Summary: The objective of this study is to determine fish presence, distribution and abundance in water bodies in the Project area. The age/size frequency distribution, wintering habitat and spawning habitat will be examined, and the metal burdens determined, along with fish presence and distribution along road and bridge crossings. The study will use a combination of methods including minnow traps, fyk...

Summary: Proposed work includes an aquatic study and risk assessment. Sampling will occur over a two week period in mid-August. Samples will be collected with gill nets. Target species include lake trout and northern pike. Tissue samples from fish representing all age classes will be collected (up to twenty fish per species per lake). Sediment and benthic invertebrate samples may also be collected, dependi...

Summary: Research team members will be transported to site via Diavik air charters. Field collections will be conducted from boats provided by Diavik. The different collection gear types will be gillnets, trapnets, and angling. The target sample sizes at each of three sites will be a maximum of 100 lake trout, and 100 whitefish or cisco (to be determined based on catch success rates). Twenty fish of eac...

Summary: This work is being done to assist with the development of a future aquatic effects monitoring program for the mine that will meet the terms of the recently promulgated federal Metal Mining Effluent Regulations. The survey data will be provided in support...

Principal Investigator: Thomas, Craig J
Licensed Year(s): 2000
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...
