Wolfe Creek Fish Habitat Offsetting Project

Client

Copper Mountain Mine

Location

Princeton, British Columbia

Project Duration

2015 – ongoing

Background

The East and West Dams of the Copper Mountain Mine Tailings Management Facility are to be raised on an annual basis to an elevation of 997 m as per amended Mines Act Permit M-29. To protect the toe of the East Dam and prevent encroachment into Wolfe Creek the mine realigned 2.9 km of Wolfe Creek, of which 915 m was fish-bearing. To offset residual impacts to fish habitat the mine developed the Wolfe Creek Fish Habitat Offsetting Plan (FHOP) in support of regulatory approvals. The FHOP was designed to provide higher quality habitat for rainbow trout than what was impacted by the Wolfe Creek realignment and includes new meandering run-pool-riffle channels, spawning riffles, and overwintering and summer rearing ponds.
