The Eastern Montana Stream Temperature Regression (EMonSTeR) is an expansion and update of the popular NorWeST stream temperature model produced by Dan Isaak and others at the U.S. Forest Service. It estimates mean August stream temperatures and predicts what they will be in the future. For NorWeST model methods, see Isaak et al. 2017
