Climate data from Talkeetna were provided by the National Weather Service with preliminary data for April and May 1982 supplied by the Arctic Environmental Information and Data Center. George Clagett of the Soil Conservation Service assisted in snow measurements and the resultant data interpretation. Jerry Nibler of the National Weather Service, River Forecast Center provided Talkeetna River water temperature data, historical Susitna River ice thickness data, river breakup predictions and valuable insight to specific erosion problems and ice jam formations near Talkeetna. Obie Weeks, Chief Engineer of the Alaska Railroad, contributed photographs of the 1982 flooding damage to the tracks near Chase, and Harold Larson, section foreman at Gold Creek, assisted with descriptions of major breakup events spanni'l9 the last ten years. Photog r·aphs of ice processes and documentation of field observations are a cumulative effort of the R&M Hydrology Staff: Steve Bredthauer, Jeff Coffin, Lisa Fotherby, Bob Butera and Carl Schoch. The interpretations presented in this report are based upon field observations, meteorologic data and published liter·ature. This report was authored by Carl Schoch, edited by Steve Bredthauer and typed by Joyce Shuman. -vi - • 1 -INTRODUCTION This report summarizes the field work. and presents the data collected on ice observations during the 1981-82 v,< nter season. This effort is related to the continuing feasibility studies ·for the proposed Susitna Hydroelectric Project. Initial ice studies began in 1980 with a comprehensive program designed to define the winter ice regime on the Susitna River. As the study progressed it became apparent that an understanding of the ice processes beyond a rudimentary stage would require more than one season of observations The ice studies program was continued through the winter of 1981-82 but on a reduced scale. Results of this latest program will supplement existing data from the 1980-81 Ice Observations Report (R&M) and further define ice formation and winter characteristics of the Susitna River. Conclusions based on these reports will help determine what modifications will be nece~sary during project development and design to mitigate any detrimental effects of regulated flow to areas downstream of the proposed damsite. 1.1 -Objectives The objectives of the 1981-82 ice study program were to compile data necessary for further analysis of the Susitna River ice regime. These data include: 1. Meteorologic data, primarily air temperature and precipitation, from stations at representative sites along the river. 2. Qualitative documentation of the ice processes during aerial reconnaisance flights and observations from shore. 3. Identify locations of frazil ice generation, accumulation, ice jamming and border ice bridging. 4. Hydrologic information on stage, discharge and velocities at critical areas. 5. Site-specific ice thickness measurements, determination of the overall extent of ice coverage and locations of open water leads. 6. Water temperature measurements from first frazil ice observations to formation of an ice cover. 1.2 -Report Contents The summary in Section 2 provides a brief overview of ice events and the factors controlling the 1ce regime through the 1981-82 s16/f 1 - 1 • winter season. Section 3 contains the compiled and summarized meteorologic data from four weather stations located within two miles of the r-iver. Graphic analyses are included to facilitate comparison of 1981-82 data with 1980-81 data and any historic records. Snow course data from the Soil Conservation Service constitute Section 4, along with a discussion summarizing the significance of this yt:!ar's snowpack relative to ice formation and destruction. Section 5 discusse5 ice processes relative to the Susitna, incorporating information from field notes, aerial photographs, surveys, interviews and visual observations. The Alaska Rail road experienced problems during this year's abnormally severe break- up. These sections of track are described and documented with photographs of the damaged track. Attachment A contains the monthly climate data printouts from the National Weather Service and R&M Consultants for the stations described in Section 3. Attachment B contains the available streamgage records from U.S.G.S Stations at Denali, near Cantwell (Vee Canyon), Gold Creek and Susitna Station. Also included are the final 1981 records of the R&M streamgage station at Watana. These records indicate the dates of first ice occurrence at each site. No stream- gages were in operation during breakup. Attachment C is a tabulation of National Weather Service, River Forecast Center, stage and water temperature data collected on the Talkeetna River at Talkeetna. Appendix D presents an inventory and index of oblique aerial photographs of ice formation. The field notes of aerial reconnaissance f:ights are contained in Attachment E for 1981-82 and Attachment F for 1980-81. Finally Attachment G presents a tabulation of ice thicknesss from Trapper's Creek, Alaska (near Talkeetna). s16/f 1 - 2 2 -SUMMARY The 1981 freezeup process was prolonged by the lack of any early cold, weather episodes, in contrast to 1980 when a November cold snap caused significant ice formation. September 28, 1981 marked the first day of observed frazil and ice pans on the Susitna. Fluctuating air temperatures and relatively heavy precipitation through October precluded the formation of a stable ice cover. Air temperatures were on a gradu~l decline closely resembling the graphical plot of historical averas ~s. However, the precipitation record is far from normal with an extremely large volume of pre- cipitation in October and sharply decreasing amounts through January, when scarcely any precipitation was recorded. This same general trend shows up in all of the selected climate station summaries. By the second week of December the leading edge of ice on the lower river was just approaching the town of Talkeetna, about two weeks later than in 1980. Long before the leading edge passed Talkeetna, however, an ice bridge formed at the Susitna- Chulitna confluence, and the ice cover progressed upstream from there. The Susitna is by far the most significant ice producer of the three rivers in the Talkeetna area. Whether due to cold temperatures, influences of higher latitude and elevation or the greater velocities and turbulence encountered through De vi I Canyon, the Susitna characteristically will show bank to bank ice slush coverage while the Chulitna and Talkeetna show only 10- 15 percent a real coverage. Therefore, when the ice bridge formed at the Susitna-Chulitna confluence, a barrier was presented to ice floes, drastically ~reducing the volume of ice feeding the down- stream ice pack. Consequently, it took almost 6 weeks for the confluence area between Talkeetna and the ice bridge on the Susitna to develop an ice cover. Anchor ice was first observed at the end of November in the Chase area, which could indicate a reach favorable to supercooling of ~vater. The water depth was estimated at 4-5 feet and with a flow of low velocity. No physical measurements were made but the ice deposits appeared to be thick with an unusual dark yellow or brown color. The rate of ice cover progression increased during January as minimum winter air temperatures were reached. Ice shelves were formed near the proposed Devil Canyon damsite in again 1981-82. However by January these had eroded open to expose a 30-40 foot wide channel which r·emained ice free for the remainder of the winter. The river reach from the Devil Creek confluence to the Fog Creek confluence res is ted freezing over until March, but even then the ice cover was marked by extensive overflows. Breakup was more dramatic this year than in years previous, as demonstrated by extensive erosion and by damage to the Alaska Railroad tracks. Air temperatures increased during the second s16/c 2 - 1 half of April but nighttime lows still dipped below 0°C. By May 7 even minimum daily temperatures averaged 4°C and ice movement began. Jams occurred in most of the areas described for 1981 but with gr·eater consequences, ranging from scarring and denuding of vegetation to flooding and washing away railroad ties from under the tracks. In several areas below Talkeetna massive amounts of soil were removed from cutbanks, jeopardizing at least one residence. In the vicinity of the Watana Damsite, breakup effects were not as dramatic, with more melting in place and less erosion. The jam just downstream of the mouth of Watana Creek caused total channel blockage and ice accumulations for 1 mile upstream. The only other significant jamming observed in the upper river took place near the mouth of Jay Creek. This jam backed up ice floes and impounded water for several miles. However, since the channel here is confined, no significant flooding took place. Heavy accumulations of snowfall 1n November created an above normal snowpack for December. Precipitation was very light through December and January, resulting in a February snowp.ack in the Upper Susitna Basin 15 ... 20 percent below normal. In March, additional snowfall brought levels back up to 90 percent of normal. Increasing air temperatures in April and May created substantial runoff with subs~quent increases in river stage, leading to ice cover fracturing and breakup. In general, the air temperatures this past winter were near normal. Therefore, the unique characteristics of r·iver morphology and how they effect the ice regime were emphasized. In contrast, the winter of 1980-8'1 (R&M, lee Observations Report, August 1981) had fluctuating air temperatures which resulted in unusual ice phenomena during freezeup and breakup, which should not be considered as normal. Therefore, rivet'" reaches which showed ice bridges, frazil generation and anchor ice formations during 1981-82 warrant special attention and further study to determine how these areas will be affected by regulated flow and relatively higher water temperatures induced by post-project releases. s16/c 2 - 2 3 -CLIMATE The climate summaries presented in this report constitute temperature and precipitation data monitored at selected stations in the immediate vicinity of the Upper Susitna River between Talkeetna and the Denali Highway. Data from other weather stations both on the project (R&M) and in the surrounding area (NWS) have been omitted since they are of questionable value due to the large variations in weather patterns away from the river valley. Four stations were selected to best represent the climate directly affecting the river freezeup and breakup processes. The National Weather Service (NWS) station at Talkeetna Airport provides a 41-year record of temperature and precipitation. This record provides the baseline data for control purposes and correlation with R&M weather stations having less extensive records. With its proximity to the Susitna confluence, the Talkeetna station data provides useful input to studies attempting to determine ice effects and processes d!J ring post-project flow. The Devil Canyon climate station, located near the proposed Devil Canyon damsite, provides representative climate data for the Gold Creek to Devil Creek area. The Watana Camp station, situated on the norther·n bench above the proposed Watana damsite records temperature and precipitation data which correspond to the river valley between Devil Creek and Mt. Watana. The Denali station, located at Susitna Lodge, represents weather patterns affecting the eastern p(;!rimeter of the project as well as the extreme upper river basin. These three stations are operated by R&M Consultants and have provided data since 1980. The geographic locations of these four weather stations are depicted on Figure 3. 1. Table 3.1 lists temperature and precipitation data obtained during the 1981-1982 winter, October through May, from the four weather stations described. These values can be compared to the 1980-1981 winter record on Table 3.2. Figure 3.2 shows a National Weathe~ Service summary of the 40-year average winter temperature and precipitation values from the Talkeetna station. Although additional meteorologic information is available from these weather stations, the compiled data in this section only include average monthly temperature, m1n1mum monthly temperature, maximum monthly temperature, total precipitation (water equivalent) and total monthly snowfall. For any subsequent intensive study effort requiring detailed meteorologic data the complete published National Weather Service and R&M Consultants climate summaries should be consulted. The historic Talkeetna temperature records of 40 years are shown in comparison to the Talkeetna 1981-1982 data in Figure 3.3. s16/i 3 - 1 • To facilitate comparisons at a glance, Figures 3.4 to 3. 7 provide graphical illustrations of average monthly temperature fluctuations during the 1981-1982 winter relative to the 1980-1981 winter. Figure 3.8 compares the historical Talkneetna winter precipitation to the 1981-82 precipitation.

TOTAL ~REC2PITATION,i 4 -SNOW The snowfall and water content data obtained from snow course surveys is beneficial in monitoring winter precipitation and in predicting spring runoff, with applications in forecasting river ice breakup. With the cooperation of the Soil Conservation Service, the following snowfall, snowpack and water content data have been compiled. Early December snowpack was significantly above normal in south- central Alaska, with the majority· of the accumulation occurring during the Thanksgiving storms. Precipitation was very light for the remainder of the year with the exception of the Talkeetna Range, where snowfall set a maximum record for an 18 year period. South central Alaska received little additional snow. The snowpack in the Upper Susitna Basin in January was generally 15 to 20 percent below normal, and as much as 50 percent below normal in areas of the lower basin. However, the· snow was unusually dense, with a high water content. During February the eastern ae--eas of the Susitna Basin showed a snowpack increase but still remained 20 percent below normal. The sncw survey in March revealed a snowpack over most of the Susitna Basin of 10 percent below average with minimal additional precipitation occurring m April. The Oshetna drainage received substantial amounts of runoff stemming from the record snowfalls in the Talkeetna Range. These higher stages may have contributed to the unusually dramatic breakup of the upper Susitna in the vicinity of Jay Creek. The snow pack data obtained from the Soil Conservation Service are reproduced in Figure 4.1. Snow course data from the three R&M climate stations described in this report are shown on Table 4. 1. It should be noted that the snow courses at Watana and Denali tend to be windblown and may not accurately represent snow depths for a large area. s16/j 4 - 1 I.

J 5 -ICE The following is a general description of events recorded during the ice formation and disintegration processes on the Susitna River. Most of the ice phenomena were observed during aerial reconnaissance flights and identified by river mile (RM) locations. Refer to Attachment E or the R&M Susitna River Hydrographic Maps for orientation. 5.1 -Ice Formation General Observation: Individual crystals of ice called "frazi!" are generated in the colder turbulent river reaches such as Vee Canyon, Watana and especially Devil Canyon. With air temperatures near -10.0°C the upper layer of water in these areas becomes supercooled and small frazil ice crystals are formed. If the water is well mixed, then a tremendous number of these crystals are generated. Upon entering slow water, they tend to consolidate at the surface and can develop a sufficient thickness to emerge and drain. Encounter·ing another section of rapid water these ice pans or sheets are ~rushed, broken and re-emerge as masses of individual crystals, usuai!y only a few inches in diameter. Entering slower water, this frazil slush will again agglomerate and form ice sheets which proceed downstream as long ribbons of individual pans measuring 2-3 feet in diameter. Entering Devil Canyon beyond the Dsvil Creek confluence, these ribbons of ice pans a.re broken up and mixed with water and additional frazil to form a slurry which, due to the turbulent nature of the canyon has no chance to surface. Nearing Portage Creek the velocities slow and a more laminar flow resumes, causing the emerging mass of slush and frazil from the canyon to fot .. m ice rafts. The size of these rafts depends on the nature of their movement and con- centration. As the rafts flow downstream they tend to rotate and collide with border tce and other rafts, which breaks them up into smaller plates. In October, when air temperatures began to fall below 0°C at night, water temper~atures also gradually fell to the freezing point and drift ice appeared on the surface. Sheet ice appear·ed over areas of slack water and frazil ice formed in the more turbulent sections. Anchor ice grew in rather shallow (4-5 feet) but fast water. Slush ice -floes formed under certain conditions and due to the fast current of the river, these ice floes were carried down- stream and came to rest at sections of diminished velocity. Converging border ice and low velocities of water combin( ... cl to form ice bridges from which the ice pack progressed upstream by accumulating floes at the leading edge. An ice cover over the entire water surface proceeded up to the foot of a rapids section, which was usually also a frazil ice genergtot". The ice continued to s16/a 5 - 1 pack up against the leading edge, ~' entually causing an increase in stage upstream which in turn led to decreased velocities and turbulence of the rapids, allowing further ice progression up- stream, but at a slower rate due to the elimination of an ice generator. Ice covers were observed to form over the two most turbulent rapids in the river, at Devil Canyon and Watana, while river reaches above and below these rapids sections remained open. This may be explained by the unique combination of thermal and hydraulic factors controlling these areas, specifically, a cold climate causing continuous cooling of the water, combined with water velocities greater than those critical to ice formation. An ice cover would not normally develop under these conditions (Newbury, 1969). Tremendous quantities of frazil and slush, however, are produced and emerge from these ice generators. Assuming the presence of a relatively calm plunge pool below these rapids, a border ~ce formation will develop. As these ice shelves converge the remaining open channel would be quickly clogged by drifting ice. Continuous input of large masses of slush and frazil would be deposited underneath this ice cover. Together with anchor ice deposits on the river bottom the channel would become more constricted leading to rises in water level. The impounded water would actu~llly be a slurry of slush ice and could attain depths of 14-17 feet, as plotted on the Map and Profile of Devil Canyon in the back envelope. When the flow of the impounded water has decreased to the critical velocity for the accumulation of ice, the leading edge will progress through the rapids. Simultaneously the slurry of slush ice in the pool would quickly freeze solid resulting in an immensely thick but incompetent ice cover. The thickness of the layer is naturally the same as the f''ise in stage which is controlled by the river gradient and the degree of stability required before ice progression resumes. Therefore, the steeper the river gradient, the thicker the resultant ice cover development. This is verified by the data presented in the R&M report "Preliminary Channel Geometry, Velocity and Water Level Data for the Susitn~ River at Devil Canyon," April 22, 1981. The ice thicknesses measured were greatest over the steeper gradient sections of the canyon. These ice covers over rapids section, during final stages of ice formation will eventually erode open after the accumulated ice cover has passed through the reach. As will be described later in this section, these rapids generally remain open throughout the winter but characteristically show immense layers of ice on both banks with vertically sheared edges constricting flow to a narrow channel. The relatively weak nature of these shelves causes them to deteriorate by a process of calving. Fractures develop through the shelf and huge blocks periodically fall into the channel and drift downstream. A similar phenomena was documented by Newbury in "The Nelson River: A Study of Subarctic River Processes", (1969). s16/a 5 - 2 5.2 -Chronological Field Observation, Freezeup September 28, 1981 -Frazil ice was first seen by R&M personnel at Go!d Creek. Alaska Department of Fish and Game field crews experienced outboard motor problems due to ice intake. October 2, 1981 -Frazil ice was first observed at river mile 110 during a morning flight up the Susitna River on October 2~ 1981. A nighttime low temperatu r·e of -7. 5°C was recorded at the Devii Canyon station. The weather stations further upstream also r·ecorded temperatures well below 0°C. No frazil ice was observed in the confluence area. The air temperatures upstream of Talkeetna were apparently cold enough to allow supercooling of the top layer of water, creating conditions suitable for frazil generation in several areas. Increasing concentrations of frazil ice were observed upstream of RM 119, along with ice pans forming in river reaches of lower velocities. The shallow side channels showed bor""der ice forming characteristically on the left or south- east bank only. This indicates that solar radiation may have been warming the water and the north bank sufficiently to prevent shore ice formation. The downstream end of the rapid water section above Curry was extruding a large amount of frazil and slush. Ice pans 2-3 feet in diameter were seen above Gold Creek, with the concentration progressively increasing in density nearer to Devil Canyon. At Portage Creek, the pans extended con- tinuously across the channel. Through the canyon no ice was seen on the surface but the unusual light green shade of water throughout this t·each indicated a high density of slush ice through the water column. Floating ice pans were again noticed above the Devil Cr·eek confluence and extended upstream beyond the Deadman Creek confluence area, where tee pans formed an almost continuous layer across the channel. See Figure 5. 1. The discharge at Watana streamgage was 5,900 cfs. October 6, 1981 -In contrast to the first reconnaissance flight, aimost no frazil or flowing ice of any form was observed. The low temperature during the previous night was -4.2°C at Watana and -2.0°C at Devil Canyon. Apparently no frazil ice was being generated. Border ice growth continued in several sections of slower moving water upstream of Devil Canyon. October 29, 1981 -With air temperatures fluctuating above and below 0°C all through October, no permanent ice formations developed. Between October 12-15, temperatures increased sufficiently to melt much of the remaining border ice. Therefore, no further flights were scheduled until a predictable weather pattern developed. By the end of October, air temperatures at all four weather stations were gradually decreasing. Observations were made up to river mile 115 only, due to poor flying conditions. The previous night low temperature was -9.4°C. In the Chase vicinity concentrations of ice pans of 2~3 feet in diameter were often seen extending from bank to bank. Border s16/a 5 - 3 • tce was agatn building along both sides of the river, and most sloughs and side channels showed a continuous ice cover. Ice pans and rafts from the Susitna formed 70 percent of the total floating ice below the confluence with the Chulitna River. November 2, 1981 -Temperatures had r·emained consistently low for several days, with an average temperature of -11.0°C. Above the mouth of Deadman Creek, the borde'~-~ ice had sufficiently extended into the channel to close the channel and form an ice bridge. Ice pans were accumulating against this obstruction, causing upstream growth of the ice cover, Another channel closure was forming just downstream of Bear· Creek confluence, about 1 mile below Tsusena Creek. An extensive ice bridge had developed below Fog Creek confluence but was not progressing further than the rapids section immediately below the Fog Creek confluence. A continuous ice cover had formed over the two mile long rapids section below the Devil Creek confluence, in the process previously described. Many ice bridges were building between RM 155 and RM 160. Devil Canyon had a continuous ice cover from the "elbow" down to RM 150. The discharge at Gold Creek at the time of these observations was 4,100 cfs. Below Gold Creek, the river channel remained open but thick sheets of con- solidated slush ice covered most of the channel. These ice rafts were periodically broken up and reformed by local variations in flow. As these slush ice rafts continued to move down channel, more ice was generated on the surface and within rapids. The increased ice concentration assisted the consolidation process by thickening and strengthening the ice rafts. At RM 115 channel constrictions concentrated the ice rafts, and bridging seemed imminent. Below l.h~se, the ice rafts were almost continuous. The individual rafts averaged about 20 feet across as they entered the Susitna-Chulitna confluence area. See Figure 5.2. November 6, 1981 Cold air temperatures persisted, and the follc.Jwing aerial observations were recorded. Below Talkeetna, the Susitna was ice covered from Cook Inlet to approximately Kashwitna Creek. The channel at the Parks Highway Bridge was choked with slush ice rafts. The confluence area showed some frazil ice being contributed by the Chulitna and Talkeetna Rivers, but most of the ice was drifting down from the Susitna. See Figu~·e 5.3. In the Chase area 50-60 percent of the river channel was covered by border ice. The re!T'aining oper. water contained 70 -90 percent slush rafts and frazil ice. An apparently stable ice bridge had formed at RM 105.5. Slush ice rafts were accumulat ... ing against it, creating an upstream pr•ogression of ice coverage. More ice bt-idge formatic.ns were observed at RM 123, RM 131 at Sherman, at RM 136 below Gold Creek, RM 145 and at RM 149 just above the Portage Creek confluence. The ice cover and bridges through Devil Canyon remained stable with no significant growth s16/a 5 "' 4 observed. No further ice formation was reported in the reach from Devil Canyon to Watana. This lack of ice formation may be attributed to the ice covered rapids and frazil generators up- stream. November 18, 1981 -The air temperatures continued to decline, ranging from -13°C at Talkeetna to -16.0°C at Watana. The leading edge of the ice cover had progressed upstream to within 4 miles of the Parks Highway Bridge. The open water was only 50 feet wide on the main channel at the bridge due to the steady growth of border ice. The Chulitna River showed increasing ice formation activity, with moderate concentrations of frazil ic~ and ever widening border ice. The Talkeetna River was completely !ce covered. The slush ice rafts previously observed on the Susitna River had consolidated and j9mmed at a border ice constriction at the confluence. A narrow channel of 50 feet in width remained open and showed ver·y dense slush and frazil ice. At RM 108, dense concentrations of anchor ice could be seen. Slush ice had bridged the open channel at RM 110 and a border ice constriction at RM 111 created a bottleneck restrict:ng the flow of ice rafts. The reach between Curry and Sherman was characterized by extensive anchor ice, giving the water a milky appearance. The ice bridge below Gold Creek remained stable, with no ice pro- gression. No further ice formation had occu red above the Devil Canyon area. December 14, 1981 -The ice cover had progressed to RM 95 below Talkeetna. From there to the Susitna-Chulitna confluence, the river· maintained an open channel. At the confluence, ice cover resumed on the Susitna River and Cl)ntinued to RM 127 with the exception of narrow open leads of varying lengths, usually less than one-half mile long. The open channel above RM 127 was 40-50 feet wide, and cont:dned 70 percent frazil ice. Extensive patches of anchor ice were also obser·ved. At Gold Creek the channel was 60-70 feet wide with no visible frazil ice. The ice covered reaches in Devil Canyon and below Devil Creek confluence had developed narrow open leads about one-half and 1 mile long, respectively. Above Devil Creek, the river remained open with extensive .border ice formations constricting the remaining open water. Ice progression seemed to have stopped above Devil Creek and border ice growth appeared to be the only development. January 4., 19f,2 Air temperatures remained consistently cold through Decen1ber averaging -12.6°C at Devil Canyon and Watana and -11. 7°C at Talkeetna. The Talkeetna, Chulitna and Susitna rivers were frc.,zen at the confluences with the exception of open leads resulting from either high ~;:rater velocities or groundwater intrusions. See Figure 5.4. The Susitna above the confluence was generally ice covered, with many reaches of narrow open leads. Near Sherman at RM 127, an open channel about 1 mile long persisted. Abo "e Sherman., the open leads became more numerous and generally longer. Above Gold Creek, the river was s16/a 5 - 5 • open but had many ice bridges. Little had changed through the Devil Canyon reach and further upstream. March 10, 1982 The lowest temperatures of the season were recorded in January, with a generai warming through February and March. A reconnaissance flight revealed that the Susitna River was entirely frozen from Talkeetna to Devil Canyon with only a few areas of open leads. See Figure 5.5. Areas showing overflow were becoming more frequent through out the reach from Talkeetna to Denali. Plates 1 through 7 in Appendix E present descriptions of ice formations as documented during the reconnaissance flights. These notes provide additional insight to ice formations in specific river reaches. 5.3 -Ice Breakup, General Observations The ice disintegration process on northern rivers is cha•ac'tdristically related to an increased discharge resulting from greater solar radiation in·~luence and subsequent melting of the watershed snowpack. Meltwater trickles down the banks and tends to pool along the sides of the channel. Narrow leads of open water develop along the edge of the shorefast ice. Increasing air temperatures and precipitation create marked increases in runoff contributing to the existing river flow, causing pressure to be exerted on the ice cover. Once critical stresses are exceeded in the ice cover, shore cracks develop and the decaying ice splits into numerious large rafts. In areas of high velocity~ the water will actually be forced through surface cracks, resulting in flow over the ice cover. Any remaining snow cover on the ice is quickly eroded and the weakening ice becomes candled. The ice at this stage is undergoing a process of deterioration called "candling". lmpurities in the water are rejected during crystallization and tend to be concentrated on the vertical crystal boundaries. The vertic.~al crystal structure is revealed at breakup by accelerated meltin~l in the columns of impurities between crystals. The ice cover as a result weakens, fractures and down- stream ice movement begins, (Newbury, 1969). The downstream movember of ice was at first sporadic and slow, as some sections of the ice cover remained shorefast or anchored in shallow reaches. Downstream movement accelerated until jamming occurred at natural constrictions and sharp bends. At this point of ice movement, the river was subdivided by a series of ice barriers which had formed during freeze up, as ice bridges. Drifting ice blocks acted against these barriers. High velocities caused them to submerge under the ice covering the deeper channel. The friction of bed material and surface ice may restrict s16/a 5 - 6 the passage of some ice blocks, and additional floes will Qccumulate upstream. With the flow constricted, the water level upstream will rise. If the jam can resist such pressure, the water continues to rise until it overflows into an existing side channel or creates a new channel, (Pariset, 1966), (Newbury, 1969), Although the latter event is rare in the relatively confined channel of the Susitna, the slough below the Gold Creek Bridge provides an example. Figure 5.9 shews a section of the U.S.G.S. topographic map, D-6, Talkeetna Mountains Quadrangle. Below the Gold Creek railroad bridge on the left bank there now exists a secondary overflow channel (Slough 11) which is not on the U.S.G.S. map published in 1951. This relatively new channel approximately follows the base of the terrace at the 700-foot contour line. The exact date of this event could not be provided by the Alaska Railroad or the National Weather Service. The jam which created this channel re-occurs almost every year very close to LRX-43 below Gold Creek Bridge. On going slough surveys (during the summer of 1982) will determine whether Slough 11 is also Hooded during peak summer flows or only as a result of ice jam flooding. The presence of an unusually high berm at the head of this Slough indicates flooding at only the most extreme main channel stages. Ice jams remain stable until increasing pressure from upstream ice accumulations and impounded water weaken and lift the ice barrier. The release t;auses a sur'ge of ice, water and debris to rush down- stream, often driving large ice blocks far from the normal channel, scarring shoreline vegetation and creating a "trim" line. The principal effects of river ice breakup 3re summarized by Newbury (1969): 1. An annual cycle of bed erosion and infilling occurs where unconsolidated material was present in zones of ice accumu Jation. 2. Bank and bed material of a size greater than that <;,:orresponding to the hydraulic competency of the river were striated and shifted downstream in local zones of ice cover movement. 3. A vegetation trim line was developed along the channel boundaries corresponding to the maximum ice level. 4. Local sections of terraces and braiding were developed by flow shHts in rapids zones during the annual period of ice accumulation. The 1982 bre ,~up on the Susitna occurred from May 10 through the 15th, very cl•)se to previously recorded breakup dates (R&M s16/a 5 - 7 .. Consultants, Inc. 1981). Field observations covering the breakup period began on April 12 to determine the general ice regime before deterioration began. The average air temperature through Apr·il ranged from 0°C at Talkeetna to -6°C at Denali. Table 5.1 tabulates the snow depths and water content prior to breakup. 5.4-Chronological Field Observations, Breakup April 12, 1982 -The river ice in the Chase area was snow- covered, with narrow leads showing no change in size since the previous reconnaisance flight. A continuous ice cover general!y extended to Gold Creek, with leads becoming more prevalent towards Portage Creek. Devil Canyon was entirely open from the proposed damsite to Devil Creek, with the exceptio!l of the same ice bridges reported all winter. At Devil Creek, the continuous ice cover resumed and extended to the Watana Creek conflu~nce. Occasional open leads had persisted all winter through this reach. No significant changes were observed since the March 10th flight. April 26, 1982 -The river below Talkeetna remained ice covered, with many areas showing overflow. South of Bell Island, however the ice had gone out, and the river was open. The Talkeetna River was still frozen, with open leads beginning to extend and connect. Heavy overflows were observed near Chase, indi~ating some localized runoff. Open leads dominated side channels and some sloughs which were influenced by seeping groundwater. With the exception of high velocity reaches the ice cover remained stable and continuous from Sherman to Gold Creek. in rapids zones, usually marked by open water leads, ice rafts were break- ing away from the ice cover and drifting downstream. From Gold Creek to Indian River the Susitna had a narrow open channel, probably a direct result of flows from Indian River which was beginning to breakup. The ice bridges, between Devil Canyon damsite and Devil Creek;' were beginning to show accumulations of ice floes and some jamm~ng activity. No significant water level increases were reported. Above Devil Creek the areas of overflow previously obset~ved, were showing open water. The quantity and extent of open leads 'Nere less upstream of the F,;)g Creek confluence, with no change in river ice above the Watana damsite. May 10-15, 1J82 -Up!;tream of Devil Creek, the river r,howed little change except forr the open leads getting wider and more numerous. The ice in this stretch of lower gradient was formed by border ice that converged but never for·med stable ice bridges or ice barriers, resulting in long, narrow open leads. It seemed that the existing ice cover in this area was melting in place rather than "breaking up". Ice movement began on many reaches of the Susitna River below Devil Creek. All ice bridges had disappeared except for one at river mile 153, where an accumulation of ice floes sl6/a 5 - 8 had jammed and extended several hundred yards upstream. From Portage Creek to Gold Creek, the river was open, with ice jamming at RM 142 and RM 139. The ice cover remained stable about one-half mile below the Gold Creek Bridge. Below Sherrnan, at RM 129 and 130, ice had jammed but appeared unstable and reportedly did not last long. The main channel between RM 118 and RM 120 r·etained its ice cover and appeared stable. Several jams of lesser consequence appeared at RM 115 to 117. At RM 107 (LRX-11), the river remained entirely frozen over. A continuous open lead had formed from Chase upstream to the mouth of Lane Creek. The confluence area was characterized by opening leads on the Susitna, the Chulitna was in final stages of breakup with no ice remaining over the channel. Many ice blocks were stranded on sand bars and bank areas adjacent to the Chulitna. From May 12-15 a jam occurred at RM 107, flooding the railroad tracks and scouring the east bank. Although the jam resp9nsible for the damage has occurr·ed, in generally the same location before, this year's breakup caused unusually severe erosion. The section of railroad track adjacent to the Susitna River at RM 108.5 was undermined when impounded water rose about 15 feet. The ice cover was shorefast, far out into the river channel, con- stricting the flow to a narrow deep channel against the right (west) bank. This cover was very resistent to lifting. Drifting ice blocks were up-ended upon striking this barrier causing water inpoundment and subsequent increases in stage upstream of the jams. Witnesses claim the impounded water rose high enough to erode the railroad grade and wash away several ties (Figure 5.6) and damage the support structure on a bridge (Figure 5. 7) crossing a tributary at RM 110. The jam persisted for three days and backed up ice floes for approximately 1 mile (Figure 5.8) before releasing on May 15. While the jam held, some water flowed over· the ice. An extensive area on the right overbank was also flooded. This was by far the most significant damage in recent years according to railroad personnel. May 27, 1982 -After the final ice drive, a river reconnaissance was made by boat to observe the damage caused during breakup. The river reach just below Talkeetna was characterized by much erosion of river banks on the outside of natural bends. A significant erosion problem exists just downstream of Talkeetna where a cabin, situated on a 10-15 foot bank, is potentially threatened by future breakup scouring of equal severity as this year's. At the confluence, the Susitna left bank at LRX-3 had eroded 3-4 feet, with many mature cottonwood trees now over- hanging the river. At RM 99 and 100, ice blocks measuring 20- 30 feet diameter had been pushed up onto the banks and sand bars. The upstream ends of vegetated islands had been scoured by ice, some being completely denuded of any vegetation for 100 feet or more from the bank. The left river bank had eroded 4-5 feet at RM 102. Areas most notably damaged by ice were characterized by mature ( 15-20 inch) cottonwoods and birch trees s16/a 5 - 9 knocked down and piled up against the upstream ends of islands. The Alaska Railroad had been heavily reinforcing the grade by depositing large rip-rap on the river bank at RM 104 to 105 and 108 to 116. At Slough 9 (RM 129) the effects of breakup were particularly evident. The berm at the head of the slough consisted of unconsolid:;~ted cobbles and sand, suggesting recent deposition. The ground on the islands was covered by 3-4 inches of freshly deposited silt, and ice blocks were observed within the forest, all evidence of a major flooding event. ·The jam which caused this flooding was not observ9d. In addition to the ice jam at Chase, the Alaska Railroad reported damag~:~ to tracks at several locations along the river up to Gold Creek. The most extensively damaged section of railroad track lies between Curry and Chase where recurring ice jams are forfned between LRX-29 and LRX-30. Additional jamming and damage was reported at Railroad Mile 260 (River Mile 132) following an ice jam near LRX-37. Upstream of Gold Greek between RM 141 and 142 is another over- flow channel (Slough 21) which receives flood waters during breakup and high summer flows. Extensive damage to the channel and overbank vegetation was reported after this year's breakup. Scarring of 30 inch cottonwoods to heights of 5 feet above ground level were estimated~ These trees had never seen ice damage before and are situated well above and away from the normal channel. Most of the jams reported in these field observations are reccuring every year and vary only in the degre.e of resultant dsstruction. Since obser·vations were limited during the 1982 breakup, the 1980-81 Ice Observations Report should be consulted for further documentation of additional jam locations. 5. 5 -~ce Thickness ' To further define the 1982 ice regime and to strengthen the data established in 1980 and 1981, ice thicknesses were measured at several of the crest gage sites. These locations were selected since open wa·ter stage-vs. discharge relationships had been established and cross sections had bElen surveyed at all crest gage locations, as well as the fact that these gages were easily located, even in deep snow. Holes were drilled thro\,Jgh the ice cover at .:Avera! representative stations across the channel. With a survey I eve! rod the ice thickness could be measured directly. Table 4.1 lists the average ice thickness as well as the maximum and mm tmum observed. These dat~ can be compared with the 1980-81 Susitna River ice s16/a 5 -10 thicknesses tabulated on Table 3.1 in the 1981 Ice Observations Report (R&M). All available historical data on ice thicknesses have been fully documented in the 198'1 report and will not be presented here. 5. 6 -Devil Canyon Ice Shelves During the winter of 1980-1981, an extensive leveling survey was conducted through Devil Canyon. The formation of broad ice shelves made it possible to obtain a thalweg bottom profile, a water surface profile, and top of ice elevations. For a distance of approximately 1 mile through the canyon, beginning at a temporary bench mark 800 feet downstream of the proposed dam centerline, stations were established at 200-feet intervals and at significant slope breaks. The three required elevations were determined. For a detailed discussion on field procedures and the data acquired refer to Preliminary Channel Geometry, Velocity and Water Level Data for the Susitna River at Devil Canyon, (R&M, April 22, 1981). An abbreviated and lower ordet" survey was conducted in March of 1982 to determine ice thicknesses through the canyon. The data will be useful in defining ice thickness fluctuations from year to year, as well as de·~ermining the effects of ice jamming in the canyon. The data obtained during the 1982 survey are presented in Table 5.2. For illustration purposes, the 1982 stations and corresponding elevations are plotted relative to the 1981 data on the Devil Canyon Map and Profile included in the back envelope. In 1982, the ice shelves measured both narrower (horizontally) and thinner (vertically) than in 1981. The upper section of the canyon at the date of survey showed open w~ter with stable ice shelves forming approximately at the proposed location of the dam centerline. An open water lead continued through the canyon to Station "D" where the ice cover r'esumes. The survey was conducted only on the northern side of the river channel due to access limitations. s16/a 5 -11 ..... TABLE 5.1 SUSITNA RIVER ICE THICKNESS Ice Thickness (ft.)
