Restoring an important fish habitat

In the 1950s, following severe flooding that devastated the downtown and private properties, the creek crossing the city of Penticton was channelized and lined with concrete to eliminate floodplains. Although this infrastructure served its purpose, native fish populations of rainbow trout, kokanee and sockeye salmon decreased. Over time, the concrete also deteriorated, and restoration was identified as a priority.  

We were engaged by the City to complete a comprehensive analysis of the creek and work with the Penticton Creek Restoration Committee to carry out the phased restoration works. We conducted vegetation, wildlife, and fish habitat surveys, and coordinated the many required environmental permits and approvals. Our team included hydrotechnical engineers, who utilized hydraulic flood modeling to determine elevations and velocities for resiliency.

The Okanagan Nation Alliance, Fly Fishers Association, and Penticton Indian Band were key stakeholders in the process. The team worked with Penticton Indian Band who undertook archaeological mapping prior to construction to identify known or potential sites and monitor for unidentified and uncovered sites.  

The results? The creek was revitalized—fish passage and spawning were drastically improved, critical flood and erosion protection was enhanced, and native trees and shrubs were planted. Only days after works were completed, we saw fish swimming up the newly constructed spawning pools!
