A century of pumpage has lowered water levels significantly in this system. Near the center of greatest pumpage, piezometric ground-water levels have fallen an estimated 80 feet since 1890. Observation wells away from the pumping centers show a regional lowering of water levels. This report provides the basic data on pumpage locations and volumes for 238 industrial and municipal wells and well fields. Water levels from 47 observation wells are also shown. These data are needed for ongoing work to interpret ground-water conditions and predict the effects of current and future pumpage on ground-water levels.en-USThe organization that has made the Item available reasonably believes that the Item is not restricted by copyright or related rights, but a conclusive determination could not be made.
