Groundwater level data in Alaska are summarized for the 1983 water year for observation wells at which levels are either recorded continuously or measured intermittently. For wells at which water levels are measured semi-annually, 10-year summaries are presented. Water levels for 153 observation wells are shown on graphs and locations of the wells are shown on accompanying maps. The following information is given for each well: location , owner, type of aquifer, depth and casing information, type of measurement, altitude datum, period of record, and extremes for the period.
