  <dc:description>&lt;p&gt;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.&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;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 of a selected network of observation wells, and will be published at 5-year intervals. The first of this series, for the 1956-59 period was published in 1962.&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;In addition to the water-supply papers, the U.S. Geological Survey, cooperation with the Oklahoma Water Resources Board, has published the following informal reports on water levels in Oklahoma.&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;Ground-water levels in observations wells in Oklahoma, 1956-60&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;Ground-water levels in observations wells in Oklahoma, 1961-62&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;Ground-water levels in observations wells in Oklahoma, 1963-64&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;Ground-water levels in observations wells in Oklahoma, 1965-66&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;Ground-water levels in observations wells in Oklahoma, 1967-68&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;Records of water-level measurements in wells in the Oklahoma Panhandle, 1966-70&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;Records of water-level measurements in wells in the Oklahoma Panhandle, 1971-72&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;The basic observation-well network in Oklahoma during the period 1969-70 included the following counties: Alfalfa, Beaver, Beckham, Caddo, Cimarron, Cleveland, Garfield, Garvin, Grady, Greer, Harmon, Jackson, Kingfisher, LeFlore, Major, Muskogee, Oklahoma, Payne, Pontotoc, Rogers, Sequoyah, Texas, Tillman, Wagoner, Washita, and Woodward. Table 2 includes the basic observation-well network and other wells measured by the U.S. Geological Survey.&lt;/p&gt;
&lt;br&gt;
&lt;p&gt;The data in this report were compiled and prepared for publication under the cooperative agreement for ground-water investigations in Oklahoma between the Oklahoma Water Resources Board, the U.S. Army Corps of Engineers, the Oklahoma Geological Survey, and the U.S. Geological Survey.&lt;/p&gt;</dc:description>
