Click to hide state-specific text

Questions or concerns about USGS data and data products in Wyoming and Montana can be directed to the Wyoming-Montana Water Science Center Data Management Section.

UPDATED June 1, 2023: The entity that had been funding these stations needs to discontinue that funding as soon as possible. These gages will be discontinued on August 1, 2023 if alternative funding can not be secured:
  • 09209400 Green River Near LA Barge, WY
  • 09213500 Big Sandy River Near Farson, WY
  • 09218500 Blacks Fork Near Millburne, WY

Please contact the Wyoming-Montana Science Center for more information.
To view additional data-quality attributes, output the results using these options: one result per row, expanded attributes.
Additional precautions are here.
