Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
Online annual reports (since 1999) documenting hydrologic data for Pennsylvania gathered from USGS surface water and ground water data-collection networks and information on ordering paper copies of previous years.
Links to reports for Pennsylvania on borehole geophysical studies, aquifer tests and properties, modeling, and hydrologic effects of an earthquake with links to MOC3D solute transport software package, program mission, and bibliography.
Pennsylvania digital data for watershed boundaries, county geology, and flood mapping in Arc/Info format compressed with gzip utility for downloading plus links to other sources of data.
In 1931, the USGS established a statewide network of wells in Pennsylvania to monitor water-level fluctuations. This network consists of 68 wells to monitor ground water conditions during droughts. Links to ground-water data, hydrographs, and levels.
Studies by the USGS documenting the extent of surface-water and ground water degradation associated with coal mining in Pennsylvania and the effects of mining and reclamation practices. Includes map of mine sites.
Listing of USGS research and monitoring projects on mine drainage, in order to promote cooperation and collaboration among scientists working on problems related to mining and the environment.
Consistent, historic, and up-to-date ground-water data, such as water levels collected at wells and springs, are available from the USGS National Water Information System as graphs, tables, or files to download.
Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
Consistent, historic, and up-to-date water-quality data, such as temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds downloadable from the USGS National Water Information System as graphs, tables, or files.
USGS water resources home page for Pennsylvania with links to hydrologic studies and historic and real-time data on streamflow, ground and surface water, map/GIS information, and water quality plus district and publications information
