a The values shown under "Existing Supplies" and "Planned Supplies" are supplies projected to be available in average/normal years.
The values shown under "Existing Banking Programs" and "Planned Banking Programs" are either total amounts currently in
storage, or the maximum capacity of program withdrawals.
b SWP supplies are calculated by multiplying CLWA's Table A Amount of 95,200 af by percentages of average deliveries projected to
be available, based on Tables 6-5 and 6-14 of DWR's " State Water Project Delivery Reliability Report 2007". Year 2030 figure is
calculated by multiplying by DWR’s 2027 percentage of 66%.
c Supplies shown are total amounts that can be withdrawn, and would typically be used only during dry years.
d Initial term of the Ventura County entities' flexible storage account is ten years (from 2006 to 2015).
e Supplies shown are the total amount currently in storage, and would typically be used only during dry years. Once the current
storage amount is withdrawn, this supply would no longer be available and in any event, is not available after 2013.
f CLWA has 64,900 af of recoverable water as of 12/31/07 in the Rosedale-Rio Bravo Water Banking and Recovery Program.
g Supplies shown are the total amount currently in storage. As of December 31, 2007, there is 18,828 af of water stored in the
Semitropic Groundwater Storage Bank by The Newhall Land and Farming Company for the Newhall Ranch Specific Plan. The
stored water can be extracted from the bank in dry years in amounts up to 4,950 afy. Newhall Ranch is located within the CLWA
service area.
h Recycled water supplies based on projections provided in CLWA's 2005 UWMP Chapter 4, Recycled Water.
