k. The project consists of two
developments: Warne Development and
Castaic Development. The average
annual generation of the South SWP
Project from 2007 to 2017 was 304
gigawatt-hours (GWh) at the Warne
powerplant and 379 GWh at the Castaic
powerplant.
Jkt 250001
The major features of the Warne
Development include: (1) Quail Lake,
(2) Lower Quail Canal, (3) Peace Valley
pipeline intake embankment, (4) Peace
Valley pipeline, (5) Gorman bypass
channel, (6) the William E. Warne
powerplant (Warne powerplant), (7)
switchyard, (8) the transmission line
that interconnects Warne powerplant
with the Southern California Edison
(SCE) Pastoria-Pardee transmission line,
and (9) appurtenant facilities.
Quail Lake is a small regulating
reservoir along the State Water Project
(SWP) that was created by constructing
an embankment along a sag pond
formed by the San Andreas fault. The
lake is located 5 miles southwest of the
bifurcation of the East and West
branches of the SWP. Quail Lake has a
maximum storage capacity of 8,790
acre-feet and a surface area of about 290
acres. The Quail Lake outlet into Lower
Quail canal is a double-box culvert
structure that passes beneath State
Highway 138. Quail Lake and Lower
Quail canal serve as a forebay to Warne
powerplant. The Lower Quail canal has
an emergency outflow weir that is
described below, and a spillway is not
required for Quail Lake.
Water released from Quail Lake
through the Quail Lake outlet flows into
the 2-mile-long Lower Quail canal. The
concrete-lined canal serves as a
conveyance to the Peace Valley pipeline
intake and is the forebay for the Warne
powerplant. Lower Quail canal has a
bottom width of 24 feet, northern
embankment height of approximately 50
feet, southern embankment height of
about 40 feet, and maximum flow
capacity of 3,129 cubic feet per second
(cfs). The Lower Quail canal storage
capacity is 1,150 acre-feet. An ungated
emergency overflow weir is located on
the north side of Lower Quail canal. If
an unplanned release occurs, water can
be discharged over the ungated weir
into a detention basin located to the
PO 00000

west and adjacent to the southernmost
section of Lower Quail Canal.
The Peace Valley pipeline begins at
the Peace Valley pipeline intake
embankment. The Peace Valley pipeline
intake embankment is a zoned earth and
rockfill embankment at the downstream
end of the Lower Quail canal. The Peace
Valley pipeline intake embankment is
50 feet tall, with a crest length of 350
feet, and crest elevation of 3,330 feet.
SWP water flowing from Quail Lake
through Lower Quail canal is routed
into the Peace Valley pipeline to Warne
powerplant and then to Pyramid Lake.
The Peace Valley pipeline, which has a
12-foot-diameter and is completely
underground, serves as the penstock to
the Warne powerplant. It extends about
5.5 miles from the Peace Valley pipeline
intake structure to the Warne
powerplant. In the event of a Peace
Valley pipeline outage or scheduled
SWP water releases exceeding the
pipeline’s capacity, the water is routed
through the Gorman bypass channel
directly into Pyramid Lake.
The Gorman bypass channel flow
capacity is 700 cfs and conveys SWP
water from Lower Quail canal to
Pyramid Lake, bypassing the Peace
Valley pipeline and Warne powerplant,
when necessary, with an alignment
generally paralleling that of the Peace
Valley pipeline. The man-made channel
begins at the Peace Valley pipeline
intake embankment and crosses
Interstate 5 about 0.7 mile downstream
from the embankment. Local drainage, if
any, drains into the bypass channel near
Interstate 5.
The Warne powerplant, an aboveground, steel-reinforced, concrete
powerhouse, is located at the northern
(upstream) end of Pyramid Lake, at the
terminus of the Peace Valley pipeline.
The powerplant has two 37.5–MW
Pelton-type generating units. Each
turbine has a rated head of 650 feet,
runner speed of 200 revolutions per
minute (rpm), rated output of 51,000
horsepower (hp), and a rated discharge
of 782 cfs. The total combined flow
capacity for the powerplant is 1,564 cfs.
The project includes a 3-mile-long,
single-circuit, 220-kilovolt (kV)
transmission line that connects output
from the project through the Warne
switchyard to SCE’s Pardee-Pastoria
transmission line. The line is built on
steel lattice towers along a 150-footwide right-of-way. The Warne
switchyard is located west and
immediately adjacent to the Warne
powerplant and contains two generator
step-up transformers.

Castaic Development
The major features of the Castaic
Development include: (1) Pyramid dam,
(2) Pyramid Lake, (3) the Angeles tunnel
and seven penstocks, (4) the Castaic
powerplant and switchyard, (5) the
Elderberry forebay and dam, (6) storm
bypass channel and check dams, (7) the
transmission lines that interconnect
Castaic switchyard with the
Independent System Operator power
grid, and (8) appurtenant facilities. DWR
owns and operates the facilities above
the surge chamber at the southeastern
end of the Angeles tunnel, and LADWP
owns and operates the remainder of the
facilities, including the surge chamber.
Pyramid dam, at the southern end of
Pyramid Lake, is a 1,090-foot-long, 400foot-high zoned earth and rock fill dam.
The crest of the dam is 35 feet wide
with an elevation of 2,606 feet. Water is
typically released from a low-level
outlet to an 18-mile-long section of Piru
Creek (Pyramid reach), which extends
from Pyramid dam to the NMWSE of
Lake Piru.
Pyramid dam has two spillways, a
gate-controlled spillway, and an
uncontrolled emergency spillway. The
gated spillway is controlled by a single
radial gate that measures 40 feet wide by
31 feet tall and consists of a concretelined chute terminating in a flip bucket.
The low-level outlet works use the
stream bypass tunnel (diversion tunnel)
used during construction of the dam.
This stream release facility is a 15-footdiameter, concrete-lined tunnel about
1,350 feet long through the right
abutment of the dam and is used for
downstream releases to Pyramid reach.
Seepage through the dam is also
collected at the toe of the dam, where
it is gaged before being released into
Pyramid reach. The maximum safe,
designed release from the low-level
outlet of Pyramid dam to Pyramid reach
is 18,000 cfs.
Pyramid Lake serves as regulated
storage for the Castaic powerplant. At a
NMWSE of 2,578 feet, Pyramid Lake has
a storage capacity of 169,902 acre-feet
and a usable storage capacity of 22,221
acre-feet. Pyramid Lake also serves as
emergency storage for the SWP. The
lake has a normal maximum surface
area of approximately 1,300 acres, a
shoreline length of approximately 21
miles, and a maximum depth of
approximately 280 feet. Pyramid Lake
receives natural inflow into the west
arm of the lake from Piru Creek, and a
combination of natural and SWP water
inflows into the north arm of the lake
from Gorman bypass channel and
Gorman Creek.

Angeles tunnel, the principal outlet
from Pyramid Lake, supplies water to
the Castaic powerplant in the generating
mode and returns water to the lake from
Elderberry forebay when the powerplant
is operating in the pumping mode.
Angeles tunnel is 7.2 miles long, has a
diameter of 30 feet, and has a maximum
flow capacity of 18,400 cfs.
The penstock assembly for the six
units in the Castaic powerplant consists
of a double trifurcation immediately
downstream of the south portal of
Angeles tunnel, a penstock shutoff valve
on each branch of the trifurcations, and
six 2,200-foot-long steel penstocks
ranging in diameter from 9 feet to 13.5
feet serving the six powerhouse units
(Unit Nos. 1–6). Unit No. 7 powerplant
is served by a 1,900-foot-long steel
penstock ranging in diameter from 7 feet
to 9 feet branching from a Y-connection
between the tunnel portal and the main
trifurcation. Combined flow capacity for
all seven penstocks is 17,840 cfs.
The Castaic powerplant, an
aboveground/underground, steelreinforced, concrete powerhouse, is
located on the northern (upstream) end
of Elderberry forebay and is a pumpgenerating plant with the ability to
pump water back to Pyramid Lake using
off-peak energy when it is economical to
do so. Elderberry forebay serves as an
afterbay for the Castaic powerplant
while in generating mode and as a
forebay while in pumping mode.
Pyramid Lake serves as the upper
reservoir for the powerplant.
The powerplant has six Francis-type
pump-turbine units each with a rated
head of 1,048 feet, a runner speed of 257
rpm, a rated output of 355,000 hp, and
an estimated rated discharge of 3,500
cfs. It also has one Pelton-type pump
starting turbine unit with a rated head
of 950 feet, a runner speed of 225 rpm,
rated output of 69,000 hp, and an
approximate rated discharge of 752 cfs.
These seven units have a combined
generating capacity of 1,275 MW with a
plant hydraulic capacity of 17,840 cfs.
Elderberry forebay dam is a 1,990foot-long, 200-foot-high zoned earthfill
dam. The crest of the dam is 25 feet
wide with an elevation of 1,550 feet.
The outlet tower, located approximately
400 feet upstream of Elderberry forebay
dam, includes: One 5-foot-wide by 6foot-high main gate, six 8-foot-wide by
12-foot-high lower gates, two 8-footwide by 9-foot-high upper gates, twelve
13-foot-wide by 12-foot-high storm
gates, and one 5-foot-wide by 6-foothigh guard gate. The outlet tower
connects to a 21-foot-diameter conduit
that runs under Elderberry forebay dam
and releases water into Castaic Lake (a
non-project facility).

An overflow weir built into a natural
topographic saddle located
approximately 300 feet east of the left
abutment of the dam serves as an
uncontrolled emergency spillway. The
crest elevation of the overflow weir is
1,540 feet, with a capacity of at least
12,000 cfs. Elderberry forebay dam,
including this emergency spillway, is
the most downstream project facility.
Elderberry forebay serves as an
afterbay for the Castaic powerplant
when the plant is generating power, and
as a forebay when the plant is pumping
water back to Pyramid Lake. The
forebay also receives a small amount of
local inflow from Castaic Creek, which
enters at the northern end of the
reservoir. The remaining inflow to
Elderberry forebay is SWP water from
Pyramid Lake conveyed via the Angeles
tunnel. At a NMWSE of 1,530 feet,
Elderberry forebay has a storage
capacity of 28,231 acre-feet, a surface
area of 500 acres, and a shoreline length
of 7 miles.
The Storm bypass channel is on
Castaic Creek above Elderberry forebay
and includes a series of three check-dam
basins with a total area of approximately
21 acres, designed to capture sediment
runoff during high flow events to reduce
the accumulation of sediment near the
powerplant and ensure the sustained
efficiency of the Castaic powerplant
operation.
The Castaic switchyard is a fenced
switchyard located adjacent to the
powerhouse. An 11.4-mile-long, 230-kV
transmission line delivers energy from
the Castaic switchyard to the Haskell
Junction substation and transmits
energy to the Castaic powerplant when
in the pump-back operating mode.
Co-Licensees’ Proposed Modifications
In their Final License Application, the
co-licensees propose to add the
following facilities to the project
license: The existing Quail Detention
Embankment, segments of some existing
roads necessary for project operation
and maintenance, and an existing
streamflow gage located on Piru Creek
downstream of Pyramid Dam.
Additionally, the co-licensees propose
to remove the Warne Transmission Line
from the project license.
The co-licensees also propose to
modify the project boundary to reduce
the amount of land from 6,928 acres to
4,563.8 acres. The project, as proposed
by the licensee, would reduce the
amount of federal land from 2,790 acres
to 2,007 acres of federal lands: 1,336
acres administered by the U.S.

k. The project consists of two developments: Warne Development and
Castaic Development. The average annual generation of the South SWP
Project from 2007 to 2017 was 304 gigawatt-hours (GWh) at the Warne
powerplant and 379 GWh at the Castaic powerplant.
Warne Development
The major features of the Warne Development include: (1) Quail
Lake, (2) Lower Quail Canal, (3) Peace Valley pipeline intake
embankment, (4) Peace Valley pipeline, (5) Gorman bypass channel, (6)
the William E. Warne powerplant (Warne powerplant), (7) switchyard, (8)
the transmission line that interconnects Warne powerplant with the
Southern California Edison (SCE) Pastoria-Pardee transmission line, and
(9) appurtenant facilities.
Quail Lake is a small regulating reservoir along the State Water

embankment height of about 40 feet, and maximum flow capacity of 3,129
cubic feet per second (cfs). The Lower Quail canal storage capacity is
1,150 acre-feet. An ungated emergency overflow weir is located on the
north side of Lower Quail canal. If an unplanned release occurs, water
can be discharged over the ungated weir into a detention basin located
to the west and adjacent to the southernmost section of Lower Quail
Canal.
The Peace Valley pipeline begins at the Peace Valley pipeline
intake embankment. The Peace Valley pipeline intake embankment is a
zoned earth and rockfill embankment at the downstream end of the Lower

powerhouse, is located at the northern (upstream) end of Pyramid Lake,
at the terminus of the Peace Valley pipeline. The powerplant has two
37.5-MW Pelton-type generating units. Each turbine has a rated head of
650 feet, runner speed of 200 revolutions per minute (rpm), rated
output of 51,000 horsepower (hp), and a rated discharge of 782 cfs. The
total combined flow capacity for the powerplant is 1,564 cfs.
The project includes a 3-mile-long, single-circuit, 220-kilovolt
(kV) transmission line that connects output from the project through
the Warne switchyard to SCE's Pardee-Pastoria transmission line. The
line is built on steel lattice towers along a 150-foot-wide right-of-
way. The Warne switchyard is located west and immediately adjacent to
the Warne powerplant and contains two generator step-up transformers.

Castaic Development
The major features of the Castaic Development include: (1) Pyramid
dam, (2) Pyramid Lake, (3) the Angeles tunnel and seven penstocks, (4)
the Castaic powerplant and switchyard, (5) the Elderberry forebay and
dam, (6) storm bypass channel and check dams, (7) the transmission
lines that interconnect Castaic switchyard with the Independent System
Operator power grid, and (8) appurtenant facilities. DWR owns and
operates the facilities above the surge chamber at the southeastern end
of the Angeles tunnel, and LADWP owns and operates the remainder of the
facilities, including the surge chamber.
Pyramid dam, at the southern end of Pyramid Lake, is a 1,090-foot-
long, 400-foot-high zoned earth and rock fill dam. The crest of the dam
is 35 feet wide with an elevation of 2,606 feet. Water is typically
released from a low-level outlet to an 18-mile-long section of Piru
Creek (Pyramid reach), which extends from Pyramid dam to the NMWSE of
Lake Piru.
Pyramid dam has two spillways, a gate-controlled spillway, and an
uncontrolled emergency spillway. The gated spillway is controlled by a
single radial gate that measures 40 feet wide by 31 feet tall and
consists of a concrete-lined chute terminating in a flip bucket. The
low-level outlet works use the stream bypass tunnel (diversion tunnel)
used during construction of the dam. This stream release facility is a
15-foot-diameter, concrete-lined tunnel about 1,350 feet long through
the right abutment of the dam and is used for downstream releases to
Pyramid reach. Seepage through the dam is also collected at the toe of
the dam, where it is gaged before being released into Pyramid reach.
The maximum safe, designed release from the low-level outlet of Pyramid
dam to Pyramid reach is 18,000 cfs.
Pyramid Lake serves as regulated storage for the Castaic
powerplant. At a NMWSE of 2,578 feet, Pyramid Lake has a storage
capacity of 169,902 acre-feet and a usable storage capacity of 22,221
acre-feet. Pyramid Lake also serves as emergency storage for the SWP.
The lake has a normal maximum surface area of approximately 1,300
acres, a shoreline length of approximately 21 miles, and a maximum
depth of approximately 280 feet. Pyramid Lake receives natural inflow
into the west arm of the lake from Piru Creek, and a combination of
natural and SWP water inflows into the north arm of the lake from
Gorman bypass channel and Gorman Creek.
Angeles tunnel, the principal outlet from Pyramid Lake, supplies
water to the Castaic powerplant in the generating mode and returns
water to the lake from Elderberry forebay when the powerplant is
operating in the pumping mode. Angeles tunnel is 7.2 miles long, has a
diameter of 30 feet, and has a maximum flow capacity of 18,400 cfs.
The penstock assembly for the six units in the Castaic powerplant
consists of a double trifurcation immediately downstream of the south
portal of Angeles tunnel, a penstock shutoff valve on each branch of
the trifurcations, and six 2,200-foot-long steel penstocks ranging in
diameter from 9 feet to 13.5 feet serving the six powerhouse units
(Unit Nos. 1-6). Unit No. 7 powerplant is served by a 1,900-foot-long
steel penstock ranging in diameter from 7 feet to 9 feet branching from
a Y-connection between the tunnel portal and the main trifurcation.
Combined flow capacity for all seven penstocks is 17,840 cfs.
The Castaic powerplant, an aboveground/underground, steel-
reinforced, concrete powerhouse, is located on the northern (upstream)
end of Elderberry forebay and is a pump-generating plant with the
ability to pump water back to Pyramid Lake using off-peak energy when
it is economical to do so. Elderberry forebay serves as an afterbay for
the Castaic powerplant while in generating mode and as a forebay while
in pumping mode. Pyramid Lake serves as the upper reservoir for the
powerplant.
The powerplant has six Francis-type pump-turbine units each with a
rated head of 1,048 feet, a runner speed of 257 rpm, a rated output of
355,000 hp, and an estimated rated discharge of 3,500 cfs. It also has
one Pelton-type pump starting turbine unit with a rated head of 950
feet, a runner speed of 225 rpm, rated output of 69,000 hp, and an
approximate rated discharge of 752 cfs. These seven units have a
combined generating capacity of 1,275 MW with a plant hydraulic
capacity of 17,840 cfs.
Elderberry forebay dam is a 1,990-foot-long, 200-foot-high zoned
earthfill dam. The crest of the dam is 25 feet wide with an elevation
of 1,550 feet. The outlet tower, located approximately 400 feet
upstream of Elderberry forebay dam, includes: One 5-foot-wide by 6-
foot-high main gate, six 8-foot-wide by 12-foot-high lower gates, two
8-foot-wide by 9-foot-high upper gates, twelve 13-foot-wide by 12-foot-
high storm gates, and one 5-foot-wide by 6-foot-high guard gate. The
outlet tower connects to a 21-foot-diameter conduit that runs under
Elderberry forebay dam and releases water into Castaic Lake (a non-
project facility).
An overflow weir built into a natural topographic saddle located
approximately 300 feet east of the left abutment of the dam serves as
an uncontrolled emergency spillway. The crest elevation of the overflow
weir is 1,540 feet, with a capacity of at least 12,000 cfs. Elderberry
forebay dam, including this emergency spillway, is the most downstream
project facility.
Elderberry forebay serves as an afterbay for the Castaic powerplant
when the plant is generating power, and as a forebay when the plant is
pumping water back to Pyramid Lake. The forebay also receives a small
amount of local inflow from Castaic Creek, which enters at the northern
end of the reservoir. The remaining inflow to Elderberry forebay is SWP
water from Pyramid Lake conveyed via the Angeles tunnel. At a NMWSE of
1,530 feet, Elderberry forebay has a storage capacity of 28,231 acre-
feet, a surface area of 500 acres, and a shoreline length of 7 miles.
The Storm bypass channel is on Castaic Creek above Elderberry
forebay and includes a series of three check-dam basins with a total
area of approximately 21 acres, designed to capture sediment runoff
during high flow events to reduce the accumulation of sediment near the
powerplant and ensure the sustained efficiency of the Castaic
powerplant operation.
The Castaic switchyard is a fenced switchyard located adjacent to
the powerhouse. An 11.4-mile-long, 230-kV transmission line delivers
energy from the Castaic switchyard to the Haskell Junction substation
and transmits energy to the Castaic powerplant when in the pump-back
operating mode.
