The simulations were carried out using the ICECAL model (Harza-Ebasco 1984a) which was submitted to FERC on April 30,1984.Simulations were made for various hydrological and meteorological conditions,for four levels of project energy demands and for two winters of filling of Watana Reservoir. Case C minimum target flows as defined in the License Application were used. Field observations of winter ~ce conditions have been undertaken during the past four years in order to evaluate the possible effects of river ice on the fishery habitat.These observations also provided the data for calibration of the ICECAL model.Thi s chapter summarizes the signi ficant observations of natural conditions and results of the r~ver ~ce simulations. 1.1 NATURAL CONDITIONS Observations of r~ver ~ce (R&M 1981,1982a,1984a,1984b)and slough hydrology (R&M 1982b)made by R&M Consultants,Inc.indicate that: 420673 840802 1 ,... 1.Overtopping of the upstream berm of Slough 8A occurs under natural conditions as observed in the winter of 1982-83.This overtopping allowed slush ice to flow into the slough and form an ice cover.The ice cover eventually deteriorated due to warm upwelling water in the slough,leaving open leads. --I "... 2. 3. Overtopping of the berm at Slough 9 appears to have occurred during the winter of 1982-1983.Maximum water levels attained during the ice- covered period were equivalent to an open water flow of 30,000 to 40,000 cfs in the vicinity of the slough,(R&M 1982b)which would have resulted in overtopping of the berm. Overtopping of the upstream slough berm at Slough 21 was not reported in 1982-1983.However,maximum ice-affected .water surface levels reported for 1982-1983 (R&M 1984a)indicate staging in the vicinity of this slough which caused maximum water levels to be near overtopping of the berm. -- .... - .... The observations of 1982-1983 water levels near Slough 8A and Slough 9 verify the simulation results for natural conditions,which show overtopping of the upstream berms of both sloughs.The simulation of natural conditions was not extended upstream of Gold Creek because of the lack of data on ~ce production,so a comparison of simulated and observed conditions ~s not possible at Slough 21. The mechanism of upstream berm overtopping at Slough 8A ~n the winter ~s described (R&M 1982b).In 1982-1983 the formation of an ~ce cover on the river caused elevated water levels and overtopping of a berm or berms in the vicinity of river mile 127 resulting in flow into the side channel upstream of the northeast berm of Slough 8A.The downstream end of this side channel (also identified as Slough B)was obstructed by ice and thus the flow was shunted over the northeast berm at the upstream end of Slough 8A~near river mile 126.7.Overtopping of the northwest berm at Slough 8A at river mile 126.1 was not reported. 420673 840802 2 - .- ..... ..... ..... Overtopping of the berm at ~he head of the side-channel at river mile 127.1 occurs at a mainstem flow of approximately 17,000 cis (R&M 1982b).This would require a mainstem water level of approximately El.582.5 (Exhibit 4- G,Harza-Ebasco 1984b).The simulation of natural conditions for the winter of 1982-1983 indicates a maximum water level of El.582 at this same location.In order to provide consistency between the natural condition simulations and the observations that the Slough 8A berm was overtopped ~n 1982-1983 it has been assumed that cold mainstem water will enter Slough 8A when the water surface at river mile 127.1 reaches the Threshold El.582. 1.2 SIMULATIONS Instream ice simulations have been made for Watana filling,Watana operating with 1996 and 2001 energy demands and for Watana and Devil Canyon operating with 2002 and 2020 energy demands.A range of winter meteorologic conditions has been simulated to indicate the range of with-project ~ce affected water levels. Meteorology and hydrology for the winters of 1971-1972,1976-1977,1981-1982 and 1982-1983 were used in the simulations.The winter of 1982-1983 generally gave the lowest water levels and shortest ice cover.The 1976- 1977 and 1981-1982 winters both resulted in somewhat more ice and higher water levels than the 1982-83 winter.The winter of 1971-1972 resulted in the greatest ice accumulation and furthest progression of the ice front.In the simulations discussed herein,the winters of 1982-1983 and 1976-1977 represent average winters and 1981-1982 and 1971-1972 represent cold winters.Simulations have also been made for natural conditions for the winters of.1971-1972,1976-1977,1981-1982 and 1982-1983 • 1.1.1 Winter of 1982-1983 -Average Air Temperatures Simulated maximum with-project water levels for Watana only operating are generally three to five feet higher than natural in the reach where an ~ce cover forms;generally downstream of river mile 127.With Watana and Devil 420673 840802 3 ..... ..... - - .... ..... ..... Canyon operating (2002 energy demand),maX1mum water levels would be reduced and would be only one to four feet higher than natural where an ice cover forms j generally downstream of river mile 122.With the 2020 energy demand,the maximum water levels would typically be one to two feet higher than for 2002 and the ice front would advance to river mile 127. For the first year of filling,with discharge through the low level outlet works,the maximum water levels would be one to five feet lower than natural and the ice front would be delayed in reaching Gold Creek until mid February • In general,based on the simulations downstream of river mile 139,maX1mum water levels with-project will be lower than natural upstream of the with- project ice front. 1.2.2 Winter of 1976-1977 -Average Air Temperatures Simulated natural condition water levels would be approximately two feet lower than for 1982-1983 natural conditions and the 1ce front would reach Gold Creek in early Marchj 2-1/2 months later than for 1982-1983 natural conditions.With-project 1ce simulations indicate,with Watana only operating,maximum water levels would be three to eight feet higher than natural downstream of Gold Creek.With Watana and Devil Canyon operating (2002 energy demand)the maximum water levels would be reduced and the ice front would extend to near river mile 127.Maximum water levels would be one to five feet above natural where an ice cover would form.For 2020 energy demands,it is expected that water levels would be one to two feet higher than for 2002 energy demands • For this winter,with-project maximum water levels upstream of the ice cover tend to be equal to or greater than natural conditions due to the small amount of staging under natural conditions. 420673 840802 4 - .... .... .... .... .... 1.2.3 Winter of 1981-1982 -Cold Air Temperatures Maximum water levels for natural conditions would be generally higher than for 1982-1983 conditions by up to four feet.However,in some locations, 1981-1982 natural conditions would result in lower maximum water levels by up to two feet.The ice front would reach Gold Creek in early January, about two weeks later than for 1982-1983.Simulated conditions with Watana operating show the ice front would reach Gold Creek in late January and maximum water levels would be two to eight feet higher than natural.With 'Watana and Devil Canyon operating (2002 energy demand),the ice front may only reach river mile 125.Maximum water levels,where an ice cover forms, would be one to three feet higher than natural.A simulation was not made for 2020 energy demands.However,it is expected that maximum water levels would be one to two feet higher than for the 2002 energy demand. For the second year of filling,maX1mum water levels would be generally less than or equal to natural conditions and the ice front would not reach Gold Creek until mid-February • Maximum with-project water levels upstream of the 1ce cover would generally be less than for natural conditions. 1.2.4 Winter of 1971-1972 -Cold Air Temperature Maximum water levels for natural conditions would generally be equal to or higher than for 1982-1983 natural conditions.The average difference would be approximately two feet.Downstream of river mile 120 the two cases would be very similar.With-project simulations for Watana only operating indicate the ice front would reach Gold Creek three to five weeks later than natural and maximum water levels would be three to six feet higher than natural.With Watana and Devil Canyon operating (2002 energy demand)the ice front would be delayed by three months in reaching Gold Creek and maximum water levels would be one to three feet higher than natural •.For 2020 energy demands the ice front would reach river mile 133 and maximum water levels would be two to six feet higher than natural. -420673 840802 5 .- - .- - - - r In general,it appears that with-project maXlmum water levels upstream of the ice cover would be less than for natural conditions. 1.2.5 Watana Filling The two simulations of Watana filling indicate possible bounds on rlver lce. The first winter of filling,when reservoir releases would be from the low level outlet works and relatively warm,was simulated witq an average winter.The second year of filling,when reservoir releases would be from the surface.and relatively cold,was simulated with a cold winter.The difference between the maximum water levels for the two simulations is on the order of one to two feet.The second year of filling simulation provided higher water levels downstream of river mile 134.Upstream of this point the simulations are similar.The ice front would reach Gold Creek one to two weeks earlier for the second year of filling.For both cases the maximum water levels would be generally less than or equal to natural conditions and the ice front would reach Gold Creek in mid to late February, six to ten weeks later than natural. 1.2.6 Watana Operating In general,with Watana operating,berms at Sloughs 8A and 9 may be overtopped in winters that are colder than 1982-1983.The berm at Slough 21 would only be overtopped in a cold winter such as 1971-1972.Since the berm at Slough 8A is apparently overtopped regularly now and indications are that the berm at Slough 9 may also be overtopped,the frequency of overtopping of these berms with Watana in operation may be·reduced from natural conditions. 1.2.7 Watana and Devil Canyon Operating In general,with Watana and Devil Canyon operating,berms at Sloughs 8A and 9 would be overtopped only 10 cold winters such as 1971-1972.With- project simulations for 1976-1977,1981-1982 and 1982-1983 did not result in overtopping of these berms.Slough 21 would not be overtopped. 420673 840802 6 ..... - - - 2.0 INTRODUCTION This Appendix contains the results of r1ver ice simulations.These simulations were requested by the FERC in April,1983 as part of their Schedule B Request for Supplemental Information.A copy of the comment and the response of the Alaska Power Authority is attached hereto as Exhibit A. Additionally,the simulations 1n this Appendix are cited 1n the Power Authority's comments on the Draft Environmental Impact Statement for the proposed Susitna Hydroelectric Project prepared by the FERC (See comments AQR037 and AQR07l). 420673 840802 7 -3.0 METHODOLOGY The simulations were carried out using the ICECAL model (Harza-Ebasco 1984a,submitted to FERC on April 30,1984).Simulations were made for - various hydrological and meteorological conditions,for four levels of project energy demands and for two winters of filling of Watana Reservoir. Case C m1n1mum target flows as defined in the License Application were used. The r1ver ice simulations have been coordinated with the open water r1ver -temperature simulations.Open water temperature modeling,using SNTEMP, provided the link between the reservoir outlet,which was always above O°C, and the O°C isotherm or the upstream extent of the ice cover,whichever was further upstream. Ice simulations were made for the reach of the Susitna River between Watana Dam site and the confluence of the Susitna and Chulitna Rivers.The ice cover was assumed to progress upstream of the Susitna-Chulitna confluence when the ice capacity of the reach between the Chulitna confluence and the -Yentna confluence was full.Computations were made to determine the ice .... capacity of this reach and the time requlred to fill it based on the computed 1ce production in the Susitna,Chulitna and Talkeetna Rivers.It was assumed the ice cover would reach the Yentna confluence on November 1• Observations indicate that under natural conditions the ice cover begins to progress upstream of river mile 9 near Cook Inlet in October and may reach the Yentna confluence in late October or ear ly November.It is believed that,with project operation,the ice cover will not begin much later than this.Operation of the project will trap considerable frazil ice produced upstream of the dams,thereby reducing 1ce influent to the Lower Reach. However,operation of the project will not affect ice production on the Yentna River,which has been observed to contribute approximately half of the frazil ice in the Susitna River downstream of the Yentna confluence. 420673 840802 8 - Additionally,ice bridge formation at river mile 9 may be dependent on tides and the occurrence of extremely cold weather,factors which are not influenced by the project.Ice front progression past the Yentna River may be delayed somewhat with project,but in order to provide conservatism in the study,November 1 was accepted as the starting date for computations of filling the Lower Reach with ice. Table 1 describes the ~ce simulations provided ~n this Appendix.

Simulations of natural conditions were also made for the winters of 1971- 1972,1976-1977 and 1981-1982.These simulations were made for comparison with project simulations.There are insufficient observations to verify the simulated water levels for any of these years.Natural condition simulations were limited to the reach between river mile 139 and the Susitna-Chulitna con'fluence.This limitation was necessary in order that the frazil ice influent at the upstream boundary under natural conditions could be estimated.It was assumed that the quantity of frazil ice at river mile 139 would be related to air temperature.Observations from 1982-1983 and 1983-1984 at Gold Creek bridge (river mile 136.6)verified this assumption and gave the form of the relationship.It was further assumed that this relationship would hold for cold winters such as 1981-1982 and 1971-1972.No observations are available to confirm or deny this.The quantities of frazil ice influent to the study reach for natural conditions for 1971-1972,1976-1977 and 1981-1982 were computed based on these assumptions and the relationship developed from 1982-1984 data. With-project simulations were not constrained to this study reach downstream of river mile 139.The reservoir temperature and stream temperature simulation models provided the upstream boundary conditions'for with-project simulations.This boundary was always one of the following: 420673 840802 10 - -1.the point ~n the r~ver upstream of the existing ~ce cover where the stream temperature reached DoC,or "'"' - .... 2.the upstream end of the existing ~ce cover if the simulated temperature at the end of the ice cover was aboveO°C. When the O°C isotherm was upstream of the existing ~ce cover,the ice simulation model would compute the amount of frazil l.ce produced in the reach upstream of the ice cover and downstream of the O°C isotherm based on established heat transfer relationships (Harza-Ebasco 1984a).When the temperature at the upstream end of the ice cover was above DoC,the model would compute ice cover melting. In the simulated reach of the river,the entire river width was assumed to be available to pass flow except for overbank areas near certain sloughs which were assumed to be protected by raising of the berms.As indicated ~n the License Application (p.E-3-162),productive sloughs which would be overtopped more frequently than once ~n every ~ive years would be protected. Therefore,overbank areas adjacent to the sloughs shown in Table 2 were considered ineffective for passing ice and water • 420673 840802 11 TABLE 2 SLOUGHS FOR WHICH OVERBANK AREAS WERE CONSIDERED INEFFECTIVE FOR PASSING FLOW - Slough Whiskers II 6A II 8 8C 8B 1:/ Moose A II 8A (west) 8A (east) B 9 9A 2.1 11 17 II 21 (A6)11 21 (Head)11 Location (river mile) 101.5 112~3 114.1 121.8 122.5 123.5 124.5 126.1 127.1 127.1 129.3 133.7 136.5 139.3 141.8 142.2 - ..... II Not listed in License Application (p.E-3-162) Zl Sloughs 8B and 9A were considered protected for all simulations except for the coldest winter of 1971-1972.Protecting these sloughs would result in localized changes (increases)in simulated water levels in the vicinities of the sloughs for 1971-1972 simulations.Simulated water levels at nearby habitat areas,however,would not change significantly,due to the steep gradient of the river.Simulated water levels at all locations for 1976-1977,1981-1982 and 1982-1983 would not change. 420673 840802 12 - The 1ce simulations presented 1n this Appendix should be considered as indicators of general trends rather than precise and exacting simulations. Although the ICECAL model is considered state-of-the-art,modeling of 1ce 1n rivers is a new field and many processes are only beginning to be understood.Field observations of ice affected water levels and ice thicknesses are as difficult to obtain 1n a reliable manner as are observations of 1ce impacts on fish.The calibration report (Harza-Ebasco 1984a),indicates the level of accuracy which can be attained.The model I"'"' has been calibrated to observations for average winters;1982-1983 and 1983- 1984.Insufficient data are available to allow its calibration to a severe winter such as 1971-1972.Additionally,with-project simulations have been made for four winters,1971-1972, 1976-1977,1981-1982 and 1982-1983. During project operation,weather and flow conditions will not necessarily duplicate any of the simulated conditions. Simulations made to date show the model 1S particularly sensitive to the timing of changes in air and water temperature.For example,a comparison of the 1996 and 2001 energy demand simulations for the winter of 1971-1972 shows that the maximum water surface elevations are similar downstream of river mi Ie 137.Upstream of this location,at river mile 141,however, - maximum simulated water levels for the 2001 energy demand are approximately 10 feet higher than for the 1996 demand.A comparison of reservoir outlet temperatures (Appendix IV)for these two energy demands for the winter of 1971-1972 shows a four week period beginning in mid December and lasting until early January when the reservoir out let temperature for the 2001 simulation was approximately 1°C colder than for the 1996 simulation.This resulted in an extra 15 to 30 miles of river at O°C for this period for 2001 as compared to 1996.The frazil ice generated in this reach resulted in greater ice deposition which caused the increased water levels 1n the indicated area.The reservoir temperature profiles for this period,for the 2001 simulation,indicate that water was available in the reservoir which could have been used to raise the outflow temperature to the same level as for 1996 (approximately 2°C)if a lower level outlet had been operated. 420673 840802 13 .... ,.,... - - - - However t the rule for operating the multi-level intake 1S to take the water closest 1n temperature to natural conditions (License Application p.E-2- 119)which,in winter t is O°C. The simulations included in this Appendix present a good picture of the expected winter regime of the study reach under a wide range of hydrological and meteorological condi tions and for various energy demands and project scenarios. -420673 840802 14 - 4.0 RESULTS The following discussion 1S based on an examination of the ice simulation results in this Appendix.The discussion is divided into S1X parts: --1- 2. 3. 4. 5. 6. Natural Conditions Watana Operation -average winter a1r temperatures Watana and Devil Canyon Operation -average winter a1r temperatures Watana Operation -cold winter air temperatures Watana and Devil Canyon Operation -cold winter a1r temperatures Filling of Watana reservoir - ..... ..... - Results of the simulations are summarized 1n Tables 3 through 13 at the end of this section. 4.1 Natural Conditions Simulations of natural conditions were made for the winters of 1971-1972, 1976-1977,1981-1982 and 1982-1983 for comparison with project conditions. The simulation of 1982-1983 provided the bas is for calibrating the lCECAL model to field observations.An additional calibration simulation was made fo.r the 1983-1984 winter (see Doc.1122).This simulation is not shown here and with-project simulations were not made for this year because of its similarity to 1982-1983 conditions.There are no observations of maX1mum water levels,1ce thicknesses and ice front progression which can be compared to the simulated conditions for 1971-1972,1976-1977 or 1981-1982 to verify these simulations. For the winter of 1982-1983,the ice front advanced to Gold Creek by mid- January,after stalling for some time downstream of the Gold Creek bridge. The simulation of the 1982-1983 winter followed the progression of the ice front well until this point.The simulation showed an advance past Gold Creek approximately three weeks earlier than observed.Simulated ice thicknesses and water levels were within acceptable limi ts.The ice cover 420673 840802 15 "'"'" - - """' ..... ..... - - .- - - resulted in staging of between two and S1.X .feet relative to open water levels. The simulation of natural conditions for 1971-1972 indicated the ice front would progress past the Susitna-Chulitna confluence (river mile 103)1.n early November and reach Gold Creek by mid-December,similar to 1982-1983 conditions.Maximum water levels would be similar to 1982-1983 conditions downstream of river mile 120 and slightly higher upstream of that.The ice cover resulted in staging between three and ten feet relative to open water levels. The simulation of natural conditions for 1976-1977 indicated the ice front would progress past the Chulitna-Susitna confluence in early December and reach Gold Creek in early March.Maximum water levels would be up to four feet lower than for 1982-1983.The ice cover resulted in staging of between two and five feet relative to open water levels. The simulation of natural conditions for 1981-1982 indicated the 1.ce front would advance to the Chulitna-Susitna confluence by mid-November and would reach Gold Creek by early January.Maximum water levels would generally be higher than 1982-1983 conditions.The ice cover resulted in staging of three to eight feet relative to open water levels. 4.2 Watana Operation -Average Winter Air Temperatures For Watana only operating for the winter of 1982-1983,the maX1.mum upstream extent of the ice cover for 1982-83 would be near river mile 127 for 1996 energy demands and river mile 124 for 2001 energy demands.A comparison of the simulated natural and with-project (Watana only)conditions for this year indicates that water levels attained near the berms of Slough 8A (RM's 126.1,127.1)and Slough 9 (RM 129.3)with-project for both 1996 and 2001 energy demands are generally less than or equal to those attained under natural conditions.At Slough 8A,for a period of approximately three days in late December,the simulated water level for 1996 energy demand exceeds the natural conditions. 420673 840802 16 .... .... .... - - For the winter of 1976-1977,with Watana only operation,the max~mum upstream extent of the ice cover reached river mile 137,upstream of the Gold Creek Bridge,for 1996 energy demands.Maximum water surface levels attained at the berms of Slough 8A were 4 to 6 feet higher than under simulated natural conditions.The max~mum water level attained at the upstream berm at Slough 9 would be approximately 4 feet higher than simulated for 1982-1983 natural conditions. For average winter conditions for Watana only operation,for the two simulations carried out,the maximum upstream extent of the leading edge varied betwen r~ver miles 124 and 137.With-project,the ~ce front leading edge tends to respond to changes in air temperatures which induce changes in the water temperatures released from the reservoir or which induce changes in the rate of cooling of open water between the dam and the leading edge location. It appears that where an ice cover exists with-project,the ~ce related water level will be higher than under natural conditions.However,this may not resul t in an increased frequency of slough berm overtopping since the leading edge of the ice may not progress upstream past Sloughs 8A,9 and 21 as frequently as during natural conditions. 4.3 Watana and Devil Canyon Operating -Average Winter Air Temperatures During average winters (as illustrated by 1982-83)with Watana and Devil Canyon in operation with energy demands as for 2002,the maximum upstream extent of the leading edge of the ice cover will reach river mile 122, approximately two to five miles downstream of the leading edge attained under similar conditions with Watana only operating,based on our simulations.Maximum ice thicknesses attained are somewhat similar to Watana only conditions downstream of river mile 117,and much thinner upstream of this.Maximum water levels attained are approximately 1 to 3 feet lower than with Watana only downstream of river mile 117 and 4 to 5 feet lower upstream.Downstream of river mile 117 the primary reason for the reduction in water surface level from Watana only operation is the 420673 840802 17 winter discharge which 1S less than the discharge with Watana only operation.For 2020 energy demands,the leading edge would progress to near river mile 126,similar to Watana only operation 1n the same winter. Maximum water levels would be lower than for Watana only operation downstream of river mile 115 and similar to those for Watana only operating upstream of river mile 115.- A comparison of the results with simulated natural conditions shows that in the reach where an ice cover forms,downstream of Slough 8A,maximum water levels will be 1 to 5 feet higher than for natural conditions. - - - - Based on a simulation of 1976-1977 winter conditions,the ice cover would reach approximately river mile 127.Maximum water levels attained would be 1 to 4 feet lower than with Watana only operation.Maximum water levels would be higher than simulated natural conditions by 2 feet at the Slough 8A northwest berm,by 1 foot at the berm at river mile 127.1 and 1 foot lower than natural conditions at the Slough 9 berm.The northeast berm of Slough 8A might not be overtopped and the Slough 9 berm would probably not be overtopped. 4.4 Watana Operation -Cold Winter Air Temperatures The simulation of Watana operation for the 1981-1982 winter for 1996 energy demands shows a maximum upstream progression of the ice leading edge to near river mile 137,upstream of Gold Creek Bridge.The maximum water levels attained are zero to one foot higher than the maximum water levels for the winter of 1982-1983 (Watana operation)in the reach downstream of river mile 116.In the reach upstream of river mile 116,maximum water levels are 2 to 5 feet higher with an average of 3 feet higher.The maX1mum attained water levels are between 2 and 8 feet higher than simulated natural conditions. The simulation of the winter of 1971-1972 provided the highest water levels and furthest upstream progression of the ice front.Simulations were made for 1996 and 2001 energy demands.The results for 1996 and 2001 are -420673 840802 18 ----------------------------------------------_. .- - - ,~ - - similar,although further upstream progression of the ~ce front occurs ~n the 2001 energy demand simulations.Between river miles 132 and 142 the 2001 energy demand simulation gives stages 3 to 10 feet higher than the 1996 demand simulation.For the 2001 simulation,the leading edge reached river mile 142 and maximum water levels were on the average 2 feet higher than for the winter of 1981-1982 for Watana only operating,2 to 7 feet higher than the winter of 1982-1983 with Watana operating and 2 to 3 feet higher than the winter of 1976-1977 with Watana operating. For the two cold winters simulated,the leading edge of the ice progressed to river miles 137 and 142.Water levels at Slough 8A berms were 2 to 3 feet above simulated natural conditions for the 1981-1982 simulation and 2 to 4 fee t above simulated natural conditions for 1971-1972 condi tions. Water levels at Slough 9 were 2 to 5 feet higher than simulated natural conditions for 1981-1982 and 1971-1972 simulations,respectively.This indicates that these sloughs would be overtopped. 4.5 Watana and Devil Canyon Operating -Cold Winter Air Temperatures The winters of 1981-1982 and 1971-1972 were used for simulating cold winter conditions for Watana and Devil Canyon operating.The 1981-1982 simulation was made for 2002 energy demands and indicates fhat,with Devil Canyon operating,the maximum water levels attained in a cold winter are similar to those attained with Devil Canyon operating ~n an average winter (1982-83). Maximum water levels are generally within a foot of those attained in the average winter.In some places the max~mum water levels in the cold winter are less than those in the average winter.In the 1981-1982 simulation the leading edge of the ice cover reached r~ver mile 126,approximately 4 miles upstream of the average winter. A comparison can also be made with the cold winter conditions for Watana only operating.This shows that with Devil Canyon the maximum water levels are 2 to 4 feet lower downstream of r~ver mile 115 and 5 to 9 feet lower upstream of river mile 115.Additionally,the ~ce cover during the cold winter with Devil Canyon would only reach a point approximately 10 miles -420673 840802 19 - - "... downstream of the maximum extent with Watana only operating.Wi th Devil Canyon operating,maximum water levels in a cold winter such as 1981-1982 would be only 1 to 2 feet higher than under natural conditions for an average winter.For the cold winter of 1981-1982,with Devil Canyon operating,the maximum upstream extent of the ice cover did not reach the berms at Slough 8A. Simulations of ice processes were also carried out for the winter of 1971- 1972 for Watana and Devil Canyon operating for 2002 and 2020 energy demands. The 2020 demands required greater discharge from the reservoirs resulting in maximum water levels approximately 2 feet higher than for 2002 energy demands.However,for 2020 demands,the leading edge of the ice front would reach river mile 133 approximately 4 miles downstream of its maximum extent for 2002 energy demands.The maximum water levels attained for 2020 energy- demands would be approximately the same as for similar winter weather with Watana only operating with 2001 energy demands,although the maximum extent of the leading edge would be approximately 9 miles downstream of its extent for Watana operating.For 2020 energy demands the maximum water levels would be 2 to 6 feet higher than for simulated natural conditions.A comparison of maX1mum water levels for Watana and Devil Canyon operating in a cold winter with an average winter indicates that for the cold winter the water levels are generally the same or slightly higher (by 1-2 feet) downstream of r:iver mile 117.Upstream of river mile 117 the water levels are generally 5 feet higher during the cold winter. For Watana and Devil Canyon operating for a cold winter such as 1971-1972, the upstream berms of both Slough 8A and Slough 9 would be overtopped. 4.6 Watana Filling River ice conditions have been simulated for the first and second winters of Watana filling for average and cold winter air temperatures,respectively. During the first winter of Watana filling the reservoir outflow would be similar to natural conditions in quantity but the temperature at the reservoir outlet would be near 4°C as the water would be drawn from the 420673 840802 20 - bottom of the reservoir.During the second winter of filling the reservoir water level would exceed the elevation of the mid-level outle t works and relatively cold reservoir surface water would be discharged through the mid- level outlet works.The quantity of flow during the second winter woul.d again be similar to natural conditions as indicated in the License Application (p.E.2.78).River ice conditions during the third winter of filling would be similar to those during normal Watana operation since the powerhouse would be operational. In order to find the maximum upstream and downstream bounds of the ~ce cover during filling,the following simulations were made: 1.The first winter of filling when reservoir discharges would be near 4°C was simulated with the 1982-1983 average winter,and 2.The second winter of filling when reservoir discharges would be relatively cold was simulated with the 1981-1982 cold winter. The simulations for both the first and second winters of filling indicate that the maximum water levels attained would be generally equal to or lower than those obtained for natural conditions for the average winter of 1982- 1983.The ice front would reach the vicinity of Gold Creek,near river mile' 135 in mid-February and early February for the first and second winters of filling,respectively.This would be much later than natural conditions. The simulations indicate that the ~ce front would reach river mile 162. However,field observations indicate that the continuous ice cover may only reach Gold Creek.Between Gold Creek and Devil Canyon the ~ce cover will form in a manner similar to natural conditions with border ice growth being the predominant mechanism.Insufficient data are available to allow accurate estimation of ice cover progression upstream of Gold Creek for filling simulations.There is inadequate channel geometry information available for Devil Canyon (upstream of river mile 152).However,it is believed the ice cover will form in this reach much the same way as under natural conditions. 420673 840802 21 ..... ....

Table 14 lists the locations for which berm overtopping flows are available and for which threshold elevations were computed.Overtopping discharges were obtained from observations by R&M Consultants,Inc.(R&M 1982b)and the Alaska Department of Fish and Game (ADF&G 1983 and 1984).Overtopping discharges for Sloughs 8A,9 and 21 are as indicated in the License Application (Appendix E.2.A). -420673 840802 45 TABLE 14 THRESHOLD ELEVATIONS AT SIGNIFICANT LOCATIONS Mainstem Threshold River Overtopping Water Location Mi 1el./Dischargel./Leve1]./Source -(cfs)(ft.ms1) Whiskers Slough head 101.5 18,000 367 ADF&G 1983-Slough 8 head 114.1 25,000 476 ADF&G 1983 Side channel Mainstem """II -NW head 115.5 12,000 482 ADF&G 1984 Side channel Mainstem II -NE head 115.9 23,000 487 ADF&G 1984 Slough 8A head (NW)126.1 26,000 573 License ~Application Slough 8A head (NE)127.1 -!i/582 R&M 1982b .-Slough 9 head 129.3 20,500 604 License Application Slough 9A head 133.7 19,600 (est.)651 ADF&G 1984 ~ Side channel upstream of Slough 10 134.3 <19,000 657 ADF&G 1984 Slough 11 head 136.5 42,0002/687 ADF&G 1983 Slough 20 head 140.5 20,000 730 ADF&G 1983 .-Slough 21 (A6)141.8 18,000 747 ADF&G 1984 Slough 21 head 142.2 24,000 -755 License 26,000&./Applicat ion Slough 22 head 144.8 21,000 788 ADF&G 1983 420673 840802 46 ...... Footnotes for Table 14 II River mile indicated is within 0.2 mile of slough berm. 11 Mainstem discharge at which indicated berm would be overtopped. 1.1 Water surface elevation in mainstem at given river mile corresponding to overtopping flow,rounded to nearest foot. !:il In the winter of 1982-1983,the ice affected water level in the vicinity of river mile 127 exceeded the elevation of the berm at the head of the side channel upstream of Slough 8A.At the same time l.ce was obstructing the downstream end of the side channel at river mile 126.5. This caused flow to be shunted into Slough 8A.The berm at river mile 127.1 would be overtopped at a flow of approximately i7,000 cfs (R&M 1982b). Therefore,it appears that the ice affected water level would need to exceed Elev.582 at river mile 127.1 in order for Slough 8A to be overtopped,in the winter. 2.1 The berm at the head of Slough 11 is in a side channel.The downstream end of this side channel is near river mile 136.2 It appears that when the water surface at river mile 136.2 reaches El.684 (the level of the slough berm),backwater in the side channel will overtop the slough berm. Q/Overtopping discharges for berms at northwest channel and northeast channel are 24,000 cfs and 26,000 cfs,respectively. 420673 840802 47 For the period November to April,the SNTEMP open-water temperature simulations provided in Appendix V should always be used in conjunction with the ice simulations in this Appendix for the same period.The SNTEMP model does not give accurate temperature simulations under an ice cover. Therefore,in areas where an ice cover is simulated to occur,the temperatures shown in this Appendix should be used.The temperatures in ..... Appendix V are valid upstream of the ice cover.Under the ice cover,the temperatures would be as simulated by ICECAL and as shown on the plots in this Appendix.The approximate location of the ice front has been plotted on the exhibits in Appendix V to aid in the use of those plots. The locations of the O°C isotherm shown on the exhibits in Appendix V and Appendix VI were not plotted in the same manner.In Appendix V,locations of O°C were plotted at mid-week of the week they were simulated for and the points were connected.For the ice simulation studies "the locations of O°C were used to represent conditions for the entire week and were plotted as weekly values.River ~ce simulations were made on a daily basis us~ng -weekly average flows and temperatures.This computation interval was necessary to provide accurate simulation of the mechanical processes involved in ice cover formation. r- ! ..... ..... .... .... 420673 840802 48 TABLE 15 RIVER ICE SIMULATIONS INCLUDED IN EXHIBITS Energy Meteorologic Description Demand Hydrologic Winter Summer Exhibit Project Status Year Data Year Temps Flows B Natural Conditions 1971-1972 Cold Wet C Natural Conditions 1976-1977 Average Dry D Natural Conditions 1981-1982 Cold Wet E Natural Conditions 1982-1983 Average Average F Watana filling first winter 1982-1983 Average Average G Watana filling second winter 1981-1982 Cold Wet H Watana operating 1996 1971-1972 Cold Wet ~I Watana operatirtg 1996 1976-1977 Average Dry J Watana operating 1996 1981-1982 Cold Wet K Watana operating 1996 1982-1983 Average Average L Watana operating 2001 1971-1972 Cold Wet ~M Watana operating 2001 1982-1983 Average Average N Watana &Devil Canyon operating 2002 1971-1972 Cold Wet 0 Watana &Devil Canyon operating 2002 1976-1977 Average Dry J-DevilPWatana& Canyon operating 2002 1981-1982 Cold Wet ~Q Watana &Devil Canyon operating 2002 1982-1983 Average Average r-R Watana &Devil Canyon operating 2020 1971-1972 Cold Wet S Watana &Devil~ Canyon operating 2020 1982-1983 Average Average - ..... 420673 840802 49 - EXHIBIT A ....

(~ .- .- Response Documentation for ICESIM is not avai lable because the model·is proprietary. However,as part of the on-going environmental studies,a comprehensive ice simulation model will be employed to verify results given in the application.This model will be fully available for documentation and will be verified for pre-project winter flow regimes on the Susitna,and,if sufficient information can be obtained,for other rivers with winter flow regimes similar to the post-project conditions. The proposed work plan for the ice simulation modeling is given below: Work Plan The proposed work plan will be accomplished in three steps:model vertifi- cation,preliminary studies,and final studies. Model Verification:A state-of-the-art mathematical model wi 11 be used to estimate ice production and ice cover progression and thickening.The mathematical model wi 11 first be calibrated with ice observation data on the Susitna River.In previous studies using ICESIM,it became apparent that the model could not simulate the ice regime at numerous cross sections where critical or near critical velocities occur in the river during low flow 2-41-1 ----------_._------------_._------------------ conditions.However,since the post-project winter discharge will be sig- nificantly higher than pre-project winter flows~this verification to the available ice observation data would be useful only to demonstrate the accuracy of the model for extreme low winter releases.Therefore~other rivers.with higher winter flow rates and stages wi 11 be considered if sufficient data can be obtained. Preliminary Studies: of necessary changes follows: Previ ous studi es wi 11 be revi ewed with an assessment to the scope of work.These studi eswi 11 proceed as - .F'" -~ a.Revi ew reservoi r di scharge quantity and temperature presented in the License Application for comparison with results from the most recent studies.Also compare open-river water profi 1es presented in the License Application with the latest available results. b.Use available open-water surface and temperature profi les to pro- ceed with preliminary ice-model runs.Compare results to runs common to both License Application level studies and current studies.The ice model wi 11 i ncl ude an open -water temperature algorithm which wi 11 be used to determine both the temporal and spatial distribution of ice production.When the river tempera- ture profi les from the instream temperature modeling using the SNTEMP model are available (see response to Comment 40),the starting location and timing of ice production may be adjusted. c.Review the adequacy of License Application ice simulation runs especially in view of the difficulty in calibrating the model. d.Review the adequacy of limiting hydraulic and ice studies to the reach upstream of Talkeetna. 2-41-2 .... ..... .... e.Review the adequacy of assumptions made with regard to tributaries of the Susitna River between Watana dam site and Talkeetna. Final Studies:Following verification of the model and preliminary runs, final runs will commence.Final runs will require temperature output data at Watana and Devil Canyon from the reservoir operation and reservoir temp- erature models and water profi le data from the river.hydraulic model. Results of instream temperature modeling using SNTEMP model will be consid- ered and adjustment of the location of ice production may be r~quired• Typical production runs would include the following: a.Open-water surface and temperature profi les downstream from the dame s),for various power di scharge hydrographs and for average and extreme wi nter weather conditions.These runs wi 11 esti mate the initial location and timing of ice production in the river for the study conditions described. b.Ice development runs for the time and location of ice production downstream from the dames)during the winter,including ice thick- ening,areal extent,"staging,"and ice-cover break-up.
