obligation set forth in the 2003 Monterey Settlement
 Reliability Report provides:
 Overall water delivery capacity of the SWP facilities
 Allocation of SWP water
 Discussion of the range of hydrologic conditions
 Historic SWP water delivery (prior 10 years)

Note: Maximum Annual SWP Exports from the Delta is 4,133 MAF
Approximately 79% chance
of annual Delta exports of

acre-feet under existing
conditions, reduced to
approximately 76% under
future conditions

9. The report illustrates “The need for local agencies to
develop a resilient and robust water supply, and a
distribution and management system to maximize the
efficient use of our variable supply” and “the urgent need
to improve the method of conveying water past the Delta
in a more sustainable manner that meets the dual goals
of increasing water delivery reliability and improving
conditions for endangered and threatened fish species.”
-- DWR Director Mark Cowin

10.  Future SWP deliveries average about 61% of the
contracted amount (including Article 21 and
carryover supplies)
 MWD’s 2010 UWMP and the Table A 2030 volumes
are consistent with the 2011 Report results for 2031.
 DWR will continue to perform assessments of SWP
supplies and operations
 Next SWP Delivery Report will be released in 2014
 Water Agencies to prepare 2015 Urban Water Management Plan
Updates
 Staff will continue to monitor and report to the Board
actions that could affect imported water
