The DRBC monitors the hydrologic conditions of the Delaware River Basin closely. Understanding real-time streamflow, groundwater conditions, tides and weather are all important parts of managing the Basin's water resources, including the salt front.

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.

• Information from the NWS (AHPS flood forecasts, weather, precipitation, forecast offices in the DRB)
  
  
• Information from the USGS (real-time streamflow, water science centers and more)

Emergency managers and all others involved with water management decisions should reference USGS and NWS web sites (linked above) as primary sources for real-time stream flow and forecasted river rise data.
