Biomonitoring Retrospective: Fifteen Year Summary for Maine Rivers and Streams. This report includes the results of fifteen years of biological monitoring effort and provides a summary of the results of biological monitoring of benthic macroinvertebrates in rivers and streams, between 1983 and 1998, in the State of Maine, by the DEP.

Biological Water Quality Standards to Achieve Biological Condition Goals in Maine Rivers and Streams. This publication describes the philosophy, history, methodology, and management applications of numeric biological criteria in water quality standards in Maine. The presentation describes the decision-making process used by the Maine Department of Environmental Protection (MDEP) for assessing attainment of aquatic life uses in water quality standards using benthic macroinvertebrates in Maine streams and rivers including eight case studies of management applications and the improved environmental outcomes that have resulted.

Chapter 579. Classification Attainment Evaluation Using Biological Criteria for Rivers and Streams

General Glossary for the Biological Monitoring Program

Effects of Urbanization on Aquatic Life of Maine Streams. The first part of this technical report summarizes the variety of factors that can make a stream more or less vulnerable to development within its watershed. The second part of the report presents the results of study about the effects of impervious cover on algal and macroinvertebrate communities.

Effects of Urbanization on Maine's Streams. This pamphlet summarizes the main findings of the report.
