ABSTRACT. Building upon insights from fishery managers and multi-decadal studies on trout populations, the state of Michigan embarked on a statewide program to monitor trends in wild trout populations and to characterize (i.e., assess the status of) fish assemblages and habitats in all streams. Initiated in 2002, the Status and Trends Program is providing a rich set of information from standardized surveys across Michigan. Data from this program support public-facing tools which inform stakeholders (biologists, anglers, various publics) of trends in highly-valued trout populations and provide a scientific, quantitative basis for making management decisions on individual stream reaches. Launched in 2014, the Fish Population Trend Viewer Trend Viewer allows users to assess trends in wild trout abundance, growth, and survival using data from index sites scattered across the state. A companion tool for evaluating fish assemblage and habitat characteristics for streams is scheduled for release in 2017. The Michigan Stream Evaluator will compare conditions at an individual site with benchmarks computed from surveys in streams having user-specified size, temperature, channel gradient, and geographic location attributes. Both tools are refreshed annually with additional stream survey data collected for the Status and Trends Program.
