State Water Project Table A contractors received a final allocation of 40 percent of contract supply for 2025, an above normal water year. Across 1996 to 2025 the class averaged 59 percent, from 5 percent in 2014, 2021, 2022 to 100 percent in 1997, 1998, 1999 and 3 other years.
How often did the class get its full supply?
In 6 of the 30 years the allocation reached 100 percent, and in 0 it was zero. CVP south-of-Delta agriculture averaged 42 percent over the same years, so the two classes moved apart; the allocation rules treat contract types differently by design, and exports at the Delta pumps serve both cities and farms.

How this supply measures against others
At 40 percent, the 2025 Table A allocation amounts to about 1.67 million acre-feet against the 4.17 million acre-foot maximum Table A amount held by the State Water Project's 29 contractors, which is 0.95 times California's 4.4 million acre-foot basic apportionment of the Colorado River under the Boulder Canyon Project Act of 1928.
Frequently asked questions
What was the SWP Table A allocation for 2025?
40 percent of contract supply, announced as the final figure for the year by the Department of Water Resources.
What is a typical SWP Table A allocation?
Over 1996 to 2025 the final allocation averaged 59 percent and reached 100 percent in 6 of 30 years.
Is an allocation the same as a delivery?
No. An allocation is the share of contract supply that the project tells its contractors to expect for the year. Delivered volumes are recorded separately by each project.
