AbstractThis report highlights the Cape Dorset watershed assessment activity conducted by scientists from the Canada Centre for Remote Sensing at Natural Resources Canada and staff from the Nunavut Research Institute (NRI) and the Community and Government Services (CGS) of Nunavut. This activity included the use of high resolution satellite imagery, airphotos, and onsite field surveys to map the watershed boundaries and lake depths of the fresh water supply lakes for Cape Dorset.
This activity was also used as a technology transfer exercise, whereby staff from NRI and CGS of Nunavut were trained to understand and use a set of tools and solutions for conducting small lake surveys and for collecting GPS locations.

Digital computer files resulting from this project, and described in this document, are available upon request by contacting the project leader or project members. The digital files comprise of:
- Vector files of the outlines of the watersheds for the primary lake (T-Lake) and a potential water source supply (Q-Lake) (ESRI shapefile.shp).
- Raster files illustrating the water depth model for the two lakes surveyed (Geotiff.tif)
- Vector files illustrating the depth contours (isobaths) for the two lakes surveyed (ESRI shapefile.shp).
- Tabular statistics featuring the water volume for the two lakes surveyed.
- Lake volume statistics stored as .kml files (Keyhole Markup Language) viewable on tools such as Google Earthtm.
- Vector files illustrating the depth contours for the two lakes surveyed stored as .img files compatible with Garmin GPS map devices.
- Precise GPS location of a reference point established during the field survey.
- Underwater video camera footage acquired at T-Lake (.avi/.asf)
