Aquatic Effects Monitoring Program (AEMP) Technical Report, Ekati Diamond Mine (BHP Billiton, December 2002)
The 2002 Aquatic Effects Monitoring Program technical report evaluates baseline and post-baseline monitoring data from the Koala and King-Cujo watersheds to assess impacts of the Ekati Diamond Mine on aquatic environments. The report finds that while mine activities caused localized changes in water quality parameters within both watersheds, no major adverse ecological effects were observed in biological communities, though some elevated nutrient levels and phytoplankton biomass changes were detected in specific receiving lakes.
