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.

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.

pI ates to ensure that habitat areas wou I d not be c:Juntecl tw ce thin

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.

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). Sno~>~melt

::-r·om an cP1cdysls of hydrologic datap !t was determined i·hat the aeri
photography obta ned at a mainstem discharge of 23,000 cfs represents a
typical m d-summer discharge for the Talkeetna-to-Devil Canyon r-each of
the Susitna River. Therefore, this photographv was used to dep ct
base ine mid-summer habita·r surface areas~ and the percent change in
surface areas as a function of rnalnstem dischar·ge was r·eferenced ·ro the
digitized surface areas on the 23,000 cfs photograph~
Because the change in surface area of aquatic habitat is a funct on of
discharge and channe I geometry: the Ta I keetna-to=Dev I I Canyon reach was
subdiv !ded into four segments, each possessing somewhat di ferent
geomorphological char·acterlstics. 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.
RESULTS
Total surface areas within the :ontrol corridor are presented In Table 1
by aquatic habitat type and sub-area tor each mosaic. The areal
equivalent of the precision of measurement for eacn lndlvlduai digitized

Creek reach of the Susitna River (RM 113 to 138), in which a greater
percentage of the tote l surface area Is represented by gravel and vege-

channel pattern.
DISCUSSION
Air photo lnterpretatton is highly dependent on the qua! lty of the
photography. 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.

time of the year when the sun was at a high angle and deciouous veget~
tlon had not tully leafed-out. 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. Within the

A reduction of mainstem and side channel surface area and ~n Increase In
side slough and exposed gravel bar surface areas was ooserved at lower
discharges. This results from both the dewatering of areas ~~d the
change in their habitat class:fication. The increase in side slough
area results primarill from reclassification of slde channel habitat
and ami n m i zal-iun of backwater effects at the dO\'instream end of the
