[!] 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.



! This page will be decommissioned in early 2026. Please find the modernized pages in WDFN that suit you best. Learn more about our modernization plans and timeline.
