Fish habitat restauration at the Louvem Mine in Val-d’Or

The Louvem Mine is a former copper mine acquired by Teck Resources. In 2010, the company wanted to reintroduce a 150-metre section of a stream into its original bed and restore the fish habitat. The work included excavating, widening the drainage channel, stabilizing banks, creating various flow patterns, adding a deep bay and developing spawning grounds and fish shelters.

Client: Teck Resources
Location: Val-d’Or, Québec

OUR EXPERTS’ SOLUTIONS

Our environment experts, Biofilia, performed biological studies and physical surveys of the study area to develop restoration designs for the receiving environment, which included restoring a drainage channel for a major watercourse as well as restoring functional aquatic habitats for fish, amphibians and generally improving its water quality. This habitat restoration was a ministerial environmental requirement tied to the mine closure. The mandate included:

  • Biophysical studies of the receiving environment:
    – Aquatic and riparian vegetation assessments
    – Studies of fish populations and their habitats
    – Aquatic macroinvertebrates sampling
    – Inventories of rare species

  • Plan and specifications design to restore and develop aquatic and riparian habitats

  • Environmental assessment and coordination of provincial authorization applications

  • Environmental monitoring and supervision during construction
