Crean Lake Hydro-acoustics Project 2004—Prince Albert National Park

The Lake Trout assessment project in Crean Lake, Prince Albert National Park, is a collaborative project with partners including Prince Albert National Park, Saskatchewan Environment Hydro-acoustics program, Saskatchewan Research Council, Prince Albert Model Forest, and Crean Lake Trout Working Group.

The lake depth data was collected and manipulated into a digital elevation model for Crean Lake. The fisheries data was captured and converted from sound echoes into a three-dimensional spatial representation in x,y,z coordinates by fish class. Analysis of this data was performed to ascertain fish stock numbers, habitat preferences related to temperature, and dissolved oxygen and food sources. The map displays the results of data collection, capture, and conversion. The dissolved oxygen and temperature average surfaces are based on the vertical averaging of inverse distance weighting statistics for the -1, -5, -10, -15, and -20-meter depth values obtained from the water quality profiles.

A more detailed map was published in Esri Canada’s Map Gallery Calendar for 2006.
