Hydrologic Conditions (Streamflow, Salt Front & Groundwater)

The DRBC monitors the hydrologic conditions of the Delaware River Basin closely. Understanding real-time streamflow, the location of the salt front, groundwater conditions, tides and weather is an important part of managing the basin's water resources.

Some of the information provided in this section is compiled by the DRBC; other major contributors of data include the National Weather Service (NWS) and the U.S. Geological Survey (USGS). In many cases, the information is provisional; accordingly, the data may be subject to change or revision.
