[!] 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.
