Affiliated Researchers conducted biological habitat and water quality investigations on approximately 5 river-miles of stream, located downstream of a high-hazard dam proposed for removal.  The field investigation obtained data to determine the current condition of the habitats, water quality, and biological communities.

This data is needed to provide a baseline of the conditions that will be used in support of an Environmental Impact Statement (EIS) being developed to evaluate the possible effects of the dam removal.

On site, the team of Scientists and Technicians walked and waded the 5-mile stream during an initial reconnaissance to document field observations and select representative sampling locations.  Affiliated Researchers’ Technicians utilized RTK-GPS survey equipment to collect accurate positions and elevations at each of the sampling locations.  The team utilized a sophisticated YSI ProDSS multiple parameter instrument to collect accurate water quality measurements.

Benthic macroinvertebrates were collected in accordance with USEPA protocols, and were preserved in labeled containers to be transported to Affiliated Researchers’  facility for identification.  Identification of the macroinvertebrates is being performed by Affiliated Researchers’  Senior Scientist/Entomologist who is able to key most of the specimen to Genus.

Fish specimens were collected in accordance with USEPA protocols, using a Smith-Root backpack electro-fisher.  All of the fish were keyed to Species in the field and released unharmed.

Stream habitat quality to riparian zone data were collected by Affiliated Researchers’  Aquatic Scientist in accordance with USEPA protocols
