About this location

  • Water body type Lake
  • Dataset Missanabie Cree First Nation - Dog Lake Head Waters Monitoring Program, NORDIK Institute
  • Data collector Ty Hourtovenko
  • Location description Magino Mine Site discharges the effluent into Otto Lake, after a series of passive water management. Diffusers at the end of the discharge pipe help with the dilution process. Testing the narrows before water flows into Herman Lake serves as a prefect location to determine potential contamination concentrations entering the much larger body of water of Herman Lake.
