Units
For the purposes of this report, both US Customary and Metric units were employed.
Common regulations related to water use in Alaska uses combinations of both US
Customary and Metric units. The choice of "primary" units employed depended on
common reporting standards for a particular property or parameter measured.
Whenever possible, the approximate value in the "secondary" units was also provided in
parentheses. Thus, for instance, snow depth was reported in inches (in) followed by the
value in centimeters (em) in parentheses.
Physical and Chemical Water-Quality Units:
Temperature:
Water and air temperature are given in degrees Celsius rc) and in degrees Fahrenheit
rF). Degrees Celsius can be converted to degrees Fahrenheit by use of the following
equation:
OF= 1.src) + 32
Snow Water Equivalent (SWE):
Water content of a given column of snow is determined by knowing the depth of the
snowpack and density.
SWE = ds *PsI Pw
where:
ds =snow depth
Ps = snow density
Pw = density of water.
Electrical Conductance (Actual Conductivity and Specific Conductance):
In this report conductivity of water is expressed as Actual Conductivity [AC] in
microSiemens per centimeter (IJS/cm). This unit is equivalent to micromhos per
centimeter. Elsewhere, conductivity is commonly expressed as Specific Conductance at
VIII
25°C [SC25] in j.JS/cm which is temperature corrected. To convert ACto SC25 the
following equation can be used:
Error! Bookmark not defined. SC25 = AC
l + r(T-25)
where:
SC25 = Specific Conductance at 25°C, in j.JS/cm
AC =Actual Conductivity, in !JS/cm
r = temperature correction coefficient for the sample, in °C
T = temperature of the sample, in °C
Milligrams per liter (mg!l) or micrograms per liter (ug/1}:
A milligram per liter is a unit of measurement indicating the concentration of chemical
constituents in solution as weight (milligrams) of solute per unit volume (liter) of water.
One thousand micrograms per liter is equivalent to one milligram per liter. For
concentrations less than 7,000 mg/1, the numerical value is the same as for
concentrations in parts per million (ppm).
Millivolt (mV):
A unit of electromotive force equal to one thousandth of a volt.
Vertical Datum:
"Sea level" in the following report refers to the National Geodetic Vertical Datum of 1929
(NGVD of 1929), a geodetic datum derived from a general adjustment of the first-order
level nets of both the United States and Canada, formerly called Sea Level Datum of
1929.
Horizontal Datum:
The horizontal datum for all locations in this report is the North American Datum of 1983
or North American Datum of 1927.

Cosmos Hills Hydrologic Network Installation and
Operations, August 201 0-December 2011
1.0 INTRODUCTION
Alaska Village Electric Cooperative, Inc. (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.

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.

The Lower Dahl Creek USGS Station is important in the Cosmos Hills region, as it
serves as a representative stream for south facing watersheds in the lower foothills. 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.

stayed at a high charge capacity during winter months and solar charging started to
increase in February and was meeting the daily energy consumption in March. When
15
the battery banks are fully charged (will not accept additional amps), the solar panel

3.1 UPPER COSMOS CREEK STATION
The Upper Cosmos Creek Station was located in the upper portion of the Cosmos
Creek watershed, at an approximate elevation of 684 feet above sea level. The station
was located on the west bank of the creek, also called the "right bank" as viewed by an
observer looking in the downstream direction. The station was located a few hundred
feet to the east and southeast of the primary helicopter landing zone. The general
channel conditions appear to be well anchored cobbles and boulders. Some boulders
are over 3 feet (-1 meter) in diameter. There is brushy vegetation along both banks and
signs of overflow channels in the right overbank area. The left bank is located against a
talus slope from the adjacent Cosmos Mountain. The stage levels were measured in the
creek just upstream from the large rock shown in Figure 7. The survey control points
16
were located both upstream and downstream of the station location . The discharge
measurement locations varied upstream and downstream based on flow conditions at
specific water level conditions. This station was discontinued in September 2011 .

3.2 LOWER COSMOS CREEK STATION
The Lower Cosmos Creek Station was located on the east bank (left-hand bank), just
downstream of a regional trail (Figure 8). The location was chosen on a deep cut bank
so that there would be a greater chance of the sensor being under ice and not frozen in
during winter months. The general stream conditions are well mixed so the temperature
data should be representative of the general stream reach . There is thick vegetation on
both sides of the stream and the stream bed is primarily composed of gravel and
cobbles. Data collection at this station used a Hobo stream temperature sensor and
17
manual general stream observations . There was no real-t ime reporting from this station .
This station was discontinued in September 2011.

The Lower Wesley Creek Station is located on the west bank (right-hand bank), just
downstream of a regional trail and old 4-wheeler bridge (Figure 1 0). The location was
chosen on a deep cut bank (center of photograph) so that there would be a greater
chance of the sensor being under ice and not frozen in during winter months. The
general stream conditions are well mixed. There is thick vegetation and scattered
spruce trees on both sides of the stream and the stream bed is primarily composed of
gravel and cobbles. Data collection at this station uses a Hobo stream temperature

3.6 MIDDLE DAHL CREEK STATION
The Middle Dahl Creek Station was located on the west bank (right-hand bank), just
downstream of a bend and clearing along the creek (Figure 12). The location was
chosen on a deep cut bank so there would be a greater chance of the sensor being
under ice and not frozen in during winter months. The general stream conditions are
well mixed so the temperature data should be representative of the general stream
reach . There is thick vegetation and abundant spruce trees on both sides of the stream
and the stream bed is primarily composed of gravel and cobbles. Data collection at this
station used a Hobo stream temperature sensor and manual general stream
observations . There is no real-time reporting from this station . The USGS Dahl Creek

The Lower Kogoluktuk River Station is located on the west bank (right-hand bank), just
downstream of the upper falls area (Figure 15). The location was chosen on an outside
bank so that there would be a greater chance of the sensor being under ice and not
frozen in during winter months. The general river conditions are well mixed so the
temperature data should be representative of the general river reach . There are large
bedrock exposures on both sides of the river. The riverbed in this reach is likely a mix of
bedrock , boulders and gravel. Data collection at this station is with a Hobo stream
temperature sensor and manual river observations . There is no real-time reporting from

4.0 SELECTED RESULTS AND DISCUSSION
This section provides a summary of data collected during the 2010-2011 reporting
period. 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).

4.2 STREAMFLOW COMPUTATIONS
Computation of daily streamflows was accomplished using corrected stage data and
preliminary rating curves developed for each station. 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.

during the winter months, which are assumed to reflect ice formation on the
transducers.

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.

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).

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.

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).

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.

Although no data supports the lower rating curve segment, the gauge offset (90.97 feet)
and the rating exponent (2.485) for the upper segment are consistent with the control
geometry (Figure 25). 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.

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.

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.

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.

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.

4.4 SPRING SNOW MEASUREMENTS AND FIELD OBSERVATIONS
The general snow conditions were fairly uniform at sites measured during the March
2011 field trip, Figure 34. 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

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.

5.0SUMMARY
A surface-water data collection network was established in the Cosmos Hills region in
August 2010 for the purpose of evaluating the hydropower potential for Cosmos Creek,
Wesley Creek, Dahl Creek and the Kogoluktuk River. 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.

APPENDIX F. SNOW SURVEY FORMS
The following forms report the snow survey information obtained during field
sampling. Density was not sampled at sites Kogo Forest, Wesley SC 1, or Wesley
SC5. The regional snow density patterns vary less than snow depth, so a subset of
the sites were used for density measurements.

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.

APPENDIX I. 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.

APPENDIX K. 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.

-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.

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.

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.

The USGS gauge at the Kobuk River Near Kiana is not yet reporting.
Villagers are preparing for potential flood conditions. Various ice jams have come and gone by the village.
Up by Dahl Creek in the area of the USGS gage, the snowpack is wet throughout, many areas with
standing water in the snowpack.
Daily Update: 5/19/11
-The Cosmos Hills Hydrology team arrived at Dahl Creek Camp yesterday on Wrights. We flew a loop up
the Kogoluktuk and then to the Bornite mine, up Ruby Creek and down Wesley Creek to Dahl Creek
Camp airstrip. There is less snowmelt on north side of the Cosmos Hills, Bornite Road still has a lot of
snow north of the pass, mainly clear south of the pass (between Wesley and Ruby Creeks)
-We brought in some parts for Nova Gold, no weight issues with flight
-Johnette asked us to help Alex Sheldon and family, his sister was in Fairbanks hospital and not doing
well. We sent back on the plane Alex, Rosa Horner, Sherry Horner and 3 children back to Fairbanks,
taking advantage of an empty flight going back
-We were able to setup in our same office tent as last August (Thanks Frank!-Nova Gold)
-Allan Ward met us with the 2 4-wheelers we are renting, one is from Johnette. Allan is working with us
as we need help, and he helped us during the passt March trip
-We are settled in at the school and they have been very helpful
-We got equipment setup yesterday, took pictures of the Dahl Creek USGS Gage, and worked out Nova
Gold camp logistics with Frank
Today, we are testing discharge equipment and the raft on the Kobuk River in available open sections
-The helicopter is delayed by a day and will show up on the 21st
The road is clear to Wesley Creek and we will be doing discharge measurements and station work there
tomorrow
-We will be working out plans for locating 4-wheelers and gear in case we need to move out of Kobuk
due to flooding, the school is high enough not to be a problem, but the access road to Dahl Creek Camp
will be cut off
-Weather and snow conditions are such that peaks on the streams should occur during the next week.
The Kogoluktuk has also come up and now has more ice coming down from the Ambler flat region. Still a
lot of snow in the upper basin based on flying in yesterday
We ate dinner with several local folks from Kobuk and Ambler, they have not seen this much snow in a
long time, were able to do winter travel to areas they normally can not get to, snow cover has likely
resulted in thinner ice cover on the rivers this year
Weather/River Report: 5/20/11

Daily Update: 5/21/11
-With river levels moving up, we move to Dahl Creek Camp late Thursday night. Be early morning water
was over the access road to the airport
-Frank, Nova Gold, has been very helpful, we are. using the office tent used last year, plus one other tent
while camp numbers are down
-We gauged Welsey Creek yesterday, making 2 discharge measurements, the stage was increasing
while we were there
-the station and PT's were working fine, as well as camera
-we also surveyed accessible RM's and RP's
-We checked out water levels in village and worked on continued preparations for field work and worked
up data collected at Wesley Creek
-We measured gauge heights at the Lower Dahl Creek USGS station and recorded other field
observations
-the Helo is scheduled to get in this afternoon and we anticipate getting to repeater sites and the Upper
Kogoluktuk River Station today, there is a potential power issue with the station which may be related to
PT's getting pulled out yesterday afternoon by ice .
-the rain over the last 2 days and sun today will continue to accelerate snow melt in the area
Weather/River Report: 5/21/11-Kobuk Flooding
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
K-11
-the attached pictures show Kobuk this evening, under current flooding conditions
-the ice jam on the Kobuk went out late this afternoon, it was several miles long according to pilots flying
into kobuk
-the main problem people seemed to have were ice impacts
-the attached photos were taken this evening on our return Helo trip, you can see lots of river ice left on
town from higher water levels
-see 14 day water height of sensor hydrograph at:
http ://www . cosmoshyd ro . org/stations/U KoqoRvr/g raphs/waterDepth avg 14dav. ono
-water levels are impacted by ice pulling the sensors downstream and into shallower water along the
bank, we will plan on visiting the site to fix the sensors tomorrow
Daily Update: 5/21/11 (evening)
-The helicopter arrived late this afternoon, after getting settled, we went out for a short trip
-aerial survey of Kogoluktuk River, Upper and Lower station locations, and gauging portion of the river
-there is still ice coming down the river and lots of ice upstream in Ambler flats
-the pressure transducer lines could be seen pulled in a downstream direction from bank or river ice
-will have to reset PT's, some may need replacement if damaged by ice breakup
-the station may have some issues associated with the PT's being pulled downstream, will confirm on
site visit tomorrow
-replaced the radio at Dahl Creek Repeater Station, it is now reporting as well as Upper Dahl Creek
Station ·
- replaced the radio at Wesley Creek Repeater Station, it is now reporting as well as Upper Wesley Creek
Station
-replaced the radio at Cosmos Creek Repeater Station, it is now reporting BUT the Upper Cosmos Creek
Station is not reporting
-from aerial surveys, it looks like the station area is covered by a large drift and stream icing, will have to
conform on the ground tomorrow
-There is still a lot of snow in Dahl, Wesley, Cosmos Watersheds, which are generally protected from
direct solar exposure
-The shallow gravel bars in the center of the Kogoluktuk River in the reach of the upper station serve to
ground ice and create temporary ice jams, downstream of this point as you get into the curve before the
falls, the channel is narrow and water currents are much faster, little sign of any ice accumulation in this
area
K-12
-the Brooks Range to the North still has a lot of snow, so the Kogoluktuk may have a way to go before
snowmelt peak
The lower Kogoluktuk (below the falls and before the Kobuk) has a lot of ice backed up that may or may
not get into the Kobuk depending on time, teh ice will continue to thin as long as it is held in place
Currently the only station not reporting is the Upper Cosmos Creek Station. We should know more about
this station tomorrow.
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 .
The Kobuk River is not going down much, the lower Kogoluktuk River is packed with ice that could go into
the Kobuk River.
(Photo s A bove of Cosmos Creek Avalanche)
Daily Update: 5/23/11
Today was spent on the following :
-site visit to Kogoluktuk River to gauge discharge
-still truck size pieces of ice coming down, but we successfully dodged ice to find a reach of the Kogo to
do discharge measurements at the current stage
-survey all elevation control in and current water levels, the benchmark control is working out well and we
are tied into our control from last year
-Currently, the online water level reporting represents ice, out, reinstallation of one working sensor, etc.
These numbers will be cleanup after we are out of the field, see for an example:
-http://www .cosmosh ydro.org//stations/U KoqoRvr/graphs/waterDepths avg 14day. png
-on the 19th, PT2 was ripped out by ice flow, this also resulted on a slow power drain on the battery
system due to exposed sensor wires in the water
-on the 20th , PT1 was shifted to shallower water near bank
-on the 21st, PT1 was shifted onto the bank by ice flow
-on the 22nd, PT1 was checked and reinstalled into a temporary position
-on the 23rd, PT1 was checked , and is accurately representing the change in water levels when
QAQC'ed against manual readings
Dahl Creel and Wesley Creek are still coming up. There is still a lot of snow in the 3 Creek Basins and the
upper Kogoluktuk River Basin.

and around the west side of the avalanche drift
May 17 camera stops working when it goes under water (water rises within snow drift)
May 27 -we dug out the station and pulled the datalogger, it was still running though was going to
be impacted by corrosion soon
We have some extra equipment with us, and will attempt in the next few days to get the pressure sensors
on a logger so critical data can be collected before a future complete station repair visit can be planned.
This will depend on the conditions of the battery bank, which we still need to evaluate.

We had a successful day at the Upper Cosmos Creek Station yesterday. The flow was measured 64 cfs
(0 .5% error), with steady water levels while we were there. Cosmos Creek was running crystal clear.
Some photos are attached from yesterdays work. the line across the creek in the aerial photo is the tag
used for the measurement section . Jason Moyer is shown in one of the photos repairing the battery box.
Jason helped us setup the station last year in August. This is the station that was impacted by the
February avalanche. The station is now reporting online with a replacement radio. Note, many sensors
are still not hooked up, so further maintenance is needed .
-two discharge measurements

Daily Update: 8/11/11
We had a successful day at the Upper Dahl Creek Station yesterday, and completed work at the Upper
Wesley Creek Station, and Lower Dahl Creek Station. The flow was measured 46.7 cfs (0.5% error) at the
Upper Dahl Creek site, with steady water levels while we were there. We also did a discharge
measurement on the USGS Lower Dahl Creek site. Dahl Creek was running crystal clear. Some photos
are attached from yesterdays work.
Upper Dahl Creek Station
-two discharge measurements
-water level QAQC measurements
-elevation control surveying
-water chemistry and turbidity sampling
-general station maintenance, replacement of desiccant, etc.
Upper Wesley Creek Station

-elevation control surveying
-general station maintenance, replacement of desiccant, etc.
Lower Wesley Creek Station
-changed out Hobo water temperature sensors, site pictures
-NOTE: we had several observations of fish splashing in the Creek, Jason saw one fish that was 6 to 1 0"
long
USGS Dahl Creek Station (Lower)
-one discharge measurement
-water level QAQC measurements
-this site was measured to help compare our measurement methods and data with the USGS record at
the station
Some of the pictures show a currently conditions on Upper Dahl Creek and Lower Wesley Creek stations .
They also show some of the training we were doing with Jason Moyer (Kobuk), who has been learning
how to be a surveyors assistant, how to measure water levels at the stream reference points, and how to
change out the Hobo data logging sensors. Jason also worked with us last August when the stations were
setup. Both Jason and Allan Ward have been great field support and help reduce the field staff we need
to bring with us .
We will be working at the lower sites today and possibly visit Upper Cosmos Creek again . We leave Dahl
Creek Camp late this afternoon. It is currently pouring down rain (good hydrology conditions).

Daily Update: 9/19/11 and 9/20/11
This is the first daily update for our September trip and will cover Monday and Tuesday of this week.
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.

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

APPENDIX N. 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.

APPENDIX 0. 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.
