September site tour with the Habitat Remediation Working Group

The remediation of Hazeltine Creek has been planned and advanced through the direct collaboration of Mount Polley mine employees, government agencies, First Nations and their technical advisors. This collective is called the Habitat Remediation Working Group (HRWG).

Recently, members of Mount Polley mine, Golder Associates Ltd, FLNRO (Ministry of Forests, Lands, Natural Resource Operations and Rural Development) and the Xatśūll First Nation attended a September 2020 HRWG tour.

On the tour the HRWG inspected the construction of habitat features in Lower Hazeltine Creek. The group also inspected the weir and fish ladder at Polley Lake, the functioning spawning habitat in Upper Hazeltine Creek and the terrestrial plant growth in Polley Flats.

The group viewed all stages of remediation, from installation of habitat features to a remediated ecosystem in Upper Hazeltine Creek that is maturing into a self-sustaining landscape used by all manners of life forms.

Discussions on the tour included:
• Local nursery plant sources;
• Local contractors support in the remediation efforts;
• Reflections on how far the remediation has advanced;
• Reopening plans for the mine;
• Plans for the continued use of the weir on Polley Lake for flood control and fish rearing in Hazeltine Creek until the plants in the terrestrial flood plain mature; and
• In stream habitat features installed are potentially superior to those that existed pre-2014.

Below are some photos from the tour (September 2020).
