A.M. Campbell 2007 Introduction The Water Resources Division of the U.S. Geological Survey, in cooperation with Federal, State, and local water agencies, collects a large amount of data each year pertaining to the ground-water resources of Idaho. These data constitute a valuable database for developing an improved understanding of the water resources of the State. Beginning with the 1985 water year and continuing through 2005, data were published in a report series entitled, 'Water Resources Data for Idaho, Ground-Water Data.' Prior to the introduction of that series, historical ground-water information was published in U.S. Geological Survey Water-Supply Papers. In 2006, the ground-water data reporting requirement was discontinued. However, data continue to be available in our databases. This fact sheet serves as an index to ground-water data for 2006. application/pdf 10.3133/fs20073031 en Geological Survey (U.S.) Availability of Ground-Water Data for Idaho, Water Year 2006 reports
