Water resources data for Iowa for the 2005 water year consists of records of stage, discharge, and water quality of streams; stage, and/or contents of lakes and reservoirs; ground-water levels and water quality of ground-water wells and precipitation. This report volume contains discharge records for 136 gaging stations; stage or contents for 9 lakes and reservoirs and 6 streams; water quality for 18 stream-gaging stations; sediment records for 7 stream-gaging stations; precipitation record for 7 precipitation stations; peak-flow data for 88 crest-stage partial-record stations; water levels for 24 ground-water observation wells; water-quality data for 154 municipal wells; and precipitation-quality data from 2 precipitation sites.
