Ecological Risk Assessment of Copper within the Koala Watershed, Ekati Diamond Mine (BHP Billiton, October 2001)
1 October 2001Report
A screening-level ecological risk assessment of copper in the Koala Watershed at the Ekati Diamond Mine evaluating whether copper concentrations in water and sediments pose risks to aquatic organisms. The assessment concludes that four locations (Panda Diversion Channel, Kodiak Lake, Kodiak-Little Stream, and Little Lake) present low to negligible risk, with all other locations showing negligible risk of adverse ecological effects from copper exposure.

Panda Diversion Channel Monitoring Program Technical Report, Ekati Diamond Mine (BHP Billiton, January 2000)
1 January 2000Report
This is the second year (1999) monitoring report for the Panda Diversion Channel at Ekati Diamond Mine, assessing the performance of constructed fish habitat enhancements and channel stability following a major freshet event. The report documents hydrology, spring fish migration, larval emergence, habitat assessments, channel stability, benthic invertebrates, and periphyton communities, comparing 1999 results with 1998 baseline data and concluding that Arctic grayling and other fish species are utilizing the channel and enhancements successfully despite some areas of channel degradation from exaggerated peak flows.

Kodiak Lake Sewage Effects Study Technical Report, Ekati Diamond Mine (BHP Billiton, March 1999)
1 March 1999Report
This technical report presents the 1998 Kodiak Lake Sewage Effects Study, the second year of a three-year monitoring program examining the effects of treated sewage effluent discharge on water quality, sediment quality, and aquatic life in Kodiak Lake and Kodiak-Little Stream. The study documents increased water residence time, elevated nutrient loading, enhanced lake productivity, and reduced winter dissolved oxygen levels, leading BHP to decide to redirect sewage discharge from Kodiak Lake to the Long Lake containment area.
