Panda Diversion Channel Monitoring Program Appendices, Ekati Diamond Mine (BHP Billiton, December 2001)
1 January 2002Report
This comprehensive 2001 monitoring report for the Panda Diversion Channel at the Ekati Diamond Mine documents stream hydrology, fish populations (especially Arctic grayling and lake trout), larval fish distribution, benthic invertebrate communities, and habitat conditions across multiple assessment sites. The appendices provide detailed data on fish capture records, water quality measurements, substrate composition, and photographic documentation of habitat conditions during both high and low flow periods.

Email transmittal and review paper "Oxygen in Lakes North of the Tree Line — A Review" forwarded by Zabey Nevitt (Independent Environmental Monitoring Agency, monitor@yk.com) to Robin Staples (May 23 / 31 2001), originally from Camille Douglas (BHP) referencing work by H.E. Welch. Discusses winter respiration rates of Canadian Arctic lakes (0.08-0.45 g O2/m²/d), winter oxygen depletion, P&N Lake oxygen isopleths (Welch and Legault 1986), and the ~2-3 mg/L dissolved-oxygen threshold below which most Arctic fish die.
