Understanding the potential impact of metals in aquatic systems.
Principal Investigator: McGeer, Jim
Licenced Year(s): 2017
Summary: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of metals. Three types of sample collections are proposed. These would be done at selected sites along the Ingraham Trail (highway 4) east of Yellowknife. The...


The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The objectives of our study are to 1) establish the importance of lake connectivity in determining the community composition and species richness of the invertebrate community of a lake, and the contribution of lakes of differing connectivity to the regional diversity of the Mackenzie Delta, 2) characterize the response of invertebrate communities to changing peak flood levels to allow prediction ...


NTPC Bluefish Hydro Repairs
Principal Investigator: Panayi, Damian
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective is to describe the aquatic environment in the Yellowknife River between Bluefish Lake and Prosperous Lake as per the Fisheries Authorization and the Water Licence. This may include investigating aquatic vegetation, water quality and quantity, benthic invertebrates, fish and substrate. The results will be used to determine the most suitable means of fish habitat compensation or produc...


Aquatic Environmental Effects Monitoring - Flat River at Cantung Mine
Principal Investigator: Hoos, Rick
Licenced Year(s): 2012 2009 2002
Summary: The objectives of this research are: (1) to determine length, weight, and general condition of 100 fish and tissue analysis of not more than 10 fish (Slimy Sculpin- Cottus cognatus) per site at five site locations in the Flat River: two locations upstream of the CanTung mine site, one adjacent to the mine site and at two locations downstream of the mine site; and, (2) to determine sediment and w...


Biological Studies of Waters Along the Proposed Mackenzie Gas Project Pipeline Route - Sahtu Settlement Region
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2008
Summary: The research will examine streams possibly affected by the proposed Mackenzie Gas Project pipeline, and streams that can serve as future control/reference sites. Measurements of stream nutrients, metals in stream water, water quality (DO, pH, conductivity, etc.), stream characteristics (flow, width, depth, etc.) and aquatic invertebrate abundance/species composition will be completed. Possible t...


Aquatic Effects Monitoring Program 2007
Principal Investigator: Wytrychowski, Scott I
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: The purpose of the 2007 AEMP is to initiate a long term aquatics sampling program in order to produce a data set that will be used in trend analyses to track the overall effects of the project on the aquatic ecosystem of Lac de Gras and to confirm predictions made during the EA. This is achieved by conducting consistent annual sampling at fixed mid-field and far-field stations for which baseline c...


Characterization of the reference condition of northern biota and assessment of potential changes due to mining
Principal Investigator: Dube, Monique G
Licenced Year(s): 2006
Summary: The objectives of this research are three-fold: 1) to determine the natural variability of benthic invertebrate and fish communities at sites free of human impact; 2) to determine any changes in these due to mining activity relevant to regional variability; and 3) to establish dose response relationships and critical thresholds for stressors including mine effluent, ammonia, a hydrocarbon indicato...


2006 Aquatic Monitoring Program
Principal Investigator: Wen, Marc
Licenced Year(s): 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003
Summary: The proposed fieldwork is intended to characterize baseline and post-baseline conditions in the lakes and streams near areas of current and pending mining activity. In anticipation of future infrastructure development, baseline data will be collected in those areas. Fish populations of the Panda Diversion Channel (PDC) will continue to be monitored, and compared with the productivity of two nearby...


Aquatic Studies in support of the Discovery Mine Remediation Work
Principal Investigator: Ford, Bruce S
Licenced Year(s): 2005
Summary: This study involves fish sampling to determine relative abundance and levels of mercury and other metals in fish tissue in Giauque Lake, Thistlethwaite Lake and Control Lake A, as well as benthic invertebrate sampling and water quality sampling in the three lakes to complement the fish sampling. 3 sites in Giauque, 3 in Thistlethwaite and one in Control Lake A will be recorded. Captured fish will ...


Environmental Effects Monitoring for Miramar Con and Giant Mines
Principal Investigator: Caughill, Dave
Licenced Year(s): 2004 2003
Summary: The main objective of this study is to characterize environmental conditions and supplement existing environmental information for possible use in long-term (i.e., multi-year) Environmental Effects Monitoring (EEM) programs as required of the Giant and C...
