Volume 5C, ESA - Trans Mountain Pipeline ULC Environmental Technical Reports Trans Mountain Expansion Project Fisheries (Alberta) Technical Report 4.0 RESULTS OF LITERATURE REVIEW The background information presented in the following sections forms the basis for the field studies and several aspects of the determination of fish and fish habitat sensitivity (as described in Section 3.7). 4.1 General Information Geography, climate, land uses and fisheries resources vary considerably throughout the Edmonton to Hinton Segment. A general overview of fish species of management concern and RAPs relative to the Project area are also presented in Sections 4.1.2 and 4.1.3. Details about the environmental setting, background information and existing land uses, proposed crossings and corresponding fish distributions for each watershed are presented in Section 4.2. Section 4.3 provides details concerning the information and distribution of selected indicator fish species and Section 4.4 provides details concerning other fish species of management concern occurring with the watersheds defined for the Edmonton to Hinton Segment’s Fish and Fish Habitat RSA. 4.1.1 Background The Edmonton to Hinton Segment is located on both Crown and privately-owned lands (i.e., Green and White Areas, respectively) administered by the AESRD Lands Division and encompasses the Edmonton Capital Region. The proposed pipeline corridor lies within AESRD’s Fish Management Zone 2, Parkland Prairies (PP) Watershed Unit PP2 and Zone 1, Eastern Slopes (ES) Watershed Unit ES3 (ASRD 2009). The proposed pipeline corridor crosses the Athabasca Ranch Public Land Use Zone, administered by the Forests Act, Forest Recreational Regulation (AESRD 2012d). From east to west, the Edmonton to Hinton Segment crosses Strathcona, Parkland and Yellowhead counties (Table 4.1).

The Sturgeon River Watershed falls in both of the aforementioned Fish Management zones. The Water Survey of Canada maintains several hydrological stations year-round on some of the watercourses crossed by the proposed pipeline corridor. A summary of historic hydrometric data from the hydrological stations near the proposed pipeline corridor is provided in Table 4.2. All of the hydrographs considered for the Edmonton to Hinton Segment show similar seasonal flow patterns which indicate annual high flow events coincide with snowmelt. Flows are lowest during the winter months from October through March and discharge begins to increase during the spring in April. Peak flows vary depending on the size and location of the watercourse, but the North Saskatchewan River reaches peak flow in July, while the smaller rivers and creeks reach peak flow from April to June. Flows begin to decline in July and continue to decline until October, just prior to freeze-up. Graphical representation of discharge data from these monitoring stations is provided in Appendix B.

However, two fish species listed by COSEWIC, lake sturgeon and bull trout, are known to occur in the North Saskatchewan River Basin in the vicinity of the proposed pipeline corridor (COSEWIC 2013). Since 2006, the Saskatchewan River populations of lake sturgeon have been listed by COSEWIC as Endangered. The Endangered listing indicates that this population is “facing imminent extirpation or extinction” (COSEWIC 2013). The Saskatchewan River populations of bull trout have recently been listed as Threatened by COSEWIC, while Western Arctic drainage populations (which includes the Athabasca River Basin) have been listed as Special Concern (COSEWIC 2013). Provincially, the general status of lake sturgeon has been recently downgraded from At Risk to its current listing of Undetermined (ASRD 2010a); however, Alberta’s ESCC has designated lake sturgeon as a Threatened species (AESRD 2012b). Provincially, Arctic grayling and bull trout have a general status listing as a Sensitive species (ASRD 2010a), but according to the ESCC are Species of Special Concern 7894/December 2013 REP-NEB-TERA-00005 Page 4-2 Volume 5C, ESA - Trans Mountain Pipeline ULC Environmental Technical Reports Trans Mountain Expansion Project Fisheries (Alberta) Technical Report (AESRD 2012b). Sauger and northern redbelly dace are also listed (general status) as Sensitive in Alberta (ASRD 2010a) and are known to occur in the North Saskatchewan and Athabasca River basins near the proposed pipeline corridor. In addition, rainbow trout (Athabasca River population) and spoonhead sculpin are listed (general status) as At Risk and May be at Risk in Alberta, respectively. Athabasca rainbow trout are also listed by the ESCC as In Process (AESRD 2012b). Table 3.1 provides all of the definitions of the general status listings as identified in the general status of Alberta Wild Species. Table 4.3 presents the status of all the species of management concern previously documented within watercourses crossed by the proposed pipeline corridor. In addition to listed fish species (as defined in Section 3.2.6), other species of management concern are also documented within the Fish and Fish Habitat RSA. Several species with secure designations are documented at proposed crossings within the pipeline corridor including: brook trout; brown trout; rainbow trout (introduced populations); cutthroat trout; mountain whitefish; yellow perch; mooneye: and goldeye.
