|Abstract:||The investigation of the ground-water resources of
Oklahoma by the U.S. Geological Survey in cooperation with the
Oklahoma Water Resources Board includes a continuing program to
collect records of water levels in selected observation wells on
a systematic basis. These water-level records: (1) provide an
index to available ground-water supplies; (2) facilitate the
prediction of trends in water levels that will indicate likely
changes in storage; (3) aid in the prediction of the base flow
of streams; (4) provide information for use in basic research;
(5) provide long-time continuous records of fluctuations of
water levels in representative wells; and (6) serve as a
framework to which other types of hydrologic data my be related.
Prior to 1956, measurements of water levels in observation wells
in Oklahoma were included in water-supply papers published
annually by the U.S. Geological Survey. Beginning with the 1956
calendar year, however, Geological Survey water-level reports
will contain only records
