BMIBI Score Explained
This site was analyzed using the BMIBI-Cold Water assessment methodology.
A detailed analysis of the IBI score has not yet been determined for coldwater IBI metrics.
This location has been classified as a Reference Site. Reference sites represent natural stream qualities that are least disturbed by human activities within the watershed. These sites are then grouped by ecoregion to establish a benchmark against which other streams in the same ecoregion are compared.
