USGS Annual Water-Data Report for Pennsylvania

The annual water-data report for Pennsylvania is one of a series of annual reports that document hydrologic data gathered from the U.S. Geological Survey's surface-water and groundwater data-collection networks in each State, Puerto Rico, and the Trust Territories. These records of streamflow, groundwater levels, and quality of water provide the hydrologic information needed by State, local, and Federal agencies, and the private sector for developing and managing our Nation's land and water resources.
