How
to Prepare a Water Availability Analysis
- Before
preparing a WAA, you may want to
contact a consultant.
- You may use this formatted Example of a WAA Memorandum as a guide for your WAA. (Word format.) Alternatively, you may propose any other methodology that can be supported by the unique circumstances of your situation.

A
Water Availability Analysis is required by the
California Water Code. Pertinent provisions of the
Water Code are summarized below:
- every
water right application submitted to the SWRCB must
include "sufficient information to demonstrate
a reasonable likelihood that unappropriated water
is available for appropriation." (Water Code
section 1260(k))
- "in
determining the amount of water availability for
appropriation, the SWRCB shall take into account,
whenever it is in the public interest, the amounts
of water needed to remain in the source for protection
of beneficial uses..." Instream beneficial
uses include, but are not limited to, recreation
and the preservation of fish and wildlife habitat.
(Water Code section 1243)
- before
the SWRCB can grant a water right permit, it must
find that there is "unappropriated water available
to supply the applicant." (Water Code section
1375(d))
As
a follow up to the June 2001 MBK study, the U.S. Geological
Survey is evaluating SWRCB's Flow Estimation methods
in the North Coast Region. Study results will be
published in an Open File Report scheduled for completion
in July 2003.
In
June 2001, MBK Engineers completed an evaluation of
the SWRCB's Water Availability Analysis.
