Five large lakes on the rocky Precambrian Shield of northern Saskatchewan are definitely oligotrophic. Five others on the glacial drift south of the Shield are clearly eutrophic and two across the boundary are intermediate. From the analysis of extensive data, five physical and three biological criteria have been selected which tend to agree in indicating the trophic nature and relative productivity of these lakes.
