except when releases from the 250 acre-feet minimum pool are necessary to maintain

Volume of Discharge in cubic feet per second (cfs) during normal and dry water years1 Point of Discharge Normal Dry2 Time Period3 Philbrook Reservoir [BW-3] 2.0 2.04 Hendricks Head Dam [BW-40] 15 7 These flows may be temporarily modified if required by operating emergencies beyond the
control of the Licensee, and for short periods upon mutual agreement between the
Licensee and the California Department of Fish and Game Background The Philbrook Reservoir storage (5,000 acre-feet) is utilized during the summer holding period of
CVSRCS to provide additional flows to Butte Creek. Philbrook Reservoir is located on the West
Branch Feather River (WBFR) watershed. Flows released from Philbrook Reservoir, along with
other flow within the WBFR , are diverted into the Hendricks Canal at the Hendricks Diversion Dam (Figure 1). Depending on water availability , w ater diverted from the WBFR at the Hendricks
Diversion Dam can increase the total flow available in Butte Creek below DeSabla Powerhouse up
to 40% in July through September. To reduce potential temperature impacts, PG&E operates the project in such a way as to reduce
water residency time within DeSabla Forebay (Forebay). This is achieved by providing a minimum
of 60 cfs to the Forebay via Butte, Hendricks, and Toadtown Canals . In August 2023, Butte Canal sustained damage that removed the canal from service. PG&E has
made the determination to keep the canal out of service indefinitely . Th e loss of flow from the Butte
Canal will result in decreased flows through the forebay with only source of water diverted from the
WBFR at the Hendricks Head Dam into the Hendricks Canal . This temporary flow modification request will help PG&E meet this target flow through the forebay during the summer months. In a ddition to the loss of the Butte Canal , results of recently completed seismic stability analyses
for Philbrook Dam indicated unsat isfactory performance of the dam under the seismic loading
scenarios considered when the reservoir is at its normal maximum water surface elevation
(NMWSE) of 5,552.5 feet (National Geodetic Vertical Datum of 1929 [NGVD29]). Considering these results, the potential downstream consequences associated with the risk of post-seismic
deformation could lead to uncontrolled release of the reservoir. A reservoir restriction has been
established at Philbrook as an interim risk reduction measure (IRRM) until a long-term solution has
been selected and implemented. PG&E will manage the Philbrook Reservoir at a target elevation
1 Discharge is in cubic feet per second (cfs). 2 A dry water year is any 12-month period beginning May 1 in which the natural runoff of the Feather River at Oroville
for the April 1 to July 31 period, as forecast on April 1 by the State of California Department of Water Resources, and
as may be adjusted by the State on May 1, will be 50 percent of less of the average for such period as computed by the
State for the 50-year period used at that time. If during a designated dry year, the February 1 or later water year
prediction indicates that dry year conditions no longer prevail, Licensee will resume normal year flow releases
immediately upon notification by the California Department of Fish and Game. 3 Unless otherwise noted, the time period is year-round. 4 When inflow to Philbrook Reservoir is less than 0.1 cfs, a minimum flow of at least 0.1 cfs shall be discharged.

of 5,5 42.7 feet NGVD29 , which is 9.8 feet below the NMWSE and corresponds to a decrease of
approximately 1,600 acre-feet of its storage capacity. Figure 1- Locations of Philbrook Reservoir and He ndricks Head Dam The California Department of Water Resources (DWR) issued the April Bulletin 120 report.
According to the report, the water year type for the DeSabla-Centerville Project will be “Normal,” with an estimate of 106 % of average. The water year type is determined in May; however, a t this
point in the season, it is unlikely that the water year type would move t o a dry classification, which
is characterized as flowing below 50% of average. Even with decreased availability of water from the Philbrook reservoir restriction, the water year type in 2025, together with this variance should
assist in PG&E’s efforts to maintain 60 cfs of inflow into the Forebay. Document Accession #: 20250506-5165 Filed Date: 05/06/2025

Operations and Maintenance Plan On August 21, 1997, FERC issued an Order placing temperature restrictions (17º Celsius at Round
Valley and 18º Celsius at Philbrook) on the releases from these dams. On August 20, 1998, FERC
revised its Order to allow for modification of the criteria upon mutual agreement of NMFS, CDFW,
and USFWS. An Operation and Maintenance Plan and an annual meeting held ahead of the
summer holding period are the mechanisms by which PG&E consults with the agencies to gain
mutual agreement on releases from these dams. To advance collaboration, PG&E also in cludes the SWRCB and USFS in this consultation process. The population of CVSRCS in Butte Creek is the largest remaining self-sustaining population of
this threatened species in California. Under the annual Operations and Maintenance Plan, PG&E coordinates an annual meeting ahead of the holding period with the Resource Agencies and holds
weekly conference calls with the Resource Agencies during the CVSRCS’s holding period. The weekly conference calls are from early June through mid-September (as needed). During these conference calls, the Resource Group (PG&E an d Resource Agencies) will discuss the results of
pre-spawning mortality surveys (if provided by CDFW), meteorological forecasts, water
temperatures recorded by CDFW at Quartz Bowl Pool, project flows, and storage in Philbrook
Reservoir. Proposed Variance The proposed variance includes changing instantaneous minimum instream flow (MIF)
requirements at BW-40 from 15 cfs to 7 cfs measured as an average MIF over a 48-hour period, as
listed in Table1 below . Once approved, PG&E would like to implement the temporary variance at
the Hendricks Head Dam (BW-40) beginning July 1, 2025, and complete the variance by
September 30, 2025. Once approved, PG&E would like to implement the variance at Philbrook
Reservoir (BW-3) as soon as approval is received and would complete the variance by September
30, 2024. Table 1: License required and variance request flows. Compliance

of 2 cfs Normal WY, 2 cfs dry WY Average MIF over 48 hour - target between 1 and 2 cfs The variance at Hendricks Head Dam will maximize the delivery of flow released from Philbrook Reservoir to Butte Creek. All Philbrook release flow will be utilized instead of some being used to
buffer flow to meet the higher instantaneous MIF requirement. With the implementation of the
proposed variance, flow through the Forebay will also be increased. Heating in the Forebay is
caused by exposure to solar radiation and natural high air temperatures during the summer holding
period as it travels through the forebay. Increased flow will minimize residence time in the forebay
thereby decreasing heating effects within the Forebay . Thus, this action of providing as much flow
Document Accession #: 20250506-5165 Filed Date: 05/06/2025
Debbie-Anne Reese, Secretary May 6, 2025 Page 5
from the WBFR through the Hendricks Canal, in the absence of the Butte Canal will help minimize
heading in the Forebay. The following conditions will be in effect during the variance time frame: 1. PG&E will continue to hold weekly CVRCS meetings with Resource Agencies 2. Decisions on when and how to implement the variance flows, as well as any flow changes
under this variance would be done in consultation with PG&E staff and the Resource
Agencies prior implementing . 3. PG&E will maintain an MIF of 7 cfs, measured at BW-40, as agreed upon with PG&E staff
and the Resource Agencies 4. PG&E will monitor and provide weekly flow changes to the Resource Agencies for gauging stations BW40 and BW3 during weekly CVRCS Holding Period meetings. 5. PG&E will promptly notify the Resource Agencies of any event that significantly inhibits or
impairs the release structures from maintaining a 7 cfs MIF. Biological Impacts on CVSRCS PG&E fisheries biologists have reviewed this variance proposal and believe that the proposed flow
changes would benefit the holding CVSRCS by maximizing the volume of water that can be
delivered to Butte Creek from the WBFR during periods especially when the Butte Canal is offline. In addition to the CVSRCS, DeSabla Reservoir is an important recreational location for residents in
the area and rainbow trout are stocked during the spring and early summer months. This variance
will also support that fishery and the recreationalist who d epend on it. The material informing this request includes the following: • The holding pattern of adult CVSRCS since the Lower Centerville Powerhouse was taken
off-line (2011), has shifted to more of the population holding in the upper reaches. It is
expected that >95% of adults will hold in the upstream four miles of habitat due to water
temperatures. This concentration of individuals increases the potential breakout of
disease among a larger portion of the holding population. • The variance will help provide a larger volume of water through Butte Creek. This is
important to minimize the effects of high ambient air temperatures which drive water
temperatures. Higher water temperatures result in higher potential and severity of a
disease outbreak. This is particularly true with an increase in population density. • Increasing inflow from Hendricks Canal shortens the travel time through the Forebay thus decreasing the heating of water by minimizing exposure to solar radiation. This minimizes
the temperature of the water that enters Butte Creek. Agency Consultation On March 10, 2025 , PG&E hosted a meeting with the Resource Agencies to discuss the water
management constraints and options for support ing the population of CVSRCS during the summer
holding period. This variance request supports PG&E’s and the Resource Agencies ’ efforts of ensuring the availability of cold-water storage in Philbrook Reservoir to support the population and
minimizing water temperature increases in the Forebay. Document Accession #: 20250506-5165 Filed Date: 05/06/2025
Debbie-Anne Reese, Secretary May 6, 2025 Page 6
On April 1, 2025, PG&E provided the Resource Agencies with a draft of this request. CDFW,
USFWS, and NMFS provided concurrence on April 3, 2025, April 28, 2025, and April 29, 2025,
respectfully . CDFW provided a comment concerning the JCO; however, this comment does not
relate to or influence PG&E’s ability to implement the requested variance. The consultation record is provided as (Enclosure 1). Conclusion PG&E respectfully requests changing instantaneous MIF requirements at BW-40 from 15 cfs to 7
cfs measured as an average MIF over a 48-hour period. This temporary flow modification will provide flexibility to transfer the maximum amount of water into the Hendricks Canal from the
WBFR to increase flow through the DeSabla Forebay to Butte Creek during the hottest part of the
summer holding period for CVSRCS in Butte Creek. If you have any question s regarding this matter, please contact PG &E’s license coordinator, Sky

Hi Sky --
NMFS does not oppose the proposed temporary flow modification as written in the Draft 2025 Minimum
Instream Flow Temporary Amendment. The temporary flow modification is similar to what has been
implemented in previous years in order to maximize the amount of water available to support holding
conditions for spring-run Chinook salmon (SRCS) in Butte Creek. Similar to previous years, NMFS will
provide technical assistance with PG&E and others during this year’s weekly CVSRCS Holding
Meetings.
Please let us know if you have any questions.
Thanks -

Hello Sky,
The California Department of Fish and Wildlife (CDFW) is ok with the variance as written and
supports PG&E requesting the variance from FERC; however, CDFW requests PG&E
reconsider the proposed operation of Philbrook Reservoir. Specifically, CDFW requests
PG&E consider filling Philbrook Reservoir to full capacity this spring to ensure there
is as much water as possible available this summer to help manage temperatures in
the holding reaches of Butte Creek to support adult spring-run Chinook salmon
(SRCS). CDFW’s understanding is that infrastructure conditions at Philbrook Reservoir have
not changed during the last year; however, PG&E recently made a determination based on a
new analysis that Philbrook was unsafe to fill and therefore would be operated at reduced
capacity through the summer. PG&E did not provide any documentation or otherwise discuss
specific changes in condition of the reservoir infrastructure that led to this determination;
therefore, CDFW requests PG&E reevaluate and reconsider operating Philbrook Reservoir at
full capacity.
Independent, genetically unique populations of SRCS have been extirpated from all but three
tributaries of the Sacramento River; Butte, Mill, and Deer creeks, with Butte being the largest
remaining of the three populations and a stronghold for the species. Historically, SRCS held
over summer in headwaters of their natal streams but are now limited to holding at relatively
low elevations and thus more vulnerable to mortality. SRCS adults migrate up the Sacramento
River from late January, reaching spawning areas from February through June. The majority of
SRCS return to spawning grounds three years after emerging from their freshwater habitats.
SRCS in Butte Creek hold in deep pools maturing during summer. This requires adequate flow
and cold water to survive until spawning in fall. Due to present climate stress, pre-spawn
holding mortality is associated with elevated water temperatures and pathogen outbreaks,
which occurred in Butte Creek in 2002, 2003 and most recently, 2021, where an estimated
19,773 SRCS adults were lost. Butte Creek SRCS population estimates over the last three
Document Accession #: 20250506-5165 Filed Date: 05/06/2025
years (2022-2024) have been 2,900, 44, and 28, respectively. These markedly low population
numbers have left Butte Creek SRCS on the brink of extirpation which puts the species at
higher risk of extinction. The 2022 population of 2,900 SRCS adults is the last three-year cohort
that could potentially produce a sustainable population of Butte Creek SRCS. The progeny of
this brood year is returning this spring, 2025. It is imperative that enough cold water is available
to help this population survive through the summer until spawning in the fall. Ensuring
Philbrook Reservoir is operated at maximum capacity will help facilitate adequate
holding temperatures in Butte Creek this summer to reduce the potential for
prespawn mortality and maximize the number of adult SRCS that successfully
spawn in the fall.
