Reservoir temperature mod,elling is being utilized to answer questions regarding the reservoir temperature regime.The Dynamic Reservoir Model (DYRESM)developed at the University of Western Australia represents the state of the a rt in one-dimensional reservoi r temperatu re models. However,application of such'a model for cold regions has requi red verification of the model·on an existing system,plus expansion of the model's capabilities to account for thermodynamics of ice formation .in order to adequately describe the winter temperature regime. F"'/ l. t'1JllIM I . The dynamics of sediment transport in the proposed reservoir are also difficult to evaluate without study of the annual variation in reservoir turbidity in a similar environment. Eklutna Lake,twenty five miles northeast of Anchorage Figure 1.1,was chosen for concentrated study to verify the DYRESM model and to calibrate the ice formation model additions.A simultaneous effort monitoring movement of sediment in Eklutna Lake was proposed for comparison with turbidity projections for the Watana Reservoir.Eklutna Lake was chosen because it has bulk residence time,climatological conditions,and glaciated drainage area comparable to the Watana Reservoir (Table 1.1). The data collection"was designed to: n 2) 3) s5/y Provide input data for the DYRESM model. Provide lake temperature data for verification of the DYRESM model.

The succession of bi-weekly profile data sufficiently demonstrates warming trends in the lake,including the development of a weak thermocline and ,the introduction of stream inflow via interflow in the period from June through August.September is marked by the disruption of thermal stratification.Deepening of the mixed layer by penetrative convection and the effects of extreme wind shear on the lake are evident from comparison of the data.By mid-October the overtu rn process dominates the lake;the water column is nearly isothermal',and virtually no turbidity gradient is apparent. Suspended sediment in Eklutna Lake is composed glacial flour,consisting of flaky and angular particles,principally feldspars,quartz,and muscovite.Typical particle densities range from 2.6 to 2.9 g/ml.The vast majority of sediment particles greater than about 30 microns equivalent diameter are apparently deposited in the delta formed where the Eklutna river flows into EkJutna Lake.Mean particle size of sediment carried through the lake is on the order of 3 to 4 microns equivalent diameter.Sediment concentration is shown to vary through the lake.A direct correlation between nephelometric turbidity and sediment concentration is demonstrated. The effect of interflow and underflow of inflow water are evident in seasonal variation in the vertical distribution of suspended sediment. Large (33 micron)concretions of calcium carbonate-aragonite appear near groundwater seepage areas below the lake's su rface at the la ke's lower end.These minerals appear to dominate the sediment regime in July in the lower lake hypolimnion.Hardness,as calcium carbonate,of the influent groundwater is thought to -be the cause of the appearance of the mineral. Light extinction varies significantly on a seasonal basis with changes in su rface turbidity.Correlations have been developed between the extinction coefficient and turbidity and between the extinction coefficient and secchi disk transparency.The extinction coefficient is highest in early August (2.35 m-1 )and lowest (based on surface turbidity)just after ice-melt in late May (0.26 m-1). While trends in temperature and sediment profile development ,were well documented by the bi-weekJy sampling trips,potential improvements remain regarding the field procedures employed in 1982.The following 2 - 1 improvements are recommended to enhance the continued Eklutna Lake field data efforts. Two and even three dimensional temperature gradients exist in the lake, and are subject to dynamic response to short-term meteorological effects. Continuous temperature monitoring such as has been attempted with·Ryan thermographs would demonstrate the time scale of the response of the lake to the driving forces of wind mixing and surface energy transfer. Installation of several sets of continuous monitors would improve the understanding of the effects of wind setup and subsequent seiching on the lake temperature regime. As for examining sediment dynamics in the lake,a more complete picture at each sampling date may be of benefit in describing suspended sediment loadings and gradients.Transmissivity profiling is valuable in that local turbid microstrata may be pinpointed with greater accuracy than is possible with retrieval of isolated samples for turbidity measurements. Verification of particle size and species of Eklutna Lake and Eklutna River sediments with corresponding particle analyses for the Susitna River sediments would enhance the value of comparison of the two watershed systems. ~.,~, 1.-' .-j' - ...., s5/y 2 - 2 3 -METHODOLOGY I n order to meet the objectives of the study as discussed above,the field data collection program at Eklutna Lake has included acquisition of: o o o o o o Weather data Lake inflow data La ke outflow data Light extinction data Lake temperature,conductivity,and turbidity profiles. Suspended sediment samples and analysis .....'" ~~~(', ;0.. 3.1 - 3.2 - s5/y Weather Data By special permission of the Chugach State Park,a weather station was established on June 3,1982,at the south end of the lake near an existing gravel airstrip (Figure 3.1).The weather station consists of a "Weather Wizard"monitoring system manufactured by Meteorology Research,Inc.The system measures air temperature, wind speed and direction,relative humidity,solar radiation,and precipitation.Temperature,relative humidity and radiation levels are recorded as instantaneous values every 15 minutes on a magnetic tape cassette.Wind data are processed from 15 second interval readings by the data logger and recorded as average winds and peak gust for each 15 minute interval.An attempt to measure incoming long wave radiation was begun by adding'an Eppley Laboratories Precision I nfrared Radiometer to the system in late July.Instantaneous values are recorded at fifteen minute intervals. Raw data from the tapes are edited and summarized in tables and graphs on a monthly basis.Monthly data summaries for June through November are included as an appendix to this report. Data were transferred to Acres American for use as model input after being transcribed and converted to apF'ropriate units by hand.Considerable interpretation was required to correct data gaps in July and August. La ke I nflow Data Principal inflow.into Eklutna Lake is provided by two creeks on the south end of the lake.The creeks,known as East Fork and Glacier Fork of Eklutna River,account for 31%and 22%, respectively,of the"la ke's II I square mile watershed area.The two creeks intertwine in braided channels on a broad floodplain before entering the lake.The streams were gaged separately,several miles from the lake head,as the first available usable sections for stream gaging were upstream of their confluence.Very little 3 - 1 ". groundwater flow is expected to augment the stream discharge downstream of the gaging sites. Stage discharge relationships were established for both streams. Stevens Type F water level recorders with 16-day charts were utilized to continuously"monitor stream discharge.The water level recorders were housed in plywood gage houses on 16"diameter polyethylene pipe stilling wells.The stilling wells were provided with U"diameter PVC inlet pipes which extended into the channel. I nflow temperatures were monitored with Ryan thermograph recording thermometers.These instruments were anchored to rocks placed in the stream such that the sensor would remain submerged. Originally,one thermograph was installed near the inlet to the lake.However,it was determined that this installation was biased in favor of the Glacier Fork.Thereafter,the stream temperatures were independently monitored at the gaging sites. Suspended sediment samples were obtained at each gaging site for sediment concentration and turbidity analysis.Sediment concentrations in the stream samples were determined by Chemical and Geological Laboratories of Alaska of Anchorage according to standard procedures for detection of Total Nonfiltrable"Residue. Turbidity analysis was done in the R&M laboratory using a Hach Model 16800 Portalab Turbidimeter. 3.3 -Lake Outflow Data The Eklutna Hydroelectric Plant,operated by the U.S.Dept.of Energy,Alaska Power Administration,keeps daily records of lake discharge through the turbines,and monitors penstock water temperatures through the course of each day.These data were made available to R&M for DYRESM input.The power plant personnel also make weekly measurements of lake level.These lake level observations were used in conjunction with R&M's own periodic lake level measurements as lake level/storage input data. ""'1~. I., 3.4 ~Light Extinction Light extinction is generally considered to be in the form of exponental decay according to the equation: Where I is irradiance,is irradiance at the water surface,y iss depth below the water surface,and "7 is an extinction coefficient. Measurement of irradiance below the water surface was possible using the LiCor Model L1 1925B Underwater Photometer.This 3 -2 :MlP ""'1 ..I ~._------------------------------------------------- instrument measures photosynthetic photon number of photons incident per unit time wavelengths comparable to the visible nanometers). fl ux density,or the on a un it su rface at spectrum (400-700 ,~, -r l 3.5 - Readout from the sensor is-via an analog meter in units of micro-Einsteins per square centimeter per second.(One Einstein equals approximately 6.022 x 10 23 photons.)Translation of photon units to the more common radiant energy units is complex and requires knowledge of the spectral distribution of the radiant output from the source.For daylight conditions,a linear approximation of the conversion to within ;;8.5%is given by the instrument manufacturer as: 1 watt/square meter =4.6 micro-Einsteins/square meter/second Secchi disk transparency measurement utilizing a 20 centimeter diameter weighted steel disk were made to provide back-up data to the light extinction measurements made with the photometer.The disk was painted with alternate glossy quadrants of black and white,to facilitate definition of the reflective disk surface when submerged. Water Quality Profiling Figure 3.1 shows the locations of fifteen lake stations spanning the surface area of the lake.The stations were marked with international red fluorescent buoys.A temperature profile was taken beneath the ice at the lower end of the lake on April 16, 1982.Bi-weekly sampling of lake temperatu re,conductivity, transmissivity and turbidity commenced on May 25,1982.The procedure involved lowering a temperature and conductivity probe from a 15'inflatable Zodiac raft at each of the fifteen station moorings.The number of stations sampled per trip was later reduced for logistical reasons.Early season measurements were performed using a YS I S-C-T meter with a 200-foot cable extension. I nadequate resolution of the instrument and electrical problems with the cable extension forced abandonment of that system in favor of a Martek Mark VII water quality sensor,beginning July 14,1982. The new instrument,with its LCD readout,improved the precision of the readings,but required vigilance in checking calibration. Recording thermometers were suspended in a string at one station to yield a continuous temperature record.However,the buoy system for the thermometer string was disturbed and the instruments are presumed lost to the lake bottom.No data have been recovered. Transmissivity was measured only once -on the June 17 and 18 sampling trip -using a Kahlsico No.269WA150 Turbidity Meter. While the information from transmissivity readings was useful for 3 -3 3.6 - s5/y yielding a complete profile of light attenuation in the lake's layers, problems with power connections to the instrument and depth limitations of its lOO-foot cable forced abandonment of transmissivity readings for the 1~82 season. Turbidity was measured at selected stations for each sampling trip from samples obtained at various depths using a brass Kemmerer type water sampler.The samples were analyzed on board the boat using a Hach Model 16800 Porta'lab portabJe turbidimeter.Duplicate readings from each sample were obtained to verify the results. Sediment Sampling and Analysis Certain samples subjected to turbidity analysis were retained for laboratory analysi's of suspended sediment concentration,particle size distribution,and mineralogical analysis,including density and species identification.Sediment concentration was determined by standard procedures for Total Nonfilterable Residue.Particle size distribution was performed using an Electric Zone Fence technique. Microprocessing involved in the technique allows direct computation of statistical parameters associated with the distribution.Density distributions were obtained by immersion in a methylene iodide/xylene gradient column.Visual observations and photomicrographs were utilized for mineral species identification. Lake sediment analysis was performed by Particle Data Laboratories, Inc.of Elmhurst,Illinois. In addition to the lake sampling,one sample from the Susitna River was subjected to similar analysis for particle size distribution, density distribution,and mineralogical analysis for comparison. 3 - 4 - - - - ,1 ,I ,\- - ...

LAKE LOCATIONS FIG.3.1 EKLUTNA STATION "- PREPARED BY I --------,----...,...----'------~----------- 4 -RESULTS AND DISCUSSION ..... 1 4.1 - s5/y Lake Temperature Temperature profiles from the lake sampling are shown in Figures 4.1 and 4.2 for May through November.These profiles reveal the annual cyclic change in the lake's temperature distribution.Near-isothermal conditions exist beneath the ice in April and at breakup in May.The development of a weak thermocline is seen by mid-June,and continues through July until the maximum s'urface temperature is achieved in August.The highest recorded·surface temperature was 14.88°C on August 25,1982.After this time,wind mixing and surface cooling combine to reduce the temperature stratification until the lake water column'is virtually isothermal by September 21.The lake then gradually cools isothermally with vigorous overturn taking place as water at the surface becomes denser due to convective,radiative, and evaporative ~ooling.The cooled water sin ks,to'be replaced at the surface by deeper,warmer water.Through the month of October the water column continues to slowly cool isothermally,with overturn continuing.By the first week in November,water temperatures are quite similar throughout the lake,with the overtu rn continuing as the waters have not reached maximum density at 4°C.The slow cooling is evidence of the large heat content of the lake.While Eklutna Lake was still above 4°C,most of the other lakes in the area had long since frozen. Temperature comparisons within the lake for selected dates are shown in the temperature isopleths (Figures 4.3 through 4.12.) Temperatu re variation along the longitudinal section is evident from several dates.The temperature isopleths are "snapshots"of the entire lake compiled from temperature data from the individual stations.The contour lines are drawn from linear interpolatron of data from the station.Stations from which data are taken for constructing the isopleth are indicated at the top of each figure. The lake temperatu re regime is dynamic and constantly chan-ging in three dimensions and with time.The isopleth maps reflect not only the general thermal condition of the lake but also short term effects of wind setup and internal seiching.Thus,individual "snapshots" a re not always composed of even 'strata of constant density.For instance,strong north winds on July 27 caused a pile-up of warm surface waters on the upper end of the lake,whereas south winds are probably responsible for the relatively warm surface waters on the lower end of the lake on September 9.Similarly,fluctuating meteorological conditions may be the chief factor behind the extreme fluctuations in profiles between stations on June 17/18 and on September 21.The complete upset of horizontal density layering is seen from the October and November isopleths during the fall overtu rn.I n these cases there exists only horizontal temperatu re gradients,based upon differential rates of cooling in various portions of the lake.The effects of wind driven circulation are 4 - 1 -------~--------------_.---~~--,....---- s5/y probably not as important here because of the breakdown in thermal stratification. A closer look at other aspects of water quality profiling is shown in the series of station plots shown in Figures 4.13 .through 4.23. Conductivity,turbidity,and,on one date,transmissivity profiles are shown for each station and date.The profiles are situated on the sheets in ascending station order,so that trends may be viewed in the course of water movement from the upper end of the lake (upper left)to lake outlet/hydropower intake (lower right). The first full set of profiles,from May 25,1982,demonstrate the condition of the lake just after breakup.Temperatures throughout the lake are close to 4°C,approximately the temperatures observed beneath the ice on April 16 (Appendix A).Turbidities are extremely low,generally less than 10 NTU,as a result of quiescent settling in winter.Conductivity profiles show moderate and nearly linear increases with depth. By June 17 and 18,surface warming has allowed development of a moderate temperature gradient in the upper five meters.The strength of the gradient varies from station to station due to the existing state of continual wind mixing,and to the strengthening of the gradient by interflow,which is the introduction of streamflow as a distinct density layer in the water column.The introduction via interflow of water from the creeks is evident at the upper end of the lake.The turbid inflow from the streams enters the lake at several strata,as evidenced by tongues of low transmissivity and corresponding increases in turbidity at several depths at stations 2, 4,and 8.The evidence of inflow has ceased by mid-lake (Station 9),where the steepness of the upper temperature gradient is markedly reduced.Almost no temperature gradient is evident at the lower end of the lake (Station 15),probably as a result of complete mixing in the shallow water column. The July 2 data suffers from electrical problems with the profiling instrumentation.All available data represent measurements made at the surface of water samples retrieved from various depths using the brass Kemmerer style sampler. By July 14,distinct trends in temperature stratification and interflow are apparent.In these profiles,a single turbid stratum of fresh inflow from the inlet stream is evident from both turbidity and conductivity profiles.Just beneath the steep thermocline there appears a marked reduction in conductivity and a sharp increase in turbidity.These occurrences are especiatly noteworthy near the lake head (Stations 2 and 4),where'the most well defined stratification exists with a thermocline layer at 8-10 meters depth. The turbid layer appears to run quite far down the lake basin. Highly turbid water at about 15 meters depth is evident as far down lake as Station 10.Variable levels of conductivity indicate 4 - 2 .... - "...., .l! .. ·/ l, ....., \ -' I' ,, ..... s5/y active mixing in the upper eighteen meters,especially on the lower end of the lake,away from the influence of the turbid water inflow. At the end of July the pattern of the previous sampling date is continued.A more distinct thermocline exists on the upper end of the lake,underlain by a broader and denser turbid layer. Turbidities at Station 2 are plotted as 100 NTU for depths of 12,16 and 20 meters.This value is the upper limit of the instrument range,and the actual value is likely be considerably higher; Evidence of the turbid layer has appeared in the lower basin with a peak tu rbidity at Station II of 35 NTU at 12 m depth. August 12 data indicate an even more well defined thermocline. The tu rbidity of the interflow layer appears to be dispersing. Highest turbidity readings from this date are under 90 NTU. August 25 data begin to reveal a weakening of the thermocline as solar heating diminishes and wind mixing begins to break down the thermal stratification.Correspondingly,turbidity values begin to drop off once again,due to dispersion and to the reduction in streamflow discha rge.' In September,inflow starts to taper off,both in terms of volume of water and level of stream tu rbidity.The lake su rface begins to undergo a net loss in su rface heat exchange.Su rface temperatu res drop and the stability of the water column decreases.Turbidity monitoring at Station 2 has indicated no fu rther interflow. Streamflow temperatures indicate that the interflow of July and August has been superceded by a diving underflow of dense influent water Deepwater tu rbidity measu rements were not sufficient to document this occurrence at Stations 2 and 4,but farther down the lake at Station 7,high levels of turbidity are exhibited at 48 meters depth.High levels of turbidity in the 20 to 24 meter depth at Stations 4,7,9 and 11 range are probably due to suspended sediment left over from the interflow of July'and August.Such tu rbidity peaks are associated with water temperatures near 7.SoC,while the turbid layer at 48 meters is associated with water temperatu res of about 6°. By lake September,the lake is approaching isothermal conditions at each station,with a tendency towa rd cooler water temperatu res on the upper end of the lake.The cooler isothermal temperatures on the upstream end are indicative of the larger volume of cold water below the thermocline depth in the upper end of the lake,and due to prevailing winds from the southeast forcing warmer surface water to the la ke's north end. The effects of turbid underflow are also apparent from the September 21 profiling,as peak turbidities close to 100 NTU are discovered at or near the lake bottom.Streamflows and stream sediment loads have tapered off somewhat from the associated 4 - 3 4.2 - mid-summer highs,but turbulence of the dense,cold underflow may be entraining bottom sediment to add to the tu rbidity found near the la ke bottom. October 14 data show isothermal profiles,with temperatures somewhat warmer at the upper stations.This is lIkely due to the slower cooling of the upper lake because of the larger volume to surface area ratio in the upper end.That the lake is actively overtu rning is suggested by the consistency of tu rbidity measurements throughout the lake.The uniform turbidity verifies the breakdown of stratification.In October,streamflow drops significantly (less than 205 cfs or 500,000 'cubic meters/day)and inlet water is running clear and cold (close to 0°),so the generation of any new distinct tu rbid layer is improbable. The last set of profiles on November 4 shows isothermal temperatures in a much narrower range,with colder temperatures evident in the lower lake shallow areas.Turbidity measurements are consistent for 3 station readings at the surfa"ce and at seven meter depth.It is expected that the active overturn process is maintaining -turbidity levels similar to the seven meter value throughout the water column.Surface values of turbidity are uni- formly 1 NTU less than the seven meter values.Conductivity is also a few umhos lower at the surface.This is possible evidence of clear,cold buoyant inflow and the addition of fresh snowfall which has not been mixed into the lake. Sediment Studies A significant portion of the efforts of the program were directed toward characterizing the behavior of sediments in the lake. Suspended sediment samples were taken from depths of peak turbidity and from other selected locations during most profiling trips.Samples were analyzed for gravimetric"sediment concentration and particle size.Sediment concentrations in the lake ranged from 0.1 mg/l from the uniformly turbid profile of October 14,to 63.5 mg/I from the peak of the turbid layer at Station 4 on July 28. As mentioned above in the discussion of temperatu re stratification, there are pronounced effects of sediment-rich interflow evident from the tu rbidity profiles.It is from the layer of maximum turbidity at Station 4 that the maximum sediment concentration of 63.5 mg/I was recorded. Turbidity and sediment concentration are compared in Figure 4.24 for both lake and stream measurements.The least square curve fit shown on the figure has a correlation coefficient of 1"2 =0.83.It may be inferred from the plot that most of the stream sediment load 4 - 4 .. - -}- t " ) ":10'- ..... ", ., ·. -F f ~, --, ~'. -s5/y is deposited in the delta at the lake head,and only reduced concentrations of sediment are carried into the lake. The lake sediment profiles of Figures 4.25 through 4.31 illustrate the distribution of concentrations of sediment and lake mean particle size. Particle size distribution are given in Figures 4.32 through 4.38. For the most part,suspended sediment particles averaged 3 to 4 microns in equivalent diameter.No relation could be drawn between particle size and lake depth,sediment concentration, turbidity,or station.Notable exceptions to this 3-4 micron trend occur at Station 11 from sampling trips on June 18 and July 15. These show extraordinarily high ranges of particle size,including mean particle equivalent diameter of up to 33 microns on the latter date. The principal source of sediment is the glacial inlet from East Fork and Glacier Fork.At peak inflow at the end of July,particles as large as 40 microns in·equivalent diameter were found at Station 6. Although particle size averaged to 4 microns the coarser portions of the size distribution varied from sample to sample.Typically fewer than 0.1%of the particles in any sample were larger than 25 to 30 microns. Three lake samples were analyzed to determine the relative density distribution of the minerals present.For comparison,Table 4.1 shows density distribution for one sample from the Susitna River. The densities are shown in the histogram of Figure 4.39. It appears from a comparison of the densities of the Eklutna and Susitna waters that a specific gravity of 2.8 is an appropriate mean density for the sediment particles of the waters. I n addition to identifying mineral species and densities,th~shapes of the particles of lake sediment are also important in determining settling characteristics.Particle shape also affects turbidity. Metal-shadowed photomicrographs of suspended sediment were made at 400 x magnification to get a qualitative evaluation of the suspended material.Figure 4.40 shows typical photomicrographs. It appears from the figure that typical sediment particles are flaky and quite angular.The shape of the particles,therefore,are effective in increasing turbidity and reducing sediment fall velocities due to the increased turbulence and viscous effects of the surface area of the particles. Minerological analysis and photomicrographs of the Station 11, July 15 sample were utilized to account for the large particle sizes discussed above.Photographs demonstrated that the particles were sphereulitic concretions of calcium carbonate in the form of crystal aragonite.These photographs are shown in Figure 4.41.The 4 - 5 4.3 - occurrence of this mineral at only Station 11 is puzz:ting.One explanation would be the introduction via springs of hard groundwater which causes precipitation of calcium carbonate in the water near Station 11.Turbulent mixing in the water column prevents deposition of the precipitate,and the crystals grow while circulating in the hard,calcium saturated'waters.No water chemistry was provided for in this study,so the lake hardness has not been documented. A petrographic analysis was conducted on the four samples via polarized light microscopy to determine the relative quantities of the various mineral present.All microscope observations and density determinations were conducted by Mr.M.Bayard of Particle Data Laboratories. light Extinction Data collected with the liCor underwater photometer are summarized in Tables 4.3,4.4 and 4.5 and plotted in Figure 4.42 through 4.44. The semi log plots of the figu res demonstrate exponential decay of the photon flux density (or irradiance)with increasing depth. Extinction coefficients (~)based on least square curve-fitting techniques for the exponential decay are given in Column 3 of Table 4.6.Coefficients vary from 1.08 to 2.35. Correlation coefficients (r2 )for the least square linear approximations range from 0.95 to 0.99 as shown in Column 4 of Table 4.~.There is fai r agreement between extinction coefficients from different stations for a given date.Seasonal variation is readily apparent.The principal factors .affecting the seasonal variation are the formation and subsequent deterioration by mixing of density strata in the lake,and variation of the suspended solids concentration in inflow.I nflow and corresponding suspended sediment loading of the lake are at a peak in early August,after which time the surface·light penetration increases until October when the fall overturn.creates a uniformly turbid water column. In several data sets,the effects of layering are apparent.The plots on Figure 4.42 for Stations 4 and 7 of July 27,for example, show different rates of extinction above and below the 1 meter depth. Also shown on the table are values for secchi disk transparency and inverted secchi disk transparency,of which the latter has units equivalent to extinction coefficient. Figu re 4.45 compa res the inverted secchi disk transparencies from Column 6 of Table 4.6 to the extinction coefficients derived from the photometer data in Column 3.It seems that for the range of 4 - 6 -"• ~ ~ """t: ~< t ~ ~ ..~.~. jI .If· -.... 1 I r l light extinction in the glacial lake waters,the secchi disk does an extremely good job of estimating tight extinction. Turbidity values for the surface layers of Eklutna Lake are shown on Table 4.6 and plotted versus extinction coefficients in Figure 4.46.A correlation .coefficient of r 2 =0.964 for the linear approximation indicates that turbidity and extindion are closely correlated.It would seem that scattering by su.spended particulates appears to be the.gove1rning factor in light extinction in Eklutna Lake. Transmissivity profile measu rements were made on one sampl i ng trip only (June 17-18),using a Kahlsico No.269WA150 Turbidity Meter. Transmissivity readings versus Hach Tu rbidimeter readi ngs are plotted in Figure 4.47.The inverse relationship between the two parameters is clear,and the available data yield a fair correlation (r2 =0.63).However,the lack of additional sampling dates and the somewhat limited range of turbidities and transmissivities indicated fail to demonstrate clearly the relative effects of absorption versus scattering on light penetration or extinction. Practical use of the inexpensive secchi disk was shown to be a good indicator of a light extinction coefficient.Similarly,su rface turbidity measurements appear to be adequately correlated to extinction coefficients.The reliability of the second relationship seems to indicate that light extinction in lakes ladened with suspended glacial sediment is dominated by scattering rather than light absorption phenomenon.Fu rther analysis and an expansion of the transmissivity data base are probably required before this conclusion can be effectively upheld. Seasonal variation in light ~xtinction is extreme in Eklutna Lake, with measured decay coefficients varying from lows of 1.1m -1 in July and September to a pea kin August of 2.3m -1 Uti Iizing the correlation developed in Figure 4.47 between surface turbidity and extinction coefficient,light exti nction may be estimated for the ea ly season as well.Thus,the measured low turbidity value of I)~5 TU of May 25 wou Id correspond·to an extinction coefficient of CO.26 -1,an order of magnitude different from the maximum en"ion coefficient measured in August.Vertical mixing of turbid strata during the fall overturn cause the surface turbidity and light extinction to again increase in October. 4 - 7 ,. ~' f TABLE 4.1 DENSITY DISTRI BUTIONS ..- t f"""'( L -- Sample Eklutna Lake 2 July 82,STA 8,45M Eklutna Lake 2 July 82,STA 8,5M Eklutna Lake 12 July 82,STA 8,15M Susitna River Depth Integrated 4 - 8 Compos ition Density Percentage Range 80%2.80 -2.84 10%2.90 10%2.48 -2.55 70%2.85 -2.90 15%2.90 -3.05 15%2.65 -2.85 70%2.74 -2.80 25%2.74 5%2.8 -3.0 60%2.7 -2.9 15%2.9 -3.2 25%2.6-2.7 JI' t. ~r L " ~.
