The purpose of this study was to determine the effects on aquatic biota of dissolved metals from the copper/lead/zinc mines operated by Westmin Resources Ltd. near the south end of Buttle Lake. This investigation was designed to try to answer some questions particularly in regard to lake biology for which no previous information was available. The questions considered were (1) Is there any evidence of bioaccumulation of metals in components of the food chain: phytoplankton, zooplankton, benthos, and fish, (2) What is the effect of the metal concentrations on growth rates and standing crops of phytoplankton and zooplankton, and (3) What are the spatial variations (along the lake system and with depth) and temporal variation of metal concentrations and biological production? Which hydrological and limnological characteristics affect these distribution patterns?
