FoRR took to the river on February 11 and 15 to monitor at five sites in the Reedy River watershed! Our sites include the following:
The pH results for February were consistent with January's findings at all five of our reported sites. Conductivity was also consistent at the sites where it was sampled.
The dissolved oxygen (DO) for all sites was very consistent from January to February, more or less maintaining January's increased DO levels. These consistent results are likely due to consistent weather patterns in the weeks preceding both month's sampling events. The only site that showed a noticeable change was Falls Park with an increase of 1.0 mg/L (up to 10.3 mg/L from January's 9.3 mg/L). We expect the DO levels to begin to drop as water and air temperatures increase with the spring temperatures in the coming months. Warmer water has lower capacity to store dissolved oxygen, plus as aquatic organisms begin to become more active, their metabolisms will increase which in turn causes an increased demand on the dissolved oxygen for use by these critters.
E. coli bacteria levels showed very minor fluctuations, but are all normal for this time of year and consistent with our findings from last month. We can also expect to see bacteria levels gradually increase once again as the temperatures rise. Not only does warmer water foster a better habitat for e. coli (a rare situation where habitat improvement is NOT desirable!), but we will also see the return of waterfowl along our streams, particularly near Falls Park, which leads to increased introduction of e. coli to our waters. Because of this, we expect to see a gradual increase in e. coli bacteria colony forming units as temperatures begin to rise.
We have included the SC State Standards below for comparison to our results.
