(AVEC) and NANA Development Corporation (NANA) are evaluating the potential for hydroelectric power generation in the Cosmos Hills region. The objective is to reduce diesel power generation in the communities of Ambler, Shungnak, and Kobuk. Fuel delivery issues, primarily decreasing barge access due to gravel bars and shallow water have caused these villages to have some of the highest power generation costs in Alaska. In 2009, AVEC was awarded a Renewable Energy Grant from the Alaska Energy Authority to evaluate nearby hydropower resources. The project included evaluation of 12 potential hydroelectric sites in the upper Kobuk River valley. Of these, four sites were selected for further evaluation: Cosmos Creek, Wesley Creek, Dahl Creek, and the Kogoluktuk River (Figure 1 ). These sites are appropriately scaled for local energy needs, are close to existing roads and power-line infrastructure, and are run-of-river projects with less environmental impact than large dam-storage hydroelectric projects. With support from NANA, a hydrologic monitoring network was installed to record weather and streamflow data on the three Cosmos Hills streams and the Kogoluktuk River. Although the primary goal of the monitoring network is to evaluate the potential for hydroelectric power generation, the resulting data can also be used for environmental assessments, design of stream and river crossings, and for general water-resource, climate, river-transportation, and weather-forecasting applications. The hydrologic monitoring network includes the following: • Four gauging stations located at the four potential hydroelectric plant intakes; • Four water temperature monitoring stations located in potential tailraces; • Four ridge-top repeaters transmitting data and camera images to an Internet base station at the Kobuk School; 1 • Air temperature, relative humidity, and summer precipitation sensors at the four stream gauging stations; • Time-lapse digital cameras at the four gauging stations and the Upper Kogoluktuk River Winter Supplemental Station; and • Air temperature sensors at the four ridge-top repeater sites.

Some stations decommissioned in Fall 2011. In addition to the four gauging stations at the potential hydroelectric plant intakes, a fifth gauging station was added at the Upper Kogoluktuk River Falls. This station was added in an effort to improve the quality or winter flow measurements. Complex river-ice formation at the Upper Kogoluktuk Station makes winter flows difficult to measure and estimate. The narrow bedrock cross section and confined under-ice winter flows at the supplemental station will make both winter discharge measurements and flow estimation between measurements more reliable. 2 The data-collection procedures used for the project were reported in Lilly and Derry, 2010. The design and installation of the gauging stations and field data-collection approach was intended to help answer the hydropower evaluation questions and start the collection of baseline data that would be required by regulatory agencies under the Federal Energy Regulatory Commission (FERC) process. Both engineering design and environmental assessments require adequate understanding of summer and winter flow conditions and variability between these seasonal extremes. Alaska Department of Natural Resources, Alaska Department of Fish and Game, and multiple Federal regulatory agencies reviewed the project workplan before field work began and indicated the approach would meet their criteria for hydropower-related water-resource investigations. This approach was intended to reduce the potential time required to meet both engineering and environmental evaluations that would be required for project development. Given the high cost of working in remote arctic environments, significant future cost savings and a shorter development timeline would lead to beneficial outcomes for the communities in the region. 1.1 NETWORK /NSTALLA TION OBJECTIVES The installation objectives for the Cosmos Hills Hydrologic Network (Network) in August 2010 included the initial setup of data collection stations, stream surveying, discharge measurements, water chemistry, and general hydrologic observations to start the watershed characterization process. The primary interpretative goal of the project was the development of rating curves for the stage discharge relationship at each of the primary gauging stations. Secondary objectives included basic water-quality characteristics, such as water temperature and conductivity. This information is useful for baseline characterizations, and understanding the processes taking place in each of the surface-water systems, such as groundwater contributions to base flow. Additionally, the region is lacking in background meteorological observations, so the current collection of meteorological data is important to understanding the weather (short-term) and climate (long-term) factors that impact stream conditions and the quality of stage and discharge data. The collection of precipitation (summer rainfall) and 3 snow measurement are particularly important for later hydrologic modeling and flow frequency estimates, as well as permitting and future environmental compliance efforts. 1.2 BACKGROUND HYDROLOGY The study area is located in the interior region of Alaska, on the southern flanks of the Brooks Range, in the Kobuk River watershed. It is in a sub-arctic environment, in the transition zone from continuous to discontinuous permafrost. The lower portions of the drainages are a mixture of forest and tundra, while the upper ridges are primarily bedrock exposures. The Cosmos Hills are bounded on the south by the Kobuk River, on the north and west by the Ambler River and Lowlands, and on the east by the Kogoluktuk River eastern watershed boundary. More detailed descriptions of the watersheds will be provided in subsequent reports. The USGS maintains gauge stations on Dahl Creek (No. 15743850) and on the Kobuk River near Kiana (No. 15744500). Both of these gauges are active and have relatively long periods of record (1986-present for Dahl Creek; 1976-present for the Kobuk River). If results of the present study show good daily flow correlations, it may be possible to generate synthetic streamflow records at the new gauging stations using historic records at one or both of the USGS stations. This practice is termed "record extension" and is commonly used to estimate flood frequency distributions and daily flow statistics. Monthly summer data collection at the Dahl Creek USGS station began in 1986. By 1988 the USGS was reporting data for the whole summer period and by 1990 for the complete water year (October 1 to September 30). The USGS Dahl Creek Station is referred to as the Lower Dahl Creek station for this project, as it is downstream of the other two stations established on Dahl Creek. The timing of flow events from year to year will vary and has a direct impact on planning of field measurements. Figure 2 shows the mean daily mean discharge for Dahl Creek for the period of record. This plot illustrates winter baseflow conditions which are typically are characterized by a slow decline in flow. Spring snowmelt then increases discharge, followed by lower flow conditions in early summer with late summer precipitation floods generally occurring in 4 August. Surface-water flow starts decreasing in September and continues to drop until winter base flow conditions are reached in winter. Figure 3 shows the maximum, mean, and minimum daily mean discharge for the period of record. This helps illustrate the range in flow conditions over the period of record. Note the difference in the scales on they-axis for Figure 2 and Figure 3. The high daily mean flows are highest for early snowmelt floods and late summer flooding with the highest discharge events (flooding) occurring during late summer rainfall events. Timing of the snowmelt flood varies over the period of a month or longer. This time period also illustrates the variability in summer flow conditions that must be taken into account when planning a field measurement program, or hydropower evaluations. The mean and low daily mean discharge characteristics are important for hydropower assessments. Figure 4 shows the mean and minimum daily mean discharge for Dahl Creek USGS gauge for the period of record. It illustrates the range in low flow conditions that can occur during summer months. Figure 5 shows the daily mean discharge for 1999 through 2009 and illustrates the variability in flow conditions over the last 11 years. Note the variability in timing of snowmelt breakup flooding events, which are sensitive to the variability in spring weather conditions. 5 140 USGS 157 43850 Dahl Creek Gauge Near Kobuk ~ 120 u c -_ 100 ()) ~ ro -5 80 (/) ~fi 0 c ro 60 ~ >. ~ 40 0 c 20 ro ~ ' \ -~ ~, \ ... ,~ ' \ r ,I'--......_ 0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Period of Record Figure 2.

The extent of the benefit from this station is dependent on the collection of supporting data to help develop correlations with climate and hydrologic processes. The gauge has a potential for serving as an index station for water-use permitting and hydropower design. lnstream water reservations for permitting normally require 4-5 years of data collection. Correlation between the USGS gauging site and stations in the hydrologic monitoring network may result in a shorter data collection period for permit applications, depending on the correlations between surface-water systems. Collection of comparative surface-water and meteorological data sets are critical for environmental and engineering evaluations. 2.0 PROCEDURES The following sections describe the general procedures used during the reporting period. As continued data collection activities are conducted, these procedures may be changed to help meet current or future project objectives. 2.1 SITE SELECTION The general site locations for the upper gauging stations in each of the study watersheds were determined during preliminary hydropower assessments performed by WH Pacific (201 0). General locations of the plant intakes were identified, and then gauging sites were selected that were at, or slightly upstream of, the location where flow conditions appeared conducive for continuous stage measurements. The stability of channel conditions and general site access was also taken into account for each station. Downstream station locations were selected based on the location of potential outlet structures for each hydropower plant. Water temperature was measured at, or slightly downstream of, each intended discharge location from the planned hydropower plants. The temperature data will be used to evaluate the baseline temperature gradients in the streams during the anticipated hydropower-production season. Basic hydrology observations will also be collected during station visits. 8 2.2 GAUGING STATION INSTALLATION AND OBJECTIVES The data stations are solar and battery powered. Land use permitting applications and associated documentation were prepared for AVEC and coordinated with their permitting contractors. The data-collection platforms use Campbell Scientific equipment, which is the standard used in a majority of the North Slope and western Alaska hydrologic and climate networks. The primary data collection at each station is stream stage, with supporting data collection including water temperature, air temperature, relative humidity, and summer precipitation (unshielded). Early spring station visits will be used to measure end-of-season snow conditions. The winter snowpack conditions are important for both understanding the snowmelt flood hydrograph and summer base flow conditions. There are currently no known snow measurements taking place in the Cosmos Hills region. Remote reporting of data provides cost savings in several areas, primarily in supporting field logistics. Benefits are also gained by reducing data loss caused by animals, flooding and other environmental factors. The station construction allowed operations through winter and summer seasons, withstanding animal or other environmental damage. A test of the station construction methods occurred in February 2011, when an avalanche covered up the Upper Cosmos Station. The station continued to collect stream water level and temperature data through the rest of the winter and during spring snowmelt flooding at the avalanche area, even when most of the station was under water. Real-time data reporting will also help support other logistical efforts in the area and local communities. A base station is located at the local school in Kobuk, with radio repeaters located on high ridges to allow communication to the gauging stations located in stream and river drainages. Field work in the project area is costly due to its remoteness and difficult logistics. The Kobuk area is nearly two hours away from Fairbanks or over an hour away from Kotzebue in a small plane. At least two of the gauging stations require helicopter access (Cosmos Creek, Kogoluktuk River). Stations were accessed by field crews via helicopters, ATVs, snowmachines or on foot. Over four hundred pounds of cabling, 9 conduit, batteries, photovoltaic panels and cameras were required at each station. Most of the field stations were accessed by helicopter in the summer and by snow machine in the winter. During the summer season, hydrologists were sheltered in huts at the Dahl Creek camp. In the fall, winter and spring seasons, floor space at the school in the village of Kobuk was utilized and had to be periodically vacated to accommodate school sessions. Due to poor weather, there were times during field visits when the helicopter was unable to fly and workers were on standby waiting to fly out to the sites. All of these factors contributed to the expense of the remote hydrology fieldwork. The data collection objectives at each of the primary gauging stations includes parameters to measure surface-water stage, unshielded precipitation, bank temperatures, shielded air temperature and relative humidity, and station diagnostics. Detailed descriptions of the data collection parameters are available in Appendix G and H for an example station. Each station uses the same data collection standards. The only exception is that one station (Upper Cosmos Creek Station-discontinued) also measures barometric pressure (NOT adjusted to sea level elevation for aviation applications). Barometric pressure is generally a regional property and cost considerations supported only one station having this measurement. Additionally, the surface-water gauging stations include cameras to help record visual observations of stream conditions, important for the general understanding of stream conditions, snow and winter icing conditions, and support of transportation logistics. Additional data for the sensor specifications and other station information is available on the project website. There are also repeater stations, used to help transmit data from the surface-water stations (normally in low-lying areas) back to a base station in Kobuk. The repeater stations also record shielded air-temperature and station diagnostics. The primary data reporting period is during summer months. Station data is normally updated every 1 to 3 hours. Adverse weather, animal damage (bears, foxes, etc.) and other environmental factors may impact station reporting. The Campbell data loggers provide 150 or more 10 days of onsite storage so no information is lost during periods when the telemetry network is not functioning. 2.3 LEVATION SURVEYING AND WATER LEVEL MEASURMENTS Local survey control, temporary benchmarks (TBM's), and stream cross sections were surveyed each field trip. The TBM's were established during the station installations in August 2010. Depending on ground conditions, benchmarks (generally rebar or bolts in stream boulders) may move on a seasonal basis, so a set of three to five benchmarks were installed at each site. TBM's were established to provide multiple balanced shots to help track potential seasonal movement of TBMs and make any required elevation adjustment. Reference marks (RMs) were also established to primarily provide easy measuring points for surface-water elevations at varying stage levels. Closed loop surveying was used to measure any changes in TBMs and RMs during each station visit in spring and summer months (Kennedy, 1990). Elevation-survey measurement forms are included in Appendix A. Water-level measurements and adjusted gauge heights made during the field trips in August and October 2010 and May, August, September, and October 2011 are reported in Appendix B. It is important to characterize stream cross-sections for establishing stream gauging stations and rating curves. During the August 2010 field trip, cross-section surveys were conducted at the Cosmos Creek, Dahl Creek, Wesley Creek, and Kogoluktuk River Stations and during the August 2011 field trip a cross-section survey was conducted at the Upper Kogoluktuk River Station. This data is reported in Appendix C. Cross-section surveys include surveys perpendicular to the channel and surveys upstream and downstream of the station to establish the water slope. Subsequent cross-section surveys may be made as needed when signs of erosion or other changes are noted during field visits. 2.4 WATER CHEMISTRY MEASUREMENTS The general water-quality measurements made for this project include temperature and conductivity. Appendix D reports the basic water-quality data measured at various creek 11 and river locations. The supporting water-quality meter calibration forms and resulting quality assurance results are provided in Appendix E. Additionally the station data collection systems measure and store water temperature information from the pressure transducers and stream-bank thermistors. The downstream sites located near the proposed hydropower outfalls use Hobo instream data loggers that measure stream temperature. The Hobo sensors have to be manually downloaded during station visits, or sensors are swapped with replacement sensors and downloaded at a later time. This data is reported in Appendix M. 2.5 DISCHARGE MEASUREMENTS Discharge measurements were performed using an acoustic doppler current profiler (ADCP) and by conventional current meter methods. These techniques are described in the following sections. 2.5.1 ACOUSTIC DOPPLER DISCHARGE MEASUREMENTS Except for a low-flow measurement on October 15, 2010, all of the discharge measurements on the Kogoluktuk River were performed using either a 2.0 kHz StreamPro or a 3.0 kHz Sontek RiverCat ADCP. Both of these devices are designed for shallow-water operation, with a maximum depth range of about 17 feet. The ADCP integrates water depths and velocities along transects extending from bank to bank, and computes a total discharge for each transect. Measurement of multiple transects improves the accuracy of each measurement and allows evaluation of overall measurement precision. Whereas Sontek's data acquisition software accepts both bottom-track and GPS positioning, the Stream Pro software accepts only bottom-track positioning. For the Sontek ADCP, a Geneq differential GPS (OGPS) receiver was used to collect position information via the Federal Aviation Administration's Wide Area Augmentation System (WAAS). Poor satellite reception prevented accurate WAAS positioning during the August 2010 trip therefore ADCP measurements relied solely on bottom-track positioning, however the clear water and shallow depth of each transect (less than 4.5 12 feet) permitted visual observation of the sand to cobble-sized bed material. No bed movement was observed (nor is expected) based on the water velocities and bed materials encountered. The Sontek ADCP was not available for the May 2011 measuring event. As a result, the StreamPro was used, and each discharge measurement was accompanied by a loop moving bed test. Although the StreamPro provided acceptable results on May 28 and May 30, higher flows on May 23 and May 25, 2011 resulted in signal loss due to excessive turbidity and/or bed motion. As a result, the May 23 and May 25 discharge measurements were not usable. In the future, GPS positioning could help reduce ADCP data loss during spring breakup flow measurements. Upon completion of the ADCP measurements, the data were reviewed for internal consistency and acceptable precision measures. A subsequent office review included the following: • Reprocessing of each transect to confirm that the proper edge distances, transducer depths, and stream temperatures were used; • Review of each transect to identify lost or invalid ensembles; • Review of ship tracks and velocity vectors to identify bottom-track positioning problems; • Moving bed test processing and corrections; and • Comparison of multiple transects to evaluate precision. 2.5.2 CURRENT METER DISCHARGE MEASUREMENTS Following procedures outlined by Rantz, et al., (1982), discharge measurements on Cosmos Creek, Wesley Creek, and Dahl Creek were made using conventional current meter methods. A surveyor's tape was used to divide the stream width into at least 25 partial vertical sections (termed "verticals"). The widths of the verticals were spaced such that no vertical contained more than 10 percent of the total discharge. For depths less than 2.5 feet, the velocity was measured at 60 percent of the water column height, and for depths over 2.5 feet the velocity was measured at 20 and 80 percent of the water column height. The velocity measurements were made with a Marsh-McBirney 13 Flow Mate 2000 flow meter mounted on a top-setting wading rod. Water depths were recorded to the nearest 0.05 feet. 2.6 SNOW SURVEY MEASUREMENTS Snow is an important part of the hydrologic cycle in the Cosmos Hills. Very few if any historical snow measurements exist. The development of baseline snow conditions began in March 2011, with the first spring snow surveys made for this project. Snow surveys are conducted by selecting sites that will help define the regional snow distribution. These would include sites in forested, tundra, and open environments. A typical site involves performing a snow-course, which includes collecting snow depth as well as snow density, using a method sometimes referred to as "double sampling". Snow-course data collected for the Cosmos Hills Hydrologic Project follows procedures as described by Derry, et al., 2009. Snow-depth measurements are performed in "L" shaped patterns with aT-handle probe approximately every 3.3 ft (1 m) for 82ft (25m), then turning 90 degrees, and continuing for another 82ft (25 m). Five snow density samples are collected with an Adirondack snow sampler at each site. To calculate average snow water equivalent (SWE) for a snow-course, the average of 50 snow depths are multiplied by the average of 5 snow density samples. The heterogeneous Arctic snowpack is more variable in depth than in density (Benson and Sturm, 1993); hence, more depth-measurement locations are required relative to density- measurement locations. 14 3.0 SITE DESCRIPTIONS This section describes the locations and general characteristics of each of the stations in the network.

The primary goal of this project is to develop rating curves for gauging stations installed on the four streams selected for hydropower evaluations. Improved rating curves and more detailed interpretations will be possible after completion of the 2012 field season. Additional data is available on the project website (www.cosmoshydro.org), and appendices following the text of this report provide a summary of manual measurements collected during the field program. 4.1 DISCHARGE MEASUREMENTS The following section summarizes results for discharge measurements performed using conventional current meter and acoustic Doppler measurement methods. Salt dilution methods were also attempted on Dahl and Cosmos Creeks, but better precision was obtained using current meter methods (see below). Flow conditions were adequate for current meter measurements on each of the small creeks, and during low-flow conditions (October 201 0) on the Kogoluktuk River. The August 2010 and October 2010 discharge measurements on the Kogoluktuk River were performed at the location shown on Figure 16. Due to the presence of shore ice in the vicinity of the gauge, the October 2010 stage measurements on Cosmos Creek and the Kogoluktuk River could have been ice-affected and were not used. High-flow ADCP measurements on May 23 and May 25, 2011 could not be used due to excessive signal loss, subsequent ADCP measurements on May 28 and May 30 yielded acceptable precision values (2.0 to 2.9 percent). A summary of discharge measurements is shown in Table 2, indicating that the average precision of current meter measurements was 1.7 percent, and the average precision of ADCP measurements was 3.0 percent. All of the current meter measurements satisfied the USGS criterion of no more than 10 percent of the total discharge within any partial vertical section. 26 Figure 16. 2010 Discharge measurement locations, Kogoluktuk River. Comparison of ADCP discharge values based on bottom-track vs. GPS positioning indicate that moving bed conditions occurred only during spring breakup on the Kogoluktuk River. Correction of bottom-track discharge measurements using the loop moving bed test (Mueller and Wagner 2009) yielded reasonable moving bed velocities (0.15-0.2 Ws) and acceptable precision values(< 2.9 percent). 27 Table 2.

The following sections describe the correction of pressure transducer data, rating curve development, and computation of daily streamflows. 28 4.2.1 CORRECTION OF PRESSURE TRANSDUCER OAT A Pressure transducer readings are converted to stream stage by adding an "offset" so that the sum of the transducer reading and the offset equals the surveyed water surface elevation. If the pressure transducer is moved, the offset is changed so that the calculated stage equals the surveyed water surface elevation. Similarly, the effect of transducer "drift" can be removed by changing the offset values so that the calculated stage equals the surveyed water surface elevation. These corrections were performed using the Aquarius Workstation, a commercial software package designed for streamflow computations. Aquarius data files for each gauging station are archived with project records. These files contain a record of all of the corrections performed on each data set. The following sections summarize corrections performed on transducer data from each gauging station. 29 Upper Dahl Creek Station. Figure 17 shows the raw and corrected stage data for the Upper Dahl Creek Station. The corrected data is initially based on pressure transducer no. 1 (PT1), but switches to PT2 on October 17,2010. The PT2 record is fairly "clean", requiring only a minor drift correction during the summer of 2010. Several pressure spikes were removed during the winter months, which are assumed to reflect ice formation on the transducers. 93 Q) 92 ~ .... ..r:. Cl "Q) ..r:.

Raw and corrected stage data for the Upper Wesley Creek Station. 31 Upper Cosmos Creek Station. Camera images, transducer records, and field visits indicate that the Cosmos Creek gauge height was ice-affected from about October 1, 2010 until May 2011. In addition, the gauging section was struck by an avalanche on February 23, 2011, resulting in temporary damming until a flow conduit melted through the avalanche debris. Upon the first field visit in May 2011, overflow channels were melted in the avalanche debris, indicating that breakup gauge heights were affected by snow damming. The stage hydrographs for Dahl and Wesley Creeks both exhibit smooth recession curves from September 2010 through May 2011 (Figures 16 and 17). Although the stage record for Cosmos Creek was affected by ice cover and avalanches, it is reasonable to assume that the flow hydrograph should show a similar recession . As a tool to estimate winter flows, a synthetic winter stage hydrograph was drawn mimicking those for Dahl and Wesley Creeks (Figure 19). The synthetic winter stage record has no physical significance other than as a tool to estimate winter flows. 100 -Transducer no . 1 -Transducer no. 2 99 -Corrected stage 0 Hand measurement -Q) ~ 98 -..c.

Raw and corrected stage data for the Upper Cosmos Creek Station. 32 No attempt was made to estimate the breakup stage hydrograph for Cosmos Creek. Due to its larger basin area, breakup flows were probably higher than those for Wesley and Dahl Creeks. However, there is no way to eliminate the effect of snow damming caused by avalanche debris on the breakup stage record. The corrected stage data for Cosmos Creek is based on records from PT1, which was replaced by PT2 after the 2011 breakup. Aside from the synthetic winter hydrograph and the missing breakup hydrograph, only minor drift corrections were applied to the 2011 stage record. Upper Kogoluktuk River Station. Camera images, transducer records, and field visits indicate that the Kogoluktuk River gauge height was ice-affected from about October 1, 2010 until late May 2011. During the first field visit on May 23, 2011, stranded ice blocks indicated that the breakup stage hydrograph was probably affected by ice jamming. Like the stage hydrographs for Dahl and Wesley Creeks, the mean daily discharge hydrograph for the Kobuk River near Kiana (USGS Station No. 15744500) shows a smooth recession curve from October through May of the following year. Although the stage record for the Kogoluktuk River was affected by ice, it is reasonable to assume that the flow hydrograph exhibits a similar recession. As a tool to estimate winter flows, a synthetic winter stage hydrograph was drawn mimicking those for Dahl and Wesley Creeks (Figure 20). 33 -Transducer no . 1 -Transducer no . 2 -Corrected stage 0 Hand measurement 82 ~~r-~-,--~~--~~--~~--~~--~~--~-r--.--.-. 7/12/10 9/11/10 11/10/10 1110/11 3112/11 5/12/11 7/12/11 9/10/11 11/10/11 1/10/12 Figure 20. Raw and corrected stage data for the Upper Kogoluktuk River Station. No attempt was made to estimate the breakup stage hydrograph for the Kogoluktuk River. Without flow measurements, there is no way to eliminate the effect of ice jams on the stage record during breakup. The corrected stage data for the Kogoluktuk River is based on records from PT1, which was replaced after the 2011 breakup. In addition to the synthetic winter hydrograph and the missing breakup hydrograph, several offset and drift corrections were applied to the 2011 stage record. 34 4.2.2 PRELIMINARY RATING CURVE DEVELOPMENT Rating curves were developed for each station to allow computation of discharge from corrected stage records. Assuming steady and uniform flow, the rating equation can be developed from Manning's equation for open-channel flow: Q=C(G-el where: Q =discharge, C =a coefficient mainly controlled by channel width and bed roughness, G = gauge height, e = an offset that relates gauge height to hydraulic head, and a= an exponent mainly controlled by channel geometry. With field measurements of Q and G, the rating equation contains three unknowns, which require solution by numerical optimization. Without constraints on the realistic ranges of C, e, and a, an equally-good fit of Q and G can be obtained for a wide variety of parameter values. Within the range of measurement, inaccurate parameter values may have only a minor effect on the overall goodness-of-fit. However, when the rating equation is extrapolated to high and low flows, unrealistic parameter values can result in significant computation errors. Although no low flow measurements have been performed, low flow estimates are needed to prioritize further field work. These estimates were developed by rating curve extrapolation, using care to ensure that parameter values were within reasonable limits. With choice of the correct gauge offset (e), measurements of flow vs. (G -e) should plot as a straight line in bilogarithmic space. The gauge offset is further constrained by the elevation of zero flow, which should approach the lowest gauge offset. If there is a breakpoint in the rating, the gauge offset should be larger at higher flows. The exponentDa varies between about 1.3 and 3.0, depending on the shape and length of the control. The exponent is typically lower for rectangular than for v-shaped 35 channels, and should increase with channel complexity. Higher exponents can also result from failure to conform to the steady, uniform flow assumption. The coefficient C carries information regarding the slope, roughness, and channel complexity. V-shaped channels should have larger coefficients than rectangular channels. With realistic values for a and e, C can be determined by curve-fitting. The following sections discuss the rating curves obtained for each gauging station. Upper Dahl Creek Station. A preliminary rating for the Upper Dahl Creek Station is illustrated in Figure 21, based on eight flow measurements ranging from 16.4 to 103 cfs. One flow measurement on August 12, 2010 was not honored, possibly due to unsteady flow conditions resulting from heavy rain. A gauge offset of 89.81 feet results in a linear plot in bilogarithmic space, and is consistent with the elevation of the downstream control. The rating exponent (2.824) is also consistent with a laterally confined, bouldery control. Extrapolation of the rating curve to the highest and lowest gauge heights results in maximum and minimum instantaneous flows of 290 and 2.1 cfs, respectively. The maximum and minimum mean daily flows are 209 and 2.2 cfs, respectively, which show reasonable agreement with the maximum and minimum mean daily flows for the Lower Dahl Creek Station (224 and 2.5 cfs; USGS No. 15743850). Except for some short pressure spikes, the 2011 winter gauge record at the Upper Dahl Creek Station does not require correction for ice effects, as is necessary at the Lower Dahl Creek station (USGS No. 15743850). This is probably due to the relatively confined cross section at the upper Dahl Creek gauge pool (Figure 22). 36 92.5 92.0 Q) 2 91.5 91.0 90.5 I I Single measurement or average 0 of replicates (error bars indicate standard deviation) L:::.

Upper Wesley Creek Station. A preliminary rating for the Upper Wesley Creek Station is illustrated in Figure 23, based on ten flow measurements ranging from 9 .5 to 79 cfs . A gauge offset of 90.97 feet results in a linear plot in bilogarithmic space, but yields unrealistically low flows(< 0.1 cfs) at the lowest observed gauge height (90.95 feet on May 12, 2011 ). Camera images suggest flows on the order of 1-2 cfs during this timeframe, which is consistent with the ratio of annual minimum to October 15th flows on nearby measured streams (Figure 24). As a result, a breakpoint was added and a smaller exponent was used to obtain higher minimum flows. 38 93.2 92.8 92.4 a; ~ 1: Cl "iii 92.0 .c.

Extrapolation of the rating curve to the highest and lowest gauge heights results in maximum and minimum instantaneous flows of 590 and 1.4 cfs, respectively , and a maximum mean daily flow of 237 cfs. Although the maximum instantaneous flow is higher than that for upper Dahl Creek (290 cfs), the mean annual flow for upper Wesley Creek is 70 percent of that for upper Dahl Creek. This compares favorably with the ratio of basin areas (67 percent). The lower peak flow for upper Dahl Creek may be related to the elongated shape of the Dahl Creek watershed as compared with the Wesley Creek drainage basin.

A preliminary rating for the Upper Cosmos Creek Station is illustrated in Figure 26, based on seven flow measurements ranging from 31.7 to 131 cfs. One flow measurement on October 14, 2010 was not honored due to ice effects. A gauge offset of 90.97 feet results in a linear plot in bilogarithmic space, but yields unrealistically high flows at low gauge heights, even when October 2010 ice effects are removed (Figure 19). As a result, a breakpoint was added and a smaller offset applied to gauge heights below 96.8 feet. a; $ :i Cl ·a; .r::.

Surveyed cross section at the Upper Cosmos Creek Station. 80 Although no data supports the lower rating curve segment, the gauge offset (96.14 feet) and the rating exponent (2.296) for the upper segment are consistent with the control geometry (Figure 27). Extrapolation of the rating curve to the lowest synthetic gauge height results in flows consistent with the ratio of annual minimum to October 15 flows on nearby measured streams (Figure 24). The rating curve was not extrapolated to the highest gauge heights due to snow damming caused by avalanche debris. Upper Kogoluktuk River Station. A preliminary rating for the Upper Kogoluktuk River Station is illustrated in Figure 28 , based on six flow measurements ranging from 921 to 5,614 cfs . One flow measurement on October 15, 2010 was not honored due to ice effects. A gauge offset of 82.60 feet results in a linear plot in bilogarithmic space , and 42 both the gauge offset and the rating exponent (2.568) are consistent with the complex channel cross-section (Figure 29). To obtain annual minimum flows consistent with Figure 24, a breakpoint was added and a smaller offset applied to gauge heights below 84.54 feet. Parameter values for the lower segment have little meaning because stage hydrograph is synthetic below the assumed breakpoint. Extrapolation of the rating curve to the lowest synthetic gauge height results in flows consistent with the ratio of annual minimum to October 15 1h flows on nearby measured streams (Figure 24). The rating curve was not extrapolated to the highest gauge heights because they probably reflect ice jams during spring breakup. 90.0 Average ADCP measurement 88.0 E Cl ~ 86.0 /::,.

Surveyed cross section at the Upper Kogoluktuk River Station. 4.2.3 MEAN DAILY FLOW COMPUTATIONS Mean daily flows were computed with the Aquarius Workstation using the rating curves and corrected stage records described above. Mean daily flows are tabulated in Appendix L, and the corresponding hydrographs are shown in Figure 30. 4.2.4 STREAMFLOW MEASUREMENT DISCUSSION In contrast with the U.S. Geological Survey's Lower Dahl Creek Station (no. 15743850), winter stage hydrographs at the upper Dahl and upper Wesley Creek stations exhibited only brief pressure spikes during periods of extreme cold. Upon return to more moderate winter temperatures, both stage hydrographs reverted to a gradual recession curve (Figure 30). This behavior is interpreted as pressurized flow beneath ice cover 44 during cold snaps, followed by open-water conditions beneath ice cover as the stream stage continues to decline. Based on the stage hydrographs, it appears that the wetted perimeter beneath ice cover was largely ice-free, allowing extrapolation of the rating curves to winter low-flow conditions. Although 2011 winter flows for the Kobuk River at Kiana (USGS Station no. 15744500) are estimated at a constant 1 ,500 cfs from February 10 to May 7, the 31-year mean flow shows a smooth recession curve matching those for Dahl and Wesley Creeks (Figure 30). This suggests a regional relationship that may be applicable to other streams. Although no winter flow measurements are available to confirm them, winter flows for Cosmos Creek and the Kogoluktuk River were estimated by mimicking the recession curves for Dahl Creek, Wesley Creek, and the 31-year record on the Kobuk River. Specifically, annual minimum flows for Cosmos Creek and the Kogoluktuk River were estimated at 14 percent of flow on the preceding October 151h, which represents the average value for the Kobuk River record. Inspection of the resulting hydrographs suggests that the Kogoluktuk's actual minimum flow might be higher than the resulting 50 cfs, perhaps due to unusually low flows on October 15, 2010. Additional high-flow measurements will be needed to confirm the estimated peak flow for Wesley Creek (590 cfs), provided that the Upper Wesley Creek Station rating remains stable. The estimated peak flow for upper Dahl Creek (290 cfs) agrees with daily flows for the Lower Dahl Creek USGS station (no. 15743850). Estimated peak flows were not obtained for Cosmos Creek and the Kogoluktuk River, where the stage records were affected by ice jams and avalanche debris. Although the upper Cosmos and upper Dahl Creek stations have been decommissioned, winter low-flow measurements are needed to confirm the rating curve on Wesley Creek, and the recession curve for the Kogoluktuk River. If ice cover prevents open-water discharge measurements, salt dilution could be used on Wesley Creek, and dye dilution could be used at the Upper Kogoluktuk Supplemental Station. 45 Both techniques require thorough mixing, which would be possible at the Upper Kogoluktuk Falls and in the rapid above the Upper Wesley Creek Station. If peak flow measurements are needed for the Kogoluktuk River, these will require direct ADCP measurements using GPS positioning. With ADCP measurements on both limbs of the breakup hydrograph, it should be possible to estimate the peak flow if ice prevents direct measurement. 1000000 100000 ~ 10000 ai E' m .t:. u "' i5 1000 :?: "ffi c c:: m ~ 100 10 ----UpperDahiCk ----Upper Wesley Ck ----Upper Cosmos Ck ----Upper Kogoluktuk R ----Kobuk River 2011 ----Kobuk 31-year mean ~ ..........

Mean Daily Hydrographs. 4.3 WATER TEMPERATURE MEASUREMENTS Understanding baseline water temperature conditions is important for evaluating any type of hydropower development. 4.3.1 WATER TEMPERATURE RESULTS We measured water temperature at the primary gauging sites and locations downstream in each of the three creeks and the Kogoluktuk River. The locations are at the approximate discharge points for early designs of the hydropower infrastructure. 46 Examples of stream temperature data for the lower stations (Figure 31 ), upper stations (Figure 32), and the Upper Kogoluktuk River Station (Figure 33) follow. The Kogoluktuk River temperatures are warmer than the three creeks until the onset of winter. In early winter, the temperature relationship is changed and the Kogoluktuk River water temperatures are colder at the downstream station. This change in temperature relationship is likely due to the differences in groundwater inflow to the streams, versus the upstream surface-water exposure to atmospheric warming. The drop in the temperature below freezing at the Lower Kogoluktuk River Station in October may be related to short-term freezing of the sensor in river ice. The data also shows the sensitivity of the surface-water systems to diurnal temperature warming. The summer temperatures are more similar between Cosmos Creek and Wesley Creek, with Dahl Creek generally having colder temperature conditions. 47 20 18 16 0 14 0 c 12 Q) 5 10 -cu ... 8 Q) Cl.

In the lower slopes of the Cosmos Hills and the North-South transect up Wesley Creek and Ruby Creek, the snow conditions were fairly uniform. The snow conditions at the upper ridges were noted to be more wind packed and have thinner snow cover. The average density at seven snow-course sites (Table 3) during the March field trip ranged from 0.22-0.26 g/cm3 , which indicate very homogenous snowpack conditions. Due to this consistency in density, as well as traveling and sampling time constraints, at three sites (Kogoluktuk River-Forest, Wesley Creek-SC1 , and Wesley Cree k-SC5) only snow-depth measurements were collected in order to ensure adequate time to collect a greater spatial coverage of snow depth. SWE was 50 calculated for the three sites where density was not collected by taking the average density from nearby representative (in terms of general landscape and vegetation type) snow-course sites. The SWE ranged from 6.4 inches H20 (16.2 em) to 12.8 inches H20 (32.6 em) with an area average of 10.1 inches H20 (25. 7 em). The average snow depth for the study area was 43.0 inches (1 09.2 em). The average density for all sites sampled was 0.23 g/cm3 . Discussions with local residents and teachers of Kobuk indicated this was a relatively high snow year, compared to at least the last ten years.

The primary purpose of the network and resulting field data collection efforts is to establish stage-discharge rating curves for each of the surface water systems of interest. Secondary objectives include the collection of surface-water temperature data at the main gauging stations and downstream stations located near potential hydropower outlets. Summer precipitation and spring snowpack measurements are also measured, along with air temperature and relative humidity. Surveying, manual water quality measurements and other general field hydrology observations were also recorded for the data stations and surface-water systems. The data station network includes repeater sites to help provide telemetry communications back to a base station located at Kobuk School. Selected data is reported on a project website. Additional surface-water discharge measurements were made in October 2010 to help establish discharge observations at low water conditions. Cosmos Creek and the Kogoluktuk River October discharge measurements were ice affected and are likely not applicable to the rating curve development, but still useful for understanding the early winter flow conditions at the respective stations. During severe winter storms in February 2011, three of the repeater station radios were impacted by potential atmospheric static conditions. These radios were repaired during the spring 2011 field efforts. Snow surveys and station visits were made near the end of March 2011. Warm conditions and deep snowpack resulted in field crews not being able to access the Upper Cosmos Creek Station and the Upper Kogoluktuk River Station. Upper Wesley Creek and upper Dahl Creek stations were visited and station operations were normal and data collection systems were working well. Snowpack conditions are high for spring 2011. Depending on spring weather conditions, this should result in relatively high snowmelt discharge conditions. An evaluation of the hydropower potential allowed the 53 evaluation of the four main stations and it was determined that Wesley Creek and the Kogoluktuk River hydrology data collection efforts should continue. A winter supplemental gauging station was established on the Kogoluktuk River to help provide winter flow information and establish a location to conduct winter flow measurement. All of the project objectives were met during the period of August 2010 through December 2011, with the exception of the impacts of the February storm event on the telemetry reporting system. 6.0 REFERENCES Benson, C.

STATION MET ADAT A STANDARDS EXAMPLE The following Kogoluktuk River Station Metadata Standards example represents the standards used at each site. G-1 Cosmos Hills Hydro-Electric Hydrologic Network Project Upper Kogoluktuk River Stream Station Data Measurement and Recording Standards Last Update: 09/20/10 Last Update By: AMcHugh Stream Station Data-Collection Objectives: Meteorological and hydrologic data to evaluate the potential for hydro-electric power generation in the Cosmos Hills region. Time Recording Standard: Always Alaska Standard Time (UTC -9). Datalogger Scan Interval Standard: 60 seconds. Time Measurement Standards: Hourly readings are recorded at the end of the hour; therefore, the hourly average water temperature, for example, with a 60-second scan interval and a time stamp of 14:00 is measured from 13:0 I to 14:00:00. For a 60-second scan interval, the hourly average would be the average of 60 min = 60 values. Quarter-hourly readings are recorded every fifteen minutes starting at the top of the hour. Instantaneous readings are taken at the time specified by the time stamp. A day begins at midnight (00:00:00) and ends at midnight (23:59:55). All daily data are from the day prior to the date of the time stamp. For example, ifthe time stamp reads 09/09/2007 00:00 or 09/09/2007 I2:00:00 AM, the data are from 09/08/2007.

STATION METADATA STANDARDS QAQC The following metadata quality assurance and quality control (QAQC) standards are designed to illustrate the steps involved in QAQC analysis of data retrieved from data stations. 1-1 •!• Data. QA/QC STANDARDS FOR DATA-COLLECTION STATIONS Data is obtained from the diagnostics web page for the project. o Alternatively, data can be obtained from the station directly using LoggerNet. •!• Original Data files. o Each station has an Original Data file in Excel. o The data found in this file is the original data retrieved from the datalogger. Each output table appears on a separate tab in the Original Data Excel file. •:• QA Process Data files: Each station has a QA Process Data file for each output table. o The data in these files undergoes the QA process and individual data points may be corrected or deleted if there is a problem. Data in these files is then deleted when moved to its Final Data file, usually once per year. •!• Final Data files. o Each station has a Final Data file in Excel. The data in these files have undergone QA and any problems with it have been resolved. Each output table appears on a separate tab in the Final Data Excel file. •!• Monthly QA Calculation files: o Each station has a Monthly QA Calculation file for each month beginning with the first month of station operation. o These files are used to check for completeness of records and out-of-range data, as well as to create summaries of selected data. •!• Monthly Quality Reporting Summary files. o The project has a Monthly Quality Reporting Summary file which is a concise summary of all of the Monthly QA Calculation files for all of the stations in the project. •!• QA Graphs files. c Each station has a QA Graph file. c The critical data from a station has been plotted in its QA Graph file. The plots are used to identify problematic data. Each graph is saved in .wmf format. If original data in the file are changed during the QA process (e.g. spikes are removed from the data set), the graph of the original data is saved in .jpg format. The corrected data is then saved in .wmf format. The plot of the original data would contain a note on the graph indicating that it is original data before the QA process. The plot of the corrected data would contain a note on the graph indication that it is corrected data after the QA process. 1-2 •!• QA Actions and Notes files. o Each station has a QA Actions and Notes file. o The file is used to document all changes to the data resulting from the QA process. o Questionable, but unchanged, data is also identified in the file. •!• Monthly QA Report. o The project has a Monthly Report for each month, beginning with the first month of station operation. o The report contains: • Title with the project name and date of the report. • Date report prepared and by whom. • Project short title. • GWS project number. • GWS project manager. • Any cooperator or sponsor IDs, agreement numbers, etc. • A list of project stations. • Description of data type; e.g., Meteorological, Stream, & Diagnostic Data. • Summary. • Introduction. • A Quality Assurance Review section summarizing the QA process. • A Measurements section detailing the measurements being made by the stations. • A Quality Assurance Results section summarizing the results for that month including data summaries and graphs. It will present and attempt to explain any out-of-range data, as well as any observed questionable, incomplete, or bad data. • A section explaining any abbreviations or acronyms used in the document. 1-3 APPENDIX J. SUSPENDED SEDIMENT ANALYSIS The following information reports the suspended sediment analysis which was conducted in cooperation with an Alaska Department of Transportation and Public Facilities (AKDOT&PF) project through University of Alaska Fairbanks (UAF). This analysis was not part ofthe original project objectives or funded by the Alaska Energy Authority (AEA). Grab samples taken from the streams by GWS personnel were analyzed in the lab at the Water and Environmental Research Center, University of Alaska Fairbanks, to determine total suspended solids (TSS). Following ASTM Standard 3977-97, the samples were vacuum filtered through Whatman GF/C glass microfiber filters with particle retention of 1.2 m. The percentage of organic matter in each sample was then determined using ASTM Standard 2974 (Test Method C), in which samples are placed in a muffle furnace at 440°C for twelve hours. The following table (Table J-1) shows the TSS calculated values. The data indicates a clear reduction in suspended sediment concentration in the sampled streams after breakup; additionally, some sites (including the Upper Cosmos Creek and Upper Dahl Creek stations) show a gradual increase in suspended sediment load throughout the summer months.

SELECTED DAILY UPDATES The following information reports field events as described in selected daily updates sent to the project group. K-1 Daily Update: 8/18/10-8/19/10 Will combine reports for August 18 and 19 Current Weather: low fog and clouds, cannot see ridges, mild winds, hope to see fog burn off this afternoon Weather on 18th: rain at our location most of the day, dried out rain gear twice between field trips, cloud cover most of day, broken in evening Weather on 19th: low fog and clouds in morning, burned off in early afternoon, then scattered high clouds, 18th's Tasks: We completed the tasks at Upper Kogoluktuk River Station, installed the Hobo sensor at the Lower Kogoluktuk Station (will be a hike in during winter condition, steep slopes down to river), completed Upper Cosmos Creek Station, Lower Cosmos Creek Hobo station (at end of day on final pickup we had company at our LZ, see pictures, no problems, were prepared) 19th's Tasks: Prepped in camp in morning, weather lifted in afternoon, completed Kogo Repeater, moved and relocated Wesley Repeater when clouds lifted, installed Cosmos Creek Repeater, installed Welsey Creek Repeater, did sling load of gear to Dahl Creek repeater, worked into late evening. All stations now reporting to temp base station set up in Dahl Creek Camp. Today's Tasks: Will complete Upper Wesley Creek Station by 4-wheeler, Lower Wesley Creek Hobo station, may complete Dahl Creek late, if fog burns off will complete Dahl Creek Repeater. Will also meet with school about base station in Kobuk. Since we started on 10th, have had a little over 4" of rain, creeks and Kogoluktuk River are up. Kogoluktuk River was visibly more turbid. Daily Update: 8/20/10-8/21/10 Will combine reports for August 20 and 21 , both were long days. Current Weather: broken high clouds, no rain, ridges have been visible last two days, no morning fog, warm, caribou are showing up on North side of Cosmos Hills Weather on 20th: low ground fog and clouds in morning, clearing in later afternoon, scattered high clouds in afternoon, scattered light showers Weather on 21th: scattered high clouds in morning, no ground fog, ridges clear! 20th 's Tasks: -Prepped in camp in morning, station work continued with Wesley Creek, installation of the PT's and Camera. Water level measurements, stream stage was still higher due to recent rains -Met with Art Finkenbinder, Northwest Arctic School District, at Kobuk School. They are in a transition with no principle (recent change), and needing additional teachers (math and science), We worked out using the school's Internet services for the base station, Art had previously been a teacher at Kobuk for K-2 -6 years, We were also lucky in that Judy Richards, Northwest Arctic School District Technology Director, was in Kobuk for day, so we worked out the network location and interfacing for the Cosmos Hydrology Network base station. She had her staff in Kotzebue help us that afternoon. The school uses GCI school access, which we use in a variety of other villages , so we should not have a problem getting the final network configurations working . -We will be working with teachers at Kobuk School and district to incorporate the data from the Cosmos Hills Hydrology Network into various applications and curriculum for the students, this is being done as a GWS contribution to the schools -The ridges cleared up in late afternoon, so we installed the last of the repeaters for the Dahl Creek Watershed. The attached pictures show the repeater after completion and the upper Dahl Creek Watershed area. The repeaters are designed to operate year round, off solar power, and be resistant to animal damage and environmental conditions. Battery voltage, solar panel output, temperature inside the enclosure and shielded air temperature. The repeaters will report this data online . 21st's Tasks: -Did the last Helo tasks , it returned to Wasilla after we were done -Photos of upper and lower Kogoluktuk site, water level measurement at upper Kogoluktuk site -Installation of lower Wesley Creek hobo station -Air photos of Middle Dahl Creek station (stream temperature), in attached photo, water is flowing towards top of photo, station is on cut bank in deepest section to provide data for estimated longest period before freeze-up -Installation of base station at Kobuk School -packing and sent Austin back to Fairbanks with one load of gear on Wright's (Navajo) -cleaning up in camp with Nova Gold (note: we have been working closely with Nova Gold staff and sharing resource when needed to help develop a good long-term relationship with them, important for the network operations) -James and I are staying to complete final tasks and get base station running with GCI and School District IT staff Today's Tasks: Will complete Upper Dahl Creek installation (Solar Panel, camera, measure water levels), collect additional water level measurements at Wesley Creek and check station operation, work on base station at School and GCI tech support, pack and prepare to leave Dahl Creek camp tomorrow. Daily Update: 10/13/10 I will do a series of daily reports for the current October field trip for the Cosmos Hills Hydrology project. This is our second field trip to the Cosmos Hills Networ1< and the last trip for 2010. Please let me know if you have any questions. Yesterday , Jeff Derry, Jeff Murray, and Dave Brailey arrived in Kobuk. We are using the school as a base to work out of, and Kobuk school is providing both some office and storage space, as well as sleeping and eating areas . This is one of the positive outcomes of our current and planned future work with teachers and kids . The workplan for the field trip is available on the Internal project Wiki: http ://cosmos .gwscientific.com/Workplans/Workplans (hydropower) K-3 -Primary trip objectives: stream gauging, station maintenance (including resetting pressure transducers for winter and spring 2011 measurements}, observations of icing and general hydrologic conditions of the selected watersheds. We are also adding to three sites, some prototype DC camera lens heaters to so we can attempt to extend the stream and river observations later into the winter, and be able to de-ice camera enclosure lens in the spring . Current Weather: temperatures have been holding steady around -SC. Ice has been developing at streams and the Kogoluktuk River over the last week. Some good examples are shown below. The field crew visited Dahl Creek yesterday afternoon and measured stream discharge, did some station work, and saw caribou all over the place, some example pictures are attached. The Bearing Air helicopter should arrive this morning and we will plan on starting our measurements and site work at Cosmos Creek. As icing develops on streams and rivers, there will be impacts on the stream/river rating curves . The relationship between stream gage height and discharge will start to fluctuate and not be predictable. The camera images become critical for understanding this during this early winter period. As the hydropower assessment is interested in how long water may be available during the early winter months, this becomes more important. Some good examples of stream icing is available on the following links ; http ://www. cosmos hydro. org/stations/24h r archive. php?cam= UCosmosC rk&mon= 1 O&dat= 13&yr= 1 0 -Cosmos Creek yesterday, once you look at this, change the date to 10/9/10 and compare the difference The Kogoluktuk River is more than half covered with river ice at the station section , see ; http ://www.cosmoshydro.org/stations/24hr archive. php?cam=UKogoRvr&mon=1 O&dat=13&yr=1 0 -the river ice is currently snow covered, if you go to 1 0/9/10 you will see ice is already forming on the east bank and you can make out frazzle ice in the river (click on pictures for larger images) -you can easily move to other dates and see the changes in the river conditions and chose pictures with certain lighting conditions to see features of interest -All, you will see new content on the educational page, please test out your knowledge of hydrology and lnupiaq on the crossword puzzle. We also have some of our Texas A&M University students working on additional educational material for the school : http ://www.cosmoshydro .org/education .shtml Wright's air staff had some good comments about the help the real-time data reporting will give them in flight logistics for the area. Daily Update: 10/14/10 Yesterday, the Bering Air helciopter arrived at Dahl Creek campground around 10:45. Jeff Derry, Jeff Murray, and Dave Brailey soon left for Cosmos Creek. The weather was good during the day and you can see some of their activity at images (see below links) at both Cosmos Creek and Wesley Creek. http ://www.cosmoshydro .org/stations/UCosmosCrk/current.shtml -go to 24 hour images, then change date to 14th K-4 http://www.cosmoshydro.org/stations/UWesleyCrk/current.shtml -go to 24 hour images, then change date to 14th A summary of work accomplished yesterday; -Discharge measurements at Upper Cosmos Creek and Upper Wesley Creek -Upgrade of Upper Cosmos Creek Camera with lens heater system -Station maintenance at Upper Cosmos Creek Station -Surveying and resetting PT's at Upper Cosmos Creek Station -Site visits to all four repeater stations A couple of pictures are attached for the Upper Cosmos Creek station area . The crew will tackle the Kogoluktuk River today. Daily Update: 10/15/10-10/17/10 This will be a combined report for Friday (Oct 15) through Sunday (Oct 17). A summary of work accomplished in the last three days; -Discharge measurements at Upper Kogoluktuk River (this completed all four streams/rivers -all Q measurements met QAQC review, duplicates at each site) -Upgrade of Upper Kogoluktuk River and Upper Dahl Creek Cameras with lens heater systems -Station maintenance at Upper Kogoluktuk River, Upper Wesley Creek, and Upper Dahl Creek -Surveying and resetting PT's at Upper Kogoluktuk River, Upper Wesley Creek, and Upper Dahl Creek -Site visits to all four stream monitoring sites (Lower Cosmos Creek, Lower Welsey Creek, Middle Dahl Creek, and Lower Kogogluktuk River), Hobo sensors were either swapped out or data was downloaded from each site. See http ://www .cosmoshydro .org/network .shtml for current site conditions. There is less daylight each day, so the first visible camera image is getting later each week. A couple of pictures are attached for the Upper Welsey Creek showing the discharge measurement section with a tag line across the creek . Caribou continued to provide some surprise visits on site . Cosmos Creek was also revisited to collect additional water level measurements. A picture of the changing icing conditions is shown from just upstream of the site. The crew is giving some presentations to the school today and working with some of the teachers. If needed, they will revisit Dahl Creek. K-5 Weather/River Report: 5/11/11 The Cosmos Hydrology Project group will be going in the field next week for spring snowmelt field measurements. I will send out periodic notes on weather/river conditions to help report current conditions in the Kobuk area. The high snowpack conditions may lead to high water conditions for the Kobuk area this spring, depending on weather conditions over the next few weeks. The Kogoluktuk River Gage and USGS Dahl Creek gauges are currently reporting, though both are still under ice-affected conditions. We anticipate visiting the repeater sites for Cosmos, Wesley, and Dahl Creeks later next week to replace radios and get the remaining stations online. The warm spell at the end of April and early May resulted in the water level increases on the Kogoluktuk River of about 2 feet, but it has dropped with the recent cooler weather in the last 5 days. see 14 day water height of sensor hydrograph at: http://www.cosmoshydro.org/stations/UKogoRvr/graphs/waterDepth avg 14day.png -for images on the 5th, see: http://www.cosmoshydro.org/stations/24hr archive.php?cam=UKogoRvr&mon=5&dat=5&yr=11 the east bank (lower portion of image) shows water starting to rise over the top of the snowpack along the left bank -you can change the date for the 24 hour image summary to see conditions before or after this date -see 14 day temperatures at: http://www.cosmoshydro.org//stations/UKogoRvr/graphs/air 14day.png -General station current conditions are available at: http://www.cosmoshydro.org/stations/UKogoRvr/current.shtml The USGS Dahl Creek Gage is available online at: http://nwis.waterdata.usgs.gov/aklnwis/uv?cb 00065=on&cb 00060=on&format=gif default&period=14& site no=15743850 -this site is located just east of the Dahl Creek Airstrip, water levels indicate some local melting during warm periods, but still ice affected conditions no sustained increase in streamflow The USGS gauge at the Kobuk River Near Kiana is not yet reporting. This is the first year for data availability for the Kogoluktuk River. The USGS Dahl Creek Gauge (a valuable asset in this region) has data going back to 1986. For a current description of the Cosmos Hydrology Project, the following two links provide background information; -Project website: http://www.cosmoshydro.org/ -Recent Alaska Section, AWRA, Overview Presentation: http://state.awra.org/alaska/meeting2011.html#top -see Brailey presentation in Session 8 Weather/River Report: 5/16111 The Cosmos Hydrology Project group will be going in the field Wednesday for spring snowmelt/runoff field measurements. This note is part of our periodic notes on weather/river conditions to help report current conditions in the Kobuk area. The high snowpack conditions may lead to high water conditions for the Kobuk area this spring, depending on weather conditions over the next few weeks. The Kogoluktuk River Gage and USGS Dahl Creek gauges are currently reporting, though both are still under ice-affected conditions. We anticipate visiting the repeater sites for Cosmos, Wesley, and Dahl Creeks later this week to replace radios and get the remaining stations online. The warming temperatures over the last few days have caused the Kogoluktuk River water levels to increase again and they are now higher than May 5th. Water can be seen along the east bank of the river K-6 in the images, and water can now be seen on the opposite bank above the snowpack along the bank. The ungrounded ice in the center of the channel is likely moving the upper level of the snowpack higher as water levels increase. see 14 day water height of sensor hydrograph at: http://www.cosmoshydro.org/stations/UKogoRvr/graphs/waterDepth avg 14day.png -for images on the16th, see: http://www.cosmoshydro.org/stations/24hr archive.php?cam=UKogoRvr&mon=5&dat=16&yr=11 -the east bank (lower portion of image) shows water starting to rise over the top of the snowpack along the left bank -you can change the date for the 24 hour image summary to see conditions before or after this date -see 14 day temperatures at: http://www.cosmoshydro.org//stations/UKogoRvr/graphs/air 14day.png -temperatures have been getting into the 50's but still dropping just below breezing -General station current conditions are available at: http://www.cosmoshydro.org/stations/UKogoRvr/current.shtml -The following is an internal graph, showing the water level above sensors for the two pressure transducers at the Kogoluktuk river Gauge. one sensor is one the channel (deeper water level), and the other was located on top of the river ice at bank last October. -http:/ /www.cosmoshydro. org/ /stations/UKogoRvr/graphs/waterDepths avg 14day.png The USGS Dahl Creek Gage is available online at: http://nwis.waterdata.usgs.gov/aklnwis/uv?cb 00065;::on&cb 00060;::on&format;::gif default&period=14& site no= 157 43850 -this site is located just east of the Dahl Creek Airstrip, water levels indicate stream flow is increasing, though the stream is still expected to be under ice affected conditions The USGS gauge at the Kobuk River Near Kiana is not yet reporting. Weather/River Report: 5/19/11 The Cosmos Hydrology Project group is now in the field for spring snowmeiUrunoff field measurements. Below are current conditions in Kobuk and Cosmos Hills area. The Kogoluktuk River Gage and USGS Dahl Creek gauges are currently reporting, though both are still under partial ice-affected conditions. The Kogoluktuk River has ice moving in the reach of the station and camera, it is clear downstream and some sections upstream. Ice concentrations are changing hourly. The USGs· Dahl Creek Gage should be reading close to none-ice affected conditions. We anticipate visiting the repeater sites for Cosmos, Wesley, and Dahl Creeks on Saturday to replace radios and get the remaining stations online. The Kobuk River has come up about three feet since last night. -see 14 day water height of sensor hydrograph at: http://www.cosmoshydro.org/stations/UKogoRvr/graphs/waterDepth avg 14day.png -water levels are continuing to rise each day see 14 day temperatures at: http://www.cosmoshydro.org//stations/UKogoRvr/graphs/air 14dav.ona temperatures have been getting into the 50's and have not dropped below freezing the last few days -General station current conditions are available at: http://www.cosmoshydro.org/stations/UKogoRvr/current.shtml -The following is an internal graph, showing the water level above sensors for the two pressure transducers at the Kogoluktuk River Gauge.

Weather/River Report: 5/22/11 -High overcast skies today at Dahl Creek Camp and Kobuk -All four repeaters and Wesley, Dahl, Kogoluktuk Stations reporting data: http://www.cosmoshydro.org/network.shtml -some graphics will be restarted on Monday note: time reporting is AST (Alaska Standard Time) -Water levels in town are dropping slowly, this morning, the road to the airport still had 3+ feet over the road -Main ice accumulation in Kobuk seemed to go out yesterday afternoon Further stage changes in Kobuk River mainly snowmelt+ any precipitation -Major flooding for Kobuk seems to be over not counting snowmelt Daily Update: 5/22/11 -Today was spent on the following, not the issues at Cosmos -Upper Cosmos Creek station visit, see attached pictures station is covered by a small avalanche, a few rocks, torn out trees, etc were observed -in the attached pictures you will see a snow marker (blocks of snow piled on top of each other) indicating the location where the station should be, there is about 12-15 feet of snow over the general area the avalanche extend past the exposed area in the tundra where initial water flow moved around the snow obstruction, the creek is now flowing under the avalanche, with some flow around it -we will need to see what emerges during snow melt to know what damage was done to the station there is still a lot of icing in Cosmos Creek upstream and downstream of the site, so will hold off a few days on any discharge measurements, will visit the site again in a few days site visit to Kogoluktuk River -pressure transducers were pulled up along bank by ice -one pressure transducer was pulled off cable (pulled apart flex liquatite), this was resulting in excess voltage drops in battery bank due to 12v power lines (low voltage/amperage) in the water from the pulled apart cable, we pulled this from the site -we did tests on the remaining pressure transducer and re-installed it and surveyed in new measurement rebar control (RP) -we also prepped the raft and gear for discharge measurements, the ice concentration was still high with some blocks coming down more than 10 feet across, we will need to wait for safer water conditions to get discharge measurements, will try again tomorrow 7 of the 8 stations (stream/river/repeater) are reporting. Cosmos will have to melt out more before we can deal with it. We will return to the Kogoluktuk River station tomorrow, though forecast is for showers and thunderstorms, so may only be able to spend part of a day there. K-13 Dahl Creel and Wesley Creek are still coming up. There is a lot of snow in the 3 Creek Basins and the Kogoluktuk River Basin .

Brent Petrie (AVEC), Jay Hermanson (WH Pacific), Dave Braily and myself arrived Monday afternoon in Dahl Creek Camp. Alan Ward and Jason Moyer, both of Kobuk, were here to meet us. Ron Pierce, Nova Gold, had us all setup with lodging and supporting coordination. The primary purpose of this trip is the final measurements and decommissioning of the Cosmos Creek and Dahl Creek sites, and the start of winter season refinement of flow conditions on Wesley Creek and the Kogoluktuk River. Monday, 9/19 -We measured the Kogoluktuk River discharge: 919 cfs, 4. 7% error -took Brent and Jay on a fly over tour of Cosmos Creek, Ruby and Wesley Creeks, Dahl Creek and the portion of the Kogoluktuk river from the middle of Ambler Lowlands to the lower falls area along the south flank of the Cosmos Hills -We also inspected the intertie line between Shungnak and Kobuk Tuesday, 9/20 -Dave measured Wesley and Dahl Creek upper sites -Wesley Creek: 24.5 cfs, 3.2% error -Dahl Creek: 43.5 cfs, 1.2% error -Dave also took Jay and Brent to the Upper Welsey Creek station and upper area for an on the ground inspection of the creek and local terrain conditions -Alan Ward then took Brent, Jay and myself on a tour and Kobuk infrastructure and we met with one the teachers at Kobuk School -Brent and Jay then left on the late morning flight To help refine the winter flow conditions on the Kogoluktuk River, an Upper Kogoluktuk River axillary site will be located today, along with recon work to identify a potential winter trail route for access to the Upper Kogoluk Station area during winter conditions. Daily Update: 9/21/11 The crew focused on training in the morning, and preparation for the establishment of the Upper Kogoluktuk Supplemental Winter Station. Wednesday, 9/21 We measured the Kogoluktuk River again today to help start the establishment of a supplemental winter station located in the upper falls area -We located most of the winter trail section we will use, this will be flown more closely this weekend. Most of the trail exists, but needs some clearing. -We located the Upper Kogoluktuk Supplemental Winter Station located and started water level measurements today to combine with the discharge measurement, and worked out many logistical issues associated with work down in this station during summer and winter locations. The attached pictures show you some of the river conditions down in the upper falls. The bare and polished rock down near the bottom is likely the result of the annual snowmelt flooding, associated with high concentrations of broken up river ice from the Upper Kogoluktuk River. For references, this is likely flooding with ice coming down the size of 4-wheelers and small minivans choking the channel and raising flows up an average of 15 to 20 feet above the water levels we saw today.

The geologic bed formation result in the west bank (left hand side of picture) sloping steeply into the water, and the east bank (right hand side of picture) sloping away from the river -the water is clear, the rocks you see in the channel bottom are several meters across Cosmos_Kogoluktuk_River_ Upper_Falls_Winter_Station_11 0921_mri_P921 0095.jpg -Alan Ward is holding a survey rod on the west bank, so we could measure water levels while Dave was •nc::trP~m doing a doppler discharge measurement. Alan is wearing a floatation jacket. Cosmos_Kogoluktuk_River_Upper_Falls_Winter_Station_11 0921_mri_P921 0122.jpg -Dave is just upstream of the site in the first bend entering the falls area, the clean rock areas on the bank are kept polished by high flows (flood events), likely the most important being snowmelt when high concentrations of river ice are coming down the river and concentrated in the falls area. Tomorrow we will work out the station installation logistics, safety preparations, and attempt the doppler profiling of the channel in pool area. K-28 Daily Update: 9/22/11 Below is a brief summary of work performed yesterday. We stayed in Dahl Creek camp to work on gear preparation and training. Thursday, 9/22 -The crew focused on site preparation for the Upper Kogoluktuk Supplemental Winter Station -Training for Alan Ward and Jason Moyer on surveying and water level measurement techniques Today we will work with available Helo logistics to visit the Upper Kogoluktuk Supplemental Winter Station, and Upper Cosmos Creek Station for a final discharge measurement at this location. We will also work on winter planning for the Upper Kogoluktuk Supplemental Winter Station, when conditions will include ice and snow cover. Daily Update: 9/23/11 Below is a brief summary of work performed yesterday.

METEOROLOGIC DATA PLOTS The following graphs report selected information collected from data stations. These graphs present data for individual stations for the period of record. Most of the stations have continuous data from August 2010 to the most recent data collection date in January 2012. The Upper Cosmos Creek and Upper Dahl Creek stations were discontinued in September 2011. The Upper Cosmos Creek station was damaged by an avalanche in February 2011 and most data collected afterwards by this station was deleted as being unreliable. The data represent single readings taken once per hour, at the top of the hour, except for the rainfall data which are hourly totals.

HEALTH, SAFETY, AND ENVIRONMENTAL The following information summarizes the health, safety, and environmental precautions taken throughout the project. A series of hazard assessments were performed and evaluated for mitigation steps before the project began. The safety and environmental issues of concern, as well as the steps taken to ensure the health and safety of the field crews, are summarized in the following pages. 0 -1 Health, Safety, and Environmental Summary Daily reporting to principle project participants occurred via email or telephone, and updates were made to other entities as requested or appropriate. To ensure project participant's safety, continual risk assessments and the completion of applicable training occurred. Staff had prior experience in the activities planned during field trips and completed any relevant training, including; helicopter safety training, swift-water rescue training, bear and gun training, and outdoor survival skills training. The following safety issues were considered during the planning of field trips. I. General Safety-A Task Hazard Analysis (THA) was performed by personnel before each trip and a safety meeting including all field personnel took place every morning while in the field. A SPOT tracking device was used to log locations and was checked each day for operations. 2. Driving Safety-Safety videos were watched and all safe-driving practices were followed. 3. Helicopter Safety GWS staff attended helicopter safety training classes as required by BLM personnel. Helicopter helmets were worn by project participants and staff carried a personal emergency kit in their pockets while flying in case of an emergency exit situation. A pilot safety awareness briefing was given before each flight day. 4. Stream Gauging Water Safety Swift-water safety/rescue videos were watched and the utmost safety practices were followed at all times while working near streams/rivers. Rapid high water conditions required the use of dry suits, and life vests were required when working around water that was more than 3 ft deep. 5. Use of Hand tools All regular safety practices were followed with use of hand tools, including the use of safety glasses and gloves when necessary. 6. Bear Safety -All GWS staff participated in a l day bear and gun safety training class. A shotgun and/or pepper spray was available in the field for bear protection if needed. Only staff having current security checks, bear safety classes, and shotgun classes were permitted to handle firearms. Firearms were stored safely and in appropriate locations at all times. When accessing sites by helicopter, initial flyovers included bear spotting, and when applicable, one person served as bear watch once on location. 7. First Aid-A large first aid kit was stored at the camp, while several portable first aid kits were brought to the field each day with project staff. In addition, Geo-Watersheds Scientific staff had Wilderness First Responder and Emergency Medical Technician training. 8. Waste Management-The staff adhered to strict waste management practices. Any food or garbage remaining from items carried into the field was packed out with the field crew and environmental conditions were left as close to unaltered as possible. 9. Remote Activity Safety-Remote activities, such as environmental sampling or maintenance at unmanned sites, were accomplished with two team members on site or with a single team member accompanied by local hire personnel. A survival bag or tote was provided and taken into the field when there was any possibility of an extended stay at a remote location. This ensured the crew had the necessary supplies to maintain a camp for several days if, for instance, weather prevented a scheduled helicopter pick up. 0-2 10. Weather Conditions and Field Work -In general, field crews are prepared to work in extreme conditions, but careful consideration of winter working conditions were evaluated during each field trip. As a general rule, weather days should be taken when wind chill factors are less than -60 oF (Figure 1 ). Between -60 and -40 oF , field work should be considered for rescheduling, depending on location and type ofwork involved. During weather conditions with temperatures less than 0 oF, tenting/shelters should be used as practical. Field staff should take breaks while working in the cold, using Table 1 as a general guide for safe working conditions . The Trip Leader would make the decisions on weather-related trip schedule changes.
