OR002 Ground-Water Stations
Study area
PROJECT CHIEF: William D. McFarland
LOCATION: State of Oregon
PROJECT EXTENT: Statewide
PROBLEM
Long-term water-level records are needed to evaluate the effects of climatic
variations on the recharge to and discharge from ground-water systems, to
provide a data base from which to measure the effects of development, to assist
in the prediction of future supplies, and to provide data for management of the
resource.
OBJECTIVE
- A. To collect water-level data sufficient to provide a minimum long-term data
base so that the general response of the hydrologic system to natural climatic
variations and induced stresses is known and potential problems can be defined
early enough to allow proper planning and management.
- B. To provide a data base against which the short-term records acquired in
areal studies can be analyzed. This analysis must:
- Provide an assessment of the ground-water
resource,
- Allow prediction of future conditions,
- Detect and define
pollution and supply problems, and
- Provide the data base necessary for
management of the resource.
APPROACH
Evaluation of regional geology allows broad, general definition of aquifer
systems and their boundary conditions. Within this framework, and with some
knowledge of the stress on the system in time and space and the hydrologic
properties of the aquifers, a subjective decision can be made on the most
advantageous locations for observation of long-term system behavior. This
subjective network can be refined as records become available and detailed
areal studies of the ground-water system more closely define the aquifers,
their properties, and the stresses to which they are subjected.
