Changes in water and habitat quality of Kordan Stream were examined using community structure and biotic indices at 3 sites during [2008][2009]. This investigation resulted in inventories of benthic insect communities being obtained from this stream. It also resulted in two metrics being calculated from benthic insect communities. Of the metrics used, one indicated EPT taxa richness and one involved a biotic index, HFBI, for organic pollution. Water temperature, water velocity, water depth, dissolved oxygen, BOD5, pH, specific conductivity; phosphate and nitrate concentrations were within ranges usually capable of supporting a diverse biota. Samples were dominated by insects and yielded 142 macroinvertebrate taxa. The scores calculated for HFBI was lowest (4.67) and rated good water quality (some organic pollution probable) at site 1 and increased to 5.45 rated fair (fairly substantial pollution likely) at site 3. EPT ratings were "under a little perturbation" at three sites, suggesting high taxa richness and habitat quality in Kordan Stream.
