FLOW stream quality monitoring
LOWER OLENTANGY WATERSHED REPORT CARD 2021
Volunteer Stream Quality Monitors from the Friends of the Lower Olentangy Watershed (FLOW) sampled 12 Olentangy tributaries in 17 locations in 2021. The Cumulative Index Value (CIV) is a score assigned based on the number of different organisms called macroinvertebrates found in these streams. The streams are rated based on the diversity of organisms found that can only live in clean water. The higher the score, the more diverse species were found. Low scores indicate poor water quality and FLOW uses that information to target areas that need improvement.
More reports can be found in our Wiki site; many of the tributaries have their own pages with water quality reports attached.

These are a few of the macroinvertebrates that are often found when sampling our tributaries. Group 1 macroinvertebrates are the most pollution sensitive, while Group 3 are the most tolerant of pollution.
