ABSTRACT: The response of fish to human alterations of habitat conditions is of critical management and policy importance.  For example, withdrawal of groundwater from stream ecosystems can result in altered thermal regimes, and changes in fish populations.  A challenge for policy makers and managers, however, is the high degree of variability in fish population data and varying responses of fish to habitat conditions.  Several methods have been used to set policy guidelines to protect fish from anthropogenic habitat changes.  In this study, we evaluated three methods of setting temperature benchmarks for stream fishes in Michigan.  The first method (WWAT), implemented by Zorn et al. focuses on optimal thermal range for fish, the second method (TITAN) developed by Baker and King searches the data for threshold response, and the third method (CART) is a general tool for categorizing data into discrete bins.  We found that TITAN and CART generally identified similar benchmarks, whereas WWAT often resulted in a different benchmark.  Each benchmark responded to different features in the data, and as such, begs the question of what the main policy goal is.
