Volunteer Stream Quality Monitors from the Friends of the Lower Olentangy Watershed have sampled 21 locations at 11 Olentangy River tributaries in the past two years.   The sites are sampled for various organisms that could be found in small streams, then assigned a score based on the number of different organisms found. The score is called the Cumulative Index Value (CIV).  The greater the diversity, or number of different types of organisms found, the higher the cumulative index score. The scores for the CIV can range from 1 to 25, where a higher number reflects a higher diversity of organisms and is indicative of better water quality and habitat in the stream.

Below are links to stream quality report cards for several tributaries within the lower Olentangy River watershed. The report cards also identify specific causes of water quality problems in the stream.

Glen Echo Run  (CIV = 7.3)

Slyh Run (CIV = 6.9)

Rush Run  (CIV = 9.5)
