As a result of increased interest in ground‐water conditions in recent years, records of water‐levels in wells are now being collected in many places in the United States for the primary purpose of determining the relation of precipitation and other natural factors to fluctuations in water‐level. In the past, records of ground‐water levels have been collected chiefly in connection with intensive investigations in areas where the water‐levels were affected by artificial withdrawals and it has not been generally possible to correlate water‐level fluctuations closely with natural factors. It now appears probable that certain methods of studying water‐level fluctuations may be utilized advantageously in areas unaffected by heavy artificial withdrawals, but these methods generally do not yield satisfactory results in areas where there is considerable pumping or artesian flow. Three such methods are presented in this paper. The methods have not been given intensive study and their practical use is therefore not yet fully known. It is hoped that their application will be further investigated. Illustrations of the methods have been taken from records of ground‐water levels in the Platte River Valley, Nebraska, collected by the United States Geological Survey in cooperation with the Conservation and Survey Division of the University of Nebraska.
