The majority of the macro-invertebrates we found and identified have a medium tolerance level. We found 1 macro-invertebrate in the range of 0 to 5 tolerance level. We found 240macro-invertebrates in the range of 6 to 10. With the low level of rain received this summer, our stream’s velocity decreased compared to the spring data. Because of the lower velocity the higher number of bugs are able to stay in the stream.
