Notice of permit

Regional or Local Number: DFO-17-HCAA-00374

Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. DFO-17-HCAA-00374 is issued.

Activity necessary or beneficial to the species

The proposed activity involves the restoration of four flood-impacted sites along Allison Creek, to enhance fish habitat for the benefit of Westslope Cutthroat Trout. The proposed area was identified as high priority under the Fisheries Habitat Enhancement and Sustainability Program (FISHES) due to widespread habitat degradation and sediment inputs in the area. The proposed works involve the installation of various sediment and erosion control (ESC) measures, including a 20 m tree revetment, a 31 m wood and cobble toe, crib walls (7 m on the east bank, 18 m on the west bank), live willow stakes, soil wraps, and the revegetation and reshaping of 10 m of gravel bar. The work requires isolation of the local work area and for flows to be maintained.

Issuing Authority: Department of Fisheries and Oceans

Authority Used:

  • Species at Risk Act

Location of Activity (province, territory or ocean):

  • Alberta

Affected Species:

a) Alternatives: The sites proposed for enhancement in Allison Creek were selected using an Evaluation, Scoring and Ranking Computer Model (ESRM) developed by the FISHES program. The ESRM identified a number of priority sites within the Allison Creek Watershed, which were broken down into habitat units and ranked according to a priority score. The proposed enhancements for the selected sites have been designed to reduce sedimentation, provide habitat for Westslope Cutthroat Trout and other fish species, and restore riparian vegetation in an attempt to restore the quality of the Allison Creek watershed. The sites selected for enhancement were determined to have high priority by the ESRM developed by FISHES. b) Measures to minimize impact: Mitigation includes: isolation of in-stream works; performing the majority of in-stream works outside of the Restricted Activity Period; the immediate rescue and relocation of fishes prior to construction, to be performed by/under the supervision of qualified personnel that have experience with Westslope Cutthroat Trout; measures to prevent deleterious substances, sediment, and invasive species from entering the watercourse; measures to minimize disturbance to aquatic habitats and riparian vegetation; and, a monitoring plan detailing the implementation and effectiveness of the mitigation measures. If implemented as described, the uncertainty for the proposed mitigation measures is low. c) Effects on survival and recovery: Working within fall Restricted Activity Period (RAP): It has been determined by Alberta Environment and Parks that the presence of Westslope Cutthroat Trout or fall spawning species within the proposed work areas is unlikely, and therefore permitting works to occur within the first two weeks of the fall RAP poses little risk to species at risk or other fish species. Incidental death or harm: An experienced fisheries biologist that has experience with Westslope Cutthroat Trout will lead/supervise all fish rescues, and therefore the risk of causing harm to Westslope Cutthroat Trout through fish rescue is low. Habitat alteration: The sites have been selected and designed to enhance existing fish habitat for Westslope Cutthroat Trout in Allison Creek. Therefore, it has been determined that the works pose little risk to species at risk and other fish species.
