Description:
Abstract:
This dataset is part of the regional hydrogeological characterization of the Upper Cretaceous–Quaternary units in the Fox Creek area of west-central Alberta. It represents the potentiometric surface of the uppermost bedrock units in the study area, including the Wapiti, Battle, Scollard, and Paskapoo formations interpolated from wells in Alberta Environment and Parks' (AEP) Alberta Water Well Information Database (AWWID) and elevations of several rivers within the study area that have incised the uppermost bedrock units. 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.
Purpose:
To provide the regional potentiometric surface for the uppermost bedrock units in the Fox Creek area.

Data Quality Information:
Logical Consistency Report:
Grid cell spacing is 500 m by 500 m, and any grid cells with a null value have been assigned the value -9999.
Completeness Report:
The final potentiometric surface map covers the study area and represents the uppermost bedrock units.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
The interpolated surface in the vicinity of water wells may have up to 400 m (occasionally 800 m) of horizontal error due to the positional accuracy of the water wells. Wells in the Alberta Water Well Information Database (AWWID) are frequently placed in the middle of a quarter section (occasionally a section) because their exact location within the quarter section (or section) is not known.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report:

See AER/AGS DIG 2020-0006 (data points) for details on the vertical accuracy of the input data, which is affected by the locational accuracy of the wells.

The following statistics describes the accuracy of the final grid:

Root mean square error = 23.78

Mean error = 0.245

Mean standardized error: 0.014

Root mean square standardized: 0.659

Average standard error: 34.54
