Issued also in French under title: Étude de reconnaissance des caractéristiques chimiques et biologiques de la limnologie de quatre grands lacs du bassin du fleuve Yukon. Includes bibliographical references. "Limnological surveys were conducted on four large lakes (Atlin, Tagish, Marsh and Laberge) of the Yukon River system on four occasions during 1982 and 1983. Nutrient levels are very low, as are algal and zooplankton biomass, indicating that the lakes are ultraoligotrophic. Physical factors (i.e. flushing, turbidity, etc.) have pronounced effects on the chemistry and biology of these lakes"--Abstract.
