Habitat modelling reveals four times more juvenile fish are expected in Hazeltine Creek post-remediation efforts
Mount Polley Mining Corporation is pleased to report that fish populations are thriving at Mount Polley. Further, the current habitat of upper Hazeltine Creek is over 1.5 times more likely to spawn fish than the pre-breach habitat. A recent report prepared by Golder, Mount Polley’s Environmental Consultant, reveals that the fish population in Hazeltine Creek is increasing as a result of the remediation efforts made by the Mount Polley Habitat Remediation Working Group* since 2014. Computer modelling of the fish population projects that there could be up to four times more juvenile trout in Hazeltine Creek in 2031 than in 2014.
“By May 2015 the water in Hazeltine Creek was running clear, and the bugs – invertebrates that provide food for fish – were starting to grow in the creek, so it was decided that the installation of new fish habitat could begin and this work started in 2016,” stated Lee Nikl, Principal and Senior Environmental Scientist – Mine Water and Environment Group at Golder. “By late 2017, fish were let back into the creek.”
We expect there to be almost twice as many juvenile trout in Hazeltine Creek by 2022. The new report uncovers that this is an outcome of the remediated habitat features in the creek, as well as the unobstructed conditions for upstream passage of fish, which are expected to persist in the long term. The Habitat Remediation Working Group has been guiding and overseeing habitat remediation since 2014 and “the design objectives and the designs themselves are the outcome of collaborative design with the Habitat Remediation Working Group”, said Nikl. “The focus of the remediation effort at Mount Polley has been to repair and rehabilitate Hazeltine Creek so that it becomes a self-sustaining, productive fish habitat.” said Brian Kynoch, President of Imperial Metals.
