| Abstract | The Hydrogeological Regions Map depicts first order regions of Canada that have distinct groundwater systems. The country is assigned to nine regions as determined by frozen ground, geology, and
physiography. Frozen ground has a dominant affect in the continuous permafrost region and the southern limit of this region cuts across both physiographic and geological features. Geology controls surface expression of the landscape and subsurface
water-bearing characteristics, and the bedrock contacts that delineate geological terrains and basins represent the major region boundaries. Physiographic features are influenced by geology and coincide closely with geological boundaries but also
divide geological units where elevation dominates, primarily along the eastern limit of the Cordillera. Physiographic features provide hydraulic gradients for regional and local flow and combine with climatic and run-off characteristics to dictate
the regional moisture surplus or deficit that affects recharge to and discharge from groundwater systems. Moisture index isolines based on the Thornthwaite classification overlay the regions to provide a sense of moisture deficiency or surplus.
