Case Study: Bioassessment of Glovers Creed, West Union, Iowa, Using the USEPA's Rapid Bioassessment Protocol II

Source

The Glovers Creek Watershed Protection Project aims to establish extensive agricultural conservation and management practices to protect the soil and water resources by limiting the amount of sediment, nutrients, and pesticides that enter the stream. In order to assess the effectiveness of these best management practices, biological, physical, and chemical components of water quality were examined using the Rapid Bioassessment Protocols For Use in Streams and Rivers as a template (Plafkin et al., 1989). The goal of this investigation is to examine the family-level macroinvertebrate RBP II and assess the biological condition of Glovers Creek in the early stages of the watershed protection project.

Bioassessment results indicate that Glovers Creek is moderately impaired relative to the chosen reference site. A paired-watershed approach is also examined. The shortcomings of RBP II are evaluated and suggestions are made to increase protocol applicability to this region.
