Zach Pond 1997 Fisheries Resource and Habitat Survey (BHP Billiton, April 1998)
1 April 1998Report
This baseline fisheries resource and habitat survey of Zach Pond, a small oligotrophic tundra lake overlying a kimberlite pipe 11 km southeast of the Ekati Diamond Mine, documents fish populations, water quality, and habitat conditions prior to potential bulk sample drilling activities. The survey found an isolated burbot population with minimal available spawning habitat, clear slightly acidic water with low nutrient levels, and a dry outflow stream with no fish habitat.

1 April 1998Report
This baseline fisheries resource and habitat survey of Sable Lake (8.9 ha), conducted in 1997 for BHP Diamonds Inc., documents water quality, fish community composition, and habitat conditions in preparation for potential future mining of a kimberlite pipe underlying the lake. The survey found the lake to be oligotrophic with 110 lake trout and 2 slimy sculpin, relatively low catch rates, boulder-dominated littoral habitat with minimal spawning areas, and a completely isolated fish community due to impassable inflow and outflow streams.
