ABSTRACT: Climate change is expected to alter the temperature and flow regimes of rivers and streams and many species of freshwater fish are likely to be impacted. In order to provide managers with a more complete picture of how streams are likely to change we developed a set of stream classes based on fish species which are sensitive to temperature and flow metrics. We used indicator analysis to identify species which had either a positive or negative response to a set of temperature and flow metrics calculated from USGS gage station data. We grouped species based on whether they had a positive or negative response to each of the temperature and flow metrics and then calculated the relative abundance of each of these species groups at all of our sites with fish data. Multivariate regression trees were used to create stream classes based on climate data and these species groups. This information was used to assign stream classes to all stream segments within the 22 state Northeast Climate Science Center region under both current and predicted future climate conditions. This allowed us to identify areas where streams are expected to shift from one class to another and also to quantify the net change in stream classes across the entire region. Our results will be presented in the FISTHTAIL online mapper which will allow managers, decision makers, and the public to view and download the results. We believe this information can aid in identifying important places for protection and restoration, as well as quantifying the magnitude of these impacts on fish communities throughout the northeastern and midwestern United States.
