This monitoring is conducted as set forth in Condition 10 of Appendix A of Regulatory Commission (FERC) Project No. 2107 issued December 17, 2018 (PG&E 2018). 1.1 P ROJECT S ETTING The North Fork Feather River (NFFR) watershed is located in northeastern California (see Figure 1) within the greater Sacramento River watershed, and drains a large portion of the eastern Sierra-Cascade geomorphic area in California. The NFFR extends from its headwaters on the southeastern slope of Lassen Peak to Lake Oroville, while traversing Lassen, Plumas, and Butte counties. The North, Middle, and South forks of the Feather River flow into Lake Oroville (formed by Oroville Dam); the confluence of these tributaries is contained within the reservoir, so the main stem of the Feather River flows out of Lake Oroville. The Poe Hydroelectric Project is located on the North Fork Feather River in Butte County California (Figure 1). Waters entering the Poe Project are derived from a series of major hydroelectric facilities that utilize the water resources of the NFFR and its tributaries for hydroelectric power generation. These project (FERC 2105) and RCC Project (FERC 1962) and Bucks Creek Project (FERC 619). The monitoring area encompasses approximately ten miles of the lower NFFR immediately upstream of Lake Oroville (FERC 2100 - Department of Water Resources). Water in the NFFR is diverted to Poe Powerhouse from the Poe Diversion Dam. This diversion creates a 8.0 mile long bypass reach (Poe Reach). Water temperature monitoring in the Poe Reach was conducted in 1999, 2000 and 2003, during the relicensing effort for the project. The data collected is included in Appendix E2-3 of the application for the new license for the Poe Project (PG&E 2003). In addition, water temperature has been measured annually in the Poe Reach from 2003-2018 coincident with the temperature monitoring required by Condition 4C. 1.0 Introduction 1 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report Figure 1. Location of the Poe Hydroelectric Project in northeastern California. 1.0 Introduction 2 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report in the Rock Creek-Cresta Project (FERC No. 1962). This data was not included in the annual reports associated with that project, and was subsequently summarized in first annual report submitted under the Poe Temperature Plan (PG&E 2021). 1.2 G OAL AND O BJECTIVES The goal of the water temperature monitoring program is to document temperature in the Poe Reach following changes in minimum instream flow (MIF) rates in accordance with the new FERC license. The temperature data from this monitoring effort will be made available for other biological monitoring efforts, such as the Poe Bypass Reach Fish and Benthic Macroinvertebrate Monitoring Plan and the Foothill Yellow-Legged Frog Monitoring Plan. Specific objectives are: 1. Describe seasonal and daily water temperature regimes at multiple locations along the Poe Reach from April 1 through October 31 of each year of the license, or until deemed necessary by the State Water Resources Control Board (SWRCB). If safe access to the monitoring sites is not possible by April 1, the temperature monitoring equipment will be installed as soon as it is safe to access the sites. 2. Provide an annual report that includes water temperature and corresponding flows measured in the Poe reach, to the Agency Representatives, following the completion of each annual monitoring campaign. 3. Evaluate the water temperature data no later than 12 years after implementation of the new Canyon Dam flow releases associated with the UNFFR Project to determine if changes in instream flows are needed. 1.0 Introduction 3 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report 1.3 S COPE OF R EPORT The 2021 water temperature monitoring report follows the requisites outlined in the Water Temperature Monitoring Plan (PG&E 2019) to include a description of: Sampling locations Monitoring Methods QA/QC findings Monitoring results (Tabular summary and graphic presentation) Problems encountered History of temperature data collected from field studies since 2003 1.4 C ONSULTATION The draft 2021 monitoring report was emailed to the United States Department of Agriculture - Forest Service (Forest Service), United States Fish and Wildlife Service (USFWS), California Department of Fish and Wildlife (CDFW), SWRCB, State Water Board, and Plumas Countyon February 24, 2022.

Details about each station are included in Table 1. Figure 2 shows the location of all monitoring stations within the Project Reach. 2.1.2 Water Temperature Measurement Water temperature was continuously monitored from April through October 2021. All thermographs/data-loggers were set to record/store instantaneous water temperature at 15-minute intervals. All stored data was downloaded during monthly site visits and processed to generate hourly average and daily maximum, minimum, and mean water temperature values. Water temperature sensors were deployed in well-mixed areas of the stream with elevated velocity and adequate depth to ensure representative measurements. Each water temperature recorder was deployed inside a protective metal housing which was locked to the stream bank or in-channel substrate with a steel chain/cable. All monitoring locations were chosen based on safe accessibility, and acceptable security from vandalism or theft. The 2021 monitoring program used Vemco Minilog-IIT data-loggers at all locations. The Vemco Minilog IIT loggers are capable of recording temperatures accurate to ± 0.1°C between - 3°C and 35°C. A record of data-logger/sensor deployment is contained in Table B-1 (Appendix B). 2.2 Q UALITY A SSURANCE AND C ONTROL P ROCEDURES To verify the operation and accuracy of the temperature recorders, all units were calibrated using an American Society for Testing and Materials (ASTM) reference thermometer, both prior to and following removal from in situ deployment. All instruments were calibration adjusted to achieve 2.0 Methods Summary 5 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report Table 1.

The calibration and QA/QC information associated with the water temperature monitoring effort is also included in Table B-2 (Appendix B). 2.3 P OE R EACH S TREAM F LOW Project-specific powerhouse and in-stream flows were obtained from existing PG&E permanent monitoring stations. The flow in the Poe Reach is monitored at PG&E Gage No. NF-23 (USGS Gage No. 11-4045.00). Flow data from Poe Powerhouse is from internal PG&E generation data. The methods used to collect data at both of these locations is beyond the scope of this document. 2.4 P OE P ROJECT M ETEOROLOGY Meteorological conditions in the project area were defined using data from stations located at Poe Powerhouse and Bucks Creek Powerhouse. As stipulated in the Water Temperature Monitoring Study Plan (PG&E 2019), a seasonal meteorological monitoring station was installed at Poe Powerhouse on April 15, 2021. This station recorded seasonal meteorological at the terminal end of the Poe Reach. Meteorological parameters included air temperature, wind speed and direction, relative humidity, and solar radiation. The Bucks Creek Powerhouse meteorology station is located approximately 10 miles upstream of Poe Dam Data from this station (identified as BUP in the California Data Exchange Center (CDEC) website) were collected and compiled Meteorological Department. The methods used to collect the data are outside the scope of this document. 2.0 Methods Summary 8 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report 3.0 RESULTS 3.1 M ONITORING I SSUES There were no issues with instrument operation or vandalism. The Dixie Fire effected watershed access, and operational conditions within the Project watershed as well in all upstream hydro- electric projects (Upper NFFR and Rock Creek-Cresta). The Poe Project was not affected by the fire directly, meteorological impacts likely occurred related to smoke in the canyon. 3.2 2021 W ATER Y EAR T YPE The North Fork Feather River watershed flows are often different from those characterizing the greater Sacramento River Basin as defined in the DWR runoff index. However in 2021 the two were classified similarly. The Department of Water Resource (DWR) classified 2021 as a Critically Dry year with regard to the greater Sacramento River Basin (CDEC 2022). In accordance with Condition No. 5B, Water Year Type as outlined in the Rock Creek-Cresta License, the 2021 water year waCritically Drythe May 1 estimated inflow to Lake Oroville (Bulletin 120 CDEC 2021). 3.3 W ATER T EMPERATURE M ONITORING In 2021 water temperatures were continuously monitored between April and October at locations identified in the Study Plan.

This station represents conditions near a Foothill Yellow-legged frog (FYLF) breeding site and was installed after the breeding period to avoid disturbances to exist egg masses. Mean daily water temperatures at WT-2 for the period April 1 through October 31 ranged from 9.7 to 23.2C (Table 2). The maximum hourly average th temperature (23.7C) occurred on July 12 , 2021 (Appendix C1). The thermal regime at this location is a function of the relatively short distance downstream from Poe Dam and upstream of any inflow from major tributaries. As a result, the diel range in temperatures is similar to WT-1, with an average diel fluctuation of 0.8°C (Table 2).

This station represents conditions in the NFFR after flows from the Poe Reach and powerhouse have been fully mixed. Mean daily water temperatures at WT-6 for the period April 1 through October 31 ranged from 10.0 to 23.6C th (Table 2). The maximum hourly average temperature (24.5C) occurred on July 14 , 2021 (Appendix C1). The thermal regime at this station is downstream of the large inflow from the Poe Powerhouse, and as a result, the diel range in temperatures is less than those observed at stations in the middle and end of the Poe Reach (WT-4 and WT-5). The average diel fluctuation at Station WT-6 was 1.3°C (Table 2). Figure 8 presents daily maximum, minimum, and mean water temperature from Station WT-6. Figure 8.

The figure illustrates the similar temperature response in the upper and middle segments of the Poe Project (WT-1 to WT-4) and the influence of ambient air temperature on water temperature. Mean daily water temperatures at Station WT-4 (Bardees Bar) were 0.3°C cooler to 0.7°C warmer than those observed at WT-1 (initial condition). Mean daily temperatures at the terminal station in the Poe Reach (WT-5), exhibited values that trended along with other stations, but were warmer than the upstream reaches for the June through August period. Mean daily water temperatures at WT-5 ranged from 0.2°C cooler to 1.7°C warmer than those observed at WT-1 (initial condition). Water temperature began to converge throughout the reach at the end of September (Appendix C1). Mean daily water temperatures downstream of Poe Powerhouse were was similar in value and range to those observed in the upper reaches of the project. This is to be expected as the immediate source of flows for both WT-1 and the powerhouse is Poe Reservoir. Conditions at WT-6, approximately 0.25 miles downstream of Poe Powerhouse are driven largely by the high flows coming from the powerhouse. 3.0 Results 18 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company 2 202 April . 2107 2021 - s RC No. e m the Poe Project of the NFFR with mean daily air 19 , FE ) , Pacific Gas and Electric Company Poe Project 107 22 © 20 No. 2 Annual Report Bucks Creek Powerhous 1 e water temperature fro Project 202 Poe and Project (FERC Comparison of daily averagtemperatures from . 9 Poe HydroelectricWater Temperature Monitoring Results Figure 3.0 Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report 3.5 M AXIMUM W EEKLY A VERAGE T EMPERATURE (MWAT) The maximum weekly average temperature (MWAT), which is the maximum 7-day average value measured during ae specified monitoring period is a method of roughly identifying habitat suitability for identified species. The MWAT is a useful index for identifying the maximum temperatures in a stream reach, without overly being influenced by the maximum temperature of a single day. The MWAT value for each month (April through October) and for the duration of the 2021 monitoring period for each station are presented in Table 3. The annual MWAT value for the initial condition (WT-1: below Poe Dam) in 2021 was 23.0°C. For the terminal condition in the Poe Reach (WT-5: upstream of Poe Powerhouse), the MWAT in 2021 was 23.7°C.

Appendix A is the State Water Resources Control Board (SWRCB) Final 401 Water Quality Certification Conditions. The requirements are incorporated into License Article 401. Attachment 1 and 2 contain the language from the two documents as applicable to this Plan. The Poe Project is located within the North Fork Feather River Basin, which contains extensive forested lands and is sparsely populated. section of the North Fork Feather River (NFFR) from Poe Dam downstream to Poe Powerhouse. The North Fork Feather River originates from several small creeks south of Mt. Lassen Peak in northwestern Plumas County and flows through the Upper North Fork Feather River Project No. 2105 and the Rock Creek-Cresta Project No. 1962 prior to being utilized by the Poe Project. Waters of the Poe Project include the Poe Reservoir, a 7.62-mile-long bypassed reach, and the Big Bend Reservoir, which serves as the afterbay for the project. The Poe powerhouse and Big Bend Reservoir are located just upstream of Lake Oroville, the primary storage reservoir for the Feather River Project No. 2100. Water temperature monitoring in the Poe Bypass Reach was completed in 1999, 2000 and 2003, during the relicensing effort for the project. The data collected is included in Appendix E2-3 of the application for the new license for the Poe Project (PG&E 2003). In addition, water temperature has been measured annually in the Poe Bypass Reach from 2003-2018 coincidently with the temperature monitoring required by Condition 4C in the Rock Creek-Cresta Project (FERC No. 1962). However, that data was not included in the annual reports, but will be summarized in the first annual report submitted under this Temperature Plan. 2.0 MONITORING PLAN OBJECTIVES The goal of the water temperature monitoring program is to document temperature in the Poe Bypass Reach following changes in flow rates in accordance with the new FERC license. The temperature data from this monitoring effort will be made available for other biological Appendix A A-4 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report monitoring efforts, such as the Poe Bypass Reach Fish and Benthic Macroinvertebrate Monitoring Plan and the Foothill Yellow-Legged Frog Monitoring Plan. Specific objectives are: 1. Describe seasonal and daily water temperature regimes at multiple locations along the Poe Bypass Reach from April 1 through October 31 of each year of the license, or until deemed necessary by the SWRCB. If safe access to the monitoring sites is not possible by April 1, the temperature monitoring equipment will be installed as soon as it is safe to access the sites. 2. Provide an annual report that includes water temperature and corresponding flows measured in the Poe bypass reach, to the Agency Representatives, following the completion of each annual monitoring campaign. 3. Evaluate the water temperature data no later than 12 years after implementation of the new Canyon Dam flow releases associated with the UNFFR Project to determine if changes in instream flows are needed. 3.0 STUDY AREA AND MONITORING LOCATIONS Water temperature will be monitored at six (6) sites along the North Fork Feather River below Poe Dam. Table 3-1 provides details of each site. Final monitoring sites will be determined in consultation with Forest Service, USFWS, CDFW, SWRCB, Plumas County, and Butte County , using information on proximity to release point, presence of isothermal water column, logistics, and channel morphology. Figure 3-1 depicts the location of the monitoring site and primary tributaries. The monitoring sites are distributed across the bypass reach to capture the influence of accretion flow, project operations and the cumulative distance from Poe Dam. Meteorological data will be collected at Poe Powerhouse including air temperature and relative humidity.

Schematic of Water Temperature Monitoring Site Locations at Poe Project 4.0 METHODS 4.1. Equipment All six (6) sites will be monitored for water temperature using calibrated temperature sensors. They will be deployed annually at all six sites by March 25, or at the earliest date thereafter when access is determined safe due to river flow. Sensors will be retrieved after November 5 each year, unless forecast storms warrant earlier removal due to safe river access. This will ensure that water temperatures are measured during the warmest period of the year. Two temperature sensors will be installed at each site to guard against data loss in the event of equipment failure or drift. The sensors will be deployed in water that is well-mixed, typically at the head of a shallow pool just below a riffle input. Each sensor will be secured in the stream and shielded to assure that the sensor stays submerged and is not exposed to direct sunlight. Appendix A A-7 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report 4.2. Data Collection Water temperature data will be collected at 15-minute intervals and downloaded at least once every two months for the duration of the monitoring period each year. All raw and processed electronic data will be stored in PG&E archives. 4.3. QA/QC Quality control calibrations will be performed on each temperature sensor in a laboratory setting at the end of each monitoring period. The minimum accuracy of all digital recorders is expected to be ± 0.1°C between 5°C and 40°C. A summary of applicable QA/QC certificates will be included with each annual report. Data downloaded in the field from each sensor will be subject to review by PG&E technicians or their contractors. Suspected erroneous data will be identified in annual reports. When temperature sensors are retrieved at the end of each monitoring season, they will be calibrated. Data from sensors that meet calibration requirements will be used in annual reports. The report will also include a list of sensors that failed post-use calibration. Calibration records will be stored in PG&E archives. This review, along with graphical analysis and routine equipment inspection, will ensure that proper data is made available for the annual reports. 5.0 ANALYSIS All data will be summarized to include daily mean, minimum, maximum and maximum weekly average (MWAT) temperatures in degrees Celsius (°C). 6.0 REPORTING 6.1. Annual Reports Study deliverables will include an annual written report covering the Poe Bypass Reach river water temperature monitoring, including average daily flow measured at Gaging Station NF-23. The report will include a description of the sampling locations, methods, QA/QC findings, monitoring results depicted graphically and tabularly, and any problems encountered. Appendix A A-8 April 2022 Poe Project, FERC No. 2107 © 2022, Pacific Gas and Electric Company Poe Hydroelectric Project (FERC Project No. 2107) Water Temperature Monitoring 2021Annual Report PG&E will submit a draft annual water temperature monitoring report to the above named government agencies following the conclusion of each calendar year, covering the resultsof monitoring throughout that year. To establish a consistent template for reporting, prior to submission of the first year report, the format and content of the report will be discussed and agreed to with the government agencies. The first year report will also provide a history of temperature data collected in field studies since 2003. Following the first two years of monitoring, PG&E will submit the draft report to the government agencies on or before March1 of the subsequent year. Following the third year of monitoring, PG&E will attempt to provide the draft report to the agencies before March 1, to allow agencies to make any adjustments to the monitoring plan. PG&E will allow the government agencies at least 30 days to review and comment on the draft report, and will set up a consultation meeting if requested by government agencies. Electronic data (in Excel or comparable format) water temperature and flow data will be provide to government agencies, and to other parties upon request. The final annual report will be filed with FERC by June 30. PG&E will include in the final report any comments and recommendations made by the agencies on the draft report. If PG&E does not adopt a recommendation, t- specific information. 6.2. 3-Year Review As per SWRCB Condition 10, after completion of the first three years of monitoring, theplan will be reviewed by Agency Representatives for possible modifications. To support the 3-year review effort, PG&E will start discussions with Agency Representatives after two years of data are completed to begin assessing if changes to the Plan are anticipated. After the third year of data is collected, PG&E will provide the draft annual report to the government agencies by February 1 (normally it is March 1) such that reviews may begin earlier to determine if changes in monitoring locations are necessary. PG&E will set up a meeting with the government agencies in the month of February to review the draft report and discuss whether changes in monitoring locations or the monitoring plan are necessary. If changes in locations are recommended, PG&E will work with the government agencies, the Deputy Director, and FERC to seek approval to make changes prior to the next monitoring year.

The Temperature Monitoring Plan shall be developed in consultation with Butte County, Plumas County, USFWS, Forest Service, CDFW, and State Water Board staff. The Deputy Director may require modifications as part of any approval. The Licensee sha modifications, with FERC. The Temperature Monitoring Plan shall establish how changes in temperatures as a result of increased instream flows in the Poe bypass reach will be measured. The Temperature Monitoring Plan shall include provisions for possible modification of the monitoring program after the completion of the first three years of monitoring. Where facility modification is required for temperature measurement, the Licensee shall complete such modifications no later than 18 months after license issuance. Ten years after the implementation of new Canyon Dam flow releases associated with the relicensing of the Upper North Fork Feather River Project (FERC Project No. 2105), the Licensee shall consult with Butte County, Plumas County, USFWS, Forest Service, CDFW, and State Water Board staff to evaluate the data collected under the Pro Monitoring Plan and other related information to evaluate whether changes to the instream flows are appropriate. Consultation shall include an evaluation of potential effects related to potential instream flow changes. No later than 12 years following implementation of the new Canyon Dam flow releases, the Licensee shall provide a report on the outcome of the consultation to the Deputy Director that includes: (i) a recommendation regarding whether a change to instream flows is appropriate; (ii) the proposed instream flows, if such changes are recommended; (iii) comments and recommendations made in connection with the consultation; and (iv) a description of how th comments and recommendations. The Deputy Director may require implementation of the recommendation or other alternative deemed appropriate.
