Cowichan Lake Bathymetry sample

Bathymetric Mapping of Cowichan Lake

In 2012 the Canadian Hydrographic Service (CHS - a division of the Science Branch of the Department of Fisheries and Oceans Canada) completed a bathymetric survey (underwater contour mapping) of Cowichan Lake for the Cowichan Watershed Board.

In 2014 the CVRD's GIS Department will utilize UBCM Gas Tax funding to merge that information with LiDAR and cadastre information to show foreshore and sub water surface contours for near shore areas around Cowichan Lake.
