Cirque Lake Outflow, Dale Creek & Tributary and Tsichu River Tributary Sampling
Principal Investigator: Ponsford, Ian
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5975. To collect baseline data related to water quality, hydrology, and fish habitat from 11 different locations at the outflow of Cirque Lake and along Dale Creek, as well as tributaries of both Dale Creek and the Tsichu River. Baseline data will be obtained from the surface water quality monitoring stations WR-1, WR-2, W...


Temporal trend studies of trace metals and halogenated organic contaminants (HOCs) including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT (2024-2025)
Principal Investigator: Stern, Gary
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5906. Short-term goals are to determine if burbot contaminant concentrations: • Are above or below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish). Annual data will be provided to NWT Health and Social Services for evaluation; • Are associated with dietary indicators, i.e. stable isotope ratio data (15N, 1...


Spatial and long-term trends in persistent organic contaminants and metals in fish from the Northwest Territories
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2023 2022 2017 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005
Summary: This licence has been issued for the scientific research application No. 5669. This research study is continuing to investigate whether contaminant (mercury, other metals, persistent organic contaminants) levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake, which the research team has been studying since the early 1990s. The team plans to arrange collection...


Temporal trend studies of trace metals and halogenated organic contaminants (HOCs) including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT
Principal Investigator: Stern, Gary
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5414. The short-term goals are to determine if burbot contaminant concentrations: 1) Remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish). The research will provide annual data to NWT Health and Social Services for evaluation; 2) Are associated with dietary indicators, i.e. stable isotope ratio data (...


Contaminants (PAHs, mercury) in the Mackenzie River and fish health assessments: implementation of classic and new molecular screening tools for environmental monitoring and stressor assessment
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5333. This study will determine the concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) in small-bodied fish in the Norman Wells/Imperial area near nature oil seeps and industrial activities with comparisons to be made with upstream (Tulita area) and downstream (Fort Good Hope) areas. The research team will also asses...


Spatial and long-term trends in persistent organic contaminants and metals in fish from the Northwest Territories
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5031. The study is continuing to investigate whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which we have been studying since the early 1990s. The research team plans to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area and also plans ...


Aquatic Studies along the Mackenzie River and its Tributaries
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2005
Summary: This study is designed to investigate various measures of small fish health at a number of locations along the Mackenzie River. The researchers want to find out if small fish health is different near oil seepages and the islands at Norman Wells than in other parts of the river. Also, the researchers will investigate fish and benthic invertebrate abundance and species composition at selected strea...


2003 Winter Aquatic Studies in the Sahtu Settlement Area
Principal Investigator: Povey, Andrew
Licensed Year(s): 2004 2003
Summary: Surveys of selected streams and lakes along the proposed pipeline corridor within the Sahtu Settlement Area will be conducted this winter. This will be done to assess overwintering conditions for fish and watercourse freezing conditions in the vicinity...


Investigating the Importance of Water Chemistry on Mercury Concentration in Fish from Mackenzie River Basin Lakes
Principal Investigator: Stephens, Glen
Licensed Year(s): 1998
Summary: The objective of the work is to characterize the water chemistry of lakes with reported elevated concentrations of mercury in fish from the Mackenzie River Valley, which were sampled as part of the Department of Fisheries & Oceans (DFO) fisheries management plan. This would help to establish if there is any relationship between basic lake water chemistry and mercury levels in fish which could be u...


Mackenzie River Watershed Survey of Fish Harvesters
Principal Investigator: Little, Lois M.
Licensed Year(s): 1988
Summary: The Dene Nation asked the Department of Indian and Northern Affairs to conduct a survey about fish caught in the Mackenzie Valley. Lutra Assoc. will be training someone in each community to ask questions like this: How many fish are not normal and why? Where are these caught? How much fish are people eating? Is this changing because more abnormal fish are being caught? What would happen if pe...
