Summary: The research team will be transported to Long Lake by aircraft, and will travel by truck on the mine site. Sample collection will be carried out using a motorized boat. Water and phytoplankton samples will be collected using a 10 L Go-Flo water sampler. Zooplankton samples will be collected using a zooplankton net. There are three taxa of freshwater zooplankton that may be collected from Long ...

Summary: This is a preliminary fisheries study to confirm 1989 baseline studies and to assist in impact assessment for Abandonment and Restoration (A & R) Plan for site closure. The researchers will conduct habitat assessments along drainages of Steeves Lake and Indin River (i.e. fish habitat mapping, assessment of habitat potential, 'spot check' confirmation of fish communities, the collection of instant...

Summary: Recently BHP Diamonds Canada has "dewatered" a number of lakes and created a diversion channel to re-route water around two open pit mines. The purpose of this study is to compare the effectiveness of the diversion canal as habitat before and after it is enhanced with fish habitat structures and also in relation to natural streams in the area. In early spring Arctic grayling will be captured in we...

Principal Investigator: Tyson, J. David
Licensed Year(s): 1999
Summary: The objectives of this project are to: 1. determine the presence of fishes in selected waterbodies on the BHP Diamonds claim block, 2. determine the extent of utilization of streams by fishes as migration routes, and 3. inventory the quantity and quality of fish habitat in waterbodies supporting fishes. The potential species involved in this monitoring program are Arctic grayling, burbot, lake tr...

Licensed Year(s): 1996
Summary: The Lupin study site is one of seven mine sites being investigated across Canada. Receiving water samples will be collected for chemistry (total and dissolved metals) and toxicity testing. To ensure that a well-defined chemical gradient exists water and sediment will be collected from reference and exposure stations at the study site. Sediment samples will be collected for chemistry (total orga...

Licensed Year(s): 1996 1995
Summary: Methods of data collection will include water quality and bottom sampling in Lac de Gras and Lac du Sauvage; automatic and manual water level recordings; bathometric work; automatic weather stations and the monitoring of air-borne particles and visibility; continuation of baseline studies of soils and terrain, and vegetation; fish population, habitat, health, and spawning habits studies; baseline ...

Summary: As part of overall reclamation goals of BHP, the 1996 season will focus on three components. Vegetation response will be assessed in August using the point-frame method. Within the legume, indigenous seed and shrub cutting plots, plant density will be recorded. Soil samples in replicates of three will be collected from each treatment to analyze physical and chemical characteristics. Secondly, ...

Principal Investigator: Reed, Shawna
Licensed Year(s): 1995
Summary: The researchers will be utilizing the following techniques for assessing aquatic biota and fish habitat utilization: gillnetting (various sizes and meshes), trapnetting (mark-recapture program), minnow-trapping and electroshocking (backpack model). A select number of fish will also be retained for aging (using otoliths), tissue metals concentration and diet analysis....

Principal Investigator: Clayton, Terry
Licensed Year(s): 1993
Summary: The researchers have been commissioned by Echo Bay Mines Ltd. to conduct a study on young-of-the-year arctic grayling which are located in a small creek near a tailings pond of the Lupin mine site. Approximately 100 hatched arctic grayling will be caught in order that contaminant analyses can be conducted on the tissues....

Principal Investigator: Ash, Gary R.
Licensed Year(s): 1994 1993 1992
Summary: The researchers will be conducting surveys in the areas south and east of Coppermine in order to provide basic information about the fish species and habitat. This study is being conducted on behalf of Minnova Inc. in order to provide information in monitoring the impacts of development in the area....
