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


! Discrete water samples data are undergoing modernization with this page no longer being updated with the latest data starting March 11, 2024
with a full decommission expected 6 months later. Learn more about the upcoming change and where to find the new samples data in our blog.
To view additional data-quality attributes, output the results using these options: one result per row, expanded attributes.
