Prepared in cooperation with the State of Wyoming and with other agencies
by Robert B. Swanson and others
Water resources data for the 2000 water year for Wyoming consists of records of stage, discharge and water quality of streams; stage and contents of lakes and reservoirs, and water levels and water quality of ground water. Volume 1 of this report contains discharge records for 141 gaging stations; stage and contents for 15 lakes and reservoirs; and water quality for 22 gaging stations and 21 ungaged stations. Additional water data were collected at various sites, not part of the systematic data collection program, and are published as miscellaneous measurements. These data together with the data in Volume 2 represent part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in Wyoming.
