Introduction As the Licensee for the Chignik Hydroelectric Project (FERC Project Number P-620), the City of Chignik is required to annually submit the results of the required monitoring activities. The draft report was submitted to the agencies addressed for a 30 day comment period. The Licensee is required to file with FERC the annual report, along with any agency comments, and how the Licensee plans to accommodate those comments. This report has been revised based on the comments received. This report presents the monitoring data gathered in 2013. This represents the final annual report under the current monitoring requirements. A project operations report is to be subsequently prepared and filed with FERC after consultation with the U.S. Fish and Wildlife Service, NOAA Fisheries, the Alaska Department of Fish and Game and the Alaska Department of Natural Resources in accordance with Article 405 of the License. 1.1 Monitoring Requirements Articles 401 and 402 of the project license require that the licensee conduct fish studies and flow measurements for a period of 5 years, beginning with the 2008 water year and extending City of Chignik - Chignik Hydroelectric, P-620, FERC Compliance 2013 Monitoring Report, Final Draft P-620 2013 Monitoring Report, Rev. 0 Page 3 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. through the 2012 water year. The licensee did not conduct fish surveys in 2010, and proposed extending the five-year monitoring requirement by one year (i.e. until the end of the 2013 water year on September 30, 2013) in order to compensate for this loss of data. FERC approved this extension on October 24, 2011. The required monitoring is described in the Licensee study plan dated October 3, 2006, approved by the Commission on August 22, 2007, and modified by Commission on March 18, 2011 and October 24, 2011. Additionally, the Commission provided 10 specific action items on February 25, 2013 to improve monitoring efforts. The basic monitoring orders are as follows: 1.1.1 Article 401. Stream Flow Gauging and Water Use Monitoring Plan The licensee shall monitor stream flow in Indian Creek downstream of the project’s dam and quantify flow being diverted into the project’s pipeline for a period of five years. The licensee shall, at a minimum, (1) provide for stream gauging of Indian creek; (2) maintain a flow meter and record flows within the project’s pipeline; (3) conduct annual consultation meetings with U.S. Fish and Wildlife Service, NOAA Fisheries, the U.S Geological Survey, the Alaska Department of Fish and Game, and the Alaska Department of Natural Resources; and (4) provide annual stream gauging and pipeline flow reports to each of the agencies identified in item 3 above and to the Commission. 1.1.2 Article 402. Fish Spawning Monitoring Plan The licensee shall monitor fish spawning in Indian Creek for a period of 5 years. At a minimum, the licensee shall: (1) identify species that use Indian Creek for spawning; (2) count the number of spawners by species; (3) identify the location of redd(s) by species; (4) identify the time and duration of spawning activity by species and associated stream flow; (5) conduct annual consultation meetings with U.S. Fish and Wildlife Service, NOAA Fisheries, the Alaska Department of Fish and Game and the Alaska Department of Natural Resources. 2. Indian River Stream Gauging The following analysis and report is for stream gauging activities for 2013. The referenced December 13th, 2013 Stream Gauging and Project Reconnaissance Trip Report (Hatch, 2013) is included as an attachment. 2.1 Overview As part of the monitoring requirements for FERC, monitoring of pipeline flows and gauging of stream flows at the dam, pool, and bridge sites in Indian Creek has been required. Analysis of past stream flow monitoring efforts are found in the annual monitoring reports filed with FERC which are available through the e-library for project P-620. Flow monitoring began in April of 2003 but results over the years have been sporadic because of equipment failures, limited site accessibility, and the general remoteness and harsh conditions at the site.

This report includes an update of stage data, flow rating curves, and discharge calculations for the dam and bridge sites. Consequently, the results that are included in this report supersede previous reports. 2.2 Dam Stream Gauge 2.2.1 Description The existing dam spillway is approximately 10' high1 and impounds Indian Creek creating a reservoir with a surface elevation of approximately 440'2, an area of 21.6 acres3, and an assumed active storage depth of 7'. Outflow from the reservoir occurs via the following mechanisms (in order of occurrence): x Flows through the pipeline to the existing water treatment plant and hydro turbine in the NorQuest facility. Flows through the water treatment plant and existing turbine are assumed equal to amounts granted by water rights. x Flows over the dam spillway, and x Flows through the auxiliary rock cut spillway. Gauging equipment configuration at the dam presently consists of a bubbler type pressure transducer equipped with a data logger that is located upstream of the dam in the reservoir. A staff gauge is also installed in the reservoir. The gauge is a Sutron Accubar constant flow bubble gauge that measures the height of water in the reservoir using compressed air. The gauge was installed on October 17, 2008. Elevation reference monuments for this gauge, shown in the photo below, were presented in the 11/30/2012 Field Activity Report (Polarconsult, 2012) but are revised based on the 12/13/2013 Stream Gauging and Project Reconnaissance trip report (Hatch, 2013). The reference monuments include: x RM#1 elevation = 5.02', an anchor bolt set horizontally in the rock face. x RM#2 elevation = 10.92', an anchor bolt set vertically on a small rock shelf. x Top of staff gauge elevation = 7.32' Photo 1 - Dam Gauge Reference Monuments 1 FERC license application Exhibit F, sheet 9. 2 The crest elevation of the existing dam's spillway is 439.71' based on the average of 4 RTK GPS survey points measured on 5/13/2005 using the DCRA monument HV307, with an established elevation of 231.47', as a datum. 3 FERC Exhibit G lake boundary City of Chignik - Chignik Hydroelectric, P-620, FERC Compliance 2013 Monitoring Report, Final Draft P-620 2013 Monitoring Report, Rev. 0 Page 5 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. 2.2.2 Stage Discharge Curve The stage discharge curve derivation is detailed in the Indian Creek Fish Spawning and Stream Flow Monitoring, Annual Report, Final 2012, Revision 0, October 14, 2013. The same procedure is utilized with the following supplemental information. 1. Past efforts to establish a stage discharge curve were hindered by questionable reservoir stage data associated with flow measurements. This was resolved by performing multiple surveys to establish the dam and rock cut spillway elevations. The results establish an elevation of 2.59' for the dam spillway crest and 2.85' for the rock cut spillway point of zero flow (crest) using the staff gauge as the datum. See the attached December 13, 2013 Stream Gauging and Project Reconnaissance Trip Report (Hatch, 2013). 2. A low flow measurement at the dam was obtained in October 2013 which greatly improves the stage discharge curve. The flow measurement was 19.7 cfs with a corresponding reservoir level of 2.865' (the bubbler reading observed in the field of 2.88' less the 0.015' offset correction). 3. The bubbler data record uses a 0.0 foot offset calibration from installation until 10/8/2009 when an offset of 0.1327' was added to the pressure readings to correspond with the staff gauge datum. This adjustment was made in the field based on a staff gauge observation of 3.51' although wave magnitudes of 0.5' were evident on the staff gauge at the time. On 10/8/13 11:30 AM a staff gauge measurement was made in flat calm conditions that indicated the current offset of 0.1327' should be reduced by 0.015' to 0.1177'. Stage data presented in this report is adjusted appropriately to match the staff gauge datum. Equipment at the dam site is functioning fairly well although ideally the discharge tube from the bubbler would be located as low as possible in the reservoir to catch winter time draw downs. Also, to alleviate the icing correction problem, the bubbler discharge tube would be located such that air bubbles can rise and spread across the entire reservoir surface unimpeded. However, the air pocket accumulation could be alleviated by the lowering the discharge tube to just below the bottom of containment tube or by drilling holes above the discharge tube in the containment tube. Overall, the stage discharge rating curve for the dam spillway is significantly improved. Should stream gauging be continued, the minimum recommended maintenance is to annually perform a level survey and perform low flow discharge measurements, if possible, for the purpose of continued feasibility assessment of hydroelectric resource potential.

It is located close to the end of a riffle section that has a bedrock streambed on the north half of the channel and broken rock and cobbles on the south half of the channel. Stream flow is confined by the bedrock on the north bank and a vertical sheet pile bridge abutment just upstream of the gauging station on the south bank. The station location appears generally adequate and stable with a reasonable stage discharge curve at this time. Ideally the gauge location would be slightly further downstream at a large boulder in a pool section that would also support a staff gauge installation. A vented pressure transducer is installed with the cable routed up the stream bank to a Sutron Monitor 1 data logger mounted to the timber abutment underneath the north side of the road bridge. The data logger is powered by a lithium battery pack. Elevation reference monuments for this gauge, established in the 11/30/2012 Field Activity Report (Polarconsult, 2012), are revised based on the December 13, 2013 Trip Report for Stream Gauging and Project Reconnaissance (Hatch, 2013). The revised elevation monuments include: x RM#1 elevation = 3.23', an anchor bolt used to install gauge located beneath RM#2 x RM#2 elevation = 21.34', the head of a lag set on the bridge structure (shown in photo below).

Pipeline flows Pipeline flows are reported in the December 13, 2013 Trip Report for Stream Gauging and Project Reconnaissance (Hatch, 2013) attached with this report. The dam stage and flow data coincident with the apparent pipeline flow interruptions did not show any change in flow at the dam that could be associated with the pipeline flow. 4. Summary of Stream Gauging Results 4.1 Data Quality Assessment Data quality has been a major concern in the past, particularly at the dam. The area of concern with respect to data quality and accuracy is in the low to moderate flow regions of the stage discharge curve which is important for hydroelectric feasibility and aquatic habitat assessments. The December 13, 2013 Trip Report for Stream Gauging and Project Reconnaissance (Hatch, 2013) resolved several data quality issues as explained below: x The level surveys have generally resolved past errors in establishing the correct water stage, point of zero flow, and reference monument elevations although the two side shot measurements at the bridge site of RM#1 and the 0 flow downstream differ from past surveys and should be verified again in the future if gauging is continued. x The collection of the low flow measurement at the dam filled a large data gap in the stage discharge curve resulting in a significant improvement in data quality. x The relocation of the downstream gauge from the pool site to the bridge site was made because it is thought the bridge site is more stable. Thus far, it does appear to be and has resulted in larger numbers of applicable flow measurements for creating the stage discharge curve. Review of the stage discharge curves above shows the low to moderate flows at the dam site are reasonably well defined with the addition of the single flow measurement of 19.7 cfs although additional low flow measurements would be desirable. Review of the stage discharge curve for the bridge site indicates that there are some potential problems with defining low flows because of the dramatic shape in the curve. This is likely due to the lower flows transitioning from a downstream crest controlled water surface elevation to a cross section/energy loss controlled water surface elevation because the gauge is installed at the tail end of a riffle section. Ideally the gauge should be installed slightly downstream. Two charts are provided in the Appendix that illustrate the correlation of discharge monitoring data. The first shows the entire 2013 water year with discharge plotted on a logarithmic scale while the second shows the discharge at both sites during the fish monitoring period of August through September. Observational differences include: City of Chignik - Chignik Hydroelectric, P-620, FERC Compliance 2013 Monitoring Report, Final Draft P-620 2013 Monitoring Report, Rev. 0 Page 10 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. x The bridge gauge reports slightly higher discharge than the dam gauge at most times. This is generally expected given the larger basin area for the bridge site. x As the discharge drops below around 10 cfs, the ratio of discharge at the dam site versus the bridge site changes with the dam site continuing to drop at a steady rate until spill at the dam ceases versus the bridge site which exhibits a more steady discharge and with flows generally remaining above zero. This may be due to inaccuracies in the low flow region of the stage discharge curve, the withdrawal of water through the pipeline, differing basin characteristics, or a combination of all three. Continued collection of pipeline flow data, relocation of the bubbler to a lower depth, and improvement of the bridge gauge is required to better understand what factors are influencing low flow differences in Indian Creek at the dam versus the bridge. At this time, it is concluded that the stage discharge curve accuracy at both locations has improved significantly from past reports and that the calculated discharge at each gauge site is reasonably accurate at low to moderate flows.

Introduction Daniel Hertrich of Hatch traveled to Chignik Bay to perform stream gauge maintenance, proposed project reconnaissance, and inspection of the existing hydroelectric project and other facilities. The work was conducted in support of the Chignik Hydroelectric Feasibility Study and the FERC required monitoring and infrastructure assessment for project P-620. This report presents the findings of the field investigations relating to stream gauging and proposed project reconnaissance. In 2012 NorQuest Seafoods Inc. (wholly owned by Trident Seafoods) transferred the license for the Chignik Bay Hydroelectric (project), which consists of an aging dam and pipeline that powers a 60 kW turbine. The project’s primary purpose has been to supply potable water for the community and provide base load generation to the former NorQuest facility during the winter months. The project infrastructure is deteriorated and in need of immediate maintenance and repairs. The City desires to evaluate the potential to improve on the utilization of Indian Creek as a hydroelectric resource. The City also requires maintaining operation of the existing project until such time as it is replaced or reconstructed. 2. Logistics Lake Clark Air Services operating out of Merrill Field and Port Alsworth provided passenger service from Anchorage to Chignik and back. Mr. Hertrich flew to Chignik on October 2, 2013 and returned to Anchorage on October 8, 2013. A Leica laser level, tripod, and stadia rod for level surveys was rented from Surveyors exchange. A flouremtric dye tracer and fluorometer stream flow measurement device and other field equipment was provided by Bering Pacific Engineering (owned by Mr. Hertrich). A Hatch owned laptop was used onsite for data collection. Food and equipment totalled 8 pieces of luggage with an approximate weight of 160 pounds. Mr. Hertrich stayed at the City apartment located above the City office during the site visit. Chignik Chignik stream gauge trip report 20131213, Rev.

Access Trail The City has pioneered a road through the quarry that connects the main road, on the south side of Indian Creek, with the existing ATV trail that led to the dam. This is a significant improvement in the ability to access the dam using ATV's or other off road vehicles because it eliminates the Indian Creek crossing, the wetland and Lower Indian Lake stream crossing, and a section of steep gradient rutted trail. The City of Chignik also improved the ATV access trail to the dam by using an excavator to clear vegetation and improve some intermittent stream crossings. The City excavator was then used to carry a load of timbers to the dam. The improvement in access allows an ATV to easily access the dam. A one way trip can now be made in under 20 minutes under dry conditions. The trail is still very basic with the only improvements being clearing and minor grading. The surface primarily consists of overburden which softens and makes travel difficult, if not impassable, when saturated. There are also some very steep grade sections with one a being a challenge for an ATV, particularly when loaded. 4. Proposed Project Reconnaissance The Preliminary Findings Report (Hatch, 2013) provided a map with the proposed penstock route selected based on USGS topography. The field trip included reconnaissance of the proposed route and found that actual topography may not be suitable for construction of the pipeline along the north side of Lower Indian. Of concern is whether the elevation is too high and whether construction equipment could traverse some of the steep gradient sections near the head of the lake and the outlet. Consequently, the feasibility assessment should include a route that follows the existing ATV trail as a consideration.

Pipeline Flows The pipeline flow meter located in the NorQuest processing plant, that also houses the hydro turbine, has a USB data logger attached that records the meter's 4-20 mA loop output. Communicating with the data logger for the purpose of configuring and downloading data required installation of EasyLogUSB software. Data was downloaded on 10/5/2013. It appeared that the power to the flow meter had been turned off on 5/27/2013. Trident was instructed to leave the power to the meter on at all times, as practical, because of the FERC requirements for data collection. The data logger was reinstalled on 10/7/2013 9:30 am. The flow at the time of installation was approximately 200 gpm. The low flow was due to the open bypass valve at the Indian Creek slough. The chart below shows the data that was collected. A table of daily average pipeline flows follows.

Stream Gauging As part of the site visit the stream gauges located at the dam and bridge were downloaded and flow measurements were taken. The desiccant protecting the internal electronics from moisture were also recharged in both gauges and the batteries appeared adequate for continued service. The dam gauge utilizes a solar panel for recharging a lead acid battery while the bridge gauge utilizes a 38 amp-hr lithium ion battery. Because the reservoir was full during the site visit the bubbler tube for the stream gauge at the dam could not be modified to eliminate the occasional ice induced errors that result from air accumulation in the housing tube. Similarly, flashboards could not be installed on the crest to improve low flow resolution. 6.1 Level Surveys Level surveys were performed to verify that stream gauge pressure transducer elevations did not change. The survey was done using a Leica laser level system with rod rented from Surveyors Exchange in Anchorage. The tables below include the raw measurements along with the calculated elevations (all values in feet).
