Wyoming Water Resources Data, Water Year 2002

Prepared in cooperation with the State of Wyoming and with other agencies

by Robert B. Swanson and others


Water resources data for the 2002 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 156 gaging stations; water quality for 33 gaging stations and 34 ungaged stations, and stage and contents for one reservoir. 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.

To view or print the PDF files, you will need Adobe Adobe Acrobat Reader®, version 4.0 or higher. The reports also are available on CD-ROM, and a copy may be obtained by contacting Wyoming State Representative, (307) 778-2931, ext. 2872.
