States and Tribes - Steps in Developing a Bioassessment and Biocriteria Program

1. Planning - Establish a Management Framework

9. Program Assessment and Review

The steps, outlined here, for developing a bioassessment and biocriteria program involve careful planning; selection of appropriate measurements; detailed sampling design; consistent and reliable survey techniques; prudent data assessment; and responsible application of the biocriteria to protect water resources.

EPA has produced detailed guidance on the steps in this process for several waterbody types including Streams and Small Rivers, Lakes, and Estuaries. Work on Wetlands and Coral Reefs is ongoing.
