used, a wet year after a long drought has some people yearning for a place to sock away some of those flood flows for when they are needed.
