States and Tribes

Why Use Biocriteria and Bioassessment Data?

Biological assessments and criteria can be an important component of State and Tribal watershed management programs by assisting in prioritization and targeting of actions, setting restoration goals and performance standards, and documenting results.

Steps in Developing a Bioassessment and Biocriteria Program

EPA recommends a phased, iterative approach to developing a bioassessment and biocriteria program. A brief description of the phases and links to more details from EPA guidance are provided.

Biocriteria in the Water Quality Criteria and Standards Plan

The Water Quality Criteria and Standards Plan is a vision for the future of the water quality standards and criteria program. The plan describes new criteria (including biocriteria) and standards program initiatives that EPA, the states, and Indian tribes will take during the next decade.

Adopting Biocriteria into State and Tribal Water Quality Standards

EPA recommends a phased, iterative approach to the adoption of biological
criteria into state and tribal water quality standards that integrally links the
development of biocriteria with refinement of a state's or tribe's classification
system for designated aquatic life uses.

How To Get Started

We are looking for examples from states on how they have initiated bioassessment and biocriteria programs. By viewing different approaches around the country, other states and tribes may be able to take advantage of these experiences and lessons learned.

How To Fund A Program

Many of the concerns of states and tribes relate to the resources needed to develop bioassessment and biocriteria programs. We would like other states and tribes to share some of their successful experiences with us.

Cost Estimates and Resource Requirements for Maine’s Bioassessment and Biocriteria Program

Learn about State and Tribal Programs

Several states and Indian tribes have active bioassessment and biocriteria programs.   Learn about specific state and tribal programs and visit some state program web sites.
