Objective(s): To collect bathymetry information on lakes to estimate water volume of each lake and therefore maximum volume of water which can be withdrawn. A subset of lakes will likely be assessed for fish presence.
Project Description: The objective of this research is to collect bathymetry information on lakes to estimate water volume of each lake and therefore maximum volume of water which can be withdrawn. A subset of lakes will also be assessed for fish presence. A gps-referenced depth sounder will be used to record detailed lake depth information. On a subset of lakes the research team will utilize several fish capture techniques to assess for fish presence. Fishing techniques used will likely consist of backpack electrofishing, gill netting, seining, and minnow trapping and angling. Scuba surveys and underwater video photograph may also be applied. Fishing will be conducted until one or more fish are captured. Fish will be released immediately after capture. Species of fish and approximate size will be documented and a photograph will be taken. This work is being conducted to collect data needed by DFO related to the permitting of a proposed mine. The mine, once operational, will provide economic social benefits to local communities. Results will be provided in submissions to the Mackenzie Valley Review Board (MVLWB) and Parks Canada in support of permits, and will be circulated for comment to communities listed for engagement as part of the permit process. The fieldwork for this study will be conducted from June 10, 2012 to June 30, 2012.
