Environmental Baseline Study: Fish and Aquatic Resources Section 1: Introduction

1 Introduction

1.1 Background

TOTAL E&P Canada Ltd. (TOTAL) owns a parcel of land in Alberta’s Industrial Heartland near Fort Saskatchewan, Alberta (see Figure 1.1-1). The parcel is situated in the following portions of Township 55, Range 21, West of the 4th Meridian: • Section 18: • portions of legal subdivisions (LSDs) 11, 12 • all of LSDs 13 and 14 • Section 19 • Section 20: • portion of LSD 3 • all of LSDs 4, 5 and 6 • northwest quarter Throughout this document, this land (including small inholdings that TOTAL is intending to acquire) is referred to as the TOTAL lands. This report is one of a series of studies prepared to document the environmental baseline conditions of the TOTAL lands and surrounding area.

1.2 Focus of Baseline Investigations

The objective of the fish and aquatic resources baseline study was to characterize the aquatic communities and aquatic habitats of the watercourses and waterbodies located in the vicinity of the TOTAL lands. The following sections describe current baseline conditions for fish communities, habitat suitability and habitat area for watercourses and waterbodies in the vicinity of the TOTAL lands. Aquatic benthic invertebrate communities, which are a component of fish habitat and a biological indicator of water quality, were surveyed during fall 2007 and will be reported in a separate addendum.

1.3 Study Areas

1.3.1 Local Study Area

The local study area (LSA) for the fish and aquatic resources baseline report (see Figure 1.3-1), includes all TOTAL lands, downstream watercourses that convey site drainage to the North Saskatchewan River and the reach of the North Saskatchewan River adjacent to the TOTAL lands.

There are no lakes in the LSA and ponded water is limited to ephemeral wetlands in low-lying areas. More specifically, the aquatic resources LSA includes: • local watercourses or surface runoff that drain to Astotin Creek, and the reaches of Astotin and Beaverhill creeks that convey natural site drainage to the North Saskatchewan River • the reach of the North Saskatchewan River and tributary confluences between the Sturgeon River and the Redwater River

1.3.2 Regional Study Area

For the regional study area (RSA) for the aquatics environmental baseline study, see Figure 1.3-2. The downstream limit of the RSA is the Elk Point Bridge (Highway 41), which is the location of a reach break specified by the North Saskatchewan River Instream Flow Needs Scoping Study (NSWA 2006). The upstream limit of the RSA is the Town of Devon, which is approximately the existing limit of urban development upstream of Edmonton.

Environmental Baseline Study: Fish and Aquatic Resources Section 2: Methods

2 Methods

2.1 Historical Data

Sources of information for the aquatics environmental baseline study included a review of Alberta Sustainable Resource Development reports and Fisheries Management Information System (FMIS) data, and other publicly available consultant reports, scientific literature and discussions with regional fisheries biologists at Alberta Sustainable Resource Development.

2.2 Data Collection

The North Saskatchewan River was systematically sampled to provide sufficient data to describe the local summer-season fish communities, to cover all habitat units present in the LSA and to provide descriptive biophysical data. For the fish and aquatic resources sampling locations for the aquatics environmental baseline study, see Figure 2.2-1. The sample locations for the environmental baseline study were selected to include representative riverine and stream aquatic habitats near the TOTAL lands. Two locations were assessed on Astotin Creek during the period August 1 to 3, 2007: one downstream of the TOTAL lands (AC-1) and the second, a reference location, approximately 18 km upstream from the lower site (AC-2).

2.2.1 Habitat Assessment

Fish and fish habitat field data for the environmental baseline study were collected on the North Saskatchewan River between July 26 and August 7, 2007. Fish habitat assessments for Astotin Creek were completed on August 1 and 3, 2007. Fish habitat was assessed and described at each site in the North Saskatchewan River and Astotin Creek. Instream habitat was classified in distinct habitat units and cover types (see Appendix A) and adapted from systems developed and used in Alberta streams and rivers (O’Neil and Hildebrand 1986; RL&L 2001). Parameters collected at each tributary site included channel width, substrate composition, general riparian vegetation and availability of instream cover. North Saskatchewan River habitats, because of their increased size, were generally assessed based on broad instream cover features (RL&L 2001) and bank–riparian features. The bank habitat classification was based on the system used in RL&L (1994a; see Appendix A). The data collected were subsequently pooled and summarized to provide a qualitative characterization of aquatic habitat in the entire surveyed section. Supplementary bathymetric information was collected using a Garmin 298 GPS Sounder on the North Saskatchewan River, adjacent to, and downstream of the TOTAL lands. Basic water quality (conductivity, turbidity, pH and temperature) was determined at all sample locations. Conductivity, pH and temperature were measured using a Horiba W-2000S water quality monitor. Dissolved oxygen (DO) profiles were measured at three locations using an Oxyguard Beta meter. Shoreline and riparian habitat features at sampling locations were also documented by digital photographs, including upstream and downstream views of the surveyed sections.

2.2.2 Fish Community Sampling

2.2.2.1 Field Collection Methods

Fish capture techniques used in the LSA included boat electroshocking, backpack electrofishing, beach seining, set lining and minnow trapping. Boat electroshocking was done along nearshore transects in the North Saskatchewan River from a 4.6-m aluminum jet drive boat, specifically modified for electrofishing. A Smith Root Type VI-A electrofisher, powered by a 4500-W generator, provided input voltage to two 3.5-m-long booms. Each boom supported trailing anode arrays conducting electrical current into the water. Voltages were generally set between 336 and 504 VDC, producing 4 to 6 A output. Immobilized fish were collected with dip nets and placed in an onboard holding tank. Fish were processed at the end of each sampling section and released unharmed. Fish sampling at Astotin Creek reference sites AC-1 and AC-2 and in selected shallow-water habitats on the North Saskatchewan River was done using a Smith-Root Type XII high-output backpack electrofisher. The electrofisher settings included voltage (500 VDC), pulse rate (30 Hz) and pulse width (4 to 6 ms). The electrofisher operator waded upstream along the banks and sampled in the immediate vicinity of suspected fish-holding sites (e.g., overhanging branches, undercut banks, submerged logs and boulders). The netter, positioned immediately downstream, collected the temporarily immobilized fish and placed them in a handheld container filled with water. Setlines were deployed for an overnight period in suitable deepwater locations on the North Saskatchewan River. Each setline consisted of a 40-m mainline and eight barbless “J” hooks, attached at intervals of approximately 4 m using swivel snaps. The hooks were baited with a combination of smelts, leeches and minnows. Minnow traps (Gee traps) were used in shallow-water, low-velocity locations and beach seining was done in suitable shallow-water habitats using a 3.3-m seine (4.8-mm mesh size).

2.2.2.2 Sampling Strategy

Sampling was stratified to include an equivalent amount of effort between four river sections in the LSA (see Figure 2.2-1). Within the upper section (Section 1) located adjacent to the TOTAL lands, boat electrofishing was completed over an approximately 3 km reach on the right downstream bank and a 1 km reach on the left downstream bank. Two additional downstream sections were sampled in this configuration (Sections 2 and 3). Boat electrofishing was also done at 1-km intervals downstream of any other identified industrial facility in the LSA (Section 4). Minnow trap and setline effort was also applied equally between sections. Backpack electrofishing and beach seine effort were applied opportunistically where shallow habitat conditions were suitable for these techniques to be applied.

Environmental Baseline Study: Fish and Aquatic Resources Section 2: Methods

2.2.2.3 Data Analysis

During all fish sampling, pertinent data were recorded on Fish Sample Record Forms or in field notebooks. Data included fish captured–observed, sampling time, GPS waypoint locations and life history information. Captured fish were identified to species, measured (fork length in mm), weighed (g) and then released.

2.2.2.4 Fish Health

A sample of large-bodied fish (i.e., adult sportfish and sucker species) was examined for external deformities, erosion, lesions and tumours (DELTs), and information recorded on their condition.

2.3 Quality Assurance and Quality Control

The aquatic resources historical baseline data were obtained from government sources, including Alberta Sustainable Resource Development, Environment Canada and Alberta Environment, which are subject to the internal QA/QC procedures of those agencies. Field data were collected according to specific work instructions from the Discipline Lead. Data entry was subject to peer review for data-entry errors. Data analysis and associated calculations were also reviewed by senior staff.

3.1 North Saskatchewan River

3.1.1 Background

The historical status of fish populations in the North Saskatchewan River in the vicinity of Edmonton has been documented in records from early settlement of the area by the Hudson Bay Company (Johnson 1967) to more recent published reports and documents by a number of researchers (Paterson 1966; Nelson and Paetz 1992; Roberts 1974, 1980; Munson 1978; Allan 1984; RL&L 1980, 1989, 1991a, 1992, 1993, 1994b, 1998, 1999, 2001 and Sentar 1996). During the past three decades, several studies of North Saskatchewan River fish populations describing fish species distribution, movements, habitats and resource use were focused in the immediate vicinity of the Fort Saskatchewan industrial area, including portions of the present LSA. As part of the EIAs for the Dow Chemical development, RL&L (1986, 1989) described fish and fish habitat features in this portion of the river. Aquatic biological resources (fish and benthic invertebrates) were sampled in the same area for the subsequent Dow Chemical environmental monitoring program (RL&L 1991a). Fish sampling was also done in the North Saskatchewan River in 1991, from upstream of the ESSO Agricultural Chemicals Complex to downstream of the Highway 38 (Vinca) Bridge during studies for the proposed OSLO Upgrader development (RL&L 1991b). The North Saskatchewan River and tributary streams between Fort Saskatchewan and Redwater have recently been studied to develop baseline information for EIA requirements of proposed new upgrader developments and infrastructure, including Northern Lights Partnership (Northern Lights 2006), BA Energy (2004), North West Upgrading (North West 2006), Fort Hills (2006) and Shell Canada (Shell 2005, 2007). Several other studies have been completed for site-specific regulatory requirements, such as water intake assessments and monitoring (Golder 2003, 2004). Data from these surveys and current collection records (FMIS 2006) indicate that 17 fish species commonly inhabit the North Saskatchewan River in or near the LSA. An additional 13 species might occur in the RSA (i.e., upstream–downstream reaches and tributaries) but are rarely found in the LSA. For the fish species expected to occur in this portion of the North Saskatchewan River and their relative abundance (common, occasional or rare), see Table 3.1-1.

3.1.2 Habitat Description

3.1.2.1 Instream Habitat

The North Saskatchewan River in the LSA is predominantly single-channelled, and exhibits an irregular meander pattern (see Figure 3.1-1). The river is entrenched and laterally stable, with a defined thalweg. In the survey area, the instream habitat is characterized mainly by deep Run habitat (R1; average depth greater than 1.25 m). Some small Backwater Pools and isolated Riffle (RF) habitats are present. These were often associated with small islands and exposed bars and shoals. A short section of shallow Run (R3) and Riffle (RF) habitat was identified at the downstream end of Section 3. The dominant instream cover in the river was provided by depth and water turbidity; boulder and cobble substrates also provided occasional cover. In general, the substrate was dominated by sand and silt but discrete areas of cobble and large boulders were observed throughout the area. Underwater observation of the substrate using digital imaging sonar (DIDSON) near Section 1 showed cobble and boulder substrate within 30 m of the shore (Golder 2007). Several deep areas were identified during the aquatics field program; a maximum depth of 5.2 m was recorded in Section 1. Under some seasonal flow conditions and reduced velocities associated with backwaters, these areas could form defined Pool (P1 and P2) habitats. These are important fish habitat features, providing deepwater cover and holding, feeding and overwintering functions.

3.1.2.2 Bank Habitat

The bank habitat type in the North Saskatchewan River LSA was described and mapped on August 7, 2007 (see Figure 3.1-1). Bank habitat was assessed at the water–shoreline interface. As such, bank habitat can change depending on the river stage or water elevation at the time of the assessment. In the surveyed section of the North Saskatchewan River, armoured, depositional and erosional bank habitats were observed. Approximately 65% of the banks assessed were erosional (see Appendix B, Table B-1). Depositional (31.6%), armoured (2.5%) and composite (E3/A2, 0.9%) bank habitats made up the remainder. E3 bank habitat was most common, accounting for over 28% of the total bank assessed. This habitat type typically has high, steep, eroding banks, loose till deposits and moderate to high offshore velocity and depth. Cover is usually limited to instream substrate roughness and turbidity. The armoured A4 bank habitat identified was associated with the Shell Scotford water intake structure on the right downstream bank of the North Saskatchewan River. Armoured bank habitat was not present along the left downstream bank.

3.1.2.3 Flows and Water Quality

During the study period, the discharge of the North Saskatchewan River ranged between 155.2 m3/s (August 7, 2007) and 336.7 m3/s (July 29, 2007). The North Saskatchewan River is subject to flow regulation from upstream hydroelectric generating facilities. As a result of load peaking from energy demands, the river experiences daily water level fluctuations (see Figure 3.1-2).

Figure 3.1-2 Hourly Discharge Data for the North Saskatchewan River at Edmonton SOURCE: RNSASEDM Unpub. data; Alberta Environment, Water Sciences Branch. NOTE: The highlighted sections of the curve indicate field sampling periods during the baseline study.

During the field program (July 27 to August 7), daily water level fluctuated between 0.21 and 0.67 m and fluctuated an average of 0.46 m (see Appendix B, Table B-2). Daily river fluctuations likely affect the use, productivity and habitat values of the nearshore and shallow habitats.

The average water temperature of the North Saskatchewan River along the water quality transect on August 2 was 22.1°C (see Appendix B, Table B-3). Mean conductivity at this location was 147 µS/cm and pH was 8.48. Turbidity was similar at all sample locations and averaged 14.2 NTU. DO and water temperature profiles were measured in three locations that correspond to the deepest part of the channel in the three sections. DO and water temperatures were similar throughout the water column and among stations (see Appendix B, Table B-4).

3.1.3.2 Relative Abundance

For a summary of total numbers of fish captured or observed in the mainstem North Saskatchewan River and percentage composition of catch, see Table 3.1-3 and Table 3.1-4.

Approximately 17.9 km of the North Saskatchewan River was sampled for fish by boat electroshocking (252.3 minutes effort; Appendix C, Table C-2) in the LSA. A total of 274 fish were captured or observed and included seven sportfish and eight non-sportfish species. Most of the sportfish catch consisted of goldeye (n=33), but mooneye (n=20), walleye (n=13), northern pike (n=5), sauger (n=5), lake sturgeon (n=2) and burbot (n=1) were also present in the sportfish catch.

Non-sportfish were considerably more abundant than sportfish (n=195) in the boat electrofishing catch. White sucker was the most abundant member of this group, accounting for 46.5% of the non-sportfish species catch (see Table 3.1-4). Shorthead redhorse and longnose sucker were also abundant in the LSA, contributing 23.7% and 20.7%, respectively. Silver redhorse (n=3), considered rare in this stretch of the North Saskatchewan River, and quillback (n=3) were also present. The remainder of the non-sportfish composition included longnose dace (n=3), spoonhead sculpin (n=1) and emerald shiner (n=1). Backpack electrofishing was conducted at three shallow shore margin sites in the North Saskatchewan River mainstem for a combined effort of 1146 s (Appendix C, Table C-3). A total of 127 fish were captured or observed, consisting of longnose dace (n=113), young-of-the-year white sucker (n=13) and a juvenile burbot (n=1). Minnow trapping was done at six sites. A combined sampling effort of 87.2 h resulted in the capture of one longnose dace and four crayfish (invertebrates) (see Appendix C, Table C-4). Setlines were deployed at six locations in the North Saskatchewan River mainstem in areas of laminar flow associated with increased depth (greater than 3 m). A total of 792.2 hook-hours of setline effort were expended; no fish were captured with this method (see Appendix C, Table C-5). Beach seine hauls in the LSA encompassed 685 m² of sampled habitat. The catch consisted of one longnose sucker, one white sucker and one unidentified juvenile sucker.

3.1.3.3 Distribution and Habitat Use in the Local Study Area

Fish distribution and habitat use were assessed based on the electrofishing catch, as this method was used in all sections. For combined numbers and catch-per-unit-effort (CPUE) values for sportfish and non-sportfish collected by boat electrofishing over the study area, see Table 3.1-4 and Appendix C, Table C-2. The CPUE values overall were low; however, these values were similar between sections. Species diversity was lower in Section 4, but diversity was similar between sections encompassing Sections 1, 2 and 3. Although some minor differences in distribution of species were noted between sections, these differences can be attributed to the local availability of suitable habitats and cover. Goldeye, mooneye and northern pike were more common in Section 1 than in the other sections, whereas lake sturgeon was encountered only in Sections 2 and 3. Sucker species were relatively common in all sections.

The following general description of habitat use has been largely extracted from data for the proposed Northern Lights Upgrader (Golder 2006a), located on the North Saskatchewan River in the lower portion of the LSA, and is applicable to habitat use for the major species encountered in the present LSA. Use of aquatic habitats in the North Saskatchewan River varies according to fish species requirements, and is dependent on time of year and life history activity (i.e., spawning, feeding or rearing). The mainstem of the North Saskatchewan River provides rearing and feeding habitat for several common sportfish species, including northern pike, walleye and sauger. No descriptions are available of mainstem spawning by northern pike, walleye and sauger; however the capture of young-of-the-year (fry) of these species in 1985 (RL&L 1986), indicates spawning might occur in nearby tributaries such as the Sturgeon River, Redwater River and possibly Beaverhill Creek (RL&L 1991b). Walleye and sauger occur in the mainstem of the North Saskatchewan River in the LSA throughout the year. Adult walleye and sauger will primarily use deeper Pools and Backwater areas for feeding and holding. In the LSA, suitable spawning habitat for walleye and sauger is present in Run habitats with gravel–cobble substrate. Walleye and sauger might also use some tributary systems entering the North Saskatchewan River for spawning, providing the quality of the spawning habitat is sufficient. Based on findings of Patterson and Sullivan (1998), the ages of the walleye sampled from near the Sturgeon River confluence suggest that walleye are possibly using the Sturgeon River for spawning.

Environmental Baseline Study: Fish and Aquatic Resources Section 3: Results

Northern pike occur in the LSA of the North Saskatchewan River throughout the year. Adults will use the slower Backwater or slackwater areas for holding and feeding. Northern pike require vegetation for spawning and might find suitable spawning habitat in vegetated floodplains or along the banks of shallow Backwater areas. A number of the tributary systems entering the North Saskatchewan River, in the LSA and RSA, might provide adequate spawning habitat. Juvenile and young-of-the-year northern pike are likely to favour the rearing habitat and abundant cover provided by instream vegetation in some of the slower-moving tributaries and side channels. Goldeye is one of the dominant sportfish species of the North Saskatchewan River in the RSA. These goldeye are thought to be part of a largely migratory population that migrate upstream from the lower reaches near the Saskatchewan border in early spring to spawn. These fish feed over the summer in areas within the RSA before returning downstream in the fall to overwinter (RL&L 1989), although more recent studies (RL&L 2001) indicate some adult goldeye likely remain in the Edmonton area year-round. Mooneye has a similar life history and adults are expected to reside in this section of river. Mountain whitefish inhabiting the North Saskatchewan River are more common in the upper portion of the RSA and typically occur in higher numbers during the fall than in the spring. The increase in relative abundance in the fall suggests that mountain whitefish might be spawning or overwintering in the Edmonton area (RL&L 1999) and spawning areas have been documented in the RSA in the upper Edmonton area (RL&L 2001). Mountain whitefish require Riffle and Rapid habitats with gravel and cobble substrate for spawning. This species is not common in the LSA, but does occur seasonally in small numbers. Deep Run (R1) habitat in the LSA could provide suitable conditions for adult feeding and holding. Burbot are relatively common throughout the river. An increase in relative abundance during late summer and fall suggests that burbot might be overwintering and possibly spawning in the LSA during mid-winter. This is supported by the presence of concentrations of adult fish observed near Fort Saskatchewan (RL&L 1991a). Adult burbot prefer slow, deep Run habitats, which are common in the LSA. Burbot might use the gravel substrate present throughout the survey area to spawn. Juvenile burbot were captured at two locations during the present study, indicating use of the North Saskatchewan River for rearing. During surveys for the Northern Lights upgrader (Golder 2006a), juvenile burbot were found using the rock spurs and large boulders along the shoreline as rearing habitat. A juvenile burbot was also captured in the Redwater River (Golder 2006a), suggesting that young burbot also likely use the larger tributary systems for rearing. The occurrence of lake sturgeon in this portion of the North Saskatchewan River is considered occasional; however, historical records indicate that lake sturgeon were formerly more abundant in this area (Johnson 1967). Lake sturgeon is known to inhabit the North Saskatchewan River near Fort Saskatchewan (RL&L 1999) and downstream reaches to the Saskatchewan border. The present North Saskatchewan River population in Alberta is likely less than 1400 fish (Watters 1995). Low catch incidences in past surveys are likely due to the fact that lake sturgeon prefer to hold in deep, slow Run and Pool habitats, which are difficult to sample by boat electrofishing. During the present survey, two individuals were captured in shallow water in Sections 2 and 3, where they were suspected to be feeding.

TOTAL E&P Canada Ltd. December 2007 Page 3-9

Environmental Baseline Study: Fish and Aquatic Resources Section 3: Results

The mainstem of the North Saskatchewan River provides year-round habitat for a variety of coarsefish and minnow species. Substantial numbers of white sucker, longnose sucker, shorthead redhorse, longnose dace, lake chub and emerald shiner are present in this section of river. Significant spawning use is evident as a result of the large number of young-of-the-year captured during 1985 (RL&L 1991b) and young-of-the-year fish observed during the present baseline survey. Ripe male shorthead redhorse and spawning white sucker were captured in spring on shoals and shallow gravel riffles in the LSA during the Northern Lights Upgrader fisheries assessment (Golder 2006a).

3.1.3.4 Fish Health

External exams were completed on most large-bodied fish sampled to identify physical abnormalities and DELTs. Most sportfish were observed to be in a generally healthy state, although some abnormalities were detected (see Appendix C, Table C-1). Abnormalities were noticeably more prevalent on white sucker (48.3% of the sample), including lesions on 23.2% of the sample (see Appendix C, Table C-6; Appendix D, Photo 16).

3.1.3.5 Resource Use

Sportfishing occurs throughout the North Saskatchewan River in and downstream of Edmonton (RL&L 1990). Many of the preferred angling locations in the RSA are road access points, bridge locations or tributary confluences accessible by road or foot. However, the presence of a new permanent boat launch facility at Fort Saskatchewan (upstream from the LSA) has expanded access and use of the river for recreational fishing. In the LSA, the primary points of public access for angling are the confluence of the Sturgeon River, the Highway 45 bridge crossing and the Redwater River confluence. Use of the North Saskatchewan River by boaters and shore anglers was recorded on an opportunistic basis, with a low degree of use noted during the short period of the present baseline survey. One angling party of four was observed at the mouth of the Redwater River and another single angler was recorded at the CN trestle (bridge) upstream from the Sturgeon River. Several boats were also observed on the North Saskatchewan River during the survey (see Appendix C, Table C-7). Current information on the level of angling use and catches in the North Saskatchewan River is limited; however some data encompassing the upper portion of the LSA and the RSA upstream to Edmonton are available from an Alberta Conservation Association survey (Patterson and Sullivan 1998), which included the Sturgeon River confluence. This survey was done over a three-month period in 1997, in the City of Edmonton and downstream to the vicinity of Fort Saskatchewan. The total estimated number of anglers was 12,166, with an estimated 24,979 angler/hours of effort. In the LSA, 451 anglers and 1132.5 angler/hours of effort were recorded at the Sturgeon River confluence. Eleven species were observed in the catch, but the most commonly caught or targeted sportfish were goldeye, walleye and pike. The two species that were kept most often were pike and goldeye.

Environmental Baseline Study: Fish and Aquatic Resources Section 3: Results

Walleye sampled during the Alberta Conservation Association study were identified (by size) as likely exceeding the Canadian Health and Welfare mercury limits (0.5 ppm for 400 g of fish/week) for occasional consumption. Consumption advisories for walleye, sauger, northern pike and goldeye are in place for the North Saskatchewan River (ASRD 2007), although a harvest limit of zero walleye is currently in effect for the North Saskatchewan River to help manage the stock, which is considered to be in a collapsed state (ASRD 2007).

3.2 Astotin Creek

3.2.1 Background

Astotin Creek originates from Astotin Lake in Elk Island National Park and flows approximately 42 km before entering Beaverhill Creek (Golder 2006b). The creek flows through agricultural lands, and riparian habitats are influenced by cattle pasturing. In the LSA, Astotin Creek runs parallel to the TOTAL lands along Range Road 214, and receives some limited surface drainage from the property. The FMIS database and recent baseline surveys for proposed developments identified several cursory fisheries studies of Astotin Creek (Shatz et al. 1997; Westworth 1999; Golder 2006b). The reported fish species in Astotin Creek are species generally tolerant of degraded habitat conditions and include brook stickleback, fathead minnow and white sucker. During a recent baseline fish habitat assessment for the proposed Northern Lights upgrader development, only brook stickleback was collected from a site in the upper reaches of Astotin Creek (Golder 2006a).

3.2.2 Habitat Description

3.2.2.1 Site AC-1

Site AC-1 was located in SW-28-55-21-W4 in a field used as cattle pasture (see Appendix D, Photo 9 and Photo 10). A detailed habitat assessment was conducted on approximately 380 m of stream. The mean wetted width in the surveyed area was 5.9 m. Most (92.1%) of the instream habitat in this section consisted of shallow Flat (F3) habitat, with no discernible flow. A 30-m section of deep Pool (P1) habitat was also recorded. Instream cover for fish was provided by aquatic and overhanging vegetation. Dense emergent and submergent aquatic vegetation, consisting of arrowhead (Saittaria cuneata), bulrush (Scirpus sp.), duckweed (Lemna minor) and Potamogeton sp., was abundant throughout the surveyed area. Trace amounts of small woody debris also provided limited cover. The bed and bank substrate in the surveyed area was silt. Stream and riparian habitat has been heavily affected by cattle grazing, and a significant portion of the creek upstream of the site has been channelized and realigned to follow the road allowance. The deep Pool habitat appeared to be used for cattle watering. Conductivity at this location was 544 µS/cm and pH was 7.7 (see Appendix B, Table B-3). Turbidity was moderately high at 240 NTU. Water temperature was 18.5°C and the DO concentration was considered low (2.85 mg/L).

TOTAL E&P Canada Ltd. December 2007 Page 3-11

Environmental Baseline Study: Fish and Aquatic Resources Section 3: Results

3.2.2.2 Site AC-2 (Reference Site)

AC-2 was located in SE31-54-20-W4 (see Appendix D, Photo 11 and Photo 12). A detailed fish habitat assessment of approximately 278 m of stream was done. The mean wetted width in the surveyed area was 2.7 m and measurable flow was present in the creek at this site. The instream habitat diversity was higher than in AC-1 due to the presence of beaver dams. Flat and Impoundment habitats resulting from the beaver dams and large woody debris were most prevalent (59.9% combined), followed by shallow Run (R3) habitat (37.1%). Small falls and chutes created by woody debris were also identified in the surveyed area. Instream cover for fish was provided by aquatic vegetation and woody debris. The riparian area within 3 m of the bank had an open canopy with abundant grasses and few shrubs. Beyond 3 m from the banks, the riparian area was dominated by coniferous forest, which provided a source of large woody debris. Overhanging vegetation, undercut banks, depth and turbidity also provided limited cover. The bed and bank substrate in the surveyed area was predominantly silt, although some large gravel was noted. Conductivity and turbidity at Site AC-2 were considerably lower than observed downstream at AC-1 (see Appendix B, Table B-2). Water temperature (21.2°C) and pH (8.35) were similar to values from AC-1. The DO concentration at this site was 13.09 mg/L, attributable to aeration from flowing water.

3.2.3 Fish Community

3.2.3.1 Species Presence and Composition

3.2.3.2 Site AC-1

According to the results of the FMIS data search and other recent surveys, the lower section of Astotin Creek near the TOTAL lands contains fathead minnow, brook stickleback and white sucker. Sportfish have not been documented. Backpack electrofishing was done along a 200-m section of the creek, for a total effort of 605 s. This sampling resulted in the capture of fathead minnow (n=20) and brook stickleback (n=9). Many more fish were observed, but were difficult to enumerate due to the dense aquatic macrophyte cover. The surveyed section of stream contains limited potential sportfish habitat. Suitable spawning habitat for northern pike was present due to abundant aquatic macrophytes but would only be available if upstream access was possible when water levels are highest or in flood. The numerous beaver dams throughout the length of Astotin Creek, and downstream in Beaverhill Creek, likely restrict the movement of large-bodied fish into this section of stream. The absence of coarse substrate and faster-flowing sections preclude spawning by white sucker, although this species has been documented in other portions of the creek. The surveyed area does provide suitable spawning and rearing habitat for minnow-type species. Overwintering potential was considered to be poor due to low summertime DO measurements; however the deeper Pool habitat likely provides sufficient overwintering habitat for species tolerant of low DO, such as the fathead minnow and brook stickleback.

Environmental Baseline Study: Fish and Aquatic Resources Section 3: Results

3.2.3.3 Site AC-2 (Reference Site)

Backpack electrofishing was done along a 200-m section of the creek at Site AC-2, for a total effort of 517 s. This sampling resulted in the capture of two species: fathead minnow (n=66) and brook stickleback (n=62). The surveyed section of stream contained very poor habitat for sportfish species, due to shallow water depth and presence of numerous beaver dams creating movement barriers. However, the area does provide suitable spawning and rearing habitat for minnow species such as fathead minnow and brook stickleback. Overwintering potential at this site was considered to be low due to shallow water depths; however localized small pools likely provide sufficient overwinter habitat for the resident species.

3.2.3.4 Resource Use

No recreational use of Astotin Creek was observed in either location. The lower portion of the stream is currently highly affected by agricultural land practices and cattle grazing.

Environmental Baseline Study: Fish and Aquatic Resources Section 4: Summary

4 Summary

An environmental baseline study of fish and fish habitat in waterbodies characterized fish communities and aquatic habitats in and near the TOTAL lands. Study areas for the field survey included an LSA, which focused on watercourses near the TOTAL lands (Astotin Creek) and the reach of the North Saskatchewan River adjacent to and downstream of the TOTAL lands. Fish and fish habitat field data were collected on the North Saskatchewan River between July 26 and August 7, 2007 and Astotin Creek on August 1 and August 3, 2007. Field sampling for benthics and periphyton was completed during fall 2007, and the results will be described in an addendum report. The North Saskatchewan River was systematically sampled throughout four sections in the LSA to provide sufficient data to describe the local summer-season fish communities and to cover all habitat units. Two locations were assessed on Astotin Creek: one downstream of the TOTAL lands and the second, a reference location, approximately 18 km upstream from the lower site. The North Saskatchewan River in the LSA is predominantly single-channelled, and exhibits an irregular meander pattern. The river is entrenched and laterally stable, with a defined thalweg. In the survey section, instream conditions are characterized by deep Run habitat (R1; average depth greater than 1.25 m). Several deeper areas were identified; soundings during the aquatics survey indicated a maximum depth of 5.2 m in Section 1. In the surveyed section of the North Saskatchewan River, approximately 65% of the banks assessed were erosional. E3 bank habitat was most common, accounting for over 28% of the total bank assessed. This habitat type typically has high, steep, eroding banks, loose till deposits and moderate to high offshore velocity and depth. During the study period, discharge of the North Saskatchewan River ranged between 155.2 m3/s and 336.7 m3/s. The North Saskatchewan River is subject to flow regulation from upstream hydroelectric generating facilities and experiences daily water level fluctuations. During the baseline study (July 27 to August 7), the daily water level in the LSA fluctuated between 0.21 and 0.67 m. A total of 405 fish comprising 15 different species were encountered in the mainstem North Saskatchewan River LSA during the baseline study. Sportfish species encountered during this summer period included northern pike, walleye, sauger, goldeye, mooneye, burbot and lake sturgeon. Approximately 17.9 km of the North Saskatchewan River was sampled by boat electroshocking, with 274 fish being captured or observed, including seven sportfish and eight non-sportfish species. The majority of the sportfish catch consisted of goldeye (n=33). The remainder of the sportfish catch consisted of mooneye (n=20), walleye (n=13), northern pike (n=5), sauger (n=5), lake sturgeon (n=2) and burbot (n=1). Non-sportfish were considerably more abundant than sportfish (n=195) in the electrofishing catch. White sucker was the most abundant member of this group, accounting for 46.5% of the non-sportfish species catch by electrofishing.

Environmental Baseline Study: Fish and Aquatic Resources Section 4: Summary

CPUE values overall were low; however, these values were similar among sections. Although some minor differences in distribution of species were noted among sections, these differences can be attributed to the local availability of suitable habitats and cover. Use of aquatic habitats in the North Saskatchewan River varies according to fish species requirements, and is dependent on time of year and life history activity (i.e., spawning, feeding or rearing). Generally, most sportfish appeared to be healthy, although some external abnormalities were detected. Lesions were noticeably more prevalent on white sucker. Sportfishing (angling) occurs throughout the North Saskatchewan River in and downstream of Edmonton. In the LSA, the primary points of public access for angling are the confluence of the Sturgeon River, the Highway 45 bridge crossing and the Redwater River confluence. Use of the North Saskatchewan River by boaters and shore anglers was recorded on an opportunistic basis, with a low degree of use noted during the period of the baseline survey. Astotin Creek in the LSA flows through primarily agricultural lands, and riparian habitats are heavily affected by cattle pasturing. Surveyed sections of Astotin Creek contained limited potential sportfish habitat, but did provide suitable habitat for minnow-type species tolerant of low DO, such as the fathead minnow and brook stickleback.

Environmental Baseline Study: Fish and Aquatic Resources Appendix A: Habitat Codes

A.1 Stream Habitat Classification System (Modified from O’Neil and Hildebrand 1986) A Riffle – Portion of channel with increased velocity relative to Run and Pool habitat types; broken water surface due to effects of submerged or exposed bed materials; relatively shallow (less than 0.25 m) during moderate to low flow periods. • Riffle (RF) – Typical Riffle habitat type; limited submerged or overhead cover for juveniles and adult life stages; coarse substrate. • Riffle-Boulder Garden (RF/BG) – Riffle habitat type with significant occurrence of large boulders; availability of significant instream cover for juveniles (to lesser extent adults) at moderate to high flow events. B Rapids (RA) – Portion of channel with highest velocity relative to other habitat types. Deeper than Riffle (ranging from 0.25 to 0.5 m); often formed by channel constriction. Substrate extremely coarse; dominated by large cobble and boulder material. Instream cover provided in pocket eddies (P3) and associated with cobble/boulder substrate. C Run – Portion of channel characterized by moderate to high current velocity relative to Pool and Flat habitat; water surface largely unbroken. Deeper than Riffle habitat type. • Run Class 1 (R1) – Highest quality Run habitat type. Maximum depth exceeding 1.5 m; average depth 1 m. High instream cover at all flow conditions (submerged boulders/bedrock fractures, depth). Generally of deep–slow type (to lesser extent deep–fast) and situated proximal to upstream food production area (i.e., RF, R3). • Run Class 2 (R2) – Moderate quality Run habitat type. Maximum depth reaching or exceeding 1 m, generally exceeding 0.75 m. High instream cover during all but low flow events (baseflow). Generally of either deep–fast type or moderately deep–slow type. • Run Class 2/Boulder Garden (R2/BG) – Moderate quality Run habitat type; presence of large boulders in channel; high instream cover (boulder, bedrock fractures, turbulence) at all but low flow events (baseflow). Depth characteristics similar to R2; however, required maximum depth lower due to cover afforded by boulders. • Run Class 3 (R3) – Lowest quality Run habitat type. Maximum depth of 0.75 m, but averaging <0.50 m. Low instream cover at all but high flow events. • Run Class 3/Boulder Garden (R3/BG) – Similar to R3 in depth and velocity characteristics; presence of large boulders in channel offers improved instream cover during moderate and high flow events. D Flat – Area of channel characterized by low current velocities (relative to RF and Run cover types); near-laminar (i.e., nonturbulent) flow character. Depositional area featuring predominantly sand/silt substrate. Differentiated from Pool habitat type on basis of high channel uniformity and lack of direct Riffle/Run association. More depositional in nature than R3 habitat (sand/silt substrate, lower food production, low cover). • Flat Class 1 (F1) – High-quality Flat habitat type. Maximum depth exceeding 1.5 m; average depth 1 m or greater. • Flat Class 2 (F2) – Moderate-quality Flat habitat type. Maximum depth exceeding 1 m; generally exceeding 0.75 m. • Flat Class 3 (F3) – Low-quality Flat habitat type. Maximum depth of 0.75 m, averaging less than 0.5 m.

Environmental Baseline Study: Fish and Aquatic Resources Appendix A: Habitat Codes

E Pool – Discrete portion of channel featuring increased depth and reduced velocity (downstream oriented) relative to Riffle and Run habitat types; formed by channel scour. • Pool Class 1 (P1) – Highest-quality Pool habitat type. Maximum depth exceeding 1.5 m; average depth 1 m or greater; high instream cover at all flow conditions (submerged boulder, bedrock fractures, depth, bank irregularities). Generally featuring high Riffle or Run association (i.e., food input). Often intergrades with deep–slow type of R1. • Pool Class 2 (P2) – Moderate-quality Pool habitat type. Maximum depth reaching or exceeding 1 m, generally exceeding 0.75 m. High instream cover at all but low flow events (baseflow). • Pool Class 3 (P3) – Low-quality Pool habitat type. Maximum depth of 0.75 m, averaging <0.5 m. Low instream cover at all but high flow events. Includes small-pocket eddy type habitat. F Impoundment – Pools formed behind dams; tend to accumulate sediment/organic debris more than scour Pools; might have cover associated with damming structure. • Impoundment Class 1 (IP1) – Maximum depth exceeding 1.5 m; average depth 1 m or greater. • Impoundment Class 2 (IP2) – Maximum depth reaching or exceeding 1 m, average depth generally exceeding 0.75 m. • Impoundment Class 3 (IP3) – Maximum depth of 0.75 m, averaging <0.5 m. G Backwater (BW) – Discrete, localized area of variable size, exhibiting reverse flow direction; generally produced by bank irregularities; velocities variable but generally lower than the main flow; substrate similar to adjacent channel, but with higher proportion of fines.

A.2 River Habitat Classification System

1. Instream (River) Habitat Classification (adapted from RL&L 2001)

Riffle – Portion of channel with moderate velocity; broken water surface due to effects of bed materials; shallow water depth (0.5 m).

Run – Portion of channel with moderate velocity; surface water unbroken; nonlaminar flow.

Flat – Portion of channel with low to very low velocity; surface water unbroken; laminar flow.

Pool – Portion of channel with very low velocity; surface water unbroken; laminar flow; water depth exceeds 2 m.

Shoal – Mid-channel area, which consists of exposed bed material; usually associated with RIFFLE habitat.

2. Bank Habitat Classification (adapted from RL&L 1994a)

Category Code Description Armoured/Stable A1 Banks generally stable and at repose with cobble/small boulder/gravel substrates predominating; uniform shoreline configuration with few/minor bank irregularities; velocities adjacent to bank generally low-moderate, instream cover limited to substrate roughness (i.e., cobble/small boulder interstices). A2 Banks generally stable and at repose with cobble/small boulder and large boulder substrates predominating; irregular shoreline configuration generally consisting of a series of armoured cobble/boulder outcrops that produce Backwater (BW) habitats; velocities adjacent to bank generally moderate with low velocities provided in BW habitats; instream cover provided by BW areas and substrate roughness; overhead cover provided by depth and turbidity and woody debris; occasionally associated with E4 and E5 banks. A3 Similar to A2 in terms of bank configuration and composition although generally with higher composition of large boulders/bedrock fractures; very irregular shoreline produced by large boulders and bed rock outcrops; velocities adjacent to bank generally moderate to high; instream cover provided by numerous small BW areas, eddy pools behind submerged boulders and substrate interstices; overhead cover provided by depth and turbidity. A4 Rip-rap substrates consisting of angular boulder-sized materials; might be native rock or concrete debris; often associated with high-velocity areas; generally with deep water situated immediately offshore; instream cover provided by depth and turbulence; similar to A3 habitat but generally with smooth bank profile.

TOTAL E&P Canada Ltd. December 2007 Page A-5

Environmental Baseline Study: Fish and Aquatic Resources Appendix A: Habitat Codes

Category Code Description Depositional D1 Low-relief, gently sloping bank type with shallow water depths offshore; substrate consists predominantly of fines (i.e., sand/silt); low current velocities offshore; instream cover generally absent or, if present, consisting of shallow depressions produced by dune formation (i.e., in sand substrates) or embedded cobble/boulders and vegetative debris; generally associated with bar formations. D2 Low-relief, gently sloping bank type with shallow water depths offshore; substrate consists of coarse materials (i.e., gravels/cobbles); low-moderate current velocities offshore; areas with higher velocities usually producing Riffle areas; overhead cover provided by surface turbidity or surface turbulence in Riffle areas; instream cover provided by substrate roughness; often associated with bar formations and shoal habitat. D3 Similar to D2 but with greater amount of coarser substrates (i.e., large cobble/small boulder); boulders often embedded in cobble/gravel matrix; generally found in areas with higher average flow velocities than D1 or D2 banks; instream cover abundantly available in form of substrate roughness; overhead cover provided by surface turbulence; often associated with fast Riffle or Rapid areas offshore; generally moderate to high velocities offshore; transitional bank type that exhibits characteristics of both Armoured and Depositional bank types. Erosional E1 High, steep, eroding banks often with terraced profile; banks unstable, frequently slumping and eroding; substrate consists of sand/silt materials; moderate to high off-shore current velocities; steep bank profile extends under water surface resulting in deep water immediately offshore; instream cover provided by abundant submerged bankside vegetation (i.e., trees, shrubs, root wads) that have fallen into the channel from the eroding bank crest; overhead cover provided by partially submerged vegetation, depth and turbidity. E2 Similar to E1 except without the high amount of instream vegetative debris (i.e., banks generally clean); depths offshore generally shallower than along E1 banks. E3 High, steep and eroding banks, substrate consists of loose till deposits (i.e., gravel/cobble/sand mixture); moderate to high current velocities offshore; moderate depths offshore; instream cover availability limited to substrate roughness; overhead cover provided by turbidity. E4 Steep, eroding or slumping highwall bank; substrates variable but primarily consisting of fines (i.e, clays/silts); moderate to high current velocities offshore; depths offshore generally moderate to deep; instream cover limited to occasional BW formed by bank irregularities; overhead cover provided by depth and turbidity. E5 Low, steep banks, often with terraced profile; predominantly composed of silt/sand substrates; generally low current velocities offshore; depths offshore variable but generally shallow to moderate; instream cover usually absent; this bank type is often associated with BW habitats in A1 and A2 bank types; overhead cover provided by turbidity.
