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 survey site. Survey sites are compared to reference sites within the same ecoregion. A reference site represents natural stream qualities that are least disturbed by human activities within the watershed. Reference sites are grouped by ecoregion to establish a benchmark against which these survey streams are compared.
