The river conditions information compiled on these pages has been provided by numerous public and private sources other than the Delaware River Basin Commission. Major contributors of data and interpretive material include the National Weather Service, U.S. Geological Survey (USGS), and the U.S. Army Corps of Engineers. In many cases, the information is provisional; accordingly, the data may be subject to change or revision.

Emergency managers and all others involved with water management decisions should reference USGS web sites as the primary source for real-time stream flow data. USGS data are reviewed and corrected often, thus offering the most accurate information for decision making.
