The report describes a framework for conducting stream bioassessments and how it is used to evaluate the biological condition of Iowa's wadeable rivers and streams. The document also serves as a foundation for developing biological water quality standards for the protection of designated aquatic life uses and measuring progress toward the achievement of Federal Clean Water Act goals.
