Re: CVPIA Workplan 2012
Gentlemen:
The undersigned entities have concerns with the Central Valley Improvement Act
(CVPIA) work plan for 2012 with respect to efforts to improve salmon abundance in
the Central Valley. We assert the federal and state fishery agencies programs to
improve the abundance of salmon in the Central Valley need to be reevaluated and
radically revised.

We have read with interest the March 22 letter from the Golden Gate Salmon
Association (GGSA) on the CVPIA workplan and we generally agree with its
criticisms. Specifically, we support the conclusions in the first full paragraph on
page 2 of the GGSA letter that states in partthe 2012 (CVPIA) Restoration work
plans that have been prepared by USFWS and USBR are not really plans. They aresimply a collection of hundreds of projects that have been proposed by field offices
of the two agencies. Many of these projects are well conceived by capable and
dedicated staffs and will provide some benefits to salmon at some point. What is
missing is management oversight to see that the plans that are proposed and
accepted are focused on the reasons the salmon runs have declined and are focused
on the best investments to begin the early rebuilding process. They go on to state:
Many of the projects take place in the tributaries but there is no analysis made of
whether or not additional enhancements in a tributary will in fact produce
additional smolts to the ocean at an early date and adults to return three years later.
On the San Joaquin side, smolt losses in the South Delta are near 100%. Hundreds of
thousands of additional smolts would have to be produced in the tributaries to have
any true net impact on an increase in San Joaquin populations. The plan ignores this
kind of analysis in its San Joaquin expenditures. The same kinds of problems exist
on the Sacramento side. In some instances, up to 90% of the smolts perish on their
way down the river.
How can the CVPIA or the aggressive San Joaquin River Restoration Program
possibly improve salmon abundance and thus succeed if survival in the lower San
Joaquin River and in the South Delta is nearly zero? As summarized by the SWRCB
in their March 2012 science review of the San Joaquin River (see page 3- 39) this
drop in survival is a recent event. They noted that Independent Science Review of
the Vernalis Adaptive Management Program (VAMP) data found thatsurvival
estimates from Mossdale or Dos Reis to Jersey Point were just greater than 1% in
2003 and 2004 and the estimate was only about 12% in the very high flow year of
2006. This compares to survival estimates that ranged between about 30% and
80% in the years 1995 and 1997 to 2000. The likely cause for this decrease in
survival is the marked increase in aquatic weeds that provide better habitat for
invasive predatory fish like largemouth bass and black bass. These predatory fish
feed on young salmon and they are now so numerous that catch and release
tournaments are held regularly. The recent study entitled Individual-level and
Population-level Historical Prey on Demand of San Francisco Estuary Striped Bass
Using a Bioenergetics Model seems to support the notion that some of the non-native predators are an extensive source of mortality and yet, the fish agencies are
not taking any action to rectify this problem.
A much more holistic approach to salmon protection, which includes all life stages
and includes ocean conditions and harvest, is needed than that currently provided
by the state and federal fishery agencies. Considerable work has been conducted in
upstream areas to enhance fish passage, including the construction of state of the art
fish screens. Without a holistic approach, these efforts could be squandered by
predation in the Bay-Delta or other stressors that adversely affect fish during their

various life-cycles. We have independently reviewed the salmon programs of each of
the three fishery agencies and have come to the same conclusions of the GGSA. In
addition to no single comprehensive strategic approach to salmon restoration, there
are no integrated performance measures to gauge success or failure of actions. A
comprehensive overhaul of these programs is needed.
Of the three plans we reviewed, the NMFS plan is the most thoughtful from a science
perspective. The NMFS plan attempts to lay out processes to recover listed
anadromous salmonids by following a science-based approach that examines the
reasons behind current problems limiting recovery, then proposing actions to
address those problems. The lack of sufficient coordination among the three
resource agencies is a key factor that is visibly apparent when examining all the
inconsistencies among plans, including the general lack of agreement among
agencies as to what actions should be implemented and by whom.
NMFS, under advisement of the Pacific Fishery Management Council (PFMC),
currently regulates ocean fishing of Central Valley fall-run Chinook (CVF) based
solely on the Sacramento River population. The existing conservation objective for
CVF was developed before the CVPIA. Unfortunately, the conservation objective has
not been revisited since passage of the CVPIA and, as a result, was not developed
with consideration of the doubling goal. Ocean harvest regulations developed since
the passage of the CVPIA have similarly failed to incorporate the doubling goal. As a
result, NMFS has not evaluated whether current fishery management practices
impede doubling natural production. Current rates of ocean harvest are
unsustainable without hatchery augmentation and modernization of hatchery
practices, yet neither NMFS nor the PFMC distinguish between hatchery and natural
CVF.
We support the GGSAs call for a review and overhaul of the CVPIA salmon program
but believe it needs to go beyond CVPIA and integrate with all the activities of the
state and federal fishery agencies related to salmon. While many of these programs
focus on natural production, specific actions are needed to make the salmonid
hatchery programs more efficient in producing fish for harvest in the ocean while
minimizing impacts to natural populations, to reduce straying, and to minimize
harvest take of listed species. Hatchery production is over half of the ocean catch off
Californias coast. Also, hatchery produced fish on average make up over half the
natural area escapement in the Central Valley and ranges from 22% to 96% of thetotal number of salmon returning to spawn (as documented in the March 2012
report on results from the constant fractional marking program by the Department
of Fish and Game). It is time to define the role of hatcheries in overall salmon
management and implement programs to enhance natural production while
retaining the benefits of improved ocean abundance provided by hatcheries.
A new restoration strategy should be science-based, pragmatic, and candid about
realistic goals and the opportunities for anadromous salmonid restoration in
recognition of the importance of salmon hatcheries. The plan should be routinely

revised to reflect new information, accomplishments, and failures. If the
recommended approach is not taken, it would appear that the resource agencies will
continue to repeat the same debates into the future leaving the anadromous
salmonid resource at risk.
We intend these comments to be constructive and are truly committed to help make
these programs more effective in the future. We look forward to working with you,
the GGSA, and others in your ongoing efforts to improve the abundance of salmon in
the Central Valley.
Sincerely yours,
