Executive Summary

Science-based management of aquatic resources requires high-quality information that is readily available to managers and stakeholders. Collecting and distributing this information is an essential role of the Michigan Department of Natural Resources (DNR) and helps the DNR to fulfill its public trust mission. This report, Status and Trends of Michigan Stream Resources, 2002-2007, provides comprehensive information needed to understand and effectively manage Michigan streams.

This report represents the first statewide assessment of stream resources and is intended for use by scientists, managers, policy makers, and the public. It provides an up-to-date summary of information on streams and characterizes the broad scale patterns in stream habitat, fish community structure, and fish population characteristics. The findings presented here document the current status of selected stream resources and establish the baseline conditions against which future monitoring results can be compared.

Michigan's streams are an abundant, diverse, and valuable resource. A growing list of environmental issues place ever-increasing demands on stream habitats, fishes and other aquatic life. The findings of this report and the continued assessment efforts of the DNR will help in the conservation and enhancement of stream resources and in the optimum use of stream resources for the benefit of the people of Michigan.
