The C1 Waters Story Map is an interactive application designed to deliver all relevant information on C1 waters to the public.

What information is available on the Story Map? Users can view information on the State’s antidegradation designations, criteria used to designate C1 waters based on an exceptional significance, protections afforded to C1 waters, and a C1 timeline. Users are able to take a close look at C1 waters along with background information for the exceptional significance attributed to a designation, and can access C1-related map coverages all in one tool.

Click on the tabs below and left, for instructions on using the C1 Waters Story Map.

The landing page of the application opens on the first tab of the Story Map, titled “Introduction to C1 Waters”. Click on the stacked accordions to uncover answers and helpful infographics to Frequently Asked Questions.

Information on the definition of C1 waters, designation criteria, protections applicable to C1 waters, and a timeline of C1-related rulemakings are provided in this tab by clicking on accordions.



The second tab of the Story Map, “Map - All Category One Waters”, features a map showing C1 streams in New Jersey as a LINE layer, which becomes more detailed as you zoom in.

This map also includes a POINTS layer for background information on C1 streams that were designated based on an exceptional significance.



By clicking on the Legend tab on the top right (circled in purple), one may view different exceptional significance qualifiers for C1 waters, and read through stream classification acronyms.

Click on the Address Search icon (circled in red) to type in an address to view nearby C1 waters.

Click on the Find My Location icon (circled in green) to immediately zoom to your device’s current address.

Zoom in to a C1 water, and click on a point to view more information on the basis for that particular stream’s exceptional significance designation. More information on the designation can be found in the ruling by date at SWQS Rules in the Rule Amendments tab.



The third tab of the Story Map, titled “Map - 2020 Category One Upgrades and Trout Reclassifications” features content related to the most recent 2020 C1 Adoption.



In the Layer List (outlined in red), select map coverages that you are interested in viewing. The Layer List provides a specialized selection of GIS layers that tie into the Surface Water Quality Standards when determining stream classifications, antidegradation protections, and more.

Use the Address Search tool (outlined in orange) to zoom to a desired location.

Use the Measurement tool (outlined in purple) to measure the distance between two features on the interactive map.

To use the tool to measure distances, select the distance ruler icon (). Next, click on the starting point location; move your mouse to the destination and click again to establish your ending point. The measurement result will appear, which can be adjusted to your desired units.


Use the Legend (outlined in green) to view all the written acronyms for surface water classifications.
