• <br />• <br />• <br />Lab analysis identified the taxonomic classification of benthic macroinvertebrate <br />samples from each sampling site. Using taxonomic keys, SHEP volunteers <br />identified the Kingdom, Phylum, Class, Order and Family of macroinvertebrate <br />organisms. Once identified, samples were sorted, labeled and scored. <br />4.2.4 Field Sampling Results <br />Historical Field Results for Clearwater Creek Site <br />Date <br /># Identified <br />Family <br />Biotic <br />Index <br />EPT <br /># of <br />Families <br />Dominant <br />Family <br />Dominant <br />Family % <br />Overall <br />Field Sampling Results: <br />9/8/07 <br />84 <br />5.9 <br />4 <br />19 <br />Heptageniidae <br />19% <br />9/8/08 <br />100 <br />5.5 <br />3 <br />17 <br />Chironomidae <br />41% <br />9/12/09 <br />152 <br />6.3 <br />5 <br />18 <br />Hydropsychidae <br />17% <br />9/11/10 <br />135 <br />4.5 <br />2 <br />10 <br />Gammaridae <br />76% <br />9/11/11 <br />363 <br />4.7 <br />4 <br />19 <br />Gammaridae <br />43% <br />10/2/12 <br />146 <br />4.6 <br />2 <br />16 <br />Gammaridae <br />55.5% <br />Cross Check Results <br />10/17/07 <br />155 <br />5.9 <br />4 <br />20 <br />Hyalellidae <br />19.4% <br />9/7/08 <br />109 <br />6.8 <br />5 <br />15 <br />Corixidae <br />22% <br />9/26/09 <br />113 <br />4.7 <br />3 <br />14 <br />Hydropsychidae <br />43% <br />▪ Tticoptera <br />w Diptera <br />• coleoptera <br />• Oligochaeta <br />• Other <br />Clearwater Creek Data Summary <br />Family Biotic Index (FBI): Our 2012 SHEP field sampling results produced a score of <br />4.6 for the Clearwater Creek site. This score corresponds to a "Good" rating on the <br />Family Biotic Index stream health chart. This is consistent with stream health scores from <br />2010 (4.5) and 2011 (4.7). <br />
