AJR 38 (Caballero) - As Proposed to be Amended: May 11, 2010
SUBJECT : Sacramento-San Joaquin Delta: Two-Gates Project
SUMMARY : This resolution would request the United States
Department of the Interior (USDOI) to complete its study of the
Two-Gates Fish Protection Demonstration Project (Two-Gates
Project) in the Sacramento-San Joaquin Delta Estuary (Delta).
Specifically, this resolution :
1)Acknowledges that between 2007 and 2009 California experienced
a severe drought that adversely affected water supplies in
many parts of the state.
2)States that in 2009 State Water Project (SWP) and federal
Central Valley Project (CVP) water supply reductions were due
to drought, and to a lesser extent, made to protect state and
federally listed smelt, salmon, and steelhead.
3)Acknowledges that in 2009, while senior CVP water users south
of the Delta received 60-100% of contract amounts,
agricultural water users on the Westside of the San Joaquin
Valley received 10% of contract amounts.
4)States that in 2009 recession, drought, water supply
reductions and other hardships combined to affect farm
workers, ag-related jobs, and small businesses in the San
Joaquin Valley.
5)States that the Two-Gates Project is an experimental project
that proposes to install barriers and gates in the Delta to
reduce the loss of Delta smelt at the SWP/CVP pumps and infers
the Two-Gates Project would allow greater SWP/CVP export water
deliveries.
6)Underscores the importance of the Delta and the need to
identify and implement programs to advance California's
co-equal goals of protecting and restoring the Delta ecosystem
while ensuring a reliable water supply for California.
7)Calls on the USDOI to prioritize completion of the Two-Gates

Project study.
EXISTING LAW :
1)Prohibits the unauthorized take of species listed as
threatened and endangered under the federal Endangered Species
Act (ESA) and California Endangered Species Act (CESA).
2)Requires the SWP and CVP, which operate in a coordinated
fashion, to (at certain key times) restrict the degree to
which they cause Old River and Middle River in the Delta to
run backwards drawing aquatic organisms, including threatened
and endangered fish species, into the South Delta and the
SWP/CVP pumping plants.
FISCAL EFFECT : Nonfiscal
COMMENTS : The human suffering in the San Joaquin Valley due to
the economic downturn, subsequent loss of jobs in the
construction industries, drought, and related reductions in farm
employment, is tragic and well-documented. Whether water supply
reductions, either due to the drought or a combination of
drought and pumping restrictions, have played any major role is
less clear. Murkier still is whether the Two-Gates Project
would provide a feasible alternative to protections currently
needed to protect smelt, salmon and other imperiled species
while allowing increased water supply exports.
The Two-Gates Project would erect a sheet pile barrier over 800'
wide from levee to levee anchored in the bed of Old River with
two gates creating a 75' channel opening in the middle. The
Project would erect a second sheet pile barrier over 400' wide
from levee to levee anchored in the bed of Connection Slough
near Middle River with two gates creating a 60' opening in the
center. Each barrier would have a boat ramp to be used when the
gates are closed, which would occur periodically December
through June.
The scientific hypothesis behind the Two-Gates Project is that
Delta smelt respond to changes in salinity and turbidity and
that barriers across Old River and Connection Slough will
"manipulate water flows, transport patterns and the turbidity
field in the [Delta] so as to lessen entrainment of federally
(ESA threatened) and state (California CESA endangered)
protected juvenile and adult Delta smelt by state and federal
pumps in the south Delta" so as "to provide equal or improved

protection of Delta smelt" with higher water exports than
currently allowed under the Delta smelt biological opinion.
In December 2009, the USDOI sent letters to San Luis and Delta
Mendota Water Agency (SLDMWA) and Metropolitan Water District
(MWD), the sponsors of the Two-Gates Project, advising:
We have conducted a thorough review of all aspects of the
Demonstration Project and of the documentation that has
been provided. Based on our review, and in consideration
of several factors, we have concluded that the underlying
scientific premise of the project needs to be established
before the projects can go forward, including the
installation of the proposed gates?We also note that the
cost of the Demonstration Project has escalated from an
early estimate of $29 million to current estimates of
between $60 and $80 million. A decision to expend public
funds of this magnitude cannot prudently be made in light
of the fundamental questions that have been raised
regarding whether the scientific assumptions that underlie
the project are sound and, as a result, whether the project
will serve its intended purpose. That is why we have moved
quickly to work with the [United States Geological Survey]
to obtain needed data to evaluate interactions between
Delta smelt and turbid waters. Reclamation has redirected
funds on an emergency basis, thereby enabling this
data-gathering work to begin this fall.
Finally, while we recognize that expediting the permitting
process for the Demonstration Project has garnered strong
local, state, and Federal support, we have received over
1400 comment letters on the draft Environmental Assessment
for the project from concerned citizens and organizations
questioning the scientific basis, the benefits, and the
potential impacts of the proposed action. In addition, the
November 2009 Design, Estimating, and Construction Review
noted nine findings and recommendations that needed to be
addressed to ensure the technical soundness of the
Demonstration Project, and to provide a credible basis for
decision-making.
We are committed to working with SLDMWA, MWD, and the
scientific community to resolve the scientific, navigation,
and economic issues associated with the Demonstration
Project.

Supporters of this Resolution feel it is needed "to keep the
federal government's 'feet to the fire' to implement the
projects as soon as possible." Opponents of the project state
it is "an expensive scientific experiment with little chance of
success?that has serious impacts on the Delta and its
communities." In addition, Delta Counties and recreational
boating interests feel the project as designed does not
sufficiently address potential impacts on navigation including
the ability of law enforcement officials to conduct search and
rescue operations and enforce laws and regulations on the
waterways.
Finally, there are concerns by some members of the scientific
community that smelt and salmon are subject to increased
predation near artificial in-river structures and that the
project may adversely affect critical habitat.
