Water Chemistry and Macroinvertebrates
We visited the stream site downstream from the dam today. We tested the water chemistry of the water, which included the pH, turbidity, or cloudiness, the amount of nitrates, dissolved oxygen, dissolved solids, alkalinity, the amount of phosphates, and the temperature. The results that we obtained from these tests showed us that this section of the stream is healthy.
We also looked at the pollution tolerance index and the different species that could be found in the stream. We found multiple crayfish, caddisfly larvae, isopods, and many other macroinvertebrates. The variety of species also proved that this section of the stream was healthy. As a bonus, we also found a northern water snake!
