Abstract: This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit (HSU) C1, which contains fine-grained materials underlying coarse-grained sediments of HSU S2 in the Neogene-Quaternary succession of the Sylvan Lake sub-basin. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the structure grid.

Abstract:
This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in
the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit
(HSU) C1, which contains fine-grained materials underlying coarse-grained sediments of HSU S2 in the
Neogene-Quaternary succession of the Sylvan Lake sub-basin. This dataset supplements Alberta Geological
Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the
structure grid.
Purpose:
To form part of the Sylvan Lake sub-basin 3-D hydrostratigraphic model, used as a framework for assigning
geological information from the subsurface into groundwater flow models.

Evaluation method description:
All borehole data from the AWWID were sampled to the 25 m Provincial Digital Elevation Model (DEM) to
provide a borehole top elevation (m asl) to correlate hydrostratigraphic units between boreholes to
create hydrostratigraphic grids. This process was necessary as the elevation of AWWID water wells, in
many cases, was not available/recorded or verified, and if reported was estimated from a topographic
map, field investigation or handheld Global Positional System (GPS) device. GPS devices have accuracies
reported by the AWWID of ~1-30 m, but are of varying device quality and cannot be assessed for accuracy
between devices. Elevation values of moderate and high quality data were also checked with the DEM to
verify elevation accuracy and modified to match the DEM, if necessary. The vertical accuracy of the 25 m
DEM is stated as 5 m @ 90% in the Sylvan Lake sub-basin derived from 1:60 000 aerial photographs using
photogrammetric methods.

Evaluation method description:
10338 water wells from the AWWID were used in the study to broadly define hydrostratigraphic units in the
Neogene-Quaternary succession. The AWWID has abundant, relatively low quality data records, which
include location inaccuracies resulting in up to 10 wells with duplicate locations. In cases of
collocated data, one well per geographic coordinate was selected, based on completeness of lithological
descriptions and total depth, and duplicate wells were omitted. The original input data were classified
using unpublished hydrostratigraphic assignments to create a laterally extensive and mappable geobody.
Classification of lithological data into hydrostratigraphic units may incorporate assumptions and human
error when simplifying complex geological data, as unit geometry, extent, and description are a product
of the author’s conceptual understanding. The HSU C1 grid is for use in regional-scale groundwater
studies, as these mappable hydrostratigraphic units may be more complex or absent at the scale of a
local investigation. To optimize the HSU C1 grid for input into a numerical groundwater flow model, the
grid was extended across the Sylvan Lake model domain. Where HSU C1 is absent, the grid nodes’ elevation
is equal to the underlying HSU S1 grid plus a constant 0.10 m. The continuous HSU C1 grid, along with
other key hydrostratigraphic units, has been exported to ASCII grid format and can be used as a
framework for the creation of a groundwater flow model.

Measure description:
Water well data was considered to be relatively low quality, often containing inaccurate location and
lithology data submitted by water well contractors. Lithological descriptions from the 2007 version of
Alberta Environment’s Alberta Water Well Information Database (AWWID) were used to generate
hydrostratigraphic assignments to define the HSU C1 structure top grid. The data were checked for
obvious errors, including incorrect or ambiguous lithological descriptions and anomalous location
information. Apparent errors were flagged and compared with higher quality data where it was available,
i.e., moderate to high quality continuous cores, geophysical logs, and previously published geological
and hydrogeological maps. Where no higher quality data were available to validate flagged records, the
water well data were rejected. Additional information on data quality and the location of higher quality
data in the Sylvan Lake sub-basin is available in AGS Open File Report 2014-10.

Statement:
10338 water wells from the AWWID were used in the study to broadly define hydrostratigraphic units in the
Neogene-Quaternary succession. The AWWID has abundant, relatively low quality data records, which
include location inaccuracies resulting in up to 10 wells with duplicate locations. In cases of
collocated data, one well per geographic coordinate was selected, based on completeness of lithological
descriptions and total depth, and duplicate wells were omitted.
The original input data were classified using unpublished hydrostratigraphic assignments to create a
laterally extensive and mappable geobody. Classification of lithological data into hydrostratigraphic
units may incorporate assumptions and human error when simplifying complex geological data, as unit
geometry, extent, and description are a product of the author’s conceptual understanding. The HSU C1
grid is for use in regional-scale groundwater studies, as these mappable hydrostratigraphic units may be
more complex or absent at the scale of a local investigation.
To optimize the HSU C1 grid for input into a numerical groundwater flow model, the grid was extended

Description:
Methodology to create this grid dataset is fully documented in AGS Open File Report 2014-10.
Modelling Program used to create grid: RockWorks15
Number of data points available: 1705
Data type: A variety of low- to high-quality borehole data were used including lithologs submitted by
water well contractors and compiled by the AWWID, downhole geophysical logs collected from water
wells, and AGS continuous cores.
Algorithm used to interpolate data points: Inverse distance weighting (IDW2) with a minimum search
radius of 16 points
Cell Size: 400 m
Deterministic Grid Alteration Information: Limited manual manipulation of grids was performed, with
the exception of: 1) truncating HSU C1 below the land surface (i.e., the 25 m Provincial Digital
Elevation Model); 2) clipping HSU C1 where the unit is known not to exist (i.e., Sylvan and Gull
lakes); and 3) where HSU C1 is absent, adding a constant thickness of 0.10 m to the z-value of the
underlying grid node (HSU S1) to produce a continuous HSU C1 grid across the Sylvan Lake sub-basin
model domain.
Root mean square error: 6.1 m
The RMSE compares how similar interpolated grid values are to the original input data. This is a
global estimate of error for the HSU C1 grid and provides neither indication of how error is
distributed spatially in the model domain nor the accuracy of the input data.
