Over the next year, the USGS Pennsylvania Water Science Center will be updating the geodetic vertical elevation (gage datum) for many locations.

Our main office is in New Cumberland, just across the Susquehanna River from Harrisburg, with additional offices in Downingtown (Philadelphia), Pittsburgh, and Williamsport.

Explore USGS monitoring locations within Pennsylvania that collect continuously sampled water data

USGS Pennsylvania Water Science Center operates about 580 real-time data collection sites acquiring information on surface water, groundwater, water quality, precipitation and ecosystem health. Data, including models, are also published for cooperative monitoring systems and investigative studies.

Since 1836, the Pennsylvania Geological Survey has been serving the commonwealth as a science-based research organization that collects, preserves, and uses data in support of objective interpretations about Pennsylvania’s geologic resources: Water. Energy. Mineral. Land
