The ADF&G Susitna Hydro Aquatic Studies program was initiated in November 1980. The five year study program was divided into three study sections: Adult Anadromous Fish Studies (AA), Resident and Juvenile Anadromous Studies (RJ), and Aquatic [ Habitat and Instream Flow Studies (AH). Reports prepared by the ADF&G prior to 1983 on this subject are available from the APA. [ The information in this report summarizes the findings of the 1983 open water field season investigations. Beginning with the 1983 reports, all reports were sequentially numbered as part of the Alaska Department of [ Fish and Game Susitna Hydro Aquatic Studies Report Series.

Part I, the "Hydrologic and Water Quality 6 Investigations", is a compilation of the physical and chemical data collected by th ADF&G Su Hydro Aquatic Studies team during 1983. These data are arranged by individual variables and geographic location for ease of access to user agencies. The combined data set represents the available physical habitat of the study area within the Cook Inlet to Oshetna River reach of the Susitna River. Part II, the "Adult Anadro [ mous Fish Habitat Investigations .. , describes the subset of available habitat compiled in Part 1 that. is utilized by adult anadromous fish studied in the middle and lower Susitna River (Cook Inlet to Devil [ Canyon) study area. The studies primarily emphasize the utilization of side slough and side channel habitats of the middle reach of the Susitna River for spawning (Figure A). It represents the first stage of development for an instream flow relationships analysis report which L will be prepared by E.W. Trihey and Associates.

Three infrared heat sensing devices (Hughes Probeye, Xedar Pyroscan, and [ AGA Thermovision) were tested to evaluate the feasibility of using infrared thermal imagery as a remote sensing technique for detecting and quantifying the amount of upwelling groundwater in slough habitats of [ the Susitna River. Results of these investigations indicate that the application of infrared heat sensing devices for locating upwelling is contingent on a host of environmental conditions and the level of detail desired. Areas of upwelling groundwater and their relative magnitude b were identified using these techniques; however, some areas known to have upwelling based on ground truthing surveys were not detected. This inconsistency is due to the wide variety of environmental conditions [ that occur within the Susitna River combined with the physical limitations of the technology. For these reasons, it is doubtful whether this technique can be applied on a large scale for the detection [ and quantification of upwelling areas.

L [ Upwelling groundwater is a principal variable influencing the suitability of slough habitats for spawning by chum salmon in the Talkeetna to Devil Canyon reach of the Susitna River system (ADF&G 1983; Chapter 7 of this report). Other investigators have also associated chum salmon spawning habitat with upwelling groundwater elsewhere in Alaska (Kogl 1965; Francisco 1977; Wilson et al. 1981). r L Preliminary evaluations of upwelling groundwater areas in the sloughs and side channels of the Susitna River to date have been conducted by L visual inspections of slough substrate (ADF&G 1983: Appendix C). [ Upwe 11 i ng groundwater was detected by observing the movement of sma 11 streambed particles as the groundwater was vented from the streambed. L Often times, the vented groundwater was expelled under pressure so that, in relatively shallow water, a disturbance was visible at the surface of b the substrate. Success of visual detection of upwelling groundwater in [ Susitna River sloughs, however, was found to vary with the particle size of the streambed substrate. Groundwater upwelling vents were easily [ discernible in silt and sand streambed substrates
