Bioassessments & Benthic Macroinvertebrates

Waterfall / Step Pool / Stream Assessments

Bioassessments & Benthic Macroinvertebrates collections were conducted this week and we had to share some photos from the field during the macroinvertebrate surveys in Harlan County, Kentucky. The above average rainfall in May 2016 revealed breathtaking waterfalls in this watershed.
