Water resources data for Montana for the 2004 water year, volumes 1 and 2, consist of records of
stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and
reservoirs; and water levels in wells. This volume contains discharge records for 134
streamflow-gaging stations; stage or content records for 18 lakes and reservoirs; and

the District office files in Helena and are available on request. These data represent
part of the National Water Data System operated by the U.S. Geological Survey and
cooperating State and Federal agencies in Montana.
