Most of Saskatchewan is underlain by up to 300 m of glacial
sediments. These sediments are an important source of water for farms
and municipalities. Sources are found in three distinct aquifers. The
first are from sand and gravel layers found deposited within the
sediments These aquifers are quite variable in size and can be
vulnerable to changes in precipitation. The second are buried valley
complexes or preglacial valleys cut into the bedrock and infilled with
glacial deposits. These aquifers are generally high yielding and have
been extensively mapped. The third are preglacial bedrock aquifers
surface laid down by ancient seas. They are generally quite deep
and more drought proof, but are of poor quality due to high
mineral or salt contents.
