A mot-e deta ll ed descr· i pt ion of each aquat l c habitat type has been pre- parea by the Alaska Department of Fish and Game ( 1983). MlL~tem habitats are those channels of the r·iver characterized by turbid glacial ilow that convey more than 10 percent (approximare) of the total flow at a given site. Side .charmel habiJrats are those channels of the river char·acterized by turb d glacia flow that convey less than 10 percent <approximate) of the total flow. habitats contain clear water. local surface water runoff and upwel 1 ing are the primary water sources that supply clear water to these hab tats. Side sloughs have nonvegetated upper thalwegs that are overtopped dur ng periods of moderate to high marnstem dlscharga Once overtopped, side sloughs are cons dered slde channels. are clear water habitats that depend upon upwell !ng and/or Joci'll runoff for their wat·er sources.

He! i coptet-reconnaissance f I i ght.s were conducted over the Talkeetna-to- Devl Canyon reach at the same mainstem discharges at which the aerial photography was obtai ned. Our I ng each of these reconnaissance f I i ghts, aquatic habitat types were Identified using the key presented as Figure 1, and their locations were mapped on 1 inch::::1~000 feet bluel ine prints of the Susitna River. Dewatered gravel bars and streambank areas were sketched on the b I u•31 inc prints as were boundaries of the various aquatic habitat types. Photographic mosaics were prepared from the overlapping black-and-white photos to prov! de contInuous 1 i nch::::1 ,000 feet coverage of the Taikeetna-to-Devll Canyon river segment for each of the four discharges. The photo mosaics were subdivided into eighteen sections of approximately the same length~ with a small amount of overlap between adjoining r-iver sections. The same dividing llnes between adjoining segments were maintained for ail four discharges, and a se~ of eighteen 4-1/2 Inch by 15 inch photo plates were printed from the sectioned mosaics for each of the four-d f scharges <Appendix 1 ). Each photo pI ate was car&ful ly examined and areas that were too smal I In size to provide detailed resolution wer·e enlarged to a scale of i lnch=250 feet. 4 Aqua t i c h a b i tat boundar i e 5 fT1 a p p '2 d on the b ! u e I r: e p r f n t 5 au r i helicopter reconna ssance lights were transferred to individ 1 photo plates and enlargements {Figure 2). t•latch! lnes were dra'xn on adjoining pI ates to ensure that habitat areas wou I d not be c:Juntecl tw ce thin over apping sections near the edges of phcto plates. The boundar of each enlargement area was estab ished using identifiable features n the photography and drawn on both the plate and the indlv dual enlargement to ensure that areas within the en I argement cou I d be summed and compared with the enlargement area on the plate. The external boundaries of the total area to be included In the surface area analysis (hereafter referred to as the corridor area) were defined on each pI ate, so that sub-areas within the corridor could be tota I ed and compared wi+h the total corridor area by plate. The corrfdor boundaries were established using physical features identifiable on a! four sets of photos. In many cases, lt was necessary to gc beyond the river c~anne! boundaries to establIsh an ldentlfiab e corridor boundary. That area located between the corr·fdor boundary and the e:channel boundary was termed background (refer to Figure 2b). As the second index of quality control, the total digitized corridor area with n the Tal keetna-to-Dev i I Canyon river segment was compared among the four sets of photography. F!GU~E 2~.

Individual habitat areas, excluding those within a designated enlargement, were assigned a unique sequential number and their surface areas digitized. Replicate measurements were made of Individual areas to ensure repeatabll lty within 5 percent.

In this wayp the influence of mainstem discharge on the surface area of spec tic habitat types or I ons could be investigated" Correct on factors were entered to standardize measurements to a common scale of 1 inch=1 ,000 feet. Surface areas 1·1 thin enlargement ar·eas 1r1ere divided by a factor of 16 to account tor the four-fold d tference In scale between 1 nch=2.50 feet and 1 inch=l ,000 feet.

Tt1eref ore, all surface area measurements for the 9,000 cts photography were multipl led by a factor of 0.85 to corr·ect for the difference in scale. Totai surface areas were calculated for the entire control corridor between Talkeetna and Devil Canyon by aquatic habitat type for each of i-he tour discharges. Summations of surface area for the corridor and aquatic habitat types were also made by incJividual plate (Appendix 2). Percentages of the total surface area represented by each aquatic habitat type were calculated for each of the four discharges by river reach and lndlv idual plate. A series of procedures were employed to evaluate the rei iabll ity of the digitizing. These procedures identified flow-dependent trends In the digitized data that would verify the accuracy and consistency of the methode og~ Comparisons were made between total surface areas digitized at each of the four discharges for the corridor, vegetated bar, back- grounds and tributary areas. In addition, percentages of the total surface area represented by each aquatic habitat type were calculated as were the percentages of total surface area for exposed gravel, vegetated bars and background area at each of the four discharges. These per- centages wbre summed and the deviation from 100 percent was determined. Average monthly discharges for the Susltna River at Gold Creek range from 1,500 cts/day In winter to 28,000 cfs/day during summer, with the average annual discharge being 9,700 cfs/day (Figure 3a).

Total surface areas of each hab tat type within these segments were deter-mined to focus attention on the diversity of habitat types and surface area responses among the four river segments.

AI though each set of photographs obtaI ned In this study \'Jere genera! ly clear and comple't-e, the time of day 6 datf;, and pre- vail ing weather conditions at the time the aerial photographic missions were flown affected the extent to which detailed riverine features were visible. The 9,000 cfs photographs, obtained on October 10, 1983, were taken after lee ~ad begun to form along the river and a I ight snowfall had covered the ground. in some cases, this made the determination of the water's edge more difficult. In other cases, particular!/ for up 1 and s i oughs, the sharp contrast between the dark open ~>Jater and the sno\11 covered shoreline combined with a lack of deciduous foliation greatly assisted visual determination of the slough boundary. 12 Talkeetna to La.-.~ Creek (RM 101 to 113) Lane Creek to Curry (RII!i 113 to 122) Curry lo Gold Creek (RM 122 !o 138) Gold Creek to De>vl!

This resulted in few sr~aaows, r.h!cr1 enabled excellent delineation of water's edge and slough bouncaries. The 12,500 and 16,000 cfs photographs were obtained on September· 11, 983, and September 6, 1983, respectively. At this time of year the sun ls at a low angle, and deciduous foliation is we! I developed, resulting in extenslve shadows along the south and east shore! ines. These shadows somet i rnes obscured the water's edge and made some surface area de If nea- t ions d fficult. In spite of the minor differences In photographic detail, the accuracy and reliability of areal measurements obtained by the digitizing technfque appear to be good. A comparison between total surface areas for the centro i corridor at each of the four discharges devIated from 1.1 to 5.3 percent of their arithmetic mean. This suggests that a high level of precision and good repl icabil ity were maintained during the digitizing of all four sets of aerial pnotgraphy. Total sJr'face areas for vegetated bars and back ground areas were com pared among the four discharges and were found to remain relatively constan~ This would be expected due to the I lmlted Influence of the flow fluctuations on these areas. Surface area responses are a function of streamflow and channel geometry. It channel geometry remains constant over t l me., the surface area responses can also be expected to remain constant.
