Risk Assessment of Fox Mine Water Discharge in the Long Lake Containment Facility, Ekati Diamond Mine (BHP Billiton, January 2004)
1 January 2004Report
This risk assessment evaluates the relative risk to aquatic life downstream of the Long Lake Containment Facility (LLCF) from discharging Fox Pit mine water into either Cell C or Cell D over the operational life of the Ekati Diamond Mine through 2015. Using mass balance modelling and risk quotient analysis, the assessment concludes that discharge into either cell will result in compliance with water licence effluent requirements, with no significant differences in predicted water quality between the two scenarios.

Prediction of Water Quality for the Long Lake Containment Facility (LLCF), Ekati Diamond Mine (BHP Billiton, January 2004)
1 January 2004Report
This report presents revised water quality prediction modelling for the Long Lake Containment Facility (LLCF) at Ekati Diamond Mine, comparing two scenarios for discharge of treated Fox Pit mine water into different cells. The revised mass balance model incorporates updated site water balance data, treatment removal factors, and cell removal factors to predict discharge water quality concentrations for 26 parameters from 2003 through 2015, with all predicted maximum concentrations remaining below Water Licence effluent requirements.

Panda Diversion Channel Monitoring Program, Draft, Ekati Diamond Mine (BHP Billiton, December 2003)
1 December 2003Report
This report documents the sixth year (2003) of monitoring fish populations in the Panda Diversion Channel (PDC), a man-made compensatory stream constructed in 1998 at the Ekati Diamond Mine. The study measured the productivity of the PDC relative to two reference streams (Pigeon and Polar-Vulture) by monitoring Arctic grayling spawning success, fry emergence, growth rates, survival, and outmigration, revealing that while the PDC supports high spawner densities, fry survival and growth rates were lower than reference streams due to incomplete ecosystem seasoning and density-dependent effects.

Survey of Fish Populations in Cell E of the Long Lake Containment Facility, Ekati Diamond Mine (BHP Billiton, October 2003)
1 October 2003Report
This report documents a fish population survey of Cell E of the Long Lake Containment Facility at the Ekati Diamond Mine conducted in August 2003, comparing 22 biological variables with pre-development conditions from 1994 and 1997 to assess the facility's impacts on fish communities. The survey found that most fish population characteristics showed no significant change, with higher catch rates of adult fish but evidence of reduced juvenile recruitment possibly due to loss of spawning habitat caused by dyke construction.
