Described here are the standard operating procedures (SOPs) for completing a level-one biosurvey. These
SOPs are designed and intended for the assessment of wadeable streams; they consist of three basic elements:
- Water Quality Analysis
- Phyical and habitat evaluations mostly by observations using conditions described on the survey data
- Collection and assessment of the BMI community
The order of the procedures can vary slightly, depending upon the number of volunteers available to
perform the survey. However, water quality analysis and physical evaluations should occur prior to
sediment disturbance that may be caused by walking in the stream. See the sections below for review.
