Lake Bathymetry GIS Data

This interactive map allows users to search, view, and download our lake bathymetry data. We captured these data from historic hydrographic survey maps, digitized the information, and then digitally modelled the data to produce a continuous surface for each lakebed. Three files make up each dataset for 169 Alberta lakes: a shoreline contours shapefile, a bathymetry contours shapefile, and an ASCII grid of the lakebed. This interactive application shows each lake's shape and depths using the shoreline and bathymetry contour shapefiles. Contour units are metres above sea level (m asl).

The app is currently down and is under construction.
