Affiliated Researchers conducted biological habitat and water quality investigations on a section of stream located downstream of a dam proposed for removal. The benthic macroinvertebrates were sampled by Affiliated Researchers’ Scientists for identification and evaluation in accordance with USEPA protocols. The data from the benthic macroinvertebrate sampling and identification was used to measure the health of the stream as part of an EIR. Affiliated Researchers’ Aquatic Scientist identified the collected benthic invertebrates to Family and Genus taxonomic levels in accordance with recognized taxonomic authority.
