Site ID: RC09
Readington Township, Hunterdon County
Stream Category: FW2-TM (Category 2, Trout maintenance waters)
Site monitors Rockaway Creek (below McCrea Mills) subwatershed (HUC: 02030105050090)
The site is located along Route 523, just North of the Merck overpass.
This site is retired and is no longer being actively monitored by RHA.
Each June, Raritan Headwaters scientists and volunteers visit 72 stream sites in the North and South Branch Raritan Watershed Region (WMA8) of New Jersey to collect data on the health of our streams. Data collected includes a sample of benthic macroinvertebrates (used to calculate the High Gradient Macroinvertebrate Index;HGMI score), an assessment of the habitat in and around the stream, and chemical conditions in the water. Chemical parameters include dissolved oxygen, phosphate, chloride, specific conductance, nitrate, turbidity, pH, and temperature. The HGMI is used by the NJ Department of Environmental Protection (NJDEP) and the US Environmental Protection Agency (USEPA) to determine if the site is meeting state and national water quality standards under the Clean Water Act.

While this site is no longer being actively monitored, all streams could benefit from keeping an intact riparian buffer and improving green infrastructure in the surrounding municipalities. This site is located within a stretch of the Rockaway Creek that is Trout maintenance, meaning that this stream is capable of supporting existing trout, but not of supporting reproductive populations. At sites like this, preservation is key.
Many people take clean water for granted, but we know it takes vigilance and hard work to protect the water in our rivers, streams and homes.
And we can’t do it alone. We need your help to ensure that everyone within our reach has access to safe, clean water that is swimmable, fishable and, above all, drinkable.
