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.
Despite the last few storms that brought the North State much needed rain, this water year has been relatively dry, and those conditions are reflected in the Department of Water Resources’ initial State Water Project allocations.
In the universe of California water, Tim Quinn is a professor emeritus. Quinn has seen — and been a key player in — a lot of major California water issues since he began his water career 40 years ago as a young economist with the Rand Corporation, then later as deputy general manager with the Metropolitan Water District of Southern California, and finally as executive director of the Association of California Water Agencies. In December, the 66-year-old will retire from ACWA.
Employees of the state Department of Water Resources, with the help of firefighting crews, were cutting brush and watering down landscapes around Lake Oroville to prevent the 117,000-acre blaze from damaging the reservoir’s infrastructure, including the 770-foot-tall Oroville Dam.
Venture through California’s Central Valley, known as the nation’s breadbasket thanks to an imported supply of surface water and local groundwater. Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.
President Donald Trump on Friday ordered the government to speed up environmental reviews and streamline regulations that he says are hindering work on major water projects in California and other Western states. Trump signed a memorandum aimed at helping the Central Valley Project and the California State Water Project in California, the Klamath Irrigation Project in Oregon and California and the Columbia River Basin system in the Pacific Northwest.
Another attempt by the state Department of Water Resources to have the Butte County District Attorney’s lawsuit against the department thrown out was thwarted Friday. The civil suit stem from the Oroville Dam crisis and the alleged 3.4 billion to 5.1 billion pounds of debris which fell from the collapsing spillway into the Feather River in February 2017.
Nearly six decades ago, shortly after becoming governor, Pat Brown persuaded the Legislature and voters to approve one of the nation’s largest public works projects, the State Water Plan. New reservoirs in Northern California, including the nation’s highest dam at Oroville on the Feather River, would capture runoff from snowfall in the Sierra, and a massive aqueduct would carry water southward to San Joaquin Valley farms and fast-growing Southern California cities.
A local oversight committee will get to have a say as long-term changes are considered for the Oroville Dam, after Sen. Jim Nielsen and Assemblyman James Gallagher recently came to an agreement with the state Department of Water Resources.
A Butte County Superior Court judge will determine where lawsuits against the state Department of Water Resources for the Oroville Dam crisis will be considered in a written ruling. This comes as Judge Tamara Mosbarger heard arguments on Friday from plaintiffs and the defendant.
Splitting California into three new states would scramble nearly every segment of government that touches residents’ lives, from taxes to Medi-Cal to driver’s licenses. … But of all the gargantuan tasks facing Californians should they choose to divide themselves by three — a proposal that has qualified for the November ballot — none is arguably more daunting than carving up the state’s water supply.
A lawsuit filed by Butte County District Attorney Mike Ramsey against the state Department of Water Resources over environmental damages resulting from the Oroville Dam spillway crisis is moving forward in court. Butte County Superior Court Judge Stephen Benson overruled DWR’s demurrer, which is essentially a plea to have a case dismissed, through a written ruling filed on May 31.
The Legislature created the Department of Water Resources in 1956 for the purpose of managing the State Water Project, then in its early stages of planning. … AB 3045 would create a new State Water Project Commission under the state’s Natural Resources Agency to run the project – the agency, whose secretary serves in the governor’s cabinet, has broad authority over DWR.
The California Department of Water Resources announced Monday this year’s allocation has been raised to 35 percent of full distribution, or 1.48 million acre-feet of water statewide. (One acre foot is enough to cover one acre of land with a foot of water.) As of last month, the agency planned to distribute only 30 percent of normal.
We traveled deep into California’s water hub and traverse the Sacramento-San Joaquin Delta, a 720,000-acre network of islands and canals that supports the state’s water system and is California’s most crucial water and ecological resource. The tour made its way to San Francisco Bay, and included a ferry ride.
The Federal Emergency Management Agency recently told north state congressmen Doug LaMalfa and John Garamendi that the agency is still reviewing whether the state Department of Water Resources is eligible for further reimbursement to fix the Oroville Dam spillway.
A bill proposed by Assemblyman James Gallagher which would take the State Water Project out of the hands of the state Department of Water Resources passed unanimously on Tuesday through a legislative committee. Assembly Bill 3045 passed 15-0 through the Assembly Water, Parks, and Wildlife Committee and is now headed to the Assembly Appropriations Committee.
There are 34 storage facilities, 30 dams, 23 pumping plants and nine hydroelectric power generation plants that are part of the California State Water Project, and the Department of Water Resources is in charge of not only operating but also of inspecting all of them. Local Assemblyman James Gallagher says that’s a conflict of interest, and a bill he’s pushing looks to take some of that authority away from DWR.
The nearly 30 contractors that are part of the State Water Project are expected to receive 30 percent of the water they have requested for 2018 – up from January’s estimate of 20 percent – according to the Department of Water Resources. DWR Director Karla Nemeth stated in a news release that late precipitation and snow in March contributed to the rise in projected allocations.
While some construction continues at Oroville Dam, the bulk of work under phase two is expected to begin May 8, state Department of Water Resources officials said Wednesday in a monthly media update call. This comes as DWR submitted an updated 2017-2018 Lake Oroville operations plan on Tuesday to the Federal Energy Regulatory Commission and the California Division of Safety of Dams for approval.
Oroville Dam operators said Tuesday they may have to release water over a partially rebuilt spillway for the first time since repairs began on the badly damaged structure last summer. Department of Water Resources officials said anticipated storms could trigger releases this week or next.
The storms of March may not have rained glory on the state, but they dropped enough snow on the Sierra to greatly improve the drought situation and, with another storm rolling in this week, water resources officials believe thirsty California will make it through the year.

Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.
State Parks workers were pulling cable up a launch ramp at Bidwell Marina Thursday because the water level in Lake Oroville is on the rise. March’s storms have brought the lake level up almost 13 feet since the start of the month, according to the Department of Water Resources website.
After a historically wet season last year, relatively little precipitation has fallen this year in California during two of the three historically wettest months. Officials are urging stricter water conservation and caution drier months ahead. After last week’s rains, the Sierra snowpack — a critical factor in water availability — climbed to just 39 percent of normal.
California water officials tromped through long-awaited fresh snowdrifts in the Sierra Nevada mountains Monday, but a welcome late-winter storm still left the state with less than half the usual snow for this late point in the state’s important rain and snow season.
The storm that wrought avalanches at ski resorts and whiteouts on mountain roads last week was so fierce that California water officials postponed their much-anticipated monthly survey of snow depth, setting the stage for potentially better news this week.
Welcome drifts of fresh snow await California’s water managers on their late-winter survey of the vital Sierra Nevada snowpack Monday after a massive winter storm slowed the state’s plunge back into drought. The storm piled snow by the foot in the mountains, forcing Department of Water Resources officials to postpone the measurement for a few days.
Dams and reservoirs under the jurisdiction of the California Department of Water Resources will be inspected more regularly thanks to a new law Gov. Jerry Brown signed this week. What does this mean for Tulare County’s reservoirs and aging dams, Kaweah and Success?
Locals who lost business or saw their property value decrease because of the Oroville Dam crisis are anxious to be reimbursed through a class action lawsuit filed last week. … There is a variety of plaintiffs in the class action lawsuit, including a child care facility, a water ski shop, a ranch and a ministry.
A year ago, nearly 200,000 Northern California residents were alarmed by an alert from the state Department of Water Resources informing them of the potential failure of the auxiliary spillway at the Oroville Dam. … Everything department officials do at the Oroville Dam affects our [state Sen. Jim Nielsen] community — from the water level to the outflow.

The Board of Supervisors, acting as directors of the Water Agency, unanimously agreed to reinstate Davis, commending him as a trusted leader with a proven track record in the area.
Get a unique view of the San Joaquin Valley’s key dams and reservoirs that store and transport water on our March Central Valley Tour.
Our Central Valley Tour, March 14-16, offers a broad view of water issues in the San Joaquin Valley. In addition to the farms, orchards, critical habitat for threatened bird populations, flood bypasses and a national wildlife refuge, we visit some of California’s major water infrastructure projects.
Critics who say state water policy tilts too far toward Southern California got additional ammunition last week, when Gov. Jerry Brown named a new director to run his Department of Water Resources. New DWR Director Karla Nemeth is married to Tom Philp, an executive strategist with the Metropolitan Water District of Southern California.
An investigation into last winter’s near catastrophe at Oroville Dam uncovered a litany of problems with how the dam was built and maintained, but one of them stands out: Even as workers built the dam, they were raising alarms about the eroded, crumbling rock on which they were directed to lay concrete for the 3,000-foot-long main flood control spillway.
The city of Oroville filed a lawsuit against the state Department of Water Resources Wednesday which alleges fabricated maintenance reports, racial discrimination and decades of mismanagement led to the Oroville Dam spillway failure last February.
A lawsuit filed Wednesday against the state water agency in charge of the Oroville Dam not only alleges mismanagement and disregard for the public’s safety, but also a toxic work environment rife with racism, sexual harassment and theft.
Faced with a shortage of money and political support after seven years of work, Gov. Jerry Brown’s administration is working on a plan to scale back one of his key legacy projects, a $17 billion proposal to build two massive tunnels under the Sacramento-San Joaquin River Delta to make it easier to move water from Northern California to the south.
The grassy brown Sierra meadow where California’s water managers gave the results of the winter’s first manual snowpack measurements Wednesday told the story — the drought-prone state is off to another unusually dry start in its vital winter rain and snow season. “We would like to have had more snow,” Grant Davis, head of California’s Department of Water Resources, told news crews gathered in this mountain field, bare of all but a few crusty dots of old snow.
We ventured through California’s Central Valley, known as the nation’s breadbasket thanks to an imported supply of surface water and local groundwater. Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.
The state Department of Water Resources on Thursday, Nov. 30, announced an initial water allocation of 15 percent for most of its State Water Project contractors for 2018. The low percentage is a conservative figure, which is typical of the department’s early season forecast.
Phase two of construction at Oroville Dam — with work on both spillways — might prove more challenging than the first feat, the contractor’s project director said in a media call Thursday. … DWR [California Department of Water Resources] will hold two community meetings next week.
Oroville’s mayor said Thursday she knew about cracks in the replacement spillway at the troubled dam nearby and is not concerned, but heaped criticism on state water officials for failing to communicate with her town. Linda Dahlmeier said the Department of Water Resources should have proactively communicated that cracks were expected but has instead created a “firestorm” in a community that was rattled by sudden evacuation orders last February.
California’s wettest months of the year are still to come, but the state’s largest water reservoirs already appear to be in decent shape. As of Nov. 27, most of California’s major reservoirs were above their historical averages for this time of year, according to the Department of Water Resources.
Hairline cracks have been detected in sections of the newly reconstructed flood-control spillway at Oroville Dam. State and federal officials said they’re confident the cracks don’t pose a safety problem and don’t need to be repaired.
This tour explored the Sacramento River and its tributaries through a scenic landscape as participants learned about the issues associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of California’s water and feed into two major projects: the State Water Project and the federal Central Valley Project. Tour participants got an on-site update of repair efforts on the Oroville Dam spillway.
For as long as agriculture has existed in the Central Valley, farmers have pumped water from the ground to sustain their livelihood and grow food consumed by much of the nation. This has caused the ground in certain places to sink, sometimes dramatically, eliminating valuable aquifer storage space that can never be restored.
The Oroville Dam flood control spillway has been fixed. … In addition, [state Department of Water Resources Director Grant] Davis said “repairs and updates” are already being made at some of the 93 other dams around California where the state ordered intensive inspections in the wake of the Oroville crisis.
California is launching an overall safety review of the nation’s tallest dam to pinpoint any needed upgrades in the half-century-old structure, water officials said Wednesday, launching the kind of overarching review called for by an independent national panel of experts in September following the collapse of two spillways at Oroville Dam.
Survey results largely showed that respondents weren’t happy with how things went down this past February at the Lake Oroville spillways and the events that followed. Most respondents expressed their concerns were with the California Department of Water Resources.
The state Department of Water Resources intends to open the spillway boat launch ramp after construction at the dam is complete, but there is a possibility it will stay out of commission, according to a department official. The spillway boat launch is the largest on the lake, with up to 12 lanes when the water is high enough.
With just more than two weeks until the initial reconstruction of the main spillway at Lake Oroville is supposed to be completed, the Department of Water Resources released operations plan for the reservoir for this coming flood season.
In February, a huge hole opened in the Lake Oroville main spillway. The cause of the hole is still undetermined. … State and federal agencies devised a plan to quickly repair or replace the structures at the lake.
For months, regional water officials were prevented from recharging drought-depleted water basins in the San Gabriel Valley and southeast Los Angeles County because they feared an infestation of an invasive shellfish that could destroy local ecosystems.
Like every autumn, October is bringing cooler weather, changing leaves and pumpkins to fields across California. But unlike the past five years, when a historic drought gripped the state, there’s something new across the landscape: full reservoirs.
Repairs to the Oroville Dam spillway are on track for the Nov. 1 deadline, state Department of Water Resources representatives say, but work will be far from over then.
Bad design and construction of the tallest U.S. dam a half-century ago and inadequate state and federal oversight since then led to a disastrous spillway collapse in February, an independent national team of dam safety experts said Tuesday as they urged tougher safety reviews nationwide.
State dam operators have issued a new report that refutes troubling allegations raised by a catastrophic engineering expert who contends Oroville Dam may be dangerously leaking.
Slowly – but surely – we are learning that the near-catastrophic failure of Oroville Dam’s main spillway wasn’t truly caused by weather, even though the state claims that in seeking federal aid for repairs. Rather, it resulted from poor engineering and construction when the nation’s highest dam was rising more than a half-century ago as the centerpiece of the State Water Project, and poor maintenance since its completion.
California Gov. Jerry Brown last week appointed Grant Davis as director of the state’s Department of Water Resources. Davis, 54, general manager of the Sonoma County Water Agency, brings an unusual resume to the job. … Davis assumes the DWR director’s job on Aug. 1, and Water Deeply recently talked to him about his plans.
Grant Davis, general manager of the Sonoma County Water Agency, was tapped Wednesday by Gov. Jerry Brown as the state’s new director for the Department of Water Resources, handing a veteran of North Bay politics and water policy a central role in Brown’s controversial bid to overhaul California’s water system with a $17 billion pair of tunnels under Sacramento-San Joaquin Delta.
The Golden State’s system of 154 major reservoirs is holding 34,464,000 acre-feet according to the most recent June 12 state report with data pulled from an array of entities that own and manage these bodies of water, including the Department of Water Resources, the Bureau of Reclamation, the Army Corps of Engineers and several city water departments.
