Reclamation announces initial 2024 water supply allocations for Central Valley Project contractors

SACRAMENTO, Calif. – Today, the Bureau of Reclamation announced initial 2024 water supply allocations for Central Valley Project water users. Water supply allocations are based on an estimate of water available for delivery to Central Valley Project water users and reflect current reservoir storage, precipitation, and snowpack in the Sierra Nevada.

“The wet hydrologic conditions we experienced during the 2023 water year left most of our reservoirs in good shape as we progressed to the 2024 water year,” said California-Great Basin Regional Director Karl Stock. “Precipitation totals this water year started off slowly, evidenced by the fact we were well below average at the time of the Feb. 1 water supply forecast. Since that time, several storms have boosted the Sierra Nevada snowpack, bringing us to near normal conditions for Northern California. It is likely we will see the water supply benefits from these storms in the March 1 forecast update. At the same time, we have to be prepared for and respond accordingly to the possible re-emergence of drier conditions.”

New Melones 82 1,977 138
Millerton 63 330 110
San Luis (federal share) 93 896 137

Based on current hydrology and forecasting, Reclamation is announcing the following initial Central Valley Project water supply allocations:

North-of-Delta Contractors

Sacramento River

  • Irrigation water service and repayment contractors north-of-Delta are allocated 75% of their contract total.
  • Municipal and industrial water service and repayment contractors north-of-Delta are allocated 100% of their historical use.
  • Sacramento River Settlement Contractors’ water supply is based upon settlement of claimed senior water rights. The 2024 water year is determined as non-critical, as defined in their Settlement Contracts, which allows for 100% of their contract water supply.

American River

  • M&I water service and repayment contractors north-of-Delta who are serviced by Folsom Reservoir on the American River are allocated 100% of their contract total.

In-Delta Contractors

  • M&I water service and repayment contractors who are serviced directly from the Delta are allocated 100% of their contract total.

South-of-Delta Contractors

  • Irrigation water service and repayment contractors south-of-Delta are allocated 15% of their contract total.
  • M&I water service and repayment contractors south-of-Delta are allocated 65% of their historical use, or public health and safety needs, whichever is greater.
  • San Joaquin River Settlement Contractors and San Joaquin Exchange Contractors’ water supply is based upon settlement/exchange of claimed senior water rights. The 2024 water year is determined as non-critical, as defined in their contracts, which allows for 100% of their contract supply.
  • In addition to this allocation, Central Valley Project contractors south-of-Delta have been approved to reschedule approximately 184,000 acre-feet of unused allocated water from 2023 for use in 2024.

Eastside Water Contractors

  • Eastside water service contractors (Central San Joaquin Water Conservation District and Stockton East Water District) will receive 100% of their contract total.

Friant Division Contractors

  • Friant Division contractors’ water supply is delivered from Millerton Reservoir on the upper San Joaquin River via the Madera and Friant-Kern canals. The first 800,000 acre-feet of available water supply is considered Class 1; Class 2 is considered the next amount of available water supply up to 1.4 million acre-feet. The Friant Division water supply allocation is 60% of Class 1 and 0% of Class 2.

Wildlife Refuges

  • The 2024 water year is determined as non-critical, as defined in their contracts, which allows for 100% of contract supply for wildlife refuges (Level 2), both north- and south-of-Delta.

In recognition of recent efforts to develop a south-of-Delta drought plan, Reclamation is reserving approximately 83,000 acre-feet of water currently in San Luis Reservoir that will contribute to a drought reserve pool and is not considered as a volume of water available for water supply allocations.

As the water year progresses, changes in hydrology, actions that impact operations, and opportunities to deliver additional water will influence future allocations. Reclamation will continue to monitor hydrology and may adjust basin-specific allocations if conditions warrant an update. Water supply updates are posted on Reclamation California-Great Basin Region’s website.

SACRAMENTO, Calif. – Today, the Bureau of Reclamation announced initial 2023 water supply allocations for Central Valley Project water users. Water supply allocations are based on an estimate of water available for delivery to CVP water users and reflect current reservoir storage, precipitation, and snowpack in the Sierra Nevada.

“While we are cautiously optimistic, we are also cognizant of the uncertainties that exist and the fluctuating nature of California’s climate with the possibility that dry conditions will return,” said Reclamation Regional Director Ernest Conant. “We received a much-needed dose of rain and snow in December and January that helped boost the water levels at our CVP reservoirs. The projected runoff from the snowmelt later this year will further benefit the state as we head into the summer months. However, we are all too aware of the precarious nature of recent weather patterns and must proceed prudently as we move through the water year—especially with below average storage in the state’s largest reservoir, Shasta.”

This year’s initial allocations reflect the improved hydrologic conditions caused by the winter storms that left the Sierra Nevada snowpack at well above normal conditions. However, not all river basins were equally improved, highlighting the need that late winter and early spring rain and snow are still needed. Adequate water elevations in Shasta Reservoir are crucial to ensuring deliveries to agricultural contractors and wildlife refuges. It also ensures enough cold water exists for spawning salmon later in the year.

Currently, reservoir storages in Trinity and Shasta reservoirs are below the historic average for this time of year and runoff forecasts indicate that overall storage for these reservoirs may be limited if substantial spring precipitation does not materialize. Other CVP reservoirs, such as Folsom and Millerton, are in better shape with above average water storage levels for this time of year.

Folsom 54 525 111
New Melones 44 1,059 77
Millerton 51 266 101
San Luis (federal share) 64 618 95

“Three years of record-setting drought in California will take some time to recover from,” said Reclamation Regional Director Conant. “In the short-term, the early winter storms have helped, but in the long-term, we still have much catching up to do, especially in the northern part of our system.”

Based on current hydrology and forecasting, Reclamation is announcing the following initial CVP water supply allocations:

North-of-Delta Contractors 

Sacramento River 

  • Irrigation water service and repayment contractors north-of-Delta are allocated 35% of their contract total.
  • Municipal and industrial water service and repayment contractors north-of-Delta are allocated 75% of their historic use or public health and safety needs, whichever, is greater.
  • Sacramento River Settlement Contractors’ water supply is based upon settlement of claimed senior water rights. The 2023 water year is currently determined as non-critical, as defined in their Settlement Contracts, which allows for 100% of their contract supply.

American River 

  • M&I water service and repayment contractors north-of-Delta who are serviced by Folsom Reservoir on the American River are allocated 75% of their historical use.

In-Delta Contractors 

  • M&I water service and repayment contractors who are serviced directly from the Delta are allocated 75% of their historical use.

South-of-Delta Contractors 

  • Irrigation water service and repayment contractors south-of-Delta are allocated 35% of their contract total.
  • M&I water service and repayment contractors south-of-Delta are allocated 75% of their historical use.
  • San Joaquin River Settlement Contractors and San Joaquin Exchange Contractors’ water supply is based upon settlement/exchange of claimed senior water rights. The 2023 water year is currently determined as non-critical, as defined in their contracts, which allows for 100% of their contract supply.

Eastside Water Contractors 

  • Eastside water service contractors (Central San Joaquin Water Conservation District and Stockton East Water District) will receive 100% of their contract total.

Wildlife Refuges 

  • The 2023 water year is currently determined as non-critical, as defined in their contracts, which allows for 100% of contract supply for wildlife refuges (Level 2), both north- and south-of-Delta.

Friant Division Contractors 

  • Friant Division contractors’ water supply is delivered from Millerton Reservoir on the upper San Joaquin River via the Madera and Friant-Kern canals. The first 800,000 acre-feet of available water supply is considered Class 1; Class 2 is considered the next amount of available water supply up to 1.4 million acre-feet. Given the current hydrologic conditions, the Friant Division water supply allocation is 100% of Class 1 and 20% of Class 2.

As the water year progresses, changes in hydrology, actions that impact operations, and opportunities to deliver additional water will influence future allocations. Reclamation will continue to monitor hydrology and may adjust basin-specific allocations if conditions warrant an update. Water supply updates are posted on Reclamation California-Great Basin Region’s website.

Reclamation urges Central Valley Project contractors to prepare for potential fourth dry year

Action comes amid the worst three-year drought period on record

Media Contact: Mary Lee Knecht (916) 978-5100 mknecht@usbr.gov
For Release: Nov 28, 2022

Sacramento, Calif. – The Bureau of Reclamation is asking its contractors receiving Central Valley Project water for municipal and industrial use to begin planning for potentially extremely limited water supply conditions in 2023. Despite the early storms that California experienced this month, drought conditions continue. Conservative planning efforts will help better manage the limited water resources in the event conditions remain dry and we move into a fourth consecutive drought year.

The Central Valley Project began the 2023 water year on October 1 with water storage reservoirs near historic lows. Shasta Reservoir, the state’s largest reservoir and cornerstone of the Central Valley Project, is currently at 31% capacity. If drought conditions extend into 2023, Reclamation will find it increasingly difficult, if not impossible, to meet all the competing needs of the Central Valley Project without beginning the implementation of additional and more severe water conservation actions.

Under Reclamation’s Municipal & Industrial Water Shortage Policy, Central Valley Project municipal and industrial contractors are asked to provide specific information to calculate public health and safety numbers using the standard calculation outlined in the Central Valley Project Municipal and Industrial Water Shortage Policy Guidelines and Procedures.

Reclamation continues to closely monitor hydrologic conditions and will provide regular updates in the coming months. Initial water supply allocations for the Central Valley Project will be announced in February.

Central Valley Project begins 2023 water year with 3.6 million acre-feet of storage

SACRAMENTO, Calif. – After a third straight year of severe drought, the Bureau of Reclamation’s Central Valley Project begins the 2023 water year with 3.6 million acre-feet of water in storage — one of the lowest starting points in recent years. The CVP’s major reservoirs are (from north to south) Trinity, Shasta, Folsom, New Melones, Millerton, and the federal share of San Luis Reservoir. The water year begins Oct. 1 each year and ends Sept. 30.

“The 2022 water year was wetter than 2020 and 2021 in some areas of the state, but it was still well below average and came on such a large water supply deficit that it earned the title as the worst three-year drought on record with some of the driest winter months on record,” said Ernest Conant, regional director of the California-Great Basin region. “In order to navigate through this record-breaking drought, we had to modify operations outside of those considered in previous droughts and take a fresh look at every component of the CVP including facilities, contractors and environmental requirements.”

The 2022 water year began with an atmospheric river that brought record rain to Northern California in October 2021. That was a followed by a blast of winter storms in December that produced more than 6 feet of Sierra snow by the end of the month. Then, the storm door slammed shut, ushering three months of record dryness in northern California. The snowpack, vital to the state’s water supply, was virtually non-existent by April 1.

Reclamation responded with a 0% allocation to CVP agricultural contractors, an agreement to significantly reduce releases from Shasta and Trinity reservoirs to prioritize storage conservation and temperature management, reducing deliveries to Sacramento River Settlement Contractors, and releasing water from Friant Dam to fulfill obligations to senior water right holders, the San Joaquin River Exchange Contractors.

The table below shows reservoir capacities and end-of-year storage amounts for water years 2021 and 2022 for major CVP reservoirs. The following table compares end-of-year storages from water year 2017 to 2021. The amount of stored water at the end of the water year reflects the amount carried over into the new water year.

In anticipation of continued drought in 2023, Reclamation will pursue a water management strategy that emphasizes providing supplies for health and safety needs; maintaining suitable water quality in the Delta, which is the source of municipal drinking water for many communities; protecting species by meeting environmental requirements; conserving storage to meet future critical needs; and urban and agricultural water supplies.

The CVP is the largest single source of irrigation water in California, typically supplying water to about 3 million acres of agricultural land in the San Joaquin and Sacramento valleys. The CVP also provides urban water for millions of people and industrial water, including that essential to the San Francisco Bay Area’s economy. Water from the CVP is also vital for the environment, wildlife and fishery restoration, including providing water to 19 refuges in the Central Valley, and hydroelectric power production.

During the 2022 water year, CVP powerplants generated about 2 billion kilowatt-hours, very much below an average year of about 4.5 billion kilowatt-hours. Project use is anticipated to have consumed about 20 percent of this energy; the remaining energy was made available to public agency contractors serve by the Western Area Power Administration.

Reclamation continues to work with federal and state partner agencies and CVP water and power customers to prepare for potentially ongoing drought conditions. Another consecutive dry water year will require conservative planning and assertive multiagency action.

Sacramento, Calif. – Today, the Bureau of Reclamation announced initial 2022 water supply allocations for Central Valley Project contractors. Allocations are based on an estimate of water available for delivery to CVP water users and reflect current reservoir storages, precipitation, and snowpack in the Central Valley and Sierra Nevada. This year’s low allocations are an indicator of the third consecutive dry year California is experiencing and will be updated if conditions warrant.

“We began the 2022 water year with low CVP reservoir storage and some weather whiplash, starting with a record day of Sacramento rainfall in October and snow-packed December storms to a very dry January and February, which are on pace to be the driest on record,” said Regional Director Ernest Conant. “Further, the December storms disproportionately played out this year in the headwaters—heavy in the American River Basin and unfortunately light in the upper Sacramento River Basin, which feeds into Shasta Reservoir, the cornerstone of the CVP.”

Currently, CVP reservoir storage is below the historic average for this time of year and runoff forecasts predict that overall storage will be limited if substantial spring precipitation does not materialize. California Department of Water Resources’ forecast update from Feb. 1 to Feb. 15 shows a total decrease in projected annual inflow to Shasta, Oroville, Folsom, and New Melones reservoirs of 1.2 million acre-feet. Without significant precipitation, this may continue to decrease further.

“Losing over a million acre-feet of projected inflow in two weeks’ time is concerning,” said Regional Director Conant. “We’ve got our work cut out for us this year; strengthened collaboration and coordination among agency partners, water and power users, and stakeholders will be instrumental.”

Based on current hydrology and forecasting, Reclamation is announcing the following initial CVP water supply allocations:

North-of-Delta Contractors

Sacramento River

  • Irrigation water service and repayment contractors north-of-Delta are allocated 0% of their contract total.
  • Municipal and industrial water service and repayment contractors north-of-Delta will be provided water for public health and safety needs consistent with the CVP M&I Water Shortage Policy.
  • Sacramento River Settlement Contractors’ water supply is based upon settlement of claimed senior water rights and the 2022 water year is currently designated as a critical year, as defined in their Settlement Contracts.

          American River

  • M&I water service and repayment contractors north-of-Delta who are serviced by Folsom Reservoir on the American River are allocated 25% of their historical use.

In-Delta Contractors

  • M&I water service and repayment contractors who are serviced directly from the Delta are allocated 25% of their historical use.

South-of-Delta Contractors

  • Irrigation water service and repayment contractors south-of-Delta are allocated 0% of their contract total.
  • M&I water service and repayment contractors south-of-Delta are allocated 25% of their historical use.
  • For San Joaquin River Exchange Contractors and San Joaquin Settlement Contractors, the 2022 water year is currently designated as a critical year, as defined in their contracts.

Wildlife Refuges

  • For water supply for wildlife refuges (Level 2), north- and south-of-Delta, the 2022 water year is currently designated as a critical year, as defined in their contracts.

Friant Division Contractors

  • Friant Division contractors’ water supply is delivered from Millerton Reservoir on the upper San Joaquin River via the Madera and Friant-Kern canals. The first 800,000 acre-feet of available water supply is considered Class 1; Class 2 is considered the next amount of available water supply up to 1.4 million acre-feet. Given the current hydrologic conditions, the Friant Division water supply allocation is 15% of Class 1 and 0% of Class 2.

Water supply allocations for Eastside irrigation and M&I water service and repayment contractors will be announced in May per their contracts.

M&I contractors whose water service and repayment contracts cite the CVP M&I Water Shortage Policy may request a public health and safety adjustment within 30 days of initial allocations consistent with that policy.

As the water year progresses, changes in hydrology and opportunities to deliver additional water will influence future allocations. Reclamation will continue to track hydrology and may adjust basin-specific allocations if conditions warrant an update. Water supply updates are posted on Reclamation California-Great Basin Region’s website.

SACRAMENTO, Calif. — Today, the Bureau of Reclamation announced the initial 2021 water supply allocation for Central Valley Project contractors. Allocation amounts are based on an estimate of water available for delivery to CVP water users and reflects current reservoir storages, precipitation, and snowpack in the Central Valley and Sierra Nevada. This year—s low allocation is an indicator of the dry winter California is experiencing after the dry water year of 2020.

—Although we had a couple of precipitation-packed storms in January and early February, we are still well below normal for precipitation and snowfall this year,— said Regional Director Ernest Conant. —We will monitor the hydrology as the water year progresses and continue to look for opportunities for operational flexibility.—

The California Department of Water Resources reports that as of Feb. 21, statewide average snow water content in the Sierra Nevada was 54% of the Apr. 1 average. Current Northern Sierra precipitation is 52% of the seasonal average to date.

Shasta Reservoir—s 4.5 million acre-feet capacity represents the majority of CVP water storage. Water from Shasta Reservoir is used for many purposes, including contractor supply for north and south of the Sacramento-San Joaquin River Delta, as well as maintaining temperatures downstream of the dam throughout the summer and fall for threatened and endangered fish species to the extent practicable. Currently, reservoir storage is below the historic average for this time of the year and runoff forecasts predict that overall storage might be limited if typical spring precipitation does not materialize.

Given the low snowpack and low projected runoff this spring and summer, Reclamation is announcing the following initial allocations:

North-of-Delta Contractors (Including American River and In-Delta Contractors)

Agricultural water service contractors north-of-Delta are allocated 5% of their contract supply.
Pursuant to Reclamation—s municipal and industrial water shortage guidelines, M&I water service contractors north-of-Delta (including American River and In-Delta Contractors) are allocated 55% of their historic use or public health and safety needs, whichever is greater.
Sacramento River Settlement Contractors are allocated 75% of their contract supply.
Eastside Water Service Contractors

Eastside water service contractors (Central San Joaquin Water Conservation District and Stockton East Water District) are allocated 100% of their contract total.
South-of-Delta Contractors

Agricultural water service contractors south-of-Delta are allocated 5% of their contract supply.
M&I water service contractors south-of-Delta are allocated the greater of 55% of their historic use or public health and safety needs, whichever is greater.
The San Joaquin River Exchange Contractors and San Joaquin Settlement Contractors are allocated 75% of their contract supply.
Wildlife Refuges

Wildlife refuges (Level 2) north- and south-of-Delta, which also have allocations subject to pre-established Shasta inflow criteria, are allocated 75% of their contract supply.
Friant Division

Friant Division contractors— water supply develops in the Upper San Joaquin River Basin Watershed and is delivered from Millerton Lake through Friant Dam to the Madera Canal and Friant-Kern Canal. The first 800,000 acre-feet of available water supply is considered Class 1; Class 2 is considered the next amount of available water supply up to 1.4 million acre-feet. Given the current hydrologic conditions, Friant Class 1 initial allocation will be 20% and Class 2 will be 0%.
For the San Joaquin River Restoration Program, Reclamation is currently forecasting a —Dry— water year type, providing for 170,732 acre-feet to be used for Restoration Program purposes.
In addition to the initial 2021 CVP water allocation, several south-of-Delta and Friant Division contractors are rescheduling unused water from 2020 supplies into 2021. That water is being stored in San Luis Reservoir and Millerton Lake. The option to reschedule (carry over) water in San Luis Reservoir and Millerton Lake from one contract year to the next has been available to the water service contractors since the early 1990—s. That carry over option was instituted after a series of dry years in the early 1990—s to encourage conservation and best water management practices.

Reclamation notified the Sacramento River Settlement Contractors, San Joaquin River Exchange Contractors, San Joaquin Settlement Contractors, and Refuge Contractors that the forecasted inflow to Shasta Lake falls below the threshold and the water year is currently identified as a —Critical Year— as that term is defined in their contracts.

As the water year progresses, changes in hydrology and opportunities to deliver additional water will influence future allocations. Water supply updates will be made as appropriate and posted at https://www.usbr.gov/mp/cvp-water/index.html.

Reclamation outlines Central Valley Project initial 2020 water allocation

Media Contact: Shane Hunt, 916-978-5100, mppublicaffairs@usbr.gov

For Release: February 25, 2020    ////   https://www.usbr.gov/newsroom/newsrelease/detail.cfm?RecordID=69603

Sacramento, Calif. – The Bureau of Reclamation today announced the initial 2020 water supply allocation for Central Valley Project contractors. Allocation amounts are based on an estimate of water available for delivery to CVP water users and reflects current reservoir storages, precipitation, and snowpack in the Central Valley and Sierra Nevada.

“Today’s allocation comes on the heels of an operations plan signed last week, underscoring the Trump administration’s commitment to bringing a sustainable and reliable water supply to California’s Central Valley. While that operations plan is based on the best available science and maximizes water supplies, we still face significant uncertainty due to legal challenges,” said Reclamation Commissioner Brenda Burman. “Despite the hurdles brought on by litigation from the state and others, we remain committed to providing reliable water for families, farms, cities and the environment.”

California benefited from wet weather and significant snowpack in late 2019, but precipitation and snowpack have been below average so far in 2020. The California Department of Water Resources reports that as of February 24, statewide average snow water content in the Sierras was just 41% of the April 1 average. Current Northern Sierra precipitation is about 51% of the seasonal average.

“After a promising start to our precipitation season, January and February turned much drier than average,” said Reclamation’s California-Great Basin Regional Director Ernest Conant. “Fortunately, our project reservoirs are still hovering above average thanks to the wet winter last year, but with little precipitation in the forecasts, we must remain cautious with supplies and allocations this early in the year.”

Shasta Reservoir’s 4.5 million acre-feet capacity represents the majority of CVP water storage. Water from Shasta is used for many purposes, including contractor supply for north and south of the Sacramento-San Joaquin River Delta, as well as ensuring adequate temperatures can be maintained downstream of the dam throughout the summer and fall for threatened and endangered species. Currently, reservoir storage is above the historic average for this time of the year. However, runoff forecasts still predict that overall storage might be limited if typical spring precipitation does not materialize.

“While we’re constrained by the water nature provides, our new CVP operations plan will improve operations to maximize water supplies,” Conant said. “We recognize the importance of providing meaningful allocations early in the year, especially for our agricultural contractors’ planning needs.”

Given the low snowpack and low projected runoff this spring and summer, Reclamation is announcing the following initial allocations:

North-of-Delta Contractors (Including American River and In-Delta Contractors)

  • Agricultural water service contractors North-of-Delta are allocated 50% of their contract supply.
  • Pursuant to Reclamation’s M&I water shortage guidelines, M&I water service contractors North-of-Delta (including American River and In-Delta Contractors) are allocated 75% of their historic use or public health and safety needs.
  • The Sacramento River Settlement Contractors are allocated 100% of their contract supply.

Eastside Water Service Contractors

  • Eastside water service contractors (Central San Joaquin Water Conservation District and Stockton East Water District) will receive 100% of their contract total.

South-of-Delta Contractors

  • Agricultural water service contractors South-of-Delta are allocated 15% of their contract supply.
  • M&I water service contractors South-of-Delta are allocated the greater of 65% of their historic use or public health and safety needs.
  • The San Joaquin River Exchange Contractors and San Joaquin Settlement Contractors are allocated 100% of their contract supply.

Wildlife Refuges

  • Wildlife refuges (Level 2) North- and South-of-Delta, which also have allocations subject to pre-established Shasta inflow criteria, are allocated 100% of their contract supply of 422,000 acre-feet.

Friant Division

  • Friant Division contractors’ water supply develops in the Upper San Joaquin River Basin Watershed and is delivered from Millerton Lake through Friant Dam to the Madera Canal and Friant-Kern Canal. The first 800,000 acre-feet of available water supply is considered Class 1; and Class 2 is considered the next amount of available water supply up to 1.4 million acre-feet. Given the current hydrologic conditions, Reclamation determined that Friant Class 1 initial allocation will be 20% and Class 2 will be 0%.
  • For the San Joaquin River Restoration Program, Reclamation is currently forecasting a “Critical-High” water year type, providing for 70,919 acre-feet to be used for Restoration Program purposes.

In addition to the 2020 initial CVP water allocation, several South-of-Delta and Friant Division contractors are rescheduling unused water from 2019 supplies into 2020. That water is being stored in San Luis Reservoir and Millerton Lake. The option to reschedule (carry over) water in San Luis Reservoir and Millerton Lake from one contract year to the next has been available to the water service contractors since the early 1990’s. That carry over option was instituted after a series of dry years in the early 1990’s to encourage conservation and best water management practices.

Reclamation notified the Sacramento River Settlement Contractors, San Joaquin River Exchange Contractors, San Joaquin Settlement Contractors, and Refuge Contractors that the forecasted inflow to Shasta Lake is currently greater than 3.2 million acre-feet and we are not currently in a “Shasta Critical” year as that term is defined in their contracts.

As the water year progresses, changes in hydrology and opportunities to deliver additional water will influence future allocations. Water supply updates will be made as appropriate and posted at https://www.usbr.gov/mp/cvp-water/index.html.

SACRAMENTO, Calif. – The Bureau of Reclamation today announced the initial 2018 water supply allocation for many Central Valley Project contractors. This allocation is based on a conservative estimate of the amount of water that will be available for delivery to CVP water users and reflects current reservoir storages, precipitation and snowpack in the Central Valley and Sierra Nevada.

The 2017 water year was the wettest on record for most of northern California and CVP reservoirs were essentially full for the first time in five years; however, precipitation so far this year has been far below average. The California Department of Water Resources (DWR) reports that as of February 15, the statewide average snow water equivalent in the Sierra Nevada was 4.3 inches (20 percent of the historical average), and rainfall is currently at approximately 60 percent of the historical average for the northern Central Valley.

“Despite the historic rainfall last year, California’s lack of sufficient water storage forces us to operate on a year-to-year basis. The amount we can store in our reservoirs is not enough to get us through these very dry years,” said David Murillo, Reclamation’s Mid-Pacific Regional Director. “Given what we know today, and what we see in the forecast, we must be very conservative with our allocation. If this lack of rain and snow continues, we could very well be right back in drought operations. A situation like this really underscores the need for more storage in California.”

“There are many factors we have to consider when determining CVP allocations – hydrologic conditions, reservoir storage levels, water quality requirements, water rights priority, contractual obligations, and endangered species protections,” Murillo said. “All of these are taken into account with the goal of exercising all authorities available to us to maximize water supplies.”

Given storage of CVP water in San Luis, Millerton, and New Melones Reservoirs, as well as conservative assumptions regarding Delta operations over the next couple of months, Reclamation is able to provide an initial allocation to South-of-Delta, Friant, and Eastside contractors of the CVP. Regarding the remainder of the allocations to CVP contractors, although the CVP is operationally integrated, each individual reservoir has unique and specific operational criteria that must also be met. Due to the extremely low snowpack levels and associated runoff forecasts, combined with the uncertainty in the ability to manage Shasta Reservoir in a way that will provide adequate temperatures for the protection of endangered salmon species in the Sacramento River throughout the summer and fall in 2018, Reclamation will not be providing an initial allocation of water to North-of-Delta Contractors at this time. The integrated nature of the operation of Shasta and Folsom Reservoirs requires the same approach for American River and In-Delta Contractors.

Reclamation will be working with these contractors, as well as the National Marine Fisheries Service (NMFS), during the next week to ensure that water will continue to be delivered to meet public health and safety needs for Municipal and industrial (M&I) contractors and appropriate minimal needs of agricultural contractors during the month of March. This approach will allow Reclamation, NMFS, and the contractors to refine operating scenarios based on updated snowpack and runoff forecasts in March, and develop appropriate plans for dealing with the extremely dry conditions should they continue.

Should conditions change, CVP supplies could also change. Reclamation will continue working with the DWR, federal and state fishery agencies, our contractors, and others to effectively carry out project operations and improve water supply consistent with all applicable laws. Based on the information outlined above, Reclamation is announcing the initial allocation to the following:

South-of-Delta Contractors

  • Agricultural water service contractors South-of-Delta are allocated 20 percent of their contract total.
  • I water service contractors South-of-Delta are allocated the greater of 70 percent of their historic use or public health and safety needs.

Friant Division Contractors

  • Based upon Millerton Lake storage and current and forecasted hydrologic conditions in the Upper San Joaquin River Basin, the Friant Division contractors are allocated 30 percent of Class 1 supplies.
  • For the San Joaquin River Restoration Project, the current best forecast developed jointly by SJRRP and the South-Central California Area Office now indicates a “Critical-High” water year type.

Eastside Water Service Contractors

  • Eastside water service contractors (Central San Joaquin Water Conservation District and Stockton East Water District) will receive 100 percent of their contract total.

On February 15, Reclamation notified the Sacramento River Settlement Contractors, San Joaquin River Exchange Contractors, San Joaquin Settlement Contractors, and Refuge Contractors that the forecasted inflow to Shasta Lake is currently greater than 3.2 million acre-feet and we are not currently in a “Shasta Critical” year as that term is defined in their contracts.

Current dry conditions and the dry forecast underscore the need for all Californians to be conservative in their water use this spring, Murillo said. Without significant rain and snow this spring, conditions could worsen.

As the water year progresses, changes in hydrology and opportunities to deliver additional water will influence future allocations. Water supply updates will be made as appropriate and posted at http://www.usbr.gov/mp/cvp-water/index.html.

Reclamation Announces Initial Water Supply Allocation for the Central Valley Project

FEBRUARY 28, 2017

SACRAMENTO, Calif.  – The Bureau of Reclamation today announced the initial 2017 water supply allocation for Central Valley Project contractors in the Friant Division, Eastside Division and Municipal & Industrial Water Service Contractors in the American River Division.

“The 2017 water year has been an extreme year thus far, with precipitation throughout the Central Valley on track to be the highest in our historic records,” said Reclamation’s Acting Mid-Pacific Regional Director Pablo Arroyave. “As such, Reclamation is taking an approach to the announcement of CVP water allocations this year that differs from our historic practice.”

Given that inflow to Shasta Lake has already exceeded the volume necessary to be certain that this is not declared a Shasta Critical Year, Reclamation has notified the Sacramento River Settlement Contractors, San Joaquin River Exchange Contractors and Refuge Contractors of that fact. Regarding the remainder of the allocations to CVP contractors, although the CVP is operationally integrated, each individual reservoir has unique and specific operational criteria that must also be met. With this initial allocation announcement, Reclamation is targeting districts that receive water directly from Folsom, New Melones and Millerton reservoirs given the large snow pack and unusually high projected runoff this spring and summer.

The remaining water service contractors can expect an initial contract allocation amount in mid-to-late March. As Reclamation continues to refine the water supply allocation for these contractors, Reclamation will take advantage of the current hydrology to ensure specific districts’ water needs are met to the maximum extent practicable. While this allocation approach is warranted now, in future years Reclamation will continue to strive to release initial allocations for all water users in February.

Specific to the South-of-Delta water service contractors, a substantial amount of CVP water is already in storage south of the Delta, and the Federal share of San Luis Reservoir will be full within the first week of March. Given the extraordinary large snow pack and very high river flows this year, much of the water currently in storage in the Federal share of San Luis Reservoir will be available for delivery to CVP water service contractors this spring and summer.

Reclamation currently estimates that at least 900 thousand acre-feet of water will be available for delivery to South-of-Delta water service contractors this year, and additional supplies will likely be available once seasonal operational forecasts are developed later in March. The 900 taf estimate represents the combined delivery of both 2017 CVP supplies and carryover supplies from last year. The exact amount of each type of supply is subject to hydrologic conditions this spring, and the overall allocation of water south of the Delta must be validated by the operational studies to be based on the March 1 snow surveys and runoff forecasts.

The California Department of Water Resources reports that as of Feb. 27, 2017, the statewide average snow water equivalent in the Sierra Nevada was 45 inches, as compared to 21 inches on Feb. 27, 2016. Precipitation is currently over 200 percent of the seasonal average to date for the Sierra Nevada for this point in the water year (beginning Oct. 1, 2016).

Reclamation determines the allocation of water for CVP contractors based upon many factors, including hydrologic conditions, reservoir storage levels, water quality requirements, water rights, contractual obligations and endangered species protection measures. After evaluating these factors, Reclamation is announcing the initial allocation to the following:

American River Division Contractors

 American River Division M&I water service contractors will receive 100 percent of their contract supply.

Friant Division Contractors

 Pursuant to Reclamation’s previous discussions with Friant Division contractors and based upon Millerton Lake storage as well as current and forecasted hydrologic conditions in the Upper San Joaquin River Basin, the Friant Division allocation is 100 percent of Class 1 supplies. In addition, as long as current hydrologic and operational conditions exist and there is a need to evacuate water from Millerton Lake in order to prevent or minimize spill or to meet flood control criteria (currently referred to as “uncontrolled season”), Friant contractors may schedule and take delivery of Class 2 supplies up to the contract maximum, consistent with contract terms and conditions.

 Unreleased Restoration Flow supply related to the San Joaquin River Restoration Program of 358,730 acre-feet are being made available in a block that needs to be scheduled and delivered by June 15 to avert flood management concerns.

Eastside Water Service Contractors

 Eastside water service contractors (Central San Joaquin Water Conservation District and Stockton East Water District) will receive 100 percent of their contract supply.

This initial allocation is based on a conservative estimate of the amount of water that will be available for delivery to these CVP water users and reflects current reservoir storages, precipitation, and snowpack in the Central Valley and Sierra Nevada. “We will continue to carefully monitor hydrologic conditions and collaborate with our stakeholders and partners to manage our water resources as effectively as possible,” said Arroyave.

The CVP began the 2017 water year last October with 4.9 million acre-feet of carryover storage in six key CVP reservoirs — Shasta, Trinity, Folsom, Millerton, New Melones and the Federal share of San Luis Reservoir. This is 82 percent of the 15-year average annual carryover and 2 million acre-feet more than the amount with which the Mid-Pacific Region began WY 2016 on Oct. 1, 2015.

As the water year progresses, changes in hydrology and opportunities to deliver additional water will influence future allocations. Water supply updates will be made as appropriate and posted at http://www.usbr.gov/mp/cvp-water/index.html.

Reclamation Announces Initial Water Supply Allocation for the Central Valley Project

Media Contact: Shane Hunt, 916-978-5100

For Release: April 01, 2016

SACRAMENTO, Calif. – The Bureau of Reclamation today announced the initial 2016 water supply allocation for Central Valley Project (CVP) contractors. This allocation is based on a cautious estimate of the amount of water that will be available for delivery to CVP water users and reflects current reservoir storages, precipitation and snowpack in the Central Valley and Sierra Nevada.

The California Department of Water Resources (DWR) reports that as of March 30, 2016, the statewide average snow water equivalent in the Sierra Nevada is 24.4 inches, as compared to two inches on this date last year, and rainfall is currently at 125 percent of the historical average. However, in 2015 California experienced its fourth year of drought, and although conditions have greatly improved, Gov. Jerry Brown’s Emergency Drought Proclamation, issued January 17, 2014, remains in effect.

“While we are on track for near-average precipitation season this year, the ongoing and residual impacts of the multi-year drought continue. The impacts this summer will be greatest on the west side of the San Joaquin Valley and some areas served by New Melones Reservoir,” said Reclamation Mid-Pacific Regional Director David Murillo.

Reclamation determines the allocation of CVP water for agricultural, environmental, and municipal and industrial (M&I) purposes based upon many factors including hydrologic conditions, reservoir storage levels, water quality requirements, relative priority of water rights, contractual obligations, and endangered species protection measures.

This initial CVP allocation is also based on conservative assumptions regarding Delta operations over the next couple of months; however, should conditions improve, CVP supplies could also improve, with increased supplies to Reclamation contractors in the hard-hit San Joaquin Valley. Reclamation will continue working with the DWR, federal and state fishery agencies, our contractors, and others to effectively carry out project operations and improve water supply consistent with all applicable laws.

North-of-Delta Contractors

• Agricultural water service contractors North-of-Delta are allocated 100 percent of their contract supply.

• M&I water service contractors North-of-Delta are allocated 100 percent of their contract supply.

• Sacramento River Settlement Contractors are allocated 100 percent of their contract supply.

In-Delta

• The Contra Costa Water District, which receives water directly from the Delta, is allocated 100 percent of its contract supply.

South-of-Delta Contractors

• Agricultural water service contractors South-of-Delta are allocated 5 percent of their contract supply.

• M&I water service contractors South-of-Delta are allocated 55 percent of their historic use.

• San Joaquin River Exchange and Settlement Contractors are allocated 100 percent of their contract supply.

Wildlife Refuges

• Wildlife refuges (Level 2) North- and South-of-Delta are allocated 100 percent of their contract supply.

Friant Division Contractors

• Pursuant to Reclamation’s March 18 notification to Friant Division contractors and based upon Millerton Lake storage and current and forecasted hydrologic conditions in the Upper San Joaquin River Basin, the Friant Division allocation is 30 percent of Class 1 supplies.

• In addition, an Uncontrolled Season supply of 100,000 acre-feet and Unreleased Restoration Flow supply related to the San Joaquin River Restoration Program of 85,000 acre-feet are being made available as blocks that need to be scheduled and delivered by May 1 and May 15 respectively to avert flood management concerns.

Eastside Water Service Contractors

• Eastside water service contractors (Central San Joaquin Water Conservation District and Stockton East Water District) will receive 0 percent of their contract supply due to a lack of available CVP supplies from New Melones Reservoir.

In 2015, Reclamation undertook extraordinary actions to provide public health and safety supplies to our M&I contractors, meet our obligations to the San Joaquin River Exchange Contractors and South-of-Delta refuges, and facilitate water transfer and water sharing agreements throughout the Central Valley.

The CVP began the water year last October with only 47 percent of average storage overall and just 27 percent of average storage in the Federal share of San Luis Reservoir. This compares to 85 percent of average overall for the CVP and 53 percent of average storage in the Federal share of San Luis Reservoir today. Dry conditions in the fall of 2015 also hampered the filling of San Luis Reservoir. Further, throughout the fall and most of the winter, Reclamation held releases to minimal levels to conserve storage in upstream reservoirs.

The combined effect of four years of drought, lack of available water at the beginning of the 2016 water year, and restrictions to protect listed species are impacting the amount of water that can be allocated to South-of-Delta agricultural water service contractors. As the water year progresses, changes in hydrology and opportunities to deliver additional water will influence future allocations. Water supply updates will be made as appropriate and posted at http://www.usbr.gov/mp/cvp-water/index.html.

Bureau of Reclamation Outlines Water Year 2016 Central Valley Project Water Supply Conditions

Media Contact: Shane Hunt, 916-978-5100

For Release: January 22, 2016

RENO, NEV. – In preparation for the initial 2016 water supply allocation announcement later this winter, the Bureau of Reclamation is providing an update on water supply conditions for the federal Central Valley Project (CVP). The water year (WY) runs from October 1 to September 30; the contract year for most CVP contractors runs from March 1 to February 28.

The CVP’s reservoir carryover storage from WY 2015 into WY 2016 (October 1, 2015) was 2.9 million acre-feet, which was 24 percent of capacity and 47 percent of the 15-year average for that date in six key CVP reservoirs (Shasta, New Melones, Trinity, Folsom, Millerton, and the federal portion of San Luis). The table below shows conditions in those reservoirs as of January 22 for 2016, 2015, 2014 and 2013. As of January 19, 2016, storage in major CVP reservoirs was .963 million acre-feet lower than a year ago.

“On December 30, the California Department of Water Resources (DWR) held their first manual snow survey of the year and found the water content to be 16.3 inches, or 136 percent of the January 1 average. With this promising news and El Niño storms beginning to materialize, we are feeling encouraged,” said Mid-Pacific Regional Director David Murillo. “However, storage in our reservoirs remains low, and we must be prudent as we develop initial operation plans and allocations for CVP water contractors.”

As of January 19, DWR reported that the Northern Sierra 8-Station Precipitation Index Water Year total was 25.4 inches, which is about 109 percent of the seasonal average to date and 51 percent of an average water year (which is 50.0 inches). The San Joaquin 5-Station Precipitation Index Water Year total was 20.6 inches, which is 116 percent of the seasonal average to date and 50 percent of an average water year (which is 40.8 inches).

On January 15, 2016, Reclamation, DWR, the U.S. Fish & Wildlife Service, National Marine Fisheries Service, and California Department of Fish and Wildlife submitted the 2016 Drought Contingency Plan to the State Water Resources Control Board (SWRCB). The Plan outlines projected water operations and potential modifications to water quality rules and water rights permits that project operators may seek, depending on developing hydrologic conditions. The Plan is available on the SWRCB website athttp://www.waterboards.ca.gov/waterrights/water_issues/programs/drought/tucp/docs/febnov_2016plan.pdf .

As required by the exchange and settlement contracts, an initial declaration of whether 2016 is a Shasta Critical year will be announced on or before Feb. 15, 2016. Water supply updates will be made monthly or as appropriate and will be posted on Reclamation’s website at http://www.usbr.gov/mp/cvp-water.

Reclamation balances the operation of the CVP and delivery of CVP water for agricultural, municipal and industrial, and environmental purposes based on factors that include hydrology, changing river and Delta conditions, storage in CVP reservoirs, regulatory requirements, court decisions, biological opinions, environmental considerations, operational limitations and input from other agencies and organizations.
