Click to hide state-specific text

[!] Over the next year, the USGS Pennsylvania Water Science Center will be updating the geodetic vertical elevation (gage datum) for many locations. Click HERE for additional information including a current list of streamgages with upcoming datum changes. This update in gage datum does not affect the location of the streamgage, nor the observed local gage height or discharge recorded at the streamgage.


! Discrete water samples data are undergoing modernization with this page no longer being updated with the latest data starting March 11, 2024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.
