• 2030x1_1.zip (37.7 MB), zipped Groundwater Vistas model files and ArcGIS raster files describing future aquifer conditions assuming traditional water supply sources are used to meet 2007 Council-projected 2030 water demand. Pumping rates differ from model scenario Reg_2030 by a factor of 1.1 and may be used to illustrate model sensitivity to water demand projections.
• 2030x1_5.zip (37.7 MB), zipped Groundwater Vistas model files and ArcGIS raster files describing future aquifer conditions assuming traditional water supply sources are used to meet 2007 Council-projected 2030 water demand. Pumping rates differ from predictive model scenario Reg_2030 by a factor of 1.5 and may be used to illustrate model sensitivity to water demand projections.
