COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Rainbow Trout (Oncorhynchus mykiss) in Canada (2015-02-23)

    Rainbow Trout (Oncorhynchus mykiss) is a species of salmonid that is characterized by a silver body covered in black spots with a pink horizontal band. In Canada, Rainbow Trout is native primarily to the western drainages of the continent. There are only three drainages east of the continental divide known to contain native populations of Rainbow Trout: Peace, Liard and Athabasca drainages, and Rainbow Trout (Athabasca River populations) (herein Athabasca Rainbow Trout) is the focus of this report. Athabasca Rainbow Trout are not considered a distinct subspecies, but qualify as a single designatable unit.

  • Recovery Strategy for the Rainbow Trout (Oncorhynchus mykiss) in Canada (Athabasca River populations) (2020-09-10)

    Rainbow Trout (Oncorhynchus mykiss) is a species of salmonid that is characterized by a silver body covered in black spots with a pink horizontal band. Rainbow Trout is native primarily to northeastern Siberia and western North America. In Canada there are only three drainages east of the continental divide known to contain native populations of Rainbow Trout: Peace, Liard and Athabasca rivers. The Athabasca River populations (herein Athabasca Rainbow Trout) are not considered a distinct subspecies, but qualify as a single designatable unit (COSEWIC 2014).

Orders

  • Exemption Order for Certain Licences, Authorizations and Documents (Rainbow Trout (Athabasca River Populations)) (2019-08-21)

    Her Excellency the Governor General in Council, on the recommendation of the Minister of Fisheries and Oceans and the Minister of the Environment, pursuant to section 76 of the Species at Risk Act, makes the annexed Exemption Order for Certain Licences, Authorizations and Documents (Rainbow Trout (Athabasca River populations)).
  • Order Amending Schedule 1 to the Species at Risk Act (Volume 153, Number 17, 2019) (2019-08-21)

    Biodiversity is rapidly declining at all scales, from local to global, as a result of a variety of human activities that increase the rates of species extinction. Current extinction rates are estimated to be between 1 000 and 10 000 times higher than the natural background rate. Higher species diversity positively supports healthy and productive ecosystems that are more resilient to disturbances, and, given the interdependency of species, a loss of biodiversity can lead to a declining resilience of ecosystem functions and services (e.g. natural processes such as pest control, pollination, coastal wave attenuation, pharmaceutical products, temperature regulation and carbon fixing). These services are vital to the health of all Canadians and are important for Canada’s economic well-being. Biodiversity loss can therefore result in adverse, irreversible and broad-ranging effects on Canadians.

COSEWIC Annual Reports

  • COSEWIC Annual Report - 2013-2014 (2014-10-15)

    Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to "assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species". COSEWIC held two Wildlife Species Assessment Meetings in this reporting year (October, 2013 to September, 2014) from November 24 to November 29, 2013 and from April 27 to May 2, 2014. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 56 wildlife species. The wildlife species assessment results for the 2012-2013 reporting period include the following: Extinct: 0 Extirpated: 0 Endangered: 23 Threatened: 12 Special Concern: 20 Data Deficient: 0 Not at Risk: 1 Total: 56 Of the 56 wildlife species examined, COSEWIC reviewed the classification of 40 that had been previously assessed. The review of classification for 25 of those wildlife species resulted in a confirmation of the same status as the previous assessment.

    Offsetting measures will be undertaken at an unnamed tributary to Fox Creek between the Hamlet of Grand Cache and the Town of Hinton, and will include the replacement of an existing structural plate corrugated steel pipe culvert with a new three-span bridge on a concrete substructure, channel realignment, and habitat enhancements. The unnamed tributary to Fox Creek is known to contain Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) (Rainbow Trout from this point forward). A fish rescue and relocation will take place before in-water construction activities begin. The proposed authorized project which necessitated the previously described offsetting involves construction of a new bridge to replace the existing bridge across the Athabasca River at Highway 813 near the Town of Athabasca, Alberta. The new bridge will be approximately 279 m long with two 3.7 m wide lanes of traffic, and a 2.5 m wide sidewalk on the south side of the structure. The bridge design is a three-span steel girder, with two instream piers and abutments located above the high water mark. Temporary isolation ring berms will be constructed from non-dispersive material to install the instream piers. Riprap armouring will be placed along the bank of the river opposite each ring berm to prevent erosion due to increased velocities generated by the channel restrictions associated with the temporary berms, and to enhance bank stability. Construction of the replacement bridge structure is expected to begin in early 2020, with completion anticipated in the fall of 2022. Demolition of the existing bridge is anticipated to be completed using an ice bridge during the winter of 2022 and 2023 and is not expected to require the construction of berms.

    Five kilometres of Apetowun Creek and its upper watershed are being rehabilitated after it was destroyed by a coal tailings release that originated at the Obed Mountain Mine near Hinton, Alberta, in October of 2013. There are several components to the overall project. Specific to species at risk, and as an offset for rehabilitation works authorized under file 18-HCAA-00236, a population of Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) will be established above a fish barrier in the rehabilitated sections of Apetowun Creek. Rainbow Trout (RNTR) of unconfirmed genetic makeup will be tagged with Passive Integrated Transponders (PIT), and a caudal fin clip will be collected for genetic testing. RNTR will then be released into natural holding areas while genetics are assessed. Once rehabilitation efforts have been completed in 2019/20, RNTR that are confirmed pure-strain Athabasca River population RNTR will be re-located to upper-Apetowun Creek, upstream of a constructed fish passage barrier. The barrier will be constructed at the downstream end of APC-7 to prevent upstream movement of fishes. All other fish species will be released below the fish passage barrier. Migrant, or, resident Bull Trout (Salvelinus confluentus) (Saskatchewan - Nelson Rivers populations) from the Athabasca River may be captured during fish rescues. These fish will be released downstream of the barrier. Fish inventory programs conducted in Apetowun Creek from 2014 to 2018 indicate Bull Trout presence is limited to a few individuals near the confluence of Plante and Apetowun creeks, approximately 15 km downstream of the upper-Apetowun rehabilitation site, and are unlikely to occur in or near the rehabilitation site. Any that are captured will be enumerated, weighed, and measured for length before being released downstream of the barrier. The rehabilitation project consists of construction activities that require de-watering of approximately 5 km of Apetowun Creek and its upper-watershed, including reaches one to seven and its tributaries. This work will require multiple fish rescues and relocations to remove fishes from the proposed instream restoration areas in upper-Apetowun Creek.

    Westmoreland Coal Company (WCC) is planning to expand their current operations at the existing Coal Valley Mine in west-central Alberta south of the Town of Edson. The Robb Trend expansion was initially proposed by the previous owner of the Coal Valley mine, and is again being explored by the new owner, Westmoreland. An environmental impact assessment (EIA) was completed in 2012, but the project did not proceed. The EIA that was prepared included a comprehensive assessment of fisheries resources within the watersheds that may be subject to impact if the expansion was to proceed. Provincial regulators have requested that WCC undertake additional fisheries investigations to supplement the existing data set and to verify if conditions have changed since the EIA was conducted. Proposed fisheries investigations include sampling with a backpack electrofisher, accompanied by a fish habitat inventory at sample sites that were established for the original EIA. Electrofishing will consist of single-pass surveys of 300 to 500 m long sample sections, dependant on watercourse size. Based on available information, and the portion of the province in which sampling will be conducted, it is anticipated that Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) will be encountered during the investigations.

    The proposed works involve Coal Valley, Mercoal West Development and the required diversion of a Mercoal Creek Tributary #3 (MET3) to facilitate mining. Following coal extraction, Coal Valley was required, as per Authorization No. ED-09-2664A, to reconstruct the stream, construct fish habitat features in the restored channel, and monitor the channel and constructed habitat following construction to ensure specifications in the authorization have been met. The monitoring requires a five-year monitoring plan with a final report to Fisheries and Oceans Canada by December 1, 2020, that includes four-season monitoring of the fish community. Monitoring will utilize electrofishing, minnow traps, egg sampling, and underwater cameras and will include seasonal assessment of fish habitat conditions and establishment of reference transects to monitor depth, velocities and substrate composition as well as photo documentation of habitat conditions. This work will provide data that will help with future management decisions, ensure that fishes are utilizing the constructed channel and habitat, and that Coal Valley is meeting their regulatory commitments. The current sampling is for the fall component of the four-season sampling program to document the fish presence and abundance using electrofishing and assessment of habitat conditions. This activity may result in incidental harm, harassment, or death of Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations), a listed aquatic species at risk, resulting from capture and release during sampling.

    The proposed works involve Coal Valley, Mercoal West Development and the construction of a haul road, which required a Fisheries Act authorization (Fisheries and Oceans Canada [DFO] File No. ED-09-2664A). The crossing included a 64 m by 3 m diameter culvert embedded into the streambed of a tributary to Mercoal Creek (MET2), with a constructed artificial channel joining the culvert extending 23 m upstream and 30 m downstream of the culvert. Following construction of the stream and haul road, Coal Valley was required as per Authorization No. ED-09-2664A to monitor the channel and constructed habitat to ensure specifications in the authorization have been met. The monitoring requires a five-year monitoring plan that includes four-season monitoring of the fish community, utilizing electrofishing, minnow traps, seasonal assessment of fish habitat conditions, and photo documentation of habitat conditions. Monitoring reports are submitted to DFO by December 1 of each year. This work will provide data that will help with future management decisions, ensure that fishes are utilizing the constructed channel and habitat, and that Coal Valley is meeting their regulatory commitments. The current sampling is for the fall component of the four-season sampling program to document fish presence and abundance using electrofishing and assessment of habitat conditions. This activity may result in the incidental harm, harassment or death of Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations), a listed aquatic species at risk, resulting from capture and release during sampling.

    The proposed works involve baseline data collection and fish inventory for Coal Spur Vista Mine's proposed expansion. The fish inventory will help to characterize fish presence and distribution, providing information regarding the fisheries resources within the proposed expansion area. Characterization includes determining the presence and distribution of Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) as a component of the overall fish community in the drainage, and an evaluation of fish habitat potential and suitability within the reaches to guide further inventory work. The inventory is a four-season program utilizing electrofishing as a primary sampling method, gee-type minnow traps as a secondary method, and the possibility of eDNA collection when it is expected that migrating fall spawning salmonids have occupied suitable reaches for spawning. The current sampling is for the fall component of a four-season sampling program to document fish presence and abundance using electrofishing and assessment of habitat conditions. This activity may result in incidental harm, harassment, or death of Rainbow Trout, a listed aquatic species at risk, resulting from the capture and release during sampling.

    TC Energy has proposed to expand the existing NOVA Gas Transmission Ltd. natural gas transport system. The proposed project will involve the installation of around 350 km of nominal pipe size 48 piping. In order to support regulatory applications for the project, the applicant is proposing to collect baseline fish and fish habitat information at the proposed watercourse crossings. Habitat assessments from 2018 identified 20 potential first-order streams, and baseline surveys identified nine watercourses within the home range of Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) and Bull Trout (Salvelinus confluentus) (Saskatchewan - Nelson Rivers populations). Proposed activities include habitat surveys, and, if necessary, spawning surveys to observe staging/spawning fishes. If the habitat looks conducive to staging/spawning, but no fishes are observed, sampling surveys will be conducted using the single pass method of backpack electrofishing. If electrofishing cannot be undertaken safely and effectively, minnow traps will be used; however, this is unlikely to occur, due to inadequate depth. All captured fishes will be identified and measured before being released, alive and unharmed, in the same location as capture. This activity may result in the incidental harm, harassment, or death of the previously described populations of Rainbow Trout and/or Bull Trout, listed aquatic species at risk, resulting from capture and release during sampling.

    The activity is being undertaken to replace a culvert carrying an unnamed tributary of the MacLeod River (hereafter referred to as The Tributary) under Pembina River Road, nearest to Mercoal, Alberta. In 2018, a washout occurred on Pembina River Road and crushed a portion of the culvert on the outlet side of the crossing. The existing culvert will be removed and replaced with a new corrugated steel pipe culvert. Reconstruction and sloping of the bank will be required where the road washout has resulted in a loss of road base material. The proposed activities consist of: Installing erosion and sediment control measures and preparing the site, installing sheet pile coffer dams upstream and downstream of the existing culvert, performing a fish rescue within the isolated areas and dewatering using pumps, removing the existing culvert and replacing it with the new culvert, placing riprap aprons and armouring at the culvert inlet and outlet, and removing the coffer dams to allow water to flow through the new culvert. These activities could result in harm, harassment, capture, and incidental death of Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) (Rainbow Trout from this point forward), a listed aquatic species at risk, resulting from dip netting or electrofishing activities and handling.

    The goal of this work is to remove a crossing that is acting as a barrier to fish passage, and undertake remedial action to prevent the continued sedimentation of Plante Creek, for which this crossing is acting as a point source. By conducting this work, the connections between isolated habitats for Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) and Bull Trout (Salvelinus confluentus) (Saskachewan - Nelson Rivers populations), species listed under the Species at Risk Act (SARA), will be restored, and the habitat in which they can reside will no longer continue to deteriorate. The works will entail the removal of two 1100 m diameter, 25 m long corrugated steel pipe hanging culverts from an oil and gas resource road, followed by the installation of a single span 30 m bridge, the restoration of the creek bed, and river banks. Prior to works commencing, the worksite will undergo a fishery isolation (75 m2), involving the installation of fish fences, the removal and upstream transport of fishes from the isolated reach, de-watering of the worksite, and installation of a pump-around system to maintain 100% of downstream flow. Corralling and dip netting of fishes will be used preferentially over trapping and electrofishing, wherever possible, to minimize harm to fishes. The work on this crossing is being conducted as part of a maintenance and upgrade project for Eccles Road, to improve the safety and integrity of the road. Tourmaline Oil Corp. hired Woodlands North to conduct an inventory on its roadway watercourse crossings and to make recommendations for which watercourse crossings were necessary to remediate to meet the requirements set out by the Roadway Watercourse Crossings Directive set by Alberta Environment and Parks. Woodlands North recommended the remediation of this crossing to permit fish passage throughout Plante Creek.

    The objective of the activity is to conduct fish salvages near Hinton, Alberta, for the isolation and trench installation of the proposed pipeline related to the twinning of an existing 1,150 km pipeline between Strathcona County, Alberta, and Burnaby, BC. The proposed isolated area will be dewatered, with flow maintained with bypass pumps. Prior to and during dewatering, a fish rescue will be completed using fish traps, backpack electrofisher, and dip nets. Fishes captured from the isolated area will monitored during relocation and released into previously identified habitats that provide slack water, cover, and suitable water quality conditions. Fisheries and Oceans Canada understands that the fish rescue will be conducted at pipeline crossing AB-137 KP 244 on Little Sundance Creek, Alberta. Based on available distribution information, it is anticipated that Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) may be encountered during the fish rescue activities.

    The proponent is proposing fish salvages at six watercourse crossings on Lynx Creek and other unnamed tributaries of Lynx Creek in relation to the McLeod River North natural gas pipeline that has been reviewed and approved by the National Energy Board/Canada Energy Regulator (NEB/CER). The project was reviewed and approved by NEB/CER before Rainbow Trout (Oncorhynchus mykiss) (Athabasca River populations) (Rainbow Trout from this point forward) was listed under the Species at Risk Act, and the project now requires a permit to conduct fish salvages, as distribution mapping indicates Rainbow Trout may be present at all work sites, and historical fish capture data indicate that Rainbow Trout is present in Lynx Creek. Fish captures and relocations are expected to occur in February, 2020. Watercourse crossings will use trenched methods (isolated if water is present, and open-cut if dry or frozen to bottom). During the isolation, downstream flow will be maintained at all times using by-pass pumps. The water and pump intakes will be screened in accordance with the Fisheries and Oceans Canada's Freshwater Intake End-of-Pipe Fish Screen Guidelines. Capture methods may involve backpack electrofishing, Gee minnow traps, seine netting, dip-netting, or a combination thereof. These activities will involve incidental capture of Rainbow Trout during site isolation, dewatering, and fish relocation operations.
