Lower Mokelumne River Restoration Program, Lower Mokelumne River,
California
AGENCY: Bureau of Reclamation, Interior.
ACTION: Notice of intent to prepare an environmental impact report/
environmental impact statement.
-----------------------------------------------------------------------
SUMMARY: Pursuant to the National Environmental Policy Act (NEPA) of
1969 (as amended) Reclamation (Reclamation) proposes to participate in
a joint Environmental Impact Report/Environmental Impact Statement
(EIR/EIS) for the Lower Mokelumne River Restoration Program. Woodbridge
Irrigation District (WID) will be the lead agency under the California
Environmental Quality Act (CEQA). The project is intended to provide
NEPA and CEQA clearance for implementing fish passage improvements at
Woodbridge Dam and fish screen improvements at Woodbridge Canal and the
North San Joaquin Water Conservation District diversion. Programmatic
clearance is being sought for the riparian restoration and riparian
diversion screening elements of the program. This work is being funded
through a Category III grant provided by the CALFED Bay-Delta Program
(CALFED) and administered by Reclamation.
DATES: Reclamation will seek public input on alternatives, concerns,
and issues to be addressed in the EIR/EIS through scoping meetings to
be held in January 1999. The schedule of the scoping meetings is as
follows:
Thursday, January 7, 1999, from 7 p.m. to 9 p.m. in Lodi,
California.
Wednesday, January 6, 1999, from 7 p.m. to 9 p.m. in
Sacramento, California.
If special services are needed at the meetings, contact Mr. Anders
Christensen at the address or telephone number listed below no later
than December 30, 1998.
Written comments on the scope of alternatives and impacts to be
considered should be sent to WID at the address below by [insert date
35 days after date of publication in the Federal Register]. Reclamation
estimates that the draft EIR/EIS will be available for public review in
summer 1999.
ADDRESSES: Meeting locations are: Lodi--Carnegie Forum at 305 West Pine
Street in Lodi, California Sacramento--Jones & Stokes Associates, Inc.,
Auditorium at 2600 V Street in Sacramento, California.
Written comments on the project scope should be sent to Anders
Christensen, Woodbridge Irrigation District, 18777 N. Lower Sacramento
Road, Woodbridge, CA 95258.

or Buford Holt of Reclamation at (530) 275-1554.
SUPPLEMENTARY INFORMATION: WID provides irrigation water for
approximately 40,000 acres of farmland near the city of Lodi. WID's
rights are based on riparian use before 1914 and other appropriative
rights. Flashboards are placed in the WID dam (Woodbridge Dam) in late
February or early March to begin filling Lodi Lake and to allow water
to flow into Woodbridge Canal for delivery to WID customers. The
flashboards are usually removed from the dam when the irrigation season
ends in early November.
The Lower Mokelumne River Restoration Program (LMRRP) was developed
to implement important elements from resource management plans prepared
by CALFED, the U.S. Fish and Wildlife Service (FWS), and the California
Department of Fish and Game (DFG). The goal of the LMRRP is to
substantially increase fall-run chinook salmon and steelhead
populations, enhance critical and limiting aquatic habitats, and
restore riparian ecosystem integrity and diversity. The LMRRP comprises
four major elements:
Element 1: Improve fish passage.
Element 2: Improve fish screening at Woodbridge and North
San Joaquin Water Conservation District diversions.
Element 3: Install or upgrade fish screens on riparian
diversions.
Element 4: Enhance riparian corridor.
WID and the city of Lodi applied for a CALFED Category III grant to
fund the LMRRP. CALFED has provided preliminary funding for final
design and for environmental clearance and permitting for Elements 1
and 2 of the LMRRP. WID and Reclamation will prepare the EIR/EIS using
this funding. Because final design for Elements 3 and 4 has not yet
been funded, it is anticipated that only programmatic environmental
clearance will be sought for these two elements.
Element 1: Improve fish passage
The LMRRP fish passage element seeks to improve upstream and
downstream fish passage on the Lower Mokelumne River and to provide the
opportunity to pass water of varying temperatures and pulse flows
downstream of WID's diversion while maintaining WID's access to its
water rights. Proposed alternative methods for implementing Element 1
are described below under ``Alternatives Being Considered.''
Element 2: Improve fish screening at Woodbridge Canal and North San
Joaquin Water Conservation District Diversions
Improving fish screening at Woodbridge Canal and North San Joaquin
Water Conservation District diversions would upgrade the fish screening
facilities at the two largest diversions on the Lower Mokelumne River
below Camanche Dam. New screens would be designed to meet all
applicable DFG and National Marine Fisheries Service (NMFS) criteria to
ensure effective fish passage and minimize entrainment and impingement.
Element 3: Install or Upgrade Fish Screens on Riparian Diversions
The riparian fish screening element would provide state-of-the-art
fish screens at 58 unscreened or underscreened riparian diversions on
the Lower Mokelumne River between Camanche Dam and its confluence with
the Cosumnes River near Thornton. All new screens would be designed to
meet all applicable DFG and NMFS criteria to ensure effective fish
passage and minimize entrainment and impingement.
Element 4: Enhance Riparian Corridor
The riparian corridor enhancement element includes bank erosion
control, riparian plantings, the creation of buffer zones, and other
techniques to restore and protect riparian vegetation to provide shaded
riverine aquatic habitat for fish, reduce water temperatures, increase
food production, and serve as a barrier between the river and adjacent
land uses.
Alternatives Being Considered
The project sponsors are considering alternatives to improve fish
passage while maintaining WID's access to its
[[Page 71950]]
water rights. A first-phase screening process was conducted to narrow a
list of 14 alternatives to a list of 5 feasible alternatives to be
analyzed in the EIR/EIS. These alternatives include:
1. No action. Under the No-Action Alternative, no physical changes
to the structure or functions of Woodbridge Dam or the Woodbridge fish
screen and bypass system would be made. The dam, fish screen, and
bypass system would continue to operate as they currently operate.
2. Build new fish passage facilities at Woodbridge Dam and replace
fish screen bypass at Woodbridge Canal. Under this alternative, the
problems with Woodbridge fish passage facilities would be corrected.
Because upgrading existing facilities to state-of-the-art
specifications is not feasible, new facilities would be built on the
right abutment (facing downstream) of the dam. Another element of this
alternative is the construction of a predator-isolation berm. This berm
would extend east to west across the channel that connects the river to
the oval, static portion of Lodi Lake. The berm would assist in
separating predator species in the static portion of Lodi Lake from
salmon and steelhead in the river.
3. Remove Woodbridge Dam and pump water into Woodbridge Canal.
Under this alternative, Woodbridge Dam would be removed and water to
serve WID customers would be obtained by pumping water from the
Mokelumne River into the Woodbridge Canal. A pump station with a state-
of-the-art fish screen would be constructed near the existing diversion
structure. Additionally, a river control structure would need to be
constructed to direct river flows toward the pumps and to keep the
pumps submerged.
4. Replace Woodbridge Dam with a new dam incorporating state-of-
the-art fish passage facilities (proposed project). The proposed
project involves removing the existing Woodbridge Dam and constructing
an adjustable weir dam immediately upstream. This dam would include new
state-of-the-art fish passage facilities, a downstream hydraulic
control system to manage tailwater elevations at the entrances to the
fish ladders, a gated system for the downstream release of water from
different strata for temperature control, and the capability of
providing releases across a wider spectrum of flow levels (0-800 cubic
feet per second [cfs]) without spillage across the dam face to improve
responsiveness to fish flow needs. It would also include the predator-
isolation berm described under Alternative 2.
5. Shorten period of flashboard placement in Woodbridge Dam and
install diversion pumps. This alternative is based on the assumption
that significant improvements to fish migration can be achieved by
removing the flashboards at Woodbridge Dam from March through June to
improve downstream migration of juvenile salmon and steelhead. To
accommodate WID's need to divert water during that period, diversion
pumps would be installed and a river control structure would be
constructed to direct river flows toward the pumps and to keep the
pumps submerged. This alternative would also include the predator-
isolation berm described under Alternative 2.
The project sponsors are also considering the following option
which could be implemented with any of the alternatives that include a
dam.
Construct a stratification sill in front of the WID diversion
structure and a new deepwater discharge outlet in the dam. This option
is based on the assumption that a shortage of cool water below
Woodbridge Dam is a limiting factor for salmon during their smolt out-
migration life stage and that such cool water is available in Lodi
Lake. The intent is to provide warm water for the Woodbridge Canal and
to allow cool water to flow downstream of Woodbridge Dam. The cool
water would also be used to guide fish away from the diversion to the
bypass canal that would lead them to the river below the dam.
Scoping Process
Scoping is an early and open process designed to determine the
significant issues and alternatives to be addressed in the EIR/EIS.
Following are significant issues that have been identified: fisheries,
riparian and wetland habitats, wildlife, water quality, aesthetics,
recreation, and public health and safety.
Special Services
If special services are required at the meeting, contact Anders
Christensen. Please notify Mr. Christensen as far in advance of the
meetings as possible but no later than December 30, 1998, to enable WID
to secure the needed services. If a request cannot be honored, the
requestor will be notified. A telephone device for the hearing impaired
(TDD) is not available.
