March 2006 CVP Water Supply Information Announced
The Bureau of Reclamation today announced the March Water Year 2006
water supply allocation from the Federal Central Valley Project (CVP).
Reclamation prepared two forecasts. Water supplies projected in the
first forecast are associated with dry hydrological conditions that have
a 90-percent chance of exceeding the projection. Reclamation uses this
dry forecast for the official water supply allocation. The second
forecast is prepared for informational purposes using median
hydrological conditions that have a 50-percent chance of exceeding the
projection. This announcement of the available water supply allocation
is based on the March 1, 2006, runoff forecast prepared by the
California Department of Water Resources (DWR).
Water Year 2006 Water Allocation
North of Delta (percentages of contracted water allocated)
South of Delta (percentages of contracted water allocated)
104% of Avg
115% of Avg
Recent Historic Average (5-Year Average Allocation)
Ag = Agriculture M&I = Municipal and Industrial R = Refuges
WR = Water Rights
M&I Allocations are based on historical deliveries.
The Trinity River year type is projected to be in the "Wet" category in
both the dry and median forecasts. Wet-year releases will total 701,000
The Friant Division deliveries for Water Year 2006 are projected to be
1.5 million acre-feet, or 100 percent of the historic water supply of
1.5 million acre-feet. The preliminary allocation for Friant Division
contractors will be
100 percent Class 1 water and Uncontrolled Season for Class 2 water.
The Uncontrolled Season will be effective from March 1 through mid-June
2006. The projected Friant Division delivery of 1.5 million acre-feet
is based on DWR's 50-percent exceedence forecast. Through March 13,
2006, precipitation in the San Joaquin River watershed was
36.55 inches compared to 40.81 inches this time last year.
The CVP Cross Valley Canal Contractors' 65-percent water supply
allocation remains unchanged. This water supply is dependent upon
adequate capacity being available at the State Water Project Banks
Pumping Plant to convey the water.
In both the dry and median forecasts, the water supply available for the
CVP Eastside Division contractors (Stanislaus River) is projected to
remain at approximately 155,000 acre-feet.
Throughout the precipitation season, updated information will be
provided as conditions warrant. For additional information on the Water
Year 2006 water supply, please contact the Public Affairs Office at
TDD 916-978-5608. In the coming months, additional information will
continue to be posted on the Central Valley Operations website at
