Supporting fish habitat restoration

Following the flood in 2013, Allison Creek in southwestern Alberta was damaged. This creek provides critical habitat for the Westslope Cutthroat Trout—a species protected under the Species at Risk Act, and important habitat for Bull Trout, protected under the Alberta Wildlife Act. With the creek greatly in need of restoration, Alberta Environment and Parks looked to our team for help.

Our team designed bioengineered fish habitat features to repair and enhance fish habitat within sensitive watersheds. The designs included wood cribwalls complete with plantings in the upper layers and locally sourced live poplar in the lower layers, accelerating the establishment of riparian vegetation, and creating habitat cover. We added a tree revetment anchored to the bank using locally sourced trees and native cobbles as well as wood debris features that are arranged as a network of debris to reduce erosion and stabilize the banks. Using locally sourced gravels and riparian vegetation, we re-established and re-created more than 100 metres of the channel within the headwaters, repairing and directly improving the habitat quality for the threatened fish species.

Upon completion, feedback from the client let us know our work positively impacted the fish habitat.
