Aquatic Effects Monitoring Program (AEMP) Appendix A, Evaluation of Effects Data Report, Draft for Public Review, Ekati Diamond Mine (BHP Billiton, February 2005)
1 February 2005Report
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.

Application of the NWT Winter Water Withdrawal Protocol with Bathymetric Profiles of Select Small Lakes in the Mackenzie Delta Region (DFO, 2005)
31 January 2005Report
This technical report documents the application of the Department of Fisheries and Oceans Protocol for Winter Water Withdrawal in the Northwest Territories, presenting bathymetric surveys and volume calculations for 55 small lakes in the Mackenzie Delta region to support industrial water users and protect over-wintering fish habitat. The report demonstrates how sampling effort in bathymetric surveys directly affects accuracy of lake volume estimates and provides guidance for determining safe water withdrawal limits.

Commentary on the Management of Fish Habitat in Northern Canada: Information Requirements and Policy Considerations Regarding Diamond, Oil Sands and Placer Mining, Summary Report, Canadian Technical Report of Fisheries and Aquatic Sciences 2607 (DFO, 2005)
~2005Report
Approximate date — inferred from filename
This technical report examines fish habitat management in northern Canada with focus on diamond, oil sands, and placer mining operations, identifying critical knowledge gaps and policy considerations needed to comply with the Fisheries Act and achieve 'no net loss' of fish habitat productive capacity. The report documents that 70 lakes have been or are proposed to be eliminated for mining use since the 1950s, with 62% approved in the last decade, and recommends integrated research, monitoring, and collaborative management approaches to address deficiencies in Arctic aquatic ecology understanding.

Independent Third-Party Review of the Aquatic Effects Monitoring Program (AEMP) (Zajdlik & Associates, 2005)
~2005Report
Approximate date — inferred from filename
Independent 3rd-party review of the Ekati Diamond Mine's Aquatic Effects Monitoring Program (AEMP) conducted by Zajdlik & Associates for 2002 monitoring data, evaluating statistical treatment of nitrate, copper, and zooplankton measurements to assess environmental changes downstream of the Low-Level Containment Facility. The review identifies strengths in BHPB's comprehensive monitoring program while recommending improvements in data handling procedures, alternative statistical approaches, and use of gradient and multivariate analyses.
