This paper describes scenarios of climate change and water supply constructed to assess vulnerability of communities to future conditions in
the South Saskatchewan River Basin (ssrb). Output from five Global
Climate Models (gcms) forced with various future emission scenarios were
used to construct a range of future scenarios of temperature and precipitation
(i.e., median, warmest-wettest, warmest-driest, coolest-wettest, and coolestdriest) over the ssrb. Downscaling using the stochastic weather generator,
lars-wg, was also carried out at Lethbridge, Alberta, and Swift Current,
Saskatchewan, and results were compared to future scenarios derived using
the coarse resolution gcms solely
