HYDKllELECTRIC PROJECT RESPONSE OF JUVENILE CHINOOK HABITAT TO MAINSTEM DI~CHARGE IN THE TALKEETNA-TO-DEVIL CANYON SEGMENT OF THE SUSITNA RIVER, ALASKA PREPARED BY: CLEVELAND R. STEWARD, III R. CURT WILKINSON ALEXANDER MILNER TRIHEY AND ASSOCIATES Under Contract To Harza-Ebasco Susitna Joint Venture Prepared for Alaska Power Authority Draft Report September 1985 PREFACE The goal of the Alaska Power Authority in identifying environmentally acceptable flow regimes for the proposed Susitna Hydroelectric Project is the maintenance of existing fish resources and levels of production. This goal is consistent with mitigation goals of the U.S. Fish and Wildlife Service and the Alaska Department of Fish and Game. Maintenance of naturally occurring fish populations and habitats is the preferred goal in agency mitigation policies. In 1982, following two years of baseline studies, a multi-disciplinary approach to quantify effects of the proposed Susitna Hydroelectric Project on existing fish habitats and to identify mitigation opportunities was initiated. The Insteam Flow Relationships Studies focus on the response of fish habitats in the middle Susitna River to incremental changes in main- stem discharge, temperature and water quality. As part of this multi- disciplinary effort, a technical report series was planned that would (1) describe the existing fish resources of the Susitna River and identify the seasonal habitat requirements of selected species, and (2) evaluate the effects of alternative project designs and operating scenarios on physical processes which most influence the seasonal availability of fish habitat. The summary report for the IFRS, the I nstream Flow Rel ati onshi ps Report (IFRR), (1) identifies the biologic significance of the physical processes evaluated in tt;ie technical report series, (2) integrates the findings of the technical report series, and (3) provides quantitative relationships and discussions regarding the influences of incrementa 1 changes in stream- i i flow, stream temperature, and water quality on fish hab i tats i n the midd l e Susitna River on a seasonal basis. The IFRR consists of two volumes. Volume I uses project reports, data ana professional judgment available before March 1985 to identify evaluation species, important life stages, and habitats. The report ranks a variety of physical habitat components with regard to their degree of influence on fish habitat at different times of the year. This ranking cons i ders t he biologic requirements of the evaluation species and life stage, as well as the physical characteristics of different habitat types, under both natura l and anticipated with-project conditions. Volume II of the IFRR will address the third objective of the IFRR and provide quantitative relation- ships regarding the influences of incremental changes in streamflow, stream temperature, and water qual i ty on fish habitats i n the middle Susitna River on a seasona 1 basis. The influence of incremental changes in streamflow on the availability and quality of fish hab i tat is the central theme of the IFRR Volume II analysis. Project-induced changes in stream temperature and water quality are used to condition or qua 1 i fy the forecasted responses of fish hab i tat to instream hydraulics. The influence of streamflow on fish habitat wi ll be evaluated at the microhab i tat level and presented at the macroh abi tat level in terms of a composite weighted usable area curve. This composite curve will describe the combined response of fish habitat at all sites within the same representative group to incremental changes in mainstem discharge. iii Four technical reports are being prepared by E. Woody Trihey and Associates in support of the IFRR Volume II analysis. The function of each report is depicted in a flow diagram and described below. Quantify Wetted Surface Area Response Assess the Representa- tiveness of Modeled and Non-modeled Sites Determine Site- Specific Hydraulic Conditions Quantify Streamflow-Dependent Habitat Response Functions for Juvenile Chinook and Spawning Ch~ Salmon RESPONSE OF AQUATIC HABITAT SURFACE AREAS TO MAINSTEM DISCHARGE IN THE TALKEETNA-TO-DEVIL CANYON SEGMENT OF THE SUSITNA RIVER, ALASKA This report identifies five aquatic habitat types within the middle Susitna River directly influenced by changes in mainstem discharge and presents the necessary photography and surface area measurements to guantif~ the change in wetted surface area associated with incrementa decreases in mainstem discharge be- tween 23,000 and 5,100 cfs. The report also describes the in- fluence of mainstem discharge on habitat transformations and tabulates the wetted surface area responses for 172 specific areas using the ten representative groups presented in the Habitat Characterization Report. Surface area measurements presented in this report provide a basis for extrapolating results from intensively studied modeling sites to the remainder of the middle Susitna River. CHARACTERIZATION OF AQUATIC HABITATS IN THE TALKEETNA-TO-DEVIL CANYON SEGMENT OF THE SUSITNA RIVER, ALASKA This report describes the characterization and classification of 172 specific areas into ten representative fro~ps that are hydro- lo icall h draulicall and mor holo ica 1 similar. Emphasis is p aced on the trans ormat on o speci ic areas from one habitat type to another in response to incrementa 1 decreases in mainstem discharge from 23,000 cfs to 5,100 cfs. Both modeled and non-modeled sites are classified and a structural habitat index is presented for each specific area based upon subjective iv evaluation of data ootainea through field reconnaissance surveys. Representative groups and structural habitat indices presented in this report provide a basis for extrapolating habitat response functions developed at modeled sites to non-modeled areas within the remai naer of the river. HYDRAULIC RELATIONSHIPS AND MODEL CALIBRATION PROCEDURES AT 1984 STUDY SITES IN THE TALKEETNA-TO-DEVIL CANYON SEGMENT OF THE SUSITNA RIVER, ALASKA This report describes the influence of site-specific hydraulic conditions on the availability of habitat for Juvenile chinook and spawning chum salmon. Two aquatic habitat models are applied to quantify site-specific habitat responses to incremental changes in depth and velocity for both :iteaay and spatia 11 y varied streamflow conditions. Summaries of site-specific stage- discharge and flow-discharge relationships are presented as well as a description of data reduction methods and model calibration procedures. Weighted usable area forecasts are provided for juvenile chinook at 8 side channel sites ana for spawning chum salmon at 14 side channel ana mainstem sites. These habitat response functions provide the basis for the instream flow assessment of the miaale Susitna River. RESPONSE OF JUVENILE CHINOOK AND SPAWNING CHUM SALMON HABITAT TO MAINSTEM DISCHARGE IN THE TALKEETNA-TO-DEVIL CANYON SEGMENT OF THE SUSITNA RIVER, ALASKA This report integrates results from the surface area mapping, habitat characterization, and hydraul 1c modeling reports to rovide streamflow de endent habitat res onse functions for j uveni e chi nook and spawning chum sa man. Wetted surface area and weighted usable area are the principal determinants of habi- tat indices provided fn Part A of the report for juvenile chinook at each specific area and the ten representathe groups i aenti- fied in the habitat characterization report. Part B of this report provides habitat response functions for existing chum sa 1 mon spawning sites. The habitat response functions conta i nea in this report will De used for an incremental assessment of the rearing and spawning potential of the e~tire middle Susitna River under a wide range of natural and with-project streamflows. v TABLE OF CONTENTS Page No. PREFACE............................................................... ii LIST OF FIGURES •....••.•••...••...........•••...•.................... viii LIST OF TABLES...................................................... x.iv LIST OF PLATES.......................................................

The response of juvenile chinook habi- tat to changes in streamflow within this middle reach of the Susitna River has been the subject of several years of data collection ana modeling stuaies conaucted by the Alaska Department of Fish and Game (ADF&G) and E. Woody Trihey and Associates (EWT&A). These investigations are part of an extensive environmental assessment program conducted to ful fi 11 licensing requirements for the proposed Susitna Hydroelectric Project. The Alaska Power Authority (APA), the state agency responsible for developing the hydropower potential of the Susitna Ri'ler, has indicated a desire to maintain or enhance existing fish resources ana levels of produc- tion within affected reaches of the ri'ler (APA 1983). This goal may be attainable through a 'lariety of mitigative options (Moulton et al. 1984). However, to protect existing fisheries resources ana to ensure the success of selected mitigation ana enhancement efforts, it is necessary to i dentify ana adopt instream flows ana reservoir operation sche a ules wh i ch will provide for the needs of the fish species inhabiting the middle Sus itna Ri'ler. The storage ana release of water to meet the instream flow needs of fishes aowns tream is not necessarily ae 1 eteri ous to hyaropower interests. The recharge ana storage capabilities of the proposed De'lil Canyon ana Watana reservoirs Lrefer to APA (1983) for a aescription of the aesign criteria ana c onstruction schedule for these facil i ties] will perm i t water to be 1 stored during periods when natural runoff exceeds Doth the water demand for power generation and the instream flow needs of resident ana ana<lromous fishes. This will allow for the controllea release of water <luring periods of greatest need. Peak aemand for electricity typically occurs <luring the working <lay on a 24 hour cycle and <luring the winter on a seasonal Dasis. The frequency and rate of change of daily flow fluctuations in th~ middle reach may De of significant concern if the Watana <lam alone is constructed ana subsequently operatea as a peak loaa following facility. However, if Doth aams are Duilt, aaily flow fluctuations are expected to De minimal, <lue to the anticipated regulating capability of the proposed Devil Canyon <lam. Over the long term, however, use of the ccmDinea storage volume of the two reservoirs to satisfy peak seasonal power aemana will result in lower summer ana higher winter flows than presently occur. Figure 1 compares natural with simulated with-project mean weekly discharges for the middle Susitna River. Projected with-project flows are for 1) Watana reservoir operating alone assuming energy <lemana forecasts for 1996; ana 2) oath Watana ana Devil Canyon reservoirs in operation, Dasea on projected aemana for 2020. These with-project flow scenarios correspona to Case E-VI, aemana levels Band D, respectively (Harza-Ebasco Susitna Joint Venture 1985). As the <lemana for electricity varies over time, so ao the instream flow neeas of a fish species vary according to their life history stage.

Simulated with-project flows are based on Case E-VI, demand levels Band D (data from Harza-Ebasco Susitna Joint Venture 1985) . the reproauctive and early post-emergent fry life stages of chinook (unlike those of chum, pink ana sockeye salmon which spawn in both tributary and non-tributary habitats of the middle Susitna River) are not likely to be affectea by project operation. The later freshwater life stages of chinook salmon, incluaing juvenile and migratory phases, will be suojectea to alterea streamflow regimes since they utilize mainstem ana mainstem- i nfl uenced habitats . The summer growth season is a cri ti ca 1 period for 3 chinook juveniles since it is at this time that aensity-aependent factors typically have their greatest effect on the population. Due to the economic importance of the species, the ecological sensitivity of the life stage, ana their extensive use of mainstem-associatea hal>itats, chinook juveniles have Deen designated as a primary evaluation species to De used in analyses of existing ana with-project conditions. Chum salmon spawning ana incul>ation life stages comprise the other two primary species /life stages selected for evaluation (EWT&A and Woodward-Clyde Consultants [WCC] 1985).

During the remainder of their freshwater residency, which usually lasts until the spring of the following year, juvenile chinook occupy a wiae range of hal>itats. Densities are highest in tril>utaries, siae channels ana siae sloughs, respectively, <luring the open water season (Figure 2). Chinook aistril>ution during the winter months is not well aocumentea other than a noted tendency for individuals in mainstem ana siae channel areas to seek relatively warmer upwelling areas found in siae sloughs. A significant numDer of young-of- the-year chinook apparently migrate downstream late in the summer, although it is uncertain whether they overwinter in fresh or saltwater (Dugan et al. 1984). 4 chinook Juveniles since it is at this time that aensity-aependent factors typically have their greatest effect on the population. Due to the economic importance of the species, the ecological sensitivity of the life stage, and their extensive use of mainstem-associated habitats, chinook juveniles have been designated as a primary evaluation species to be used in analyses of existing ana with-project conditions. Chum salmon spawning and incubation life stages comprise the other two primary species/life stages selected for evaluation (EWT&A and Woodward-Clyde Consultants [WCC] 1985). Following emergence in March and April juvenile chinook typically spend several months rearing in their natal streams. However, the numbers and biomass of juvenile fish usually exceeds the carrying capacity of the tributaries by miasummer and a large fraction of the chinook population responds by emigrating to the Susitna River. During the remainder of their freshwater residency, which usually lasts until the spring of the following year, juvenile chinook occupy a wide range of habitats. Densities are highest in tributaries, side channels and side sloughs, respectively, auring the open water season (Figure 2). Chinook distribution during the winter months is not well aocumentea other than a notea tenaency for individuals in mainstem ana side channel areas to seek relatively warmer upwelling areas found in side sloughs. A significant number of young-of- the-year chinook apparently migrate aownstream late in the summer, although it is uncertain whether they overwinter in fresh or saltwater (Dugan et al. 1984). 4 U1 .... z w 0 £t w 0. .... z w 0 £t w 0. 60 50 40 30 20 10 60 50 4D- 30- 2Q- 10 0 60 40 ~ ~ 30 ffi ~··1 a.. 20 10 e.e 0~------+-------+-~~--+-------i TRIBUTARIES UPLAND SIDE SIDE TRIBUTARIES UPLAND SIDE SIDE SLOUGHS CHANNELS SLOUGHS CHUM 11.0 ~' R9 J .

SOCKEYE Percentage aistrioution of juvenile chinook s ~lmon within d1fferent haoi tat types of the middle Sus 1tna River auri ng the open water period (from E. Woody Trihey an<l Associates and Woodward-Clvde Consultants 1985). The biological ana physical factors affecting juvenile chinooK salmon in their rearing environment are complex. Milner (1985) critically reviewed these environmental factors and their effects. Fooa availability, preda- tion, competition, ana the incidence of disease and parasitism are among the more important biological factors. All are mediatea to some degree oy the quantity ana quality of physical habitat which constitute the fish's living space. Physical habitat includes the combination of hydraulic, structural and chemical variables to which juvenile chinook respona either behaviorally or physiologically. Stream temperature, turbidity, suspended sediment level, water depth and velocity, cover, and substrate texture are important physical habitat variables which are either airectly or indirectly influenced by the volume and pattern of streamflow. The goal of minimizing potentially adverse effects of flow alterations associated with hydropower generation is possible only if the magnitude of the impacts is known, thereoy presenting two major proD 1 ems. The first relates to the quantification of existing resources an<1 the relationships which sustain them. The second problem is methodological: how can predic- tions of with-project conditions be superimposed on natural conditions to enable accurate forecasts? Existing ana with-project conditions have not been sufficiently aefined to offer straightforward solutions to these problems. For one, our knowleage of the population dynamics of chinooK salmon s-c.ocks of the middle Susitna River yields little insight into their likely long-term response to with- project flow regimes. Population adjustments are frequently determinea by combinations of environmental properties occuring far in advance of the 6 Dialogical response. Thus, although fish production and its component parameters (i.e., density, mortality, growth, etc.) may eventually reflect the influence of causative environmental factors, the complexity of these relationships is too great and there is too much variability in our esti- mates to Dase our forecasts entirely on population stuaies. We are not limited as much by our ab;lity to conceptualize the relationships linking juvenile chinook to their environment as we are Dy our ability to measure and test these relationships. This problem is not a new one. Fisher1es Dialogists faced with the task of identifying acceptable instream flows often make their selection because it appears to make biological sense, and not on the basis of mathematically defined relationships between streamflow and biological response. In the past decade, however, an instream flow assessment methodology has been developed which partially bridges this gap. The Instream Flow Incremental Methodology (IFIM) described by Bovee (1982) provides a computer assisted capabi 1 i ty of simulating important components of fish habitat based on site-specific field measurements. The suitability of fish habitat at a given flow is evaluated by reference to preference criteria. There are frequency distributions which describe the probability that a fish will be found in association with a particular level or interval of the habitat component in question. Once the spatial distribution and levels of habitat components are known or are reliably simulated for a range of flows, ana the relationships between these components ana behavioral preferences have been quantified, then a habitat response index may be calculated for each flow of interes •• Following standard IFIM terminology, this habitat response index is termea Weighted Usable Area (WUA). From an assumption 7 that the carrying capacity of a stream varies with the amount of usable physical habitat, the direction ana magnitude of WUA may be consiaered reliable indicators of the probable population response to discharge alterations. This assumption has been verified for some salmonid streams but not for others (Nelson 1980, Loar 1985). Factors other than the amount of usable habitat, such as inadequate fooa supplies ana catastrophic events (e.g., flooas), may have been responsible for the conflicting results. For purposes of this report, the concept of habitat preference appears valia and the linkage between biological response and flow-relatea habitat changes, as indexed by WUA, 1s considered strong enough to make inferences concerning the present status ana likely trends in juvenile chinook populations. Incluaea in this report are WUA functions ana related habitat inaices aefining the relationship between mainstem discharge ana chinook rearing habitat potential at 20 study (modeling) sites on the middle Susitna River. Modeling results are extrapolated from inaivillual stuay sites to describe the response of Juvenile chinook habitat within a number of different suD- environments of the midale Susitna River. Conventional methods of extrapolating WUA in single channel rivers oased on the concept of continuous homogeneous suDsegments represented by inaiviaual modeling sites are not applicable to large oraiaea rivers like the the Susitna River aue to large spatial variations in hyaraulic ana morphologic character. Aaseruae et al. (1985) aiscuss thls proolem further. Consequently, inves- tigators concentrated on sampling smaller areas of the miaale river possessing relatively uniform yet comparatively aistinct ~ydrologic, hydraulic ana water clarity charcteristics. This sampling aesign promptea 8 I I I I I I I I I I I I I I I I I I I the development of an extrapolation methodology, first introduced by Steward ana Trihey (1984), which weights WUA indices developed for each modeling site according to the proportion of the middle reach possessing similar hydrologic, hydraulic ana water clarity attributes. This approach focuses on the characterization of fish haDi tat on the suDenvi ronmenta 1 scale in order to overcome problems associated with the large degree of environmental variability in the middle Susitna River. Stratifying the river into subenvironments ana identifying the relationship between streamflow and fish habitat at this level increases our confidence in the applicability of these results to the river as a whole. Within the overall framework of the Susitna aquatic habitat assessment program, habitat modeling results obtained for individual subenvironments are particularly appropriate since related studies of juvenile fish dis- tribution were conducted at this level (Hoffman 1985). An evaluation of habitat modeling results in combination with fish utilization data will permit an accurate assessment of rearing habitat response to natural ana project-induced changes in streamflow for the entire middle river segment. Figure 3 illustrates the primary steps in the extrapolation analysis. An outline of the data requirements ana steps which comprise the methodology follows in order that the reader gain an appreciation of the utility of the rearing habitat response curves. The results of applying the full extrapo- lation analysis to existing flow regimes will De detailed in Volume 11 of the 1nstream Flow Relationships Report, sct1edulea for release by EWT&A in December 1985. 9 Quantification Quantity surface areas of individual channel branches in the middle Susitna River for each flow for which aerial photography is available to determine the surface area response to mainstem discharge.

Flow chart indicating steps followed in the extrapolation of site-specific juvenile chinooK habitat indices to the entire middle Susitna River. 10 2.0 METHODS 2.1 Habitat Characterization of the Middle Susitna River 2.1.1 Study Site Classification For the middle reach of the Susitna River, Klinger and Trihey {1984) identified six subenvironments, on the basis of water source and morphology, which they termed habitat types: mainstem, side channel, side slough, upland slough, tributary, and tributary mouth. Rearing habitat modeling sites were initially selected to conform with the concept of aquatic habitat types. The degree to which t:-tese habHat types are uti- lizea by juvenile salmon as well as their susceptibility to project impacts determined the extent to which they were represented in modeling studies. Of the large number of locations sampleu for juveniles in 1981 ana 1982, significant numbers of chum, sockeye, and chinook salmon were found in tributary, siae channel, side slough ana upland slough locations. Chinook salmon utilization of these habitat types is summarized in Figure 2. Recognizing that rearing haOita~ in tributaries will prooaoly no: De affected by project operation, investigators excluaea this habitat type from modeling studies. Juvenile salmon utilization of mainstem ana tribu- tary mouth areas was juagea insufficient to warrant intensive study. The sites chosen for modeling studies of juvenile chinook habitat are iaenti- fiea by river mile ana bank orientation {Lana R denote left and right Dank looking upstream) in Figure 4. 11 Figure 4. 4111 of JfllyCrHII I J6 ~~(VI )l I li.OL (I V ) G AGE 'S292 000 JUVEN ILE CHINO OK H A B I TAl MODEL I NG SITES (MIOO LE SU SITNA R I VER ) 0 MILES J uvenile chinook habitat moaeling sites in the miaale Susitna River.

J.2 2.1.2 Representative Groups While the haDitat type concept of Klinger and Trihey (1984) is useful in the identification of attributes characterizing a particular location within the middle river at a given time, the static quality implicit in the concept makes it less practical as a means of stratifying the river for extrapolation purposes. The results of the habitat modeling analyses are WUA forecasts for sites which frequently transform from one habitat type to another ov~r the range of evaluation flows. Juvenile chinook habitat distribution and quality is highly dependent upon these transformations and the progressive physical changes which attend them. In order that the dynamic and site-specific nature of rearing habitat response to a constantly changing aquatic environment be acknowledged by the extrapolation methodology, an alternate means of stratifying the middle river was developed. The concept of representative groups as a further set of distinct subenvironments of the middle river and the criteria used by Aaserude et al. (1985) to define them ensures that the modeling sites are truly representative of the portions of the river they are supposed to characterize. Accurate forecasts of the response of juvenile chinook to natural or imposed changes in flow regime require that this condition De satisfiea. Aaserude et al. (1985) delineatea 172 specific areas of the mieldle river from aerial photography interpretation anel fielel verification studies. Specific areas formerly assignea to four habitat types (siele channel, siele slough, upland slough, anct in some Cdses mainstem habitats) were Clivictea 13 among ten representative groups, each characterized Dy unique ana readily identifiaDle comDinations of flow-related attriDutes. Representative groups ana the primary hydrologic, hydraulic ana morphologic forms ana processes which distinguish them are summarized in TaDle 1. Each modeling site is associated with a corresponding specific area; from an analysis of aerial photography ana reconnaissance level fiela data, a moaelea specific area mdy also be aeterminea to De representative of several non-modeled specific areas within the same representative group. llithin the framework of the extrapolation methodology, the collection of moaelea ana non-moaelea specific areas which comprise a particular repre- sentative group may be thought of as a discontinuous (i.e., spatially discontinuous) yet homogeneous suosegment of the river. Figure 4 indicates the representative group designation of each rearing habitat modeling site. Because the delineation of representative groups occurrea suDsequent to stuay site selection ana aata collection, some representative groups ao not possess specific areas in which modeling stuaies were conauctea. In particular, specific areas which aewater at relatively high mainstem discharges (Group VIII) ana mainstem areas which remain shoal-like at most evaluation flows (Group X) are not represented Dy juvenile chinook habitat modeling sites. The re mainder of the representa- tive groups have at least one specific area with an associated modeling study site. ,.his fact is important since the aDjective is to extrapolate haDitat inaices from specific ar~as with modeled sites to non-moaelea specific areas, assuming that modeling sites generally reflect the haDitat character of non-moaelea area5 within the same representative group.

No attempt was maae in the present analysis to charac- terize rearing haoitat at specific areas incluaea in Group X, However, future derivation of acceptable habitat response curves for this group is feasible through moaification of airect input hyaraulic /haoitat moaels aevelopea for spawning chum salmon (Hilliara et al. 1985) Important criteria used to partition specific areas into representative groups are the type ana rate of change in hydrologic character aocumentea for the specific areas. The hydrologic component of the methoa usea by Aaserude et al. (1985) to stratify the middle Susitna River focuses on the systematic transformation in habitat type of specific areas within the 5,100 to 23,000 cfs flow range. For example, as flows recede mainstem areas frequently become shallow water shoals, ana siae channels may transform into siae sloughs~ Doth naoitat types may eventually aewater as flows aecrease further. The emphasis on habitat transformation acknowleages the transient nature of riverine habitat availability ena aistrioution. The aichotomous key in Figure 5 aelineates the eleven habi- tat transformation categories aerivea from an evaluation of the 172 speci- fic areas ana eight streamflows for the miaale river. Note that the fina l categories apt)roximate the original "habitat type'' designations usea oy Klinger ana Trihey (1984) ana ADF&G (1983). Two important modifications to the haDitat type classification system are the inclusion of shoal habitat and the presence/absence of upwelling. Shoals are areas whicn at high flows are visually inseparable from aajacent mainstem or side channel areas.

Upwelling groundwater, usually aiscernable in aerial photos by the presence of clear water, is accentuated in the classification step of the extrapola- tion methodology because of its pronounced effect on the distribution of juvenile ana aault salmon within the middle Susitna River. Using habitat types present at 23,000 cfs as a point of reference, site- specific habitat transformations have been aefi nea for sever a 1 ai scharges of 18,000 cfs ana less. The sequential changes in habitat type observed within this flow range offers a powerful tool with which to combine specific areas into representative groups. Other hydrologic parameters used with varying degrees of confidence to cluster specific areas into representative groups are breaching flow, cross-secti ona 1 profi 1 es of the head berm ana adjacent mains t .. :n channe 1, ana up we 11 i ng. Of the hydraulic variables examinea oy Aaserude et al. (1985), mean reach ve 1 oci ty under breached conaiti ons was cons ide rea the most appropriate for classifying specific areas within the middle Susitna River. Unfortunately, the relatively low flows (8,000 -11,000 cfs) at which field sampling was conducted precluded standardization of mean rea~h velocities on the oasis of a common flow or transformational state. ~lean reach velocities ·t~~ere unavailaole at sampling flows for two-thirds of the specific areas delineated in the middle Susitna River; the majority of the sites were unbreachea during reconnaissance field studies. Nonetheless, the velocity data collected was usea to further refine trdnsformation category definitions. 18 Of more practica 1 va 1 ue in the oevel opment of representative groups were channel morphology inelices oeriveo from aerial photo interpretation ana on- site visits in the field. Specific areas within the miaale reach exhibit sufficient s1m1larities in plan form to provioe a theoretically attractive means of grouping sites together. Use of channel geometry, sinuosity, length-to-width ratios ana related morphologic indices to classify specific areas according to representative group is justified by the repetitiveness of similar channel features within the miadle river segment. 2.2 Quantification of Surface Areas Although each specific area is assigned to the same representative group for a 11 flows of interest, the peri meter ana therefore its surface area varies with discharge. Furthermore, both the absolute size ana the rate of change in surface area varies between specific areas. Successful applica- tion of the extrapolation methodology requires that the surface area response to streamflow of inaiviaual sites be quantifieo since the amount of rearing habitat available within a specific area is aepenaent on its areal extent at different flows. The total surface area of each specific area in the miaale river has Deen estimatea for mainstem aischarges of 5,100 , 7 ,400, 10,600, 12,500, 16,000, 18,000, 23,000 cfs using ai gi ta 1 measurements on 1 inch = 1,000 feet sea 1 e aerial photography. The digitizing methods are aescribe<l by Klinger ana Trihey {1984). Surface area estimates were use<l to aaJust WUA estimates at Doth moaele<l an<l non-moaele<l specific areas , as <lescribe<l in Section 2 .4 Del ow. 19 2.3 Physical Habitat Modeling Studies 2.3.1 Overview of Moaeling Techniques The quantitJtive asse ssment of juvenile chinook rearing habitat response to streamflow in the middle Susitna River is basea on investi gations conauctea by ADF&G and EWT&A between 1982 and 1985. Sufficient aata were collected to moael chinook rear i ng habitat potential at 20 moaeling sites typical of 9 of the 10 representative groups which characterize the middle Susitna River. These stuaies utilizea two data intensive modeling techniques: 1) the Resident Juvenile Habitat (RJHAB) moael aevelopea by ADF&G; and 2) the Physical Habitat Simulation (PHABSIMl System aevelopea Dy the Instream rlow ana Aquatic Systems Group of the U.S. Fish ana Wildlife Service. Data requirements ana sampling methods employea by the two models are s i milar, ana moael parameters ana stanaara output variables are identica l (Figure 6). The major differences between RJHAB ana PHABSIM moaeling approaches relate to the resolution of input ana output aata ana the tech- niques usea to process these data. The RJHAB model generates surface area ana WUA output only for those discharges for which hydraulic inf:Jrmation was collected . The PH ABS I M modeling system incorporates hydraulic mo dels which may be usea to forecast synthetic hydraulic data for any stream f l ow with i n an acceptabl e calibration range . These data serve as inpu t to a program (hABTAT l wh i c h calculates wettea s urface area ana various habitat inai r es f or the moaeling site.

The availability of areas characterized by suitable combinations of these variabies "aries directly with changes in streamflow. The primary objectives of Doth habitat moaels are to quantify the distr i bution of various combinations of these habitat variables within a representative segment of stream ana to aescribe this distribution in terms of its usability or potential as rearing hab i tat for juvenile chinook.

The surface area associated with each cell extended halfway to adjacent verticals ana transects {Figure 8). In contrast to the RJHAB model, the field aata obtained in the PHABSIM analysis are used to calibrate a hydraulic model capaDle of forecasting depth-velocity combinations for each cell at unsampled aischarges. Two types of hydraulic moaels were :.~sea for this purpose, depending primarily on hydraulic conaitions at the study site. The IFG-2 moael is a water surface profile type moael Dasea on the Manning equation ana the principle of conservation of mass ana energy {Milhous et al. 1984). Data requirements for the IFG-2 model include a single set of velocity aata ana several measurements of transect water surface eleva- tions. Moael calit>ration involves iterative adjustments of Manning 's n values until agreement Detween ot>served ana predicted water surface e leva- tions is ot>tainea. Once reliat>ly calibrated, the IFG-2 model may De used to predict velocities within each cell across the transect at different discharges. The sec ond type of model usea to simulate hydraulic data in rearing hat>i tat investigations was the IFG-4, which employs linear regression analysis to 25 predict aepth ana velocity as a function of discharge for each cell. The IFG-4 model requires a minimum of two hydraulic data sets but is oetter suitea than the IFG-2 mo<lel for simulating rapialy variea flow conditions (Trihey ana Baldrige 1985). Estes ana Vincent-Lang (1984), Hale et al. (1984), and Hilliard et al. (1985) provide further information on hydraulic data collection ana analytical proceaures. 2.3.3 Habitat Suitability Criteria The next stage in the RJHAB ana PHABSIM moaeling process requires that habitat suitaoility criteria be developed for the species/life stages of interest. Habitat suitaoility criteria (curves) inaicate the preference of a fish for different levels of a particular habitat variaole; su i tability curves are neeaea for each physical habitat variaole incorporated in the habitat mo<lels. ihe cover, velocity ana depth suitability criteria used in this stuay to evaluate ch~nook rearing habitat potential in the m1dale Susitna River are basea primarily on field observations of juven1le chinook aensities in siae channel ana s ide slough areas of the middle Susitna River (Suchanek et al. 1984). EWT&A ana wee (1 985 ) and Steward (198 5 ) aiscuss these data with regard to their appl i cability to mainstem, side c hanne l ana si<le slough naoitats.

The frequency and auration of this condition depends on the elevation of the thalweg at the head of the site relative to the water surface elevation of th~ adj~c~nt mainstem. Site flow versus mainstem discharge relationships were usea to determine when clear ana turbid water velocity and cover criteria were to be applied. Rearing salmon use cover to avoid predation and unfavorable water velocities. Instream oojects such as submerged macrophytes, large substrates ana organic debris, ana overhanging vegetation 1n near shore areas can previae cover for juvenile chinooK salmon. Instream object cover in most rearing areas of the mid~le Susitna River is proviaed by larger streamoea materials, rrimarily rubble (3-5 inch diameter) and boulder ( >5 inches) size substrates. The cover suitability criteria presented in Figure 9 and Table 2 suggest that juvenile chinooK tend to associate with some form of object cover in both clear ana turbid water habitats. Preference gen~rally increases in proportion to the percentage of object cover present, particularly under clear water conditions. The different preferences for the same type ana percent of object cover inaicatea by the clear ana turbid water suitability criteria are due to the utilization of turbiaity as cover by rearing chinooK. Dugan et al. (198 4) documented higher densities of chinooK in breached, turbid water side channels than were found at the same sites unaer nonbreachea, clear water conai ti ons. Th1s disparity was most pronounced at sampling sites possessing minimal object cover. 30 Table 2.

Proviaea that other microhabitat conditions are suitable, juveniles tend to prefer depths exceeding 0.15 feet to an equal aegree. This observation has been corroborated in other habitat utilization studies of juvenile chinook salmon (Steward 1985). A distinct preference by juveniles for low velocities under turbid water conditions .,.,as noted by Suchanek et al. (1984). Turbid water habitat suitability criteria identify optimal velocities in the 0.05 to 0.35 fps range, as compared to 0.5 to 0.65 fps indicated by clear water velocity criteria (Figure 11). The preference for lower velocities in areas of high turbidity may be twofold: 1) a lack of visual cues necessary to maintain position in faster currents, ana 2) a decrease in the number of drifting prey items captured at higher velocities (Milner 1985). 2.3.4 Habitat Model Response Variables The RJHAB model was modified slightly in order that the methods of calculating variou ~ i ndices of habitat potential, including WUA, and wetted surface ~reas were consistent for all modeling sites. Wetted surface area (WSA) estimates ba~ed on RJHAB and ?HABSIM modeling approaches were com- puted by summing the surface a:-eas of watered cells within the modeling site (Table 3). Flow related increases in wetted surface area at RJHAB sit2s were apportioned among mid-channel cells of the sites since the dimensions of the area represented by bank cells remained essentially unchanged for all flows. At study sites modeled with IFG-2 or IFG-4 32 w w Table 3 .

Hence, the cumulative surface area of the IFG moaeling sites increased through the addition of new cells along the shore 1 i ne. The composite suitability of each cell within the RJHAB ana lFG moaeling sites was determined by multiplying the individual suitability values associated with prevailing velocity, aepth and cover conditions (Table 3). This method of calculation implies that the physical habitat variables evaluated by the models are assumed to be independent in their influence on habitat selection by juvenile chinook. Weighted usable area is computed for each cell by multiplying the Cc!ll's composite suitability by its sur- face area. The sum of the cell WUAs obtainea for a given discharge yields the moaeling site WUA; when plottea as a function of discharge, the modeling site WUA curve indicates the response of usable rearing habitat to changes in streamflow. Haoitat simulation results include WUA ana WSA estimates for each study site for mai nstem discharges ranging from 5,000 to 35,000 cfs as measured at the USGS Gala Creek gaging station. In order to facilitate comparisons between moaeling sites, WSA is expressea in units of square feet per linear foot of stream. WSA is therefore proportional to the mean width of the modeling site. These units are less satisfactory for comparisons of 1o'IUA since usable habitat at a site is a function of surface area weightea by the suitability of its physical habitat attributes. An interpretation of habitat availability shoula not be made without reference to the total wetted surface area of the site. As an example, consider two study sites 34 possessing relatively equal amounts of weighted usdble area; the smaller site, particularly where there is a large disparity in size, possesses a greater amount of usable habitat relative to the prevailing wetted surface area. Therefore, a more meaningful index of habitat avai 1 ~~~ 1 i ty is the ratio of WUA to WSA, which is de>ignated the Habitat Availability Index (HAI). In the context of the extrapolation analysis, the Habitat Availability Index has the added merit of being unitless. Assuming that the HAI of a modeling site is representative of the associated specific area (i.e., both possess the same frequency distributions of cover, velocity and depth), the WUA of the specific area is equa 1 to the product of the HAI and the tota 1 surface area of the specific area. Total surface areas are known, as discussed in Section 2.2, and therefore a flow-dependent habitat response curve may be derived for any specific area represented by a modeling site. The HABTAT pr·ogram of the PHABSIM modeling system and the RJHAB model were modified to compute the Gross Habitat Area (GHA) for each discharge of interest. The GHA is the cumulative (unweighted) surface area of cells possessing non-zero WUA values within a site. Gross Habitat Area is impor- tant because it represents the maximum area of rearing habitat available. Two other habitat response indices, the Habitat Distribution Index (HD!) and the Habitat Quality Index (HQI) are calculated by the following fonnulas: and HDI (~) = GHA/WSA x 100 HQI (%) = WUA/GHA x 100 35 The use of HOI and HQI indices partially overcomes a major criticism of most WUA-based interpretations of habitat potential, namely, that WUA is a quantification of the amount of suboptimal habitat within a stuay site expressea as an equivalent amount of optimal habitat. In other words, a cell with a surface area of 100 sq. ft. and a joint preference factor of 1.0, that is, optimal cover, velocity and depth conditions, is assumed to provide as much usable habitat as an area ten times its size which possesses a joint preference factor of 0.10. Although flow-related changes in the composite suitabOity of individual cells (i.e., at discrete loca- tions within the modeling site) were not ev l luate<l, we examined relation- ships Detween a modeling site's weighted usable area, gross habitat area and wetted surface area over a range 0f discharges to gain an understanding of probable changes in habitat quality within cells containing usable habitat. Surface areas ana habitat indices were simulated for site flows corresponding to mainstem flows ranging from 5,000 to 35,000 cfs at Gold Creek. Of the 20 study sites investigated, six were modelea using the RJHAB model and15 were moaele<l using the PHABSIM modeling system. One study site, 132.6L (Representative Group Ill), was modeled using Doth RJHAB ana PHABSIM techniques. ln most instances, WSA, WUA and HAl values for unobserved site flows (in the case of RJHAB models) or flows lying outside the recommended extrapolation range of the hydraulic models (a frequently encountered situation in PHABSIM applications) were estimated by interpola- tion and trend analysis techniques (Hillia~a et al. 1985). I n fitting curves to data points forecast by the habitat models, reference was maae to aerial photographs and site-specific channel geometry ana oreaching flow information. 36 2.4 Extrapolation of Moaeling Results to Non-moaelea Specific Areas Whereas the general habitat characteristics of a moae l ing site may ce assumea to ce representative of the associatea specific area, the same combination ana quality of habitat attributes may not oe fo und i n other specific areas, even those classified in the same representative group . Aaseru<le et al. (1985) concluded that variations in structura l characteri s- tics, including several attributes known to affect the quality of juvenile chinook rearing habitat, are common among specific areas of the same repre- sentative group. These differences are significant enough that direct transfer of WUA functions from modeled to non-modeled specific areas is considered impracticable. For this reason, Structural Habitat Indices (SHls) were developed from field data in order to rank spec i fic areas within the same representative group according to their relative structural haoitat quality. As inaexed cy SHI values, specific areas are eva l uatea on the oasis of six variables: 1) dominant cover type, 2) percent cover, 3 ) dominant substrate s i ze, 4) substrate emoeddedness , 5) channel cross sec- tional geometry, and 6) ripar i an vegetation. These variables were weighted accoraing to their relative importance to juvenile c hinook salmon. Fo r each variable , specific areas were placed in one of f i ve descriptive cate- gories, ranging from "non-existent" to "excellent" in quality . Each variable category received a corresponaing numerical rating f a cto r . A single SHI value was calculated for each specific area, i ncluding t hose containing moaeling sites, oy summing the products of variable weighting ana rating factors. For further details concerning the collection and synthesis of <lata into structural habitat indices, see Aaseru<le et al. ( 1985). 37 In this, the integration step of the extrapolation methodology, Habitat Availability Indices (HAls) derived for the modeling sites are used to estimate juvenile chinook WUA for each specific area of the miaa~e Susitna River. As discussed above, the amount of usable rearing habitat at a specific area containing a modeling site may be calcul ated by multiplying the modeling site's HAl value (i.e., the WUA:WSA ratio obtained as moael output) by the wetted surface area of the speci fie area. For each discharge, this calculation can be represented as WUAsa= HAims,sa x WSAsa where the subscripts ms ana sa refer to the modeling site ana the specific area within which it is found. As pointed out earlier, HAl values determined for the modeling site are assumed to be applicable to the entire spec i fi c area. If it were reasonable to assume that the HAl response curves for all specific areas within a representative group were identical, then WUA values for non-modeled specific areas within the same group could be calculated by the above equation using a single HAl function. The structural habitat aata of Aaserude et al. (1985), as well as the ~oaeling results presented in this report ao not support this assumption. Between- site variations in rearing habitat availability appear to result from dissimilarities in channel geometry (which are reflected by differences in breaching flows ana the rate of change in WUA ana WSA) ana structural habitat quality (as indexed by SHI values). Therefore, each specific area of the middle Susitna River is assumed to possess a unique HAl curve which may nonetheless be patterned after the modeling site within the same 38 representative group having the most similar hydrologic, hydraulic, and morphologic attributes. Specific areas within a representative group with more than one modeling site are divided between modeling sites on the basis of their SHI values. Thus, each modeling site may ue considered representative of a subgroup of specific areas. HAl curves are developed for non-modeled specific areas by modifying the HAl functions of associated modeling sites using information obtained in the classification ana quantification steps of the extrapolation analysis, i ncl ucti ng: 1) breaching flows to normalize HAl functions on the discharge axis; and 2) structural habitat i ncti ces to adjust for eli fferences in the quality of usable rearing habitat. Table 4 summarizes breaching flow and SHI information usea in the development of HAl curves for non-modeled specific areas within Representative Groups I through IX. The discharge at which the head berm of a specific area is breached is the dominant hydrologic variable affecting the availability of chinook rearing habitat. As will be demonstrated later, thr.: vast majority of juvenile chinook HAl functions obtained for the middle Susitna River modeling sites exhibit a maxima just to the right of the breaching flow on the discharge (horizontal) axis. To develop an HAl response curve for a non-modeled specific area, the HAl curve obtained for the associated modeling site is shifted left or right on the abscissa depending on whether the breaching flow for the non-modeled specific area is lower or higher than that of the moaeling site. The distance moved is equal to the difference in the sites' breaching discharges. This lateral shift, diagrammed in Figure 12, identifies the horizontal coordinates of the HAl curve for the non-modeled specific area. The lefthana curve in Figure 12 represents HAl values 39 Tool• 4 . lla1nst .. or.Kft1ng atocftorg•s ana •tr11Ct11ral lleOUAt 1ft01ces (SHI) oate•·•1neo tor •o•ciiiC ar~u w1tn1n tfte ••oo l~ 51111 till R 1 war .

The curve on the r i ght is an HAl function obtained for a relatea non-moaelea specific area (also hypothetical) from the same representative group. Structural habitat indices are used to determ i ne the magnitude of the HAl response to flow at a non-moaele<1 specific area (i.e., to "fix" the location of the HAl curve with respect to the vertical axis) as illustrated in Figure l2b. For each discharge, the following calculation is made : HAlsa = HAlms x (SHlm 5 /SHlsa) In this case, the subscript ms refers to the modeling site whose HAl function has been adjusted using the breaching flow of the non-modeled specific area, identified by the subscript .i.!· The non-modeled specific area in Figure 12c HAl curve has been shifted to the right and downward to account for the higher breaching flow ana the lower structural habitat quality of the non-modeled site r ..::lative to the modeled site. An HAl response curve derived in this fashion may be multiplied by wetted surface area estimates to calculate WUA values for each flow of interest. Preliminary HAl functions have oeen developed for all middle Susitna River specific areas ana appear in Section 4.0 of this draft report. 42 2.5 Application of Habitat Modeling Results The synthesis of aata obtainea in the classification, quantification and simulation steps of the extrapolation analysis will provide estimates of chinook rearing habitat for 172 specific areas within the middle Susitna River. Preliminary surface area measureme1ts have been obtained for speci fie areas in Representdtive Groups I through IX, and aggregate WUA curves for juvenile chir.ook salmon are presented herein for these subenvironments. In regara to the rearing habitat potential of different representative groups, the relative significance of aggregate WUA functions in future decisions will likely oe influenceu by data concerning )resent and prospec- tive utilization by juvenile chinook salmon under natur ·al and with-project flow regimes. An assessment of the relative i mportarce of the aifferent representative groups in terms cf their utilization by rearing chinook salmon will appear in Volume II of the Instream Flow Relationships Report. When coupled with information relating to fooa availaoi· ity, water tempera- ture, suspenaea sediment ana other environmental fac:ors, the aggregate physical habitat response functions will allow for con•:lusions and recom- mendations at the 1il anagement level. 43 3.0 RESULTS 3.1 Representative Group 1 The 19 specific areas within this group include all upland sloughs occuring in the miaale Susitna River. Except during flooa stage, these sloughs are connected to the main channel only at their downstream ena. In aaaition to high breaching flows and low turbidity levels, typical features of specific areas in Representative Group 1 include low velocity pools of greater-than- average depth separated by short, higher velocity riffles. Clear water enters these sites via seepage or tributary inflow and maintains relatively stable base flows under non-breached conditions. Substrates are frequently homogeneous over large areas ana are often characterized by fine silt/sana sediments overlaying cobble materials. Cover is usually provided by over- hanging ana emergent vegetation. These sites are usea only to a small extent by juvenile chinook salmon (Marshall et al. 1984). Specific areas assigned to Representative Group 1 are represented Dy two RJHAB modeling sites: 107.6L and 112.5L. Photographs of these sites when mainstem discharges were 23,000 ana 16,000 cfs are presentea in Plates A-1 ana A-2 (Appendix A). For much of its length, Site 107.6L is a low graai ent, narrow meandering stream. At mai nstem ai scharges above 20,000 cfs, the turbid backwater area at the slough mouth advances upstream and inundates lower sections of the site; this phenomenon accounts for the marked relative increase in wetted surface area indicated in Figure 13. Usable c hinook rearing habitat at Site 107.6L aoes not respond dramatically to increases in wettea surface area, as evidenced by the WU A ana HAl curves 44 1511 tl!5 t20 -... 10!5 -' ... 90 -. 7!

A-Wetted surface area (WSA) a~d weighted usable area (WUA). B-Habitat availability index (HAll 45 shown in Figure 13. WUA at this site gradually increases at higher flows due to the reduction in water velocity anu water clarity caused by rising backwater. Water velocities ranging up to 0.8 fps are common at transects upstream of the backwater pool. Therefore, under clear water conditions nearly ideal velocities exist for juvenile chinook. A silt suostrate is dominant, which affords little cover value for juvenile chinook, resulting in a low composite suitability for most cells within the site regardless of the suitability of their depths and velocities. As the extent of the backwater increases, velocities in these cells decrease to 0.0 fps, slightly reducing suitability with respect to this habitat variable, but turbidity levels increase, yielding a higher overall suitability (the weighting factor associated with the Mno coverN class of cover using turbid water suitability criteria is 0.31, compared to 0.01 for clear water criteria}. When coupled with an increase in surface area, this leads to the slight rise in WUA observed at higher flows. However, because the rate of change in WSA is so great relative to the change in WUA, the proportion of the site containing usable rearing habitat declines as flows increase. HAl s decrease from 11.9 percent at 5,000 cfs to 5.4 percent at 26,000 cfs. In contrast to Site 107.6L, very little response in WSA, WUA, and HAl to changes in mainstem discharge were observed at Site 112.5L (Figure 14). The latter site is an upland slough with steep banks which prevents large changes in surface area as site water surface elevations change (Plat.e A- 2). As a consequence, physical habitat conditions within this site remain relatively constant and little variation in WUA and HAl results from main- stem flow fluctuations below 35,000 cfs. Slight inconsistencies in ADF&G field data required that an average HAl value (4.2 percent} be used to back 46 t2ll tOI • -. 4J ... -' . 72 4J -c:r • ~ ..

Values derived for these habitat indices were comparable to those recorded for Site 107 .6L. Specific areas assigned to Representative Group I are former side channels and side sloughs that have become increasingly isolated over time from the mainstem owing to long-term channel activity. Due to the infrequency of breaching events, the primary response in habitat character at these sites results from backwater effects at the upland slough/mainstem interface . Differences between specific areas are related primarily to the extent of backwater areas, and secondarily to the presence or absence of riparian and instream vegetation. Variations in local runoff resulting from precipitation may also affect short-term habitat availability and quality. Of the two modeling sites investigated, Site 107.6L is located within a specific area which is representative of 8 of the 19 specific areas classi- fied in Group I, based on between-site comparisons of Structural Habitat Indices (SHis) obtained from Aaserude et al. (1985). Site 112.5L may be considered representative of the remaining specific areas, each possessing an SHI of 0.56 or greater. HAI functions were derived for modeled and non- modeled specific areas associated with each of the modeling sites and are presented in Figures 15 and 16 (see also Appendix B). These HAI curves were not adjusted laterally on the discharge axis since the specific areas within Representative Group I are breached at extremely high mainstem discharges. Differences in habitat availability between specific areas are assumed to be due to dissimilarities in strtJctural habitat quality.

The product of flow-specific HAl ana WSA values are estimates of the to·tal amount of WUA (in square feet) present at a particular site for mainstem flows ranging from 5,000 to 35,000 cfs. Aggregate WSA ana WUA values were obtained for Representative Group I by summing individual specific area WSA and WUA forecasts. The results of these calculations are presented in Figure 17. The overall response of juvenile chinook habitat for Group I sites is influenced by changes in backwater-related surface area and by the relative constancy of HAl values, particularly at lower flows. WUA tends to increase slightly as flows increase from 5,000 to 1fi,OOO cfs; rearing habitat is maximal at the latter flow. Rearing habitat potential remains fairly constant between 16,000 and 35,000 cfs. It should be noted that the total amount of rearing habitat proviaed by Group I is small in comparison to other Representative Groups due to their comparatively low surface area and HAl values recorded for its inaiviaual specific areas. 3.2 Representative Group II Associated with this group are modeling sites 101.4L, 113.7R, 126.0R and 144 .4L. These sites are associated with siae sloughs having moderately high breaching flows ( > 20,000 cfs) ana enough upwelling groundwater to keep portions of the sites ice-free during the winter months. Side sloughs classified in Representative Group II were found to contain significant 51 REPRESENTATI VE GROUP I A 2.00 ~----------------------, .u !.80 l .... 1.60 l : !.40 ij 0 !.20 Ill ~ !.00 ~ .81' --- < .411 UJ MSA e .60 l ~ .20 0 . 00 -t--r==::;::=::;:==;::=::;:=::::;:==:::;;:=:=::;::::=-~llli~A-_j l I 200 180 ..., .... 160 c:r Ill 1411 .... 0 120 Ill "0 tOO c n:J Ill eo ~ 0 J:::. 60 ..., 411 < =:J X 20 0 Figure 17. 0 41100 8000 12000 16ooo 20ooo 24ooo 2eooo 320oo 36000 •oooo MAINSTEM DISCHARGE (CFSJ B 0 41100 eooo 12000 t6ooo 20000 2•ooo 28000 320oo 36ooo •oooo MAINSTEM DISCHARGE (CFS) Aggregate response of A -wetted surface area (WSA) ana B - chinook rearing habitat potential (WUA) to mainstem dis- charge in specific areas comprising Representative Group I of the middle Susitna River. 52 numbers of juvenile chinook during the growth season, particularly in their breachea state {Dugan et al. 1984). The 27 specific areas incluaea in this group are typically oxbow channels separated from the mainstem by large, vegetated islanas or gravel bars. When breached, these channels convey only a small percentage of the total mainstem flow. They are characterized further by relatively high length- to-width ratios ana lower graaients than are found in the adjacent main- stem. Cross-sections vary from relatively broad, uniform ana rectangular in shape to narrow, irregular ana v-shaped in profile. Head berms generally fall in the former category. Backwater areas occur at the mouths of most specific areas within Group II but their effects on hydraulic conditions ana therefore juvenile chinook habitat are not as extensive as those observea for uplana sloughs since siae sloughs possess slightly higher graaients. Substrates range from silt ana sand in backwater areas to I'Ubble/cobble/boulaer throughout the rest of the site. These sites tena to possess abunaant macrophytic vegetation. Aerial photography indicating the general features of modeling sites 101.4L, 113.7R, 126.0R, ana 144.4L ana their associated specific areas at 23,000 ana 16,000 cfs are presented in Plates A-3, A-4, A-5, ana A-6 (Appendix A). The appearance of these sites does not change appreciably at mainstem flows below 16,000 cf ~. Response curves for wetted surface area (WSA) ana habitat indices (WUA, HAl) developed for the four ~odeling sites within Group II exhibit strong similarities in appearance due to the aominant influence of shared hydro- logic, hydraulic ana morphologic properties (cf Figures 18-21).

B -Habitat avai 1 abi : i ty i naex (HAll 57 non-breached state, wetted surface areas remain relatively constant, responding primarily to local runoff ana upwelling conditions. Following breaching, rapid increases in WSA occur in response to further changes in mainstem flow. Increases in WSA are attenuated as flows approach bank full levels. Juvenile chinook WUA values simulated for Group II modeling sites are generally constant until the sites are breached, whereupon large increases occur in response to incremental changes in site flow. The amount of usable rearing habitat tends to peak shortly after the head berms are overtopped. This relatively sudden ana rapid increase in juvenile chinook habitat results from a combination of factors: 1) the rapid accrual of wettea surface area, 2) the enhanced cover value provided by higher turbidities, ana 3) the preponderance of velocities falling within the optimal preference range for juvenile chinook. In general, the magnitude of the WUA increase is proportional to the increase in wetted surface area possessing suitable velocities. Site velocities, however, soon become 1 1 mi ti ng in mi d-channe 1 areas fo 11 owing breaching, 1 eadi ng to a reduction in rearing WUA at higher flows. On the basis of limited gross habitat (GHA) ana habitat quality (HQil data obtained for Site 126.UR (Figure 20), usable rearing habitat appears to be more uniformly distributed ana of better quality at flows associated with the ascending left hand limb of the WUA curve than at non-breached or high mainstem discharges. Under non-breached conditions, unsuitably shallow depths often occur in riffle areas of the site, resulting in slightly lower HOI values. Although surface area ana habitat indices for Site 126.0R were not extrapolated to flows exceeding 35,000 cfs, it is likely that juvenile 58 chinook habitat becomes more restricted to peripheral areas as mid-channel velocities increase. Aaserude et al. (1984) report identica l structural habitat (SHI) values for modeling sites 113.7R and 126.0R; these sites collectively represent 15 of the 27 specific areas within Group II. Breaching flows were used to divide these 15 areas among the two modeling sites. Specific areas breaching at flows exceeding 28,000 were grouped with Site 126.0R, which is overtopped at 33,000 cfs. The 13 other specific areas, all breaching at 27,000 cfs or less, arf! represented by Site 113.7R, which breaches at 24,000 cfs. Site 144.4L has a higher SHI value than the other modeling sites and represents 7 of the specific areas in Group II. Site 101.4L may be considered repre- sentative of the remaini ng 5 specific areas. HAl functions are plotted for specific areas associated with each of these modeling sites in Figures 22 through 25. HAl values used to plot these curves are tabulated in Appendix B. Figure 26 depicts the aggregate WUA curve obtained by multiplying Group II specific area HAl values by their wetted surface areas and summing the results for each flow of interes~ Because of their high breaching flows, most specific areas exhibit peak HAl values in the range of 20,000 to 30,000 cfs. When adjusted by their wetted surface areas these sites yield cumulative WUA values which increase slowly at low to intermediate flows, increase more rapidly after this point and peak at 29,000 cfs. Approximately 1.2 million square feet of juvenile chinook WUA is provided oy Group II specific areas at this discharge.

Figure 26 also illustrates aggregate WSA response for Representative Group 11. 3.3 Representative Group Ill Sites l01.2R, l28.8R, l32.6L and l41.4R are all side channels which become nonbreached at intermediate (8,000 to 16,000 cfsl mainstem d i scharge levels, and transform into side sloughs at lower discharges. These modeling sites and the Group III specific areas they represent, shown in Plates A-7 through A-14 (Appendix Al, are larger and convey greater volumes of water when breached than the side sloughs discussed in the preceding section. Site geometry tends toward broad, concave cross-sections. Reach gradients are less than those measured for the adjacent mainstem, yet great enough to promote mid-channel velocities of 2 to 5 fps following breaching. Consequently, substrate is dominated by larger bed materials. Upwelling occurs sporadically within these specific areas and in a few cases may be insufficient to provide for passage between clearwater pools formed at low mainstem flows. The specific areas comprising Group I l l represent some of the most heavily utilized rearing areas in the middle segment of the Susitna River. Juvenile chinooK are fauna in these areas primarily under turbid water conditions (Dugan et a 1. 1984 l.

A fourth site, 132.6L was modeled using Doth PHABSIM and RJHAB modeling techniques appliea to separate sets of data. Results for this site are found in Figure 29. An inspection of the aerial photography (Plates A-7 through A-14, Appendix A) WSA curves developed for the modeling sites suggests a rapid response of wetted surface area to changes in mainstem discharge following breaching. This response is paralleled by changes in gross habitat area until moaerately high flows are attained, when the proportion of wetted surface area possessing usable rearing habitat falls off. Peak HOI values for the moaeling sites typically range from 95 to 97 percent. These max i ma usually occur at much higher flows than those associated with peak WUA values. Therefore, the quality of usable rearing hatli tat, as measured by the HQI index, tends to decline at higher flows; i.e., a greater proportion of the total WUA is concentrated in a smaller area within the modeling sites. This decline is caused tly shifts in velocities in the majority of cells toward the sutloptimal end of the velocity suitatlility curve. Usatlle habitat within Group III specific areas during the non-tlreachea phase is generally minimal due to a reduction in suitatlility caused tly increased water clarity. Specific areas represented tly Site 141.4R are an exception to this rule oecause of the widespr~ad occurence of suitaole depth/velocity cells. The enhanced cover conditions afforded oy increased turtlidity levels at this site are offset by a rapid decline in suitaole velocities following breaching. Of the 17 specific areas classified within Group III, 16 are represented by Sites 101.2R, 128.8R, and 132.6L. Site 141.4R is considered atypical due 70 to its larger size and discharge under non-breached conditions. Therefore, the only specific area assigned to this modeling site was the one in which the modeling site was found. Modeling results for Sites 101.2R and 132.6L were used to develop specific area HAI functions for 7 and 5 specific areas, respectively. Site 128.8R was used to represent 4 specific areas possessing relatively poor structural habitat quality. Figures 31 to 34 illustrate HAl functions derived from modeling site habitat data and underscore the singularity of the habitat response to flow at Site 141.4R. HAI curves developed for the remainder of the other modeling sites in this representative group exhibit a strong unimodal peak in HAI following breaching, whereas the HAI response to increasing dis- charge at Site 141.4R is to progressively decrease for reasons stated above. A com pari son of the magnitudes and shapes of the WSA, WUA and HAI curves derived for Site 132.6L (Figure 29) suggests that the RJHAB and PHABSIM modeling approaches yield similar results. The RJHAB method appears well- suited to smaller channels where cross-sectional profiles (i.e., velocity and depth ctistrit>utions) ana cover characteristics are relatively homo- geneous. We recommend limiting the use of RJHAB moaeling techniques primarily to baseline evaluations of fish habitat in lotic subenvironments meeting these constraints. The aggregate WUA function derived from individual rearing habitat response curves for specific areas in Representative Group III exhibits a pronouncea peak in the vicinity of 15,500 cfs (Figure 35).

This marked increase in usable habitat is directly attributable to the recruitment of side channel habitat within the 9,000 to 12,500 cfs flow range; 13 of the 17 specific areas which comprise Group III breach in this range (refer to Table 4 for site-specific breaching flows). After peaking at 15,000 cfs, juvenile chinook habitat gradually declines to 0.9 million square feet at 26,000 cfs and remains at this level through 35,000 cfs. Decreases in HAl values which occur within this range are offset Dy gains in total wetted surface area, resulting in relatively stable rearing habitat potential at higher flows. 3.4 Representative Group IV Aaseruae et al. (1985) delineates the 23 specific areas within this group on the basis of their low breaching discharges and intermediate to high mean reach velocities. The side channels which c omprise these specific areas possess lower mean reach velocities than adjacent mainstem channels. Substrates range primarily from cobble to boulder. Four modeling sites represent Group IV: 112.6L, 131.7L, 134.9R and 136.0 L. Of these, Site 112.6L is the largest ana Site 136.0L the smallest of the sites ir.vestigated. In spite of their disparity in size the modeling sites are characterizea by similar surface area and habitat index response curves. Compare the aerial photographs of the modeling sites presented in Plates A-15 through A-22 (Appendix A) with the wetted surface curves ~n Figures 36 through 39. As is typical of most side channels of the middle river, wettea surface area responds to changes in streamflow more rapidly 77 Figure 36. -......... ...... c: Ql u t..

This response pattern is accentuated at sites with wide, shallow channel cross sections such as Site 131.7L (Plates A-17 and A-18, Figure 37). In terms of juvenile chinook habitat potential, the most remarkable feature of Group IV modeling sites is the comparatively large amounts of WUA they provide at low to moderate mainstem flows. A comparison of the WUA values and, more appropriately, HAl functions (Figures 40 through 43 ) with esti- mates obtained for modeling sites from other Representative Groups suggests that Group IV specific areas provide a significant amount of rearing habi- tat within the middle river. This conclusion is supported by ADF&G sampling data indicating high utilization of these sites by juvenile chinook during the summer months (Dugan et al. 1984).

Turbidity levels are high at all aischa:-ges ana most areas of the sites possess suitable depths for rearing fish. Changes in WUA ana HAl are therefore airectly proportional to the increase or aecrease in the availability of suitable velocities. As an example, Williams (1985) aemonstratea that the total area within Site 11 2 .6L possessing suitable rearing velocities is five times greater at 13,500 cfs than at 33,000 cfs . 8 2 C> C> ..... >< <{ (f') 31: (X) .......... w <{ :::l 31: ....... <{ .T.

However, mean reach velocities measured at specific areas within this group averaged 3.3 fps at 10,000 cfs (Aaserude et al. 1985), well above the range of velocities tolerated by juvenile chinook salmon, suggesting that for the group as a wl'ole, the amount and proportion uf gross rearing habitat is probably greatest when flows are less than 10,000 cfs. Regardless of discharge levels, the quality and quantity of usable rearing habitat is greatest along the margins of the modeling sites due to the reduction of velccities in these areas. The specific areas relegated to Representative Group IV have been divided among the four study sites on the basis of th~ir structural habitat indices. Over half of the specific areas are grouped with Site 131.7L due to their poor structural habitat quality. Sites 136.0L and 134.9R were assignea 6 and 3 of the specific areas, respectively. The remaining 3 sites, all possessing SHl values of 0.59 or greater, were grouped with Site 112.6L. HAl response functions were derived for each specific area by normalizing the parent modeling site curves using breaching flow dif- ferences and SHI ratios. The derived HAl curves are shown in Figures 40 and 43. The strong resemblance between curves is related to their low breaching discharges and simi 1 ar hydraulic geometry. The speci fie areas associated with Site 131.7L deviate slightly from the other sites in that rearing habitat availability peaks in the vicinity of 8,000 cfs rather than at streamflows of 5,000 cfs or less. 87 The aggregate WSA response for the group is shown in Figure 44. As discussed above, the proportion of the wetted surface area provid i ng usable chinook habitat in Group IV sites, particularly in the lower flow range, is high in comparison to specific areas from other representative groups. This characteristic, when coupled with the fairly large surface areas associated with Group IV specific areas, results in exceptionally large rearing WUA forecasts for Representative Group IV as a whole (Figure 44). The significance of this fact will be discussed in Section 4.0 following presentation of aggregate WUA curves for all representative groups. Juvenile chinook potential in Group IV sites is highest at mainstem aischarges of 10,000 cfs and less. Peak rearing WUA values (approximately 4.1 million square feet) are attained at 8 -8,500 cfs. This trend is related to the low breaching flows characteristic of specific areas within this group . The composite suitability of velocity and depth within these sites decreases rapidly as flows increase; WUA declines concomitantly, reaching a low of 1.6 million square feet at 35,000 cfs . 3.5 Representative Group V Thi s group includes shoal areas which transform into clear water s id e sloughs at lower mainstem d ischarges. A shoal is si milar to a riff l e in that both are topographic high points in the longitudinal Ded profi l e of the river ana are therefore zones of accretion.

Due to reduced flow in these areas, shoals are characterized by fine sediments (sand and gravelsi aeposited on the falling stages of floods and at low flow. Larger substrates are possible if the shoal has stabi 1 i zea and begun to take on gravel bar characteristics. Shoals naturally evolve into gravel bars or islands as erosion continues on the opposite (outer) bank. Flow across shoal areas may be transverse to mainstem flow and velocities tend to be slower-than-average due to the drag effect exerted by the streambed. As water levels drop, flow is concentrated in a few small channels which feed a larger single channel on the inside of the shoal. When feeder channels dewater at lower discharges there is usually suffi- cient mainstem downwelling through the head and sides of the channel berm to maintain a small amount of clear water slough habitat at the site. The general morphologic features described above may De observed in aerial photographs (Plate A-23) of Site 141.6R--the only modeling site found in Representative Group V. Site 141.6R begins to convey mainstem water at 18,000 cfs but is not controlled by mai nstem discharge unti 1 22,000 cfs. Site flows under non-breached conditions average 5 cfs. Wetted surface: area and juvenile chinook weighted usable area at S~te 14.!..6R are assumed to remain constant in the non-breached state; the ratio of WUA to WSA, expressed as a percentage, is 13.4 percent (Figure 45).

Other than turbidity, the most significant factor contributing to the sharp rise in usable habitat is the large increase i n wetted surface area. Most of the recruited habitat is shallow ana slow velocity areas that may be usea to some extent by young chinook. Figure 45 indicates that over 90 percent of the total surface area has at least some rearing habitat value at discharges between 23,000 ana 32,000 cfs. Maximum WUA, HAl, ana HQl values occur at the lower end Of this flow range; each of these habitat indices peak in the range of 24,000 ana 25,500 cfs. Habitat 1 ndex curves are drawn out at their upper enas by the graaual loss of suitable velocity areas. Eventually, flow over the shoals is fast enough to significantly reduce the availability ana quality of chinook rearing habitat at the site. There are 9 specific areas within Representative Group V. The areas breach over a wiae range of mainstem discharges (<5,000 to 23,000 cfsl ana exhibit large variations in structural habitat quality. The HAl function obtained for Site 141.6R, which breaches at 22,000 cfs ana has a comparatively high SHI value, was usea as a template for deriving HAl curves for all specific areas within the group (Figure 46 ana Appendix B). There does not appear to be any carrel ati on between the magnitude of breaching flow and structural habitat quality of peak habitat availability for these specific areas. Collectively, the specific areas which make up Representative Group V do not provide significant amounts of juvenile chinook habi ·':at. even under ideal flow conditions. The low aggregate WUA values portrayed in Figure 47 result from 1) the small number of specific areas assigned to Group V. ard 2) the small amount of total wetted surface area associated 92 C> C> >< <{ U1 31: -.......

Overall, less than 0.4 million square feet of rearing WUA is provided by Representative Group V by streamflows within the range of 5,000 to 35,000 cfs. WUA values peak at approximately 26,000 cfs when joint surface area and HAI values are maximized (Figure 47). 3.6 Representative Group VI The specific areas within this group are products of the channel oraiding processes active in the high gradient middle segment of the Susitna River. Included are overflow channels which parallel the adjacent mainstem. Typi- cally separated from the mainstem by a sparsely vegetated bar, these channels may or may not possess upwelling. These specific areas may repre- sent more advanced stages of shoal development in which their gravel bars have stabilized due to the growth of vegetation and further high-stage sedimentation, and mainstem overflow is usually delivered by a single dominant feeder channel. Incision of the lateral channels has gradually occurred over time, leading to lower head berm elevations and coarser substrates. Side channel gradients are usually greater than adjacent mainstem channels as a result of hydraulic processes which adjust channel morphology to maintain transport continuity. The spectrum of shoal-to-side channel developmental stages represented by the specific areas of Group VI is indicated by the wide range of breaching discharges ana structural habitat indices recorded by Aaserude et al. (1985). Included in Representative Group VI are modeling sites 133.8L and 136.3R, which breach at 17,500 and 13,000 cfs, respectively, but remain watered at non-Dreacheo mains tern discharges. P 1 a tes A-24 through A-26 (Appendix A) give some idea of the morphologic features and wetted surface area response 95 to flow of Group VI modeling sites. A large backwater occurs at their con- fluence with the mainstem channel. The gravel bar at Site 136.3R appears to be more stable than the bar at Site 133.8L, judging from differences in the type ar.d amount of vegetation cover. Both modeling sites are rela- tively flat in cross section except for deep narrow channels running along banks opposite the gravel bars. These banks are steep-walled whereas banks formed by the gravel bars are gently sloping. These features are largely responsible for the type of response of juve~ile chinook habitat to changes in mainstem discharge observed at the two Group VI modeling sites. Habitat index and surface area response funct·;ons derivea for Site 133.8L and 136.3R are conspicuously similar, particularly if allowance is made for differences in mean channel width (Figures 48 and 49). In both cases, the anticipated increase in WUA following breaching occurs, but after attaining moderate levels the amount of rearing habitat remains fairly constant at higher mainstem discharges. This pattern, which is uncharacteristic of more developed side channels (compare, for example, the WUA response curves for sites from Representative Group VI with results for Group III and IV modeling sites), is also apparent in the relationship between gross habitat area and river discharge. The constancy of WUA and GHA values at moderate- to-high mainstem flows results in generally stable haDitat quality at the sites, implying that areas suitaDle for chinook rearing are recruited and lost at comparable rates. Regardless of flow levels, most juvenile chinook habitat at Sites 133.8L and 136.3R is associated with the gravel bar shoreline and backwater area of both sites. 96 -..., -......... .., -0'" ~ ftJ cu c.. < .., c cu u c.. cu a..

HAl functions developed for the two modeling sites exhibit the expected rise and fall in juvenile chinook habitat availability which attends breaching and further increases in discharge. However, because WUA values remain constant at higher flows, the slope of the descending 1 imb of the HAl curves is not as great as observed for other representative groups. Basea on an assessment of structural habitat data obtainea at modeled and non-modeled specific areas in Group VI, exactly half of the 14 specific areas may be grouped with Site 133.8L and Site 136.3R, respectively. HAl functions derived from the modeling sites are presented for each subgroup in Figures 50 and 51 and Appendix B. Note the relatively narrow range of breaching flows and high SHI va~ues (see also Table 4) of specific areas associated with Site 136.3R as compared with areas represented by Site 133.8L. Due to their relatively high breaching flows and rapid wetted surface area response following breaching (Figure 52), specific areas within Representative Group VI provide considerably more juveni ~~ chinook WUA at high as compared to low mainstem discharges. Figure 52 indicates the aggregate rearing WUA function derived as the sum of individual specific area habitat values for flows ranging from 5,000 to 35,000 cfs. Rearing habitat potential increases steadily as a function of flow throughout this range. The amount of juvenile chinook WUA forecast for 35,000 cfs (1.3 mi 11 ion square feet) represents over 30 times the amount of WUA forecast for 5,000 cfs (0.04 mi 11 ion square feet). The correlation between wetted surface area and aggregate rearing WUA values is more pronounced in Group VI than in other representative groups due to the relative constancy of HAl values across all flows. 99 25 .00 22 .50 20 .00 0 0 17 .50 ..... >< 15 .00 <( (f) X 12 .50 ..... -0 <( ::J 0 X 10 .00 t-1 <( :r 5 .00 2 .50 0.00 0 F1~ure 50. ~000 --T 8000 REPRESENTATIVE GROUP VI ,--r-----r--·-- 12000 16000 20000 24000 MAINSTEM DISCHARG E (CFS) 28000 -, 32000 133 .8L n = 7 36000 Response of chinook rearing hai>Hat availa1>1lity to mctinstem ~ischctrge within non-mo~ele~ specific areas of the m1~~1e Sus1tna River which ctre associate~ with mo~eling site 133.8L of Representative Group VI. ,_. 0 ,_. 0 0 ...... >< 4 (/) :X ...__ <( :::l :X 1 --i <( :c 35 .50 31 .00 - 29 .50 - 26 .00 - 22 .50 19 .00 15.50 - 12 .(1•J - 8 .50 5 .00 ---1- 0 ~000 Figure 51 .

In most case~. the specific areas are comparatively short with small length:width ratios and are composed of a single riffle extending from the head of the site down to a large backwater area at the mouth. The transition from riffle to backwater pool is defined by an abrupt step in bed and water surface profile. Head berms are generally broaa-crestea and the riffles of greater-than-average slope. The increase in water velocities resulting from steep riffle gradients and an increase in streamflow tenas to counter- act the staging effect of rising mainstem flows at the mouth of the site. Consequently, the rate of change in backwater area is less than is observea at lower gradient sloughs and side channels over a comparable range of discharges. Backwater area varies at Group VII sites primarily by expanding or contracting laterally as flows chang~ Flow characteristics within backwater pools incluae near zero velocities and a calm surface, as compared to the broken ana rapidly moving water of riffles. Consiaerable longitudinal variation in streambed texture occurs in Group VII specific areas. Riffles are composed of rubble ana boulder size substrates, whereas backwater areas tend to have sandy beds. Perioaic high flows may temporarily expose coarse sediment in backwater pools which is subsequently covered by sana and silt during periods of low flow. High turbidities also prevail at these sites since upwelling is not present. 103 Modeling Site 119.2R is the sole representative of the 7 specific areas classifiea within Group VII. This site possesses the typical riffle/pool sequence characteristics just described (Plates A-27 and A-28 in Appendix A). As indicted in Figure 53, a basal level of wettea surface area ana juvenile chinook WUA is maintained under non-breached conditions by backwater effects. Peak rearing habitat potential occurs shortly after the berm at the head of the site is overtopped ana the riffle area is inundated. The relatively broad width ana uniform elevation of the head berm strongly influences the distribution ana amount of juvenile chinook habitat at Site 119.2R. Areas of usable habitat within the riffle rapidly expand until local velocities begin to exceed tolerable limits which in turn prompts a aecline in rearing habitat. Maximum WUA values are forecast for discharges of 12,500 to 13,000 cfs, when juvenile chinook WUA is nearly four times greater than WUA present unaer non-breached conditions (39,300 versus 10,500 sq.ft./ft.). Gross habitat is widely distributed throughout Site 119.2R at flows ranging up to 17,000 cfs, as demonstrated by the GHA response to discharge in Figure 53. However, habitat Hailability and quality, as indexed by HAI and HQI values, begins to dimin ish appreciably around 12,000 cfs. Peak HAI ana HQI estimates were sim i lar at 40 percent, a fairly high value in comparison to other modeling sites. The minimum HAI value was 3 percent at 35,000 cfs. This HAI value was estimated by extending the WSA ana WUA curves by eye for discharges exceeding 20,000 cfs (Hilliard et al. 1985). The HQI curve was not extrapolated past 20,000 cfs, but HQI values may be expected to be higher than HAl values to a aegree which is proportional to the difference between gross habitat area and wetted surface areas at high discharges. 104 -... -........ ... -C" ~ ttl cu ~ < ... c cu u ~ cu a..

HAl functions derived from modeling results for Site 119.2R display the low breaching flows and comparatively large habitat potential at low discharges associated with specific areas of Representative Group VII (Figure 54 and Appendix B). Within a narrow range of low mainstem discharges (10,000 to 13,000 cfs), HAl values compare favorably with peak HAl values recorded for specific areas from other groups. The marked decline in habitat avail- ability at higher flows and the overall poor structural habitat quality (i.e., low SHI values) of Group VII sites suggests that hydraulic geometry plays a more important role than does object cover in determining the collective rearing habitat potential of this group. As was the case for side channels comprising Representative Group IV, which are characterized Dy similarly low breaching discharges, the seven specific areas of Group VII provide notably greater amounts of usable rearing habitat at low than at high mainstem flows, as evidenced Dy the aggregate WUA function in Figure 55. This results from the comparatively high HAl values which occur immediately subsequent to breaching and their rapid decline at higher flows. Juvenile chinook WUA peaks at 0.3 million square feet at 8,000 cfs, remains at this level through 13,000 cfs and declines to 0.08 million square feet at 35,000 cfs. 3.8 Representative Group VIII This group is comprised of 22 specific areas which tend to dewater at intermediate to high mainstem discharges. The absence of an upwelling groundwater supply may De due to the local structural geology and the location of the channels relative to sources of subsurface flow. Aaserude et al.

Apparently groundwater flow is either diverted away from these sites or occurs at a lower elevation than the bed elevation of the exposed channels. In spite of their tendency to aewater, specific areas in Group VIII are similar to specific areas assigned to Groups II and III in their hydrologic, hydraulic, and morphologic properties. Therefore, because Group VIII does not possess a specific area with a rearing habitat modeling site, HAl functions based on modeling sites from Representative Groups II and III were used to represent Group VIII in the habitat extrapolation process. An obvious requirement was that the habitat function~ for modeling sites selected to represent this group De modified to reflect the total loss of rearing habitat as mainstem stage declines below head berm elevations. Candidate modeling sites include Site 144.4L from Group II and Site 132.6L from Group 111. The first modeling site is recommended by its high breaching discharge, its morphological similitude with several Group VIII speci~ic areas, and by the general shape of its habitat response curves. Figure 29 illustrates the WSA, WUA and HAl curves which have been aerived from Site 144.4L to represent a subclass of Group VIII specific areas. Note that the lefthand limb of the curves have been truncated at a breaching flow of 21,000 cfs. Site 132.6L has been selected to represent the subclass of specific areas from Group VI II which dewater at intermediate discharges. Basea on an examination of aerial photography obtained at several mainstem flows, these specific areas and Site 132.6L possess similar longitudinal a~d cross sectional profiles. Site 132.6L, which breaches at 10,500 cfs, eventually 109 aewaters at 6,000 cfs as the water surface elevation drops below the eleva- tion of the groundwater table. However, the revised modeling site habitat response curves have been truncated at 10,500 cfs to accurately reflect the rapid dewatering which occurs at Group VIII specific areas. HAl curves derived from the modified HAl functions of S i tes 144.4L ana 132.6L a1·e presented in Figures 56 ana 57 ana aggregate WSA response in Figure 58. The spc_ific areas from Group VIII were divided between the modeling sites on the basis of breaching flo~; the 9 specific areas which breach at 15,500 cfs ana less are associated with Site 132.6L, and the remaining ll sites are represented by Site 144.4L. Since all of the specific areas associated with Group VIII are dewatered by 8,000 cfs, juvenile chinook habitat does not exist at flows below this value. This is reflected in the aggregate rearing WUA curve developed for Group VIII (Figure 58). WUA accumulates rapidly as the specific areas become !>reached and peak values (0.7 million square feet) are attained at 29,500 ~fs. Rearing habitat potential declines slightly at higher flows. 3.9 Representative Group IX This group contains specific areas categorized as m~i ;•stem, side channel, or shoal hal>itat with mean reach velocities ~reater than 5 fps at 10,000 cfs. These sites are closely associated 'llith the main river cor- ridor, usually convey a s ignificant percentage of the total discharge, ana possess small length to width ratios.

Curved channels are characterized oy a transverse Ded slope, with the thalweg located near tne outside of the bend. In general, the inside banks of Group IX specific areas are formed oy mildly sloped and vegetated gravel bars. Two habitat modeling sites were selected from the specific areas included in Group IX. Sites 101.5L and 147.1L are large channels classified as mainstem habitat over the entire 5,100 to 23,000 cfs flow range (Plates A- 29 through A-32 in Appendix A). Due to an excess of areas with velocities greater than 2.5 fps (i.e., the upper velocity threshold for rearing), the modeling sites provide little juvenile chinook habitat in relation to the total volume of water they convey. This conclusion is strengthened Dy the large differences observed between WSA and GHA estimates and the low rearing WUA values forecast for all mainstem discharges (Figures 59 and 60). Wetted surface areas change at comparatively slow rates as discharge varies at both sites due to their large size and a tendency to compensate for varying flow more through adjustments in water depth and velocity than in top width. Both GHA and WUA increase slightly at higher mainstem discharges~ thus, the availability of usable rearing habitat and its distribution within the modeling sites tends to remain constant throughout the range of evaluation flows. In a detailed analysis of cross section velocity profiles at Sites 101.5L and 147.1L, Williams (1985) noted that suitable rearing areas are confined to nearshore zones in the channels, primarily along the gently sloped island Danks, due to high mid-channel velocities. The ratio of juvenile chinook WUA to wetted surface area at these sites is very low, on 114 Figure 59.

These values are considerably lower than HAl estimates obtained for modeling sites from other representative groups. The ratio of WUA to GHA is predictably higher, ranging up to 22 percent, but also slightly lower than HQI ratios calculated for other sites. Taking these indices into account, the juvenile chinook habitat potential within Group IX specific areas is judged to be inferior in quality. Using the HAl functions developed for Sites 101.5L and 147.1L as templates, HAl curves were derived for specific areas within Group IX. Adjustments were made to account for differences in breaching flow and structural habitat quality. In regard to structural habitat, the mean SHI value for specific areas in this group is high compared to other representative groups. Tnis results from the large substrate sizes which predominate in the high velocity channels ana the high cover value assigned to them in the SHI calculations. Nine of the 20 specific areas within Group IX have been grouped with Site 101.5L; the remaining 11 sites are represented by site 147.1L. HAl functions derived for moaeled ana non-modeled specific areas are presented in Figures 61 and 62 and the aggregate WSA response curve for Group IX in Figure 63. The collective rearing habitat potential of the 20 specific areas in Group IX increases from 0.3 million square feet at 5,000 cfs to a peak of 0.6 million square feet at 27,500 cfs {Figure 63). Aggregate WUA values increase steadily over this flow range although the rate of change is very low in comparison to other representative groups, with the exception of Group I {uplana sloughs), being only slightly greater than the rate of change in wet tea surface area. J uveni 1 e chi nook WUA remains constant at 117 higher flows as increases in wetted surface area are offset by gradual reductions in rearing habitat availability. 118 1 00 6 40 580 - C> C> 5 20 >< 4 60 <l (f) "31:: 4.00 ........ <l :::> "31:: 3 .40 >--< <f :r: 2 20 1.60 I 00 0 Figure 61. -I 4000 REPRESENTATIV E GROUP IX -I 12000 --·r 16000 -· I . -.-.. ~--- 24000 28000 MAINS f f:M 0 ISCitARG E ICFS) 32000 S I T f: t 0 1. ~L n , 7 lbOOO Response of ch1nook rearing habitat ava1lab1lity to ma1nstem aischarye w1th1n non-modeled spec1fic areas of the middle Susitna River which are associated with mode11ng site 101.5L of Representative Group IX. 40000 4. 70 4 .40 - 0 0 4 10 X 3 .80 ~.t tn 3: 3 .50 -, 4 'V :=! :::> 3: 3 .20 ·- ...... 2 .90 4 .I 2 .60 2 .30 2 00 0 4000 Figure 62.

Underpinning the extrapolation methodology are several assumptions related to physical habitat modeling and river stratification procedures. The primary assumption of the haoi tat modeling studies is that weighted usable area (WUA) is an index of physical habitat conditions and changes in WUA are attended by adjustments in the distribution and relative abundance of juvenile chinook populations. Although other physical and non-physical components of fish habitat not included in the calculation of WUA may influence the sutvival and growth of juvenile chinook salmon, the physical environment affects to a substantial degree biotic processes of the aquatic community. Moreover, considerable data exist which indicate the importance of individual microhabitat variables for influencing the distribution of juvenile chinook within different subenvironments of the middle Susitna River. Hence, physical habitat modeling is an a~propriate method for assessing the influence of project-induced changes in streamflow on juvenile chinook habitat. It is recognized that numerous environmental variables influence the availability of chinook rearing habitat and that these variables are typi- cally not independent of one another. Under some circumstances, however, the availability or quality of juvenile chinook habitat may be governed primarily oy one or two variables whose influence is more pronounced than 122 the combined effect of all other environmental variables. An example is the positive ~orrelation <luring the summer growing per1o<l between juvenile chinook distribution ana turbid water. This may reflect the value of turbidity as cover for juvenile chinook as reported by Dugan et al. (1984) or it may reflect a greater abundance of drifting invertebrate prey in the turbid mainstem ana siae channel nabitats than in clear water sloughs. Water clarity was treated as a cover variable in the physical habitat moaeling studies since our present understanding of turbidity, fooa avail- ability, ana juvenile chinook distribution aoes not warrant an evaluation of the relationship of turbidity to fooa supply. Nevertheless, if it is drifting invertebrate prey associated with turbid mainstem ana side channel flow which juvenile chinook are responding to rather than the cover value of turbidity, the physical habitat moael remains valid. For it is the influence of turbidity on juvenile chinook distribution, nnt the cause, which is being moaelea. The influence of water clarity was incorporated into the modeling process through the application of separate clear ana turbid water habitat suit- ability criteria for juvenile chinook. Clear water velocity ana cover suitability criteria were used to calculate rearing WUA indices for modeling sites unaer non-breached conditions. Following breaching high turbidities prevailed at the moaeling sites ana turbid water criteria were appliea. The results of the rearing habitat modeling studies conauctea at individual modeling sites indicate surface area ana rearing habitat response curves are generally more similar within representative groups (where two or more 123 modeling sites occur) than between groups. The amount of rearing habitat available at a particular site is strongly affected by the mainstem dis- charge at which its upstream berm is overtopped. Under non-breached condi- tions, juvenile chinook habitat is typically relatively small. The combi- nation of the influx of turbid water to the channel and the increase in its wetted surface area which accompany breaching typically increases the availability of rearing habitat significantly. Positive gains of WUA continue, but at a gradually declining rate, as mainstem discharge increases and water velocities at the site remain favorable. Juvenile Chinook habitat.tenas to decrease more rapidly in smaller channels as mainstem discharge increases than in larger channels due to a more gradual response of near shore velocities to changes in flow in large channels. Thus, relatively small changes in the availability of rearing habitat occur as flows increase or decrease in the large side channels ana mainstem. It should be emphasized, however, that these large side channels and tOe mainstem contribute a disproportionately small amount of habitat in relation to their wetted surface area. Based on the delineation of specific areas ana their classification into the representative groups reported by Aaserude et al. 1985, we have developed aggregate rearing habitat response functions for the majority of the subenvironments which directly respond to changes in mainstem dis- charge. These are summarized in Figure 64. We have not combined WUA values for the representative groups to obtain an aggregate WUA value for the entire middle Susitna River. Evidence of variability in juvenile chinook abundance and distribution between representative groups is provided by 124 30 .00 27 .00 z~.oo Zt.OO ...... a rn 11.00 0 rn 15 .00 c 0 12 .00 e < 9 .00 U1 :E e.oo 3 .00 0 .00 5 .00 ~.50 ~.00 3 .50 ...... a rn 3 .00 0 rn Z. 50 c 0 2 . 00 e < 1.50 :=l :J:: I. 00 . 50 0 .00 Figure 64. 0 ....- /./""' ...--· REPRESE NT ATIV E GRO UP S I -IX -· -------· ___..--· ___ .--. .---·--·--· -· / / -......... ......... ----- / ---;;: 2+t / ---------------/ :;::...--· :;..---- / :---· ----......... :;....---L - ---· 7+5 ---___., - - -~ -=--=--------------------------=----:::=-=-=----~--=---==-- - 1000 ./ / /'.. \ \ \""""'- 16000 \ " ........... ........... 211000 --~ ........... ----2 6 ---·~:::::::::::--·-·-9 -/ ........... - 1000 !2000 16000 20000 uooo 2!1000 32000 36000 MAI NSTEM DISCHARGE [c f s l Comparison of the aggregate response of c hinook r e aring habitat potential [WUA] for Representative Groups I through IX. 125 Hoffman (1985), suggesting that WUA indices for different representative groups be adjusted for utilization prior to being aggregated. Other considerations which should be addressed prior to drawing final conclusions from the habitat response functions provided in this report are the influences of food availability and water temperature on tne quality of rearing habitats. In addition such seasonal aspects as availability of chinook overwintering habitat should be considered. The habitat modeling results presented in this report are not directly applicable to evaluations of winter habitat since hydraulic characteristics and fish behavior are different at this time of year. In regard to the open water period, however, time series and habitat duration analyses at the representative group level are recommended for comparisons between groups and flow regimes. Whereas the primary utility of the WUA response functions is their application to existing habitat conditions, the general shape of the WUA response functions are also well-suited to assessing with-project effects on juvenile chinook habitat. 126 LITERATURE CITED Aaserude, R.G., J.
