EKATI Engineering and Environmental Monitoring Programs
Principal Investigator: Hayward, April
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The main objectives of the field work for 2017 to 2021 will be:1) to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment and air quality; and 2) to provide baseline data for areas where mine development may occur in the future. In winter, water samples will be collected under ice using a 2.5L Niskin (a cylindrical PVC water sampler). During the week o...


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: This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Permafrost thaw in lake catchments may cause increased transport of organic carbon and dissolved nutrients to lakes with effects on the hydrology and water chemistry of lake environments. Patterned ground marked by ice-wedge polygons is f...


Examination of distribution and density of juvenile Dolly Varden char in Fish Creek (Rat River)
Principal Investigator: Maier, Kris
Licenced Year(s): 2016 2015 2014
Summary: The research team seek to build on the 2014 success in monitoring habitats and using electrofishing to assess juvenile Dolly Varden occupancy. Specific objectives include: 1) to continue implementing a community-based monitoring program to monitor essential habitats; 2) to further delineate the spatial distribution of juvenile char in the Fish Creek watershed; and, 3) to establish a length at age ...


Fish Inventory Study in EL494
Principal Investigator: Hansen, Ken
Licenced Year(s): 2015
Summary: The objective of the project is to identify the fish species present, gather population data on surveyed fish species, assess fish habitat characteristics, and identify benthic invertebrate species present in waterbodies in the area of Husky’s proposed exploration activity. Five streams and nine lakes are proposed to be assessed. Backpack electrofishing and fyke nets will be used to assess the ...


2008 Field Monitoring – Matthews Lake and Area Fish Habitat Restoration and Enhancement Project
Principal Investigator: Scott, Janet L
Licenced Year(s): 2008
Summary: This licence was issued for the application no. 802. The objective of the 2008 fieldwork is to monitor vegetation, invertebrates, and fish populations associated with lakeshore and stream habitat restoration and enhancement. Data will be used to evaluate the continuing success and effectiveness of restored or enhanced stream and lakeshore habitats against control sites, through time. Field ...


2007 Field Monitoring - Matthews Lake and Area Fish Habitat Restoration and Enhancement Project
Principal Investigator: Van Humbeck, Joe
Licenced Year(s): 2007
Summary: The objective of the 2007 portion of the project is to monitor control sites and treatment sites, and collect information on the habitat utilization. Data collected will be used to evaluate the continued success and effectiveness of the habitat construction and enhancement. Field crews will fly to Matthews Lake, landing either on the runway or the lake. The Treeline Lodge, where the research te...


Distribution and Habitat Use of Sensitive Fish Species along the Mackenzie River Valley
Principal Investigator: Mochnacz, Neil
Licenced Year(s): 2006
Summary: The Mackenzie Gas Pipeline will cross more than 600 tributaries of the Mackenzie River, ranging from small (< 1 m) vegetated swales to large rivers. All construction methods, with the exception of trenchless drilling, will disturb the bed and banks of the rivers they cross. Fish habitat use and distribution has not been studied in sufficient detail. Fish will be captured and identified for spec...


Paleohydrology and Paleoecology of the Slave River Delta
Principal Investigator: Wolfe, Brent BBW
Licenced Year(s): 2007 2006 2005 2004 2003 2002
Summary: This research program focuses on high-resolution reconstruction of past hydrology, ecology and climate of the Peace-Athabasca (PAD) and Slave River deltas (SRD) from natural archives, including lake sediments and tree rings, supported by comprehensive field-based studies of modern hydrology, limnology and aquatic ecology. The PAD and SRD have broad ecological and cultural significance and are ecos...


2005 Summer and Fall Aquatic Studies in the Sahtu Settlement Area
Principal Investigator: Povey, Andrew
Licenced Year(s): 2005 2004 2003 2002
Summary: Imperial Oil Resources Ltd., Aboriginal Pipeline Group, ConocoPhillips Canada (North) Ltd., Shell Canada Limited, and ExxonMobil Canada Properties are continuing baseline studies begun in 2001 as part of the Mackenzie Gas Project. All of the aquatic studies will be conducted by three- or four-person crews supported by helicopter, or if possible, by boat. Each crew will include a local assistant. T...


Ecological Conditions in the Proposed Discharge Route of the Colomac Mine, NT
Principal Investigator: McGurk, Michael
Licenced Year(s): 2005 2004
Summary: The researchers will measure water quality, aquatic ecology and the status of fish populations in ponds and lakes along the proposed discharge route of mine water from the Colomac Mine (North Pond, L-Shaped Lake, Paddle Lake, Lake 315, and Lower Lake) and compare those data with data collected from reference lakes (Steeves Lake, Baton Lake, and Spanner Lake). Work will include taking three samples...
