Aquatic Effects Monitoring Program (AEMP) Appendix A, Evaluation of Effects Data Report, Draft for Public Review, Ekati Diamond Mine (BHP Billiton, February 2005)
This is the 2004 Aquatic Effects Monitoring Program (AEMP) evaluation report for the Ekati Diamond Mine, assessing changes in aquatic ecosystems in the Koala and King-Cujo watersheds and their downstream areas (Lac de Gras and Lac du Sauvage). The report presents detailed monitoring of water quality, physical limnology, and biological communities, finding that while some water quality parameters showed measurable changes due to facility discharges (LLCF and KPSF), all values remained below Canadian guidelines and minimal biological effects were detected in downstream waterbodies.
