The sampling procedures described in this document were designed to provide data sufficient to characterize the algal and invertebrate assemblages for the purpose of biological assessment. In addition to describing methods for sampling algae and invertebrates, we also describe methods for characterizing the main chemical and physical conditions occurring at a stream site. We designed these procedures with an eye toward standardizing sampling methods used in the biological assessments of stream water quality. The invertebrate protocols were modified from the designs used by the States of Oregon and Washington and the BLM’s National Aquatic Monitoring Center. The algae sampling protocol was modified from EPA Rapid Biological Assessment procedures. Procedures for collection of reach and site environmental data were modified from a variety of sources. These procedures produce biological data that are comparable with data derived from EPA’s Western Pilot Stream Project. These collection procedures allow analysis of biotic data with either multimetric (e.g., B-IBI) or predictive model (e.g., RIVPACS) methods. Use of these procedures will allow users to share data, express their data in terms of standardized bioassessment measures, and thus directly compare their results with all other parties using these methods. As such, these sampling methods provide a foundation on which to establish region-wide monitoring and assessment programs for quantifying stream resource condition. Their general use does not preclude use of other sampling procedures that may be needed to address the objectives of specific projects.
