Water levels and gradients are a consequence of the nature of geological media and their study helps to define the hydrogeological environment. In this paper, water levels of wells in a typical weathered and fractured granitic environment of Shadnagar Basin, Andhra Pradesh were analyzed. These studies indicate the hydraulic continuity and unity of ground‐water flow systems in weathered and fractured granites contrary to the conclusions of earlier workers. Also, the long‐term behaviour of hydrographs reveals that the basin is not over‐developed and precipitation is the only source of recharge to the ground‐water system.
