This dataset is part of the regional hydrogeological mapping of the Calgary-Lethbridge Corridor (CLC) in southern Alberta. It represents the potentiometric surface of the Paskapoo / Porcupine Hills hydrostratigraphic unit (HSU) interpolated from wells in Alberta Environment and Parks' (AEP) Alberta Water Well Information Database (AWWID). The potentiometric surface was mapped at a regional scale using many years of data, thus providing a good indication of regional hydraulic head and flow direction rather than site specific values.
This dataset supplements Alberta Geological Survey Report 91, which includes details on the data processing and potentiometric surface interpolation in the CLC.
