About the Program - Key Activities - Technical Guidance for Developing Bioassessment Methods and Biocriteria

EPA is developing a series of technical guidance manuals for developing bioassessment methods and biocriteria. These manuals provide states and tribes with scientific information and procedures used to conduct bioassessments and develop biocriteria. These methods are then applied regionally by states and tribes as they develop the biocriteria.

EPA has published guidance manuals for the following waterbody types:

• Streams and Small Rivers (1996)
• Lakes and reservoirs (1998)

EPA is developing guidance manuals covering the following waterbody types:

• Estuaries and Near Coastal Waters
• Statistical Guidance on Biological Data Analysis
