Groundwater resources of the region are subdivided
into groundwater basins on the basis of:
- a natural boundary that does not change with
time, such as one determined by structural
features, intervening layers, or aquifer extent;
- a boundary that may change with time, such
as an underground watershed or groundwater
divide which may change in response to
pumpage or recharge; or
- a boundary designated solely for administrative
or operative reasons.
Although many basins have been designated by
the various water-resources institutions in the
region, in this report groundwater resources are
generalized into 20 basins solely on the basis of
hydrogeological factors. These include ground-water
divides of the most important regional
aquifer system, the limits of an aquifer, or important
physiographic features.
The natural boundaries of one aquifer will not
coincide with those of another aquifer. Thus, a
basin may contain several aquifers of different
ages and areal extent occurring at different depths.
