Open file (Geological Survey of Canada); 6750 A watershed outline map, a bathymetric map, and water related statistics of Geraldine Lake, the Iqaluit water supply reservoir where produced following fieldwork in Iqaluit during the summer of 2008. One objective of this initiative was to develop the technology for Nunavut scientists and to transfer the methodologies in communities where drinking water supply is at risk due to a declining supply and a changing climate. With support from Indian and Northern Affairs Canada (INAC), a small team of scientists from the Canada Centre for Remote Sensing (CCRS) are involved in a project to help characterize the water supply of Nunavut communities. This was a complex task involving the delineation of watersheds and estimation of the water volume of the supply lake for the community. To estimate this water volume, a bathymetric map was produced based on field surveys using a depth sounder equipped with a GPS. ...
