Viger 2016 Appendices containing one Excel file and csv files Wyoming-Montana Water Science Center, Helena, MT U.S. Geological Survey http://dx.doi.org/10.5066/F7P26W5S Fish in Northern Great Plains streams evolved to survive heat, cold, floods and drought; however changes in streamflow associated with long-term climate change may render some prairie streams uninhabitable for current fish species. To better understand future hydrology of these prairie streams, the Precipitation-Runoff Modeling System (PRMS) model and output from the RegCM3 Regional Climate model were used to simulate streamflows for seven watersheds in eastern and central Montana, for a baseline period (water years 1982–1999) and three future periods: water years 2021–2038, 2046–2063, and 2071–2088. These data are intended to accompany a journal article; they document and input and output for the PRMS model, and include 2 separate items: 1. Appendix 1 - ranges for PRMS parameters for each PRMS model (Microsoft Excel file); 2. Appendix 2 - tables 2.1-2.7 containing simulated monthly streamflows, PRMS output (multiple csv files) These model output data are provided to accompany the forthcoming journal article Potential Effects of Climate Change on Streamflow for Seven Watersheds in Eastern and Central Montana. These data document the input and output for PRMS simulations of streamflow for the O'Fallon, Redwater, Little Dry, Middle Musselshell, Judith, Cottonwood Creek, and Belt watersheds in eastern and central Montana.

PRMS models were developed for seven watersheds, calibrated to streamflow, potential evapotranspiration, and solar radiation data. Streamflow was simulated for a baseline period (water years 1982–1999) and three future periods: water years 2021–2038, 2046–2063, and 2071–2088. 20150406 Model input and output data are referenced to watershed name.
