Meteorology, Hydrology and Water Quality 1995 Baseline Study Update (BHP Billiton, December 1995)
This 1995 baseline study update reports meteorological, hydrological, and water quality monitoring for the NWT Diamonds Project (Ekati Mine) in the Koala/Long Lake watershed. The year was characterized by significantly higher precipitation (40% above 1994 and baseline estimates), resulting in elevated streamflows and lake levels that approached 1-in-100-year flood event magnitudes, with observed peak flows correlating well with regional historical data; water quality analysis showed localized effects in Kodiak Lake and elevated metals in the Panda Diversion Channel, though no significant changes were observed in Slipper Lake, the watershed outlet.
