NOVA Gas Transmission Ltd. Supplemental Aquatic Summary Report North Montney Project March 2014/8860/10173
Sikanni Chief River (212-998700) Sikanni Chief River originates with the outlet of Sikanni Chief Lake approximately 230 km northeast of Fort St. John, BC within the Muskwa-Kechika Management Area. The Sikanni Chief River flows east then north approximately 400 km, forming the Fort Nelson River after its confluence with the Fontas River approximately 80 km southeast of Fort Nelson, BC. The Fort Nelson River flows generally northeast and drains into the Arctic Ocean via the Mackenzie River. The proposed pipeline route crosses the Sikanni Chief River approximately 120 km downstream from the Sikanni Chief Lake as well as six unnamed tributaries to the Sikanni Chief River.
Sikanni Chief River is home to a diverse sportfish community (Table 17, BC MOE 2013b). The Sikanni Chief River offers overwintering habitat for fish that spawn, rear and feed in its tributaries such as the Buckinghorse River (Woods 2001). Slimy sculpin and Arctic grayling have been previously documented within 1 km of the proposed crossing location, and rainbow trout and mountain whitefish have been documented approximately 8 km upstream (BC MOE 2013b). Burbot, flathead chub and lake chub have also been sampled throughout the system (EVS Consultants Ltd. 1980). Historical angling data from 1979 include Arctic grayling up to 48 cm in length though population declines are thought to be the result of subsequent overfishing (Woods 2001). Sikanni Chief Falls, a potential barrier to fish passage (approximately 30 m in height), is located approximately 25 km upstream from the proposed crossing and is within the Sikanni Chief Falls Protected Area (BC MOE 2013b).
Mistahae Creek (212-998700-60800) Mistahae Creek is a fourth order stream that drains primarily south for approximately 18 km into the Sikanni Chief River. The proposed pipeline route crosses an unnamed tributary to Mistahae Creek (no watershed code). The proposed crossing is approximately 13 km upstream from the confluence of the unnamed tributary with Mistahae Creek and approximately 15 km upstream from the Sikanni Chief River.
Potential barriers to fish passage have been identified on Mistahae Creek; however, both are upstream of the confluence of unnamed tributary with Mistahae Creek (BC MOE 2013a). Additional literature on Mistahae Creek and its tributaries is limited.
Caribou Creek (212-998700-48600-46200) Caribou Creek is a third order stream that flows north for approximately 14.5 km into the Buckinghorse River. The proposed pipeline route crosses Caribou Creek approximately 10 km upstream from the confluence with the Buckinghorse River. The proposed pipeline route also crosses three unnamed tributaries to Caribou Creek. Arctic grayling have been documented approximately 4 km downstream of the proposed crossing location on Caribou Creek (Table 17, BC MOE 2013b). Additional literature and documentation of Caribou Creek and its tributaries is limited.
Buckinghorse River (212-998700-48600) The Buckinghorse River headwaters are within the Muskwa-Kechika Management Area approximately 160 km northwest of Fort St. John, BC. The Buckinghorse River flows northeast for approximately 130 km to its confluence with the Sikanni Chief River. The proposed pipeline route crosses the Buckinghorse River approximately 65 km upstream from its confluence with the Sikanni Chief River as well as two unnamed tributaries to the Buckinghorse River.
Buckinghorse River has moderate gradients and moderate habitat complexity (RRCS 1989). Seasonal flow variability, low water temperatures and turbidity limit fish reproduction and growth (RRCS 1989). Arctic grayling, longnose dace and slimy sculpin have been documented throughout the system (Table 17, RRCS 1989). Arctic grayling rear in the Buckinghorse River, however, likely spawn in low elevation tributaries (RRCS 1989). Overwintering occurs in large mainstem channels or in the Sikanni Chief River (RRCS 1989, Woods 2001). Seasonal migrations are likely limited by abundant beaver impoundments (RRCS 1989).
Kahta Creek (212-998700-48600-38400-2910) Kahta Creek is a third order stream. Its headwaters originate approximately 1.5 km south of Tescla Creek, east of Highway 97. Kahta Creek flows east for approximately 17 km to its confluence with Middle Fork
Page 92
NOVA Gas Transmission Ltd. Supplemental Aquatic Summary Report North Montney Project March 2014/8860/10173
Creek. The proposed pipeline route crosses Kahta Creek twice in its headwaters approximately 16 km upstream from the confluence with Middle Fork Creek, as well as two unnamed tributaries to Kahta Creek.
No fish have been previously documented in Kahta Creek; however, Arctic grayling have been documented downstream in Middle Fork Creek (BC MOE 2013b). Additional literature on Kahta Creek and Middle Fork Creek is limited.
Tescla Creek (212-998700-48600-38400-4230) Tescla Creek’s headwaters are east of Highway 97 approximately 150 km south of Fort Nelson, BC. Tescla Creek, a third order stream, flows for approximately 10 km east and joins Middle Fork Creek, a tributary to Buckinghorse River. The proposed pipeline route crosses Tescla Creek in its headwaters (K-PWC 115) approximately 7 km upstream from the confluence with Middle Fork Creek.
No fish have been previously documented in Tescla Creek; however, Arctic grayling have documented in Middle Fork Creek (BC MOE 2013b). Additional literature on Tescla and Middle Fork creeks is limited.
3.4 Permanent Facilities No watercourse crossings (i.e., channels with defined bed and bank) were identified at the proposed permanent facility sites along the proposed pipeline route during the 2013 open water fish and fish habitat investigations. As a result, no fish or fish habitat concerns occur at the proposed Aitken, Groundbirch or Saturn Compressor Stations (Appendix F). However, a shrubby swamp was identified at the Saturn Compressor Station (see Wetlands Evaluation [TERA 2014b, Appendix F] for additional information) and a potential NCD was identified in the northeast corner of the proposed Aitken Compressor Station.
The results of the desktop and field verification of the proposed permanent facilities are summarised in Table 18

Small headwater stream lacking channel complexity and pool/riffle/run habitat. Site had some shallow, wetted areas, but lacked flow or connectivity. Channel was dry with pockets of isolated water throughout the reach. The watercourse drains into a low-lying area, approximately 100 m downstream of the proposed right-of-way (Plate 6). The substrate is dominated by fines. Numerous barriers were identified at the site (i.e., woody debris, dry sections of channel and seismic line crossing approximately 60 m upstream of the proposed right-of-way). A tributary confluence is present approximately 30 m upstream of the proposed right-of-way. Fish sampling was not conducted at the time of the 2011 or 2013 assessments since shallow water depth precluded the use of sampling techniques. Winter 2012 habitat investigations were not conducted since North Montney Project conditions were dry in fall 2011. Site was re-aligned approximately 70 m downstream following the 2011 aquatic habitat investigation. Site characteristics were verified during the 2013 aquatic habitat investigation.

ADDITIONAL COMMENTS Approximately 50 m downstream of the right-of-way the channel loses definition and becomes characteristic of an alluvial fan. Two drop structures (approximately 2 m high) are present approximately 230 m downstream at the Pine River confluence acting as a potential barrier to fish at the time of assessment (Plates 5 and 6). Relatively low North Montney Project bank heights present at proposed right-of-way, but very high and steep approach slopes due to the Pine River valley. Fish sampling was not conducted at the time of the 2011 assessment since shallow water depth precluded the use of sampling techniques. Fish sampling was not conducted in fall 2013 due to an equipment malfunction, difficult access and shallow water depth preventing deployment of minnow traps. Winter 2012 habitat investigations were not conducted since conditions were dry in fall (Aitken Creek Section) 2011. Site characteristics were verified during the fall 2013 aquatic habitat investigation. Watercourse is identified as being associated with a shrubby swamp, see Wetlands Evaluation (TERA 2014b) for additional information. Notes: 1 As specified in the Oil and Gas Activities Act, BC OGC (2010) 2 Stream class and Fish and Wildlife Timing Window of Least Risk are assumed to be equivalent to the watercourse’s receiving waterbody (i.e., Pine River) until verified with second season sampling data. n/a - not applicable; TDB - to be determined.

ADDITIONAL COMMENTS (Aitken Section) Habitat data was collected in September 2011 and was verified by an aerial survey in June 2013 after realignment approximately 1 km downstream (see Figure 3c). Hawk’s Island, approximately 2.6 km in length, separates the Peace River into two channels upstream of the right-of-way and a mid-river shoal extends downstream of the island into the proposed right-of-way. Approximately 120 m upstream of the proposed right-of-way, a dry tributary channel enters the Peace River; an island located approximately 750 m upstream on the right bank, isolating a small side channel that contains beaver activity (Plate 6). Syne/backwater sections present and abundant both upstream and downstream. Tributaries on the right bank present at approximately 1,300 m and 2,180 m downstream. A historical side channel located approximately 4.1 km downstream on the right bank has main channel connectivity at the upstream end of the side channel (Plate 5). Water quality parameters taken from a previous downstream alignment taken September 26, 2012. Winter habitat assessment was not conducted in 2012 since habitat values and existing information confirm overwintering habitat potential. No redds were observed within the zone of influence (Figure 4c). Numerous adult mountain whitefish, bull trout and suckers were observed within the assessed reach during the snorkel and redd survey (Figure 4c).

ADDITIONAL COMMENTS North Montney Project Small watercourse with poor fish habitat and sections of steep gradient (i.e., 5–10%). Channel is marginally defined in sections upstream and downstream of the right-of-way. Confluence with unnamed tributary to Mackie Creek (7415 WC11) is approximately 60 m downstream of right-of-way (Plate 5). Fish sampling data was used from 7415WC11 due to shallow water depths present at 7415WC33 and the close proximity and similar habitat features present in both watercourses. (Aitken Creek Section) Winter habitat investigations are not necessary due to near dry conditions in fall 2013.

ADDITIONAL COMMENTS North Montney Project Well defined watercourse with isolated pockets of water throughout reach that lack connectivity. Water depths precluded the use of fish sampling techniques other than electrofishing in 2011. Fish sampling was not conducted at the time of the 2013 assessment since shallow water depth precluded the use of sampling techniques. Winter 2012 habitat investigations were not conducted based on low fish and fish habitat values and poor winter habitat potential. Site was realigned approximately 20 m (Aitken Creek Section) downstream following the 2011 aquatic habitat investigation. Site characteristics were verified during the fall 2013 aquatic habitat investigation. Notes: 1 As specified in the Oil and Gas Activities Act, EPMR (2010). n/a - not applicable; BPEF - backpack electrofishing; CPUE - catch per unit of effort is the number of fish captured per 100 seconds of electrofishing; TBD - to be determined

ADDITIONAL COMMENTS Banks are armoured at existing right-of-way located approximately 20 m upstream of the proposed right-of-way. Seasonal flow barriers are likely a limiting factor to fish presence since the site was dry in fall 2011 and 2013. Small tributary enters on left bank approximately 75 m downstream of the proposed right-of-way (Plate 5). Fish sampling could not be conducted in fall 2013 as the site was dry. A dead sculpin species was observed in September 2013. The wintering habitat rating was collected during the winter 2012 habitat investigations. Site was realigned approximately 30 m upstream following the 2011 aquatic habitat investigation. Site characteristics were verified during the fall 2013 aquatic habitat investigation.
