The majority of the macro-invertebrates we found and identified have a medium tolerance level. We found 4 macro-invertebrates in the range of 0 to 3 tolerance level. We found 124 macro-invertebrates in the range of 4 to 7. We found 14 macro-invertebrates in the 8 – 10 range. With the high level of rain received this spring, our stream’s velocity increased compared to the spring data. The depth and width also increased compared to fall.
