The in-situ field parameters assessed within Salmon Creek were all adequate for supporting fish<br />
habitat. The average water temperature for both sites were below 20℃ (Table 3.8.1.A). The<br />
average dissolved oxygen concentration for the upstream site (8.61 mg/L) is well above the 6.5<br />
mg/L CCME guideline and the downstream site exceeded the 9.5 mg/L CCME guideline<br />
recommendation for early life stages with an average <strong>of</strong> 10.06 mg/L (Canadian Council <strong>of</strong><br />
Ministers <strong>of</strong> the Environment, <strong>2017</strong>). Additionally, the pH and salinity values were well within the<br />
range for natural fresh waters.<br />
The most notable parameter assessed within the Salmon Creek watershed was fecal coliforms.<br />
The upstream site fell below the recreational guideline average with an average <strong>of</strong> 149 CFU/100<br />
mL. The downstream site however, exceeded this guideline with an average <strong>of</strong> 583 CFU/100 mL.<br />
As seen in Figure 3.8.1.A, the fecal coliform concentration spiked at the downstream location in<br />
July and remained high in the August sampling two weeks later. Between the upstream and<br />
downstream sites there is a waste water treatment facility (<strong>of</strong>f <strong>of</strong> Longwood Drive) that may have<br />
contributed to this spike. As stated previously, prolonged high fecal coliform concentrations can<br />
have other negative effects on water quality and act as chemical barrier to fish species.<br />
