Described here are the standard operating procedures (SOPs) for completing an advanced biosurvey. These SOPs
are designed and intended for the assessment of wadeable streams; they consist of three basic elements:
- Water chemistry analysis
- Physical and habitat evaluations mostly by observations using the examples described on the survey data
- The collection and assessment of the benthic macroinvertebrate (BMI) community
The order of the procedures can very slightly, depending upon the number of volunteers available to
perform the survey. However, water quality analysis and physical evaluations should occur prior to any
disturbance that may be caused when walking in the stream.
