"Protecting, Maintaining, and Restoring New Jersey Surface Waters"

Geographic Information System (GIS) coverages can be downloaded from the Department’s GIS digital downloads as individual data layers. These data layers may also be available through other interactive mapping applications, such as NJ GeoWeb. Numerous NJDEP GIS database layers are also available for viewing through NJ GeoWeb that provide information on State waters, Land uses, and more.

Instructions for Finding Stream Classifications and Category One Waters Using NJ GeoWeb:
  1. From the DEP home page, left side menu, below the "Information Tools," header select the “NJ-GeoWeb” or a click here.
  2. Select "NJ GeoWeb" to open the information page and click on the "Launch GeoWeb Profile" button.
  3. Since the data layers of interest on the map are only available when you are zoomed in, you must either use the “zoom in” button over a desired area or use the “Advanced tools” feature at the top left part of the screen and use “Locate Point Using NJ State Plane Coordinate”.
  4. Select only the following boxes to make the data layers available:
    1. Base Layers: Municipalities
    2. Water: Category One waters, Surface Water Quality Standards and Water Bodies
  5. Use the “i” tool and click on the stream, and from the "more information" box use the dropdown menu to select the “Surface Water Quality Standards” layer.
  6. This will provide the stream name, stream classification (FW1, FW2-TP, FW2-TM, FW2-NT, SE1, SE2, SE3, or SC) and antidegradation designation (C1) as appropriate. The Category One waters data layer will provide the same information but only if the stream is designated as Category One.
  7. Add the "subwatersheds – HUC14” data layer to determine the area upstream of the Category One segment which may be subject to 300 foot buffers.

Please note that these data layers are provided for informational purposes only and are not legally binding. When interpreting the SWQS, the written standards found in the most recently adopted SWQS rules (N.J.A.C. 7:9B) always take precedence.
