A semidistributed hydrologic model (SLURP) was used in an attempt to establish a baseline of the water balance of the Upper Battle Creek watershed located in the Palliser triangle of southeastern Alberta and southwestern Saskatchewan. The study area is 111 km2 and is the source of water for a large region of the northern Great Plains. A GIS was used to describe the physical characteristics of the watershed, and Landsat imagery was used to identify the land cover. The model was relatively successful at representing the timing of runoff events, but it poorly represented hydrograph flow volumes and recessional limbs.
