Water-resources data for the 2002 water year for New Mexico consist of records
of discharge and water quality of streams; stage, contents, and water quality
of lakes and reservoirs; and water levels and water quality in wells and springs.
This report contains discharge records for 176 gaging stations; stage and contents
for 24 lakes and reservoirs; water quality for 42 gaging stations, 108 wells,
and 9 partial-record stations and miscellaneous sites; and water levels at 135
observation wells. Also included are 80 crest-stage, partial-record stations.
Additional water data were collected at various sites not involved in the systematic
data-collection program and are published as miscellaneous measurements. Two
seepage investigations were made during the year. These data represent that
part of the National Water Data System collected by the U.S. Geological Survey
and cooperating Federal, State, and local agencies in New Mexico.
