McBride Creek - 198000 - Appendix

Site Location

PSCIS crossing 198000 is located on McBride Creek approximatley 75km west of Houston, BC. PSCIS crossing 198000 is located on Nanika FSR. Crossing 198000 was located 10.1km upstream from the confluence with Morice Lake and approximately 200m downstream from the outlet of McBride Lake. Crossing 197975 is the responsibility of the Ministry of Forests and is identified as crossing R5-049 in the Coastal Bridge Registry.


Background

At crossing 198000, McBride Creek is a fourth order stream with a watershed area upstream of the crossing of approximately 83.5km2. The elevation of the watershed ranges from a maximum of 1597m to 799m at the crossing (Table 5.68). Upstream of crossing 198000, longnose sucker, white sucker, largescale sucker, peamouth chub, leopard dace, redside shiner, burbot, lake whitefish, cutthroat trout, coho salmon, rainbow trout, mountain whitefish, dolly varden, lake trout, and prickly sculpin have previously been recorded (MoE 2020b; Norris 2020).

PSCIS stream crossing 198000 was ranked as a high priority for follow up by Irvine (2021) because of the large amount of potential habitat upstream of the crossing. A summary of habitat modelling outputs is presented in Table 5.69. A map of the watershed is provided in map attachment 093L.102.

Stream Characteristics at Crossing

At the time of the survey, PSCIS crossing 198000 was un-embedded, non-backwatered and ranked as a potential barrier to upstream fish passage according to the provincial protocol 5.70">MoE (2011b). Water temperature was 12\(^\circ\)C, pH was 7.3 and conductivity was 366uS/cm. Surveys were conducted with a remotely piloted aircraft immediately upstream and downstream of the crossing with resulting images stitched into an orthomosaic and 3-dimensional model presented in Figures 5.86 - 5.87.

Stream Characteristics Downstream

The stream was surveyed downstream from the culvert for 300m (Figures 5.88 - 5.89). Total cover amount was rated as with instream vegetation dominant. Cover was also present as small woody debris, large woody debris, and overhanging vegetation (Table 5.71). The average channel width was 6.2m, the average wetted width was 5.1m and the average gradient was 1.2%. The dominant substrate was gravels with cobbles subdominant. The habitat was rated as high value for salmonid rearing and spawning.


Stream Characteristics Upstream of 198000 and downstream of 197975

The stream was surveyed immediately upstream from 198000 for approximately 135m (Figures 5.90 - 5.91). Within the area surveyed, total cover amount was rated as with large woody debris dominant. Cover was also present as small woody debris, overhanging vegetation, and instream vegetation (Table 5.71). The average channel width was 5.5m, the average wetted width was 4.4m and the average gradient was 1%. The dominant substrate was gravels with fines subdominant. Habitat value was rated as high value for resident salmonid rearing and spawning.

Structure Remediation and Cost Estimate

Should restoration/maintenance activities proceed at the site, replacement of PSCIS crossing 198000 with a bridge (14m span) is recommended.

# The cost of the work is estimated at \$`r format(my_cost_estimate() %>% pull(cost_est_1000s) * 1000, big.mark = ',')` for a cost benefit of `r as.character(my_cost_estimate() %>% pull(cost_net))` linear m/\$1000 and `r as.character(my_cost_estimate() %>% pull(cost_area_net))`m^2^/\$1000.


Conclusion

There was 198000 is 20.1km of habitat upstream of crossing rated as high value for salmonid rearing and spawning. Crossing 198000 was ranked as a moderate priority for proceeding to design for replacement.
