Licensed Year(s): 2014 2013 2012 2011 2010
Summary: The objectives of this project are to draw together multiple sources of information so that the research team may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and int...


Mercury Concentration of Two Lakes on the Yellowknife River System Affected by the Bluefish Hydrodam
Principal Investigator: Puznicki, Wayne
Licensed Year(s): 1997
Summary: The objective of the study is to assess the concentration of mercury in fish, water and sediment in Bluefish and Duncan Lakes; to provide information to the Yellowknives Dene First Nation to make decisions relating to the use of fish and water from these lakes; and to correlate traditional knowledge with scientific data. Bluefish & Duncan Lakes are about 50 km to the northeast of Yellowknife. Tr...
