Distribution of Hydraulic Head in the Scollard / Willow Creek Hydrostratigraphic Unit (gridded data, ASCII format)

This grid represents the distribution of hydraulic head in the Scollard / Willow Creek hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available data from the following sources:

1. Alberta Environment and Parks' (AEP) Alberta Water Well Information Database (AWWID).
2. Pressure data from drillstem tests (DSTs) from oil and gas wells.

The hydraulic head surface was mapped at a regional scale using many years of data, thus providing a good indication of regional groundwater flow within the unit rather than site-specific values.
