AbstractBuried-valley aquifers occur across the Canadian Prairies with a lack of surface expression and complicated network geometries. As part of an effort to map and characterize the Hatfield buried-valley aquifer, the Geological Survey of Canada commissioned a helicopter time-domain electromagnetic survey consisting of 2617 line-km of data over 940 km2 near Esterhazy and Rocanville in southeastern Saskatchewan. Survey results are presented as apparent-conductivity maps and as 3D conductivity-depth models. The Hatfield and Rocanville buried valleys are clearly imaged along with several other erosional and depositional features, some of which have been previously identified at the local scale and are currently utilized as groundwater resources, but for which the extent has not been fully mapped. Other features identified in the survey represent potentially new groundwater resources and can be used to help unravel the details of valley formation, groundwater flow, and aquifer recharge.
