Hydrologic Conditions Across the Delaware River Basin

This ArcGIS dashboard of hydrologic data (click image to view) for the Delaware River Basin is updated daily every morning.

It is designed to give users an overview of various hydrologic conditions - flow at Montague, N.J. and Trenton, N.J., reservoir storage and salt front location - all in one place.

Please note that the conditions on this dashboard are only updated once daily and are not to be used for real-time observations.

When you select a project, a pop-up menu will provide you with a list of key attributes and a link to a pdf file of the DRBC approval. 

Please note that only projects approved since 1/1/2005 are available for display on the map.
