RE: DeSabla-Centerville Hydroelectric Project, FERC No. 803-CA
Revised Public Safety Plan
Dear Frank L. Blackett:
This letter presents Pacific Gas and Electric Company’s (PG&E) re-submission of the revised
Public Safety Plan (PSP) for PG&E’s DeSabla-Centerville Hydroelectric Project, Federal
Energy Regulatory Commission (FERC) No. 803 submitted to FERC on March 27, 2025. The
DeSabla-Centerville PSP was prepared for PG&E by Kleinschmidt & Associates. PG&E has
reviewed the PSP and concurs with the content and findings presented therein.
PG&E previously provided FERC a revised PSP in a letter dated May 18, 2015. FERC
requires an updated PSP every 10 years, and (Enclosure 1) of this filing fulfills that
requirement. A review of all PG&E PSPs is completed annually to ensure that they accurately
represent existing recreation and public safety features within our projects.
Should you have technical questions concerning this matter, please contact PG&E public
safety specialist, Renée Fernandez-Lipp, at (415) 542-6090.
Sincerely,
Renée Fernandez-Lipp

1.0 INTRODUCTION AND PURPOSE
This Public Safety Plan (PSP) for the DeSabla-Centerville Project, Federal Energy
Regulatory Commission (FERC) No. P-0803 (Project), describes how Pacific Gas & Electric
Company (PG&E) will meet the requirements of 18 Code of Federal Regulations (CFR)
12.52, which require PG&E to “install, operate, and maintain any signs, lights, sirens,
barriers, or other safety devices that may reasonably be necessary or desirable to warn
the public of fluctuations in flow from the project or otherwise to protect the public in the
use of the project lands and waters.”
This PSP identifies the safety signage and safety measures installed at the Project to
inform the public of potential hazards and to help mitigate any potential injury to those
who use project lands and waters. This includes safety measures relating to recreation or
any potential hazards relating to Project structures and operations. Where appropriate,
topographic maps or Google Earth images of the site locations have been included to
identify the safety measure present at each location.

2.0 GENERAL PROJECT DESCRIPTION
The Project is divided into three developments: Toadtown, DeSabla, and Centerville. The
areas that have public safety features are described below generally following the flow of
water through each development. The Toadtown development diverts water from the
West Branch of the Feather River (WBFR), the DeSabla development diverts water from
Upper Butte Creek as well as using the outflow of the Toadtown development, and the
Centerville development diverts the flow of Butte Creek downstream of the DeSabla
development.

February 2025 2-2 Kleinschmidt Project Control No. 0836016.06
2.1 TOADTOWN DEVELOPMENT
The Toadtown development consists of: Round Valley and Philbrook Dams and Reservoirs,
Hendricks Diversion Dam and Canal, Toadtown Powerhouse, two distribution lines, and
several short access roads.
2.1.1 Round Valley Dam and Reservoir
Round Valley Reservoir (also known as Snag Lake) has a maximum depth of about 25 feet,
has a gross and useable storage of approximately 1,200 ac-ft with a spillway elevation of
5,651.1 feet. The dam has a simple overflow spillway and has no gates or flashboards.
2.1.2 Philbrook Dam and Reservoir
Philbrook Reservoir has a maximum depth of about 60 feet, with a gross and usable
storage of approximately 5,000 ac-ft, a normal maximum water surface elevation of
5,552.5 feet, and has a surface area of 173 acres. Philbrook Reservoir has a single outlet
conduit, located under the main dam near the maximum section. This is a 33-inch
diameter riveted steel pipe, 460 feet long. The intake, located a short distance upstream
from the dam, is submerged. It consists of a 17-foot high, vertical, concrete pipe, 8 feet in
diameter, the open top of which is guarded by a sloping steel grizzly. There is no intake
control gate. Water releases are controlled by a manually operated, 30-inch diameter
needle valve at the downstream end of the pipe.
Philbrook Dam is formed by two adjacent, compacted earthfill dams. A small auxiliary dam
is located about 170 feet to the right of the main dam. The main dam is about 87 feet
high and 850 feet long; the auxiliary dam is about 24 feet high and 470 feet long. The
upstream slopes are partially covered with placed rock riprap, which extends from the
crest at elevation 5,556.4 feet down 24 feet to elevation 5,532.4 feet.
2.1.3 Philbrook Spillways
To the right of the auxiliary dam are two spillways. The original spillway has removable
flashboards. It is 29.67 feet wide and has five flashboard bays. Flashboards up to 5.1 feet
high are installed on the crest, which is at elevation 5,547.4 feet. The second spillway is
located 50 feet to the right of the first spillway. It has a single, manually operated, radial
gate (10.75 feet high by 14.75 feet wide). The crest of the gated section is at elevation
5,542.7 feet. The spillways discharge into the same channel, which joins Philbrook Creek
Document Accession #: 20250709-5060 Filed Date: 07/09/2025
February 2025 2-3 Kleinschmidt Project Control No. 0836016.06
about 1,000 feet downstream from the dams. They have a maximum discharge capacity
at zero freeboard of about 4,100 cubic feet per second (cfs).
2.1.4 Hendricks Diversion Dam and Canal
Hendricks Diversion Dam is located on the WBFR about 12 miles below Round Valley
Dam. Hendricks Diversion Dam is a concrete gravity dam approximately 15 feet high with
an overflow spillway section 98 feet wide and has a crest elevation of 3,256 feet.
Hendricks Canal originates at the Hendricks Diversion Dam and is 8.66 miles long and
composed mostly of earthen ditch with several flume and tunnel sections. Hendricks Canal
carries up to 125 cfs.
2.1.5 Toadtown Powerhouse
The Hendricks Canal ends at a small intake structure that feeds the 54-inch diameter,
1,512 feet long concrete cylinder Toadtown Powerhouse penstock. Rapid Pipe, a 48-to-
24-inch diameter, 1,499 feet long steel pipe also connects to the intake structure and acts
as a by-pass. Toadtown Powerhouse is a reinforced concrete building approximately 28
feet by 44 feet, housing one turbine-generator unit. The main floor is at elevation 2,825.0
feet. The turbine- generator unit has a horizontal Francis turbine with a normal maximum
gross head of 185 feet, a rated flow of 134 cfs, with a rated capacity of 1,800 kw. The
normal operating capacity of the powerhouse is 1.5 MW. The powerhouse is designed for
unattended operation with float control from the water level at the Toadtown intake
structure.
Where the Hendricks Canal ends, there is a 1,500-foot-long, 12kV Toadtown Transmission
Line connecting to PG&E’s Oro Fine Circuit 1101. This tap provides a safe vertical clearance
of at least 40 feet to account for fluctuating water levels.
2.2 DESABLA DEVELOPMENT
The DeSabla development consists of Butte Creek Diversion Dam and Canal, Toadtown
Canal, DeSabla Forebay, and DeSabla Powerhouse.
2.2.1 Butte Creek Diversion Dam and Canal
Water is diverted from Butte Creek at the Butte Creek Diversion Dam, a concrete arch dam
approximately 50 feet high, into the Butte Canal. The dam has an overflow spillway at an
elevation of 2,884 feet.
Document Accession #: 20250709-5060 Filed Date: 07/09/2025
February 2025 2-4 Kleinschmidt Project Control No. 0836016.06
The 11.4-mile Butte Creek Canal has a capacity of approximately 91 cfs. Butte Canal
consists of sections of earthen berm, gunite, tunnels, a siphon, and flume. Approximately
0.7 miles above DeSabla Forebay, Butte Canal and Toadtown Canal join. At this juncture,
canal capacity increases to 191 cfs.
2.2.2 Toadtown Canal
Toadtown Canal is in essence the continuation of Hendricks Canal from the tailrace of
Toadtown Powerhouse to Butte Creek Canal above DeSabla Forebay. The Toadtown Canal
is about 2.4 miles long and is principally an earthen canal with a capacity of 125 cfs.
2.2.3 DeSabla Forebay and Dam
DeSabla Forebay is formed by an earthen embankment approximately 50 feet high and
250 feet thick at the base, with a width of 100 feet at the crest. A spillway canal leading to
a small ravine is located just north of the dam. The spillway elevation is 2,755 feet. DeSabla
Forebay has an original capacity of 188 ac-ft; however, sedimentation has reduced this
capacity to about 163 ac-ft. DeSabla Forebay has a surface area of about 15 acres at full
capacity and is a regulating facility for DeSabla Powerhouse. The powerhouse and
associated intake are float-controlled and the forebay fluctuates minimally (typically less
than 0.2 feet) during normal operations and rarely spills.
2.2.4 DeSabla Powerhouse
DeSabla Powerhouse is fed by water from DeSabla Forebay through a welded steel
penstock, and discharges water directly into Butte Creek. DeSabla Powerhouse is a
reinforced-concrete structure with a control building approximately 26.5 feet by 41 feet,
with one turbine-generator unit. The main floor is at elevation 1,222.5 feet. The turbine
unit is a 25,000 hp Pelton horizontal turbine with a normal maximum gross head of 1,530
feet and a design flow of 191 cfs. In addition, there is a 0.25-mile-long, 60kV DeSabla-
Oroville Transmission Line extending from DeSabla Powerhouse to a junction with the
Oro Fino 60kV Tap Line and appurtenant facilities.
2.3 CENTERVILLE DEVELOPMENT
The Centerville Development consists of the Lower Centerville Diversion Dam and Canal,
the Upper Centerville Canal, and the Centerville Powerhouse.

February 2025 2-5 Kleinschmidt Project Control No. 0836016.06
2.3.1 Lower Centerville Diversion Dam and Canal
The Lower Centerville Diversion Dam (LCDD) is located on Butte Creek just below the
DeSabla Powerhouse and diverts up to approximately 183 cfs from Butte Creek into the
Lower Centerville Canal. LCDD is a concrete arch dam about 12 feet high with an overflow
spillway at crest elevation 1,146 feet.
Lower Centerville Canal is approximately 8 miles long and is composed of earthen canal
and several flume sections and has a capacity of 180 to 190 cfs.
2.3.2 Upper Centerville Canal
The Upper Centerville Canal originates at DeSabla Forebay and was historically used as an
alternate route to direct water to Centerville Powerhouse when DeSabla Powerhouse was
out of service. The Upper Centerville Canal ends at Helltown Ravine where water can be
released and then captured where Helltown Ravine crosses Lower Centerville Canal. The
Upper Centerville Canal has not been used to carry water for power generation for many
years and currently carries only a few cfs for local water users.
2.3.3 Centerville Powerhouse
Centerville Canal ends at a 27 feet by 37 feet concrete header box, which feeds water to
riveted steel penstocks and a spillway which is used in the event a generator at Centerville
Powerhouse “trips” offline. Centerville Powerhouse is a concrete reinforced stone building
approximately 32 feet by 109 feet with two turbine-generator units. The main floor is at
elevation 475.0 feet. The combined two units have a normal maximum gross head of 590
feet, a flow of 183 cfs, and a total normal operating capacity of 6.4 MW. A single 6,000
kVA transformer steps up voltage to 60,000 volts and power is delivered to the
interconnected system at the adjacent Centerville switchyard.

3.0 PROJECT RECREATION RESOURCES AND FACILITIES
Recreation facilities and opportunities at the Project Area are largely enjoyed by visitors
originating from Butte County. The Project’s primary recreation facilities and opportunities
are focused around Philbrook Reservoir and DeSabla Forebay.
3.1 TOADTOWN DEVELOPMENT
3.1.1 Round Valley Reservoir
Under current Project operations, water releases from the reservoir typically begin in June
and the reservoir is completely drained in about one month’s time. As the reservoir is
drained completely and rapidly each year, the reservoir has little recreation attraction and
contains no developed recreation facilities.
3.1.2 Philbrook Reservoir
The primary recreational activities that occur at Philbrook Reservoir are camping, fishing,
boating, picnicking and general shore use. The majority of boating use is by anglers.
Boating on the reservoir is primarily by smaller low or non-powered watercraft, although
high-speed boats and personal watercraft occasionally boat on the reservoir. The Butte
County boating ordinance prohibits boating within 300 feet of the dam and exceeding a
5-mph speed within 100 feet of swimmers, small boats, and docks/swim platforms. Butte
County ordinance also includes the prohibition of motorized boats on lakes of less than
300 surface acres, if posted appropriately.
The reservoir generally fills in the late spring from snowmelt runoff. The beginning of the
reservoir’s summer recreation season is dependent on the timing of snowmelt, which
generally occurs by the end of May. Annual Operations and Maintenance Plans prepared
by the Licensee in consultation with National Oceanic Atmospheric Administration,
California Department of Fish and Wildlife, State Water Resources Control Board and the
United States Fish and Wildlife Service, have generally called for the reservoir to be drawn
down at a relatively constant rate during the summer months to move water over to Butte
Creek to support the spring run salmon during their spawning and holding periods. In
addition, as part of its normal operating procedure, the reservoir’s elevation is generally
held above 5,516-foot elevation (750 acre-feet) until mid-September in order to ensure
the minimum stream flow requirement can be provided through the remaining fall season.

3.2 DESABLA DEVELOPMENT
3.2.1 DeSabla Forebay
DeSabla Forebay is located on the west side of the Skyway approximately 9.3 miles north
of the town of Paradise and is a popular fishing spot with local residents. The water surface
elevation of the forebay is held relatively constant as part of Project operations. Only non-
power and low-power boats have been observed using the forebay. As with Philbrook
Reservoir, the forebay, if posted appropriately, could prohibit motorized boating. CDFG
regulations allow year-round fishing at the forebay.
Public shoreline use is primarily focused on the east shore and on the dam located along
the reservoir’s south side. The DeSabla Group Picnic Area is located across the Skyway
from the forebay and is available for public reservation during high-peak times of the
year. The site contains a group barbecue, picnic tables, running water, and a vaulted toilet
facility. Camp groups are allowed to use the site, but overnight camping is not permitted
as this is a day-use facility only. Signs on the forebay's shoreline indicate that public
restrooms are available for use at this picnic area.

4.0 PUBLIC SAFETY MEASURES
As recreation and residency are common near PG&E waterways and facilities, employees
must ensure that the proper safety signage and safety measures are in place to inform
the public of potential hazards and to mitigate potential injury to the public. This section
includes detailed public safety measures employed within each development at the
DeSabla-Centerville Project. Figure A-1 (Appendix A) provides an overview of the
DeSabla-Centerville Project.
4.1 TOADTOWN DEVELOPMENT
4.1.1 Round Valley Dam and Reservoir
There is a locked gate to prevent vehicle access to dam and signage which indicates
private property. Additional safety signage around the boating safety barrier indicates the
potential for rising water and unstable weather conditions. The boating safety barrier
consists of a floating timber boom barrier across the spillway approximately 30 feet
upstream of the road crossing the spillway. The boom is anchored by steel pins driven
into the ground above the high-water line. There are multiple danger signs located on
the spillway indicating “Falling Hazard - Watch Your Step.”
Figure A-2 (Appendix A) and Table B-1 (Appendix B) provide a summary of the signs
present at the site.
4.1.2 Philbrook Reservoir, Dam, and Spillway
There is restricted access signage to prohibit access to the dam and alert the public of
sudden water discharge. Additional safety signage around the boat launch and boating
safety barrier indicates the potential for rising water and unstable weather conditions. The
boating safety barrier consists of a floating plastic buoy boom across the channel to the
two spillways. The boom is fixed at both ends by concrete anchors. Multiple hazard signs
located along the Philbrook spillways and associated facilities related to water discharge
and private property restrict public access
Figure A-3 (Appendix A) and Table B-2 (Appendix B) provide a summary of the signs
present at the site.

4.1.3 Hendricks Diversion Dam and Canal
Public vehicle access across the dam is restricted by a locked access gate. Restricted access
signage prohibits access to the dam and alerts the public of sudden water discharge.
There is a high-water alarm at the dam for potentially hazardous conditions downstream
of the dam that will also provide water and flow data to the Caribou Switching Center for
monitoring purposes. Fencing is installed around operating mechanical equipment with
locked gate access to the dam. The access roads have private property signs and narrow
walkway cautions. In addition, there are multiple “Danger” signs located along Hendricks
Canal related to sudden water discharge, private property notices, and restricted access
to the canal and tunnels. The areas surrounding the canals have a mix of unrestricted
public access and locked gate access, which allows only authorized personnel access.
