This dataset maps a subset of the EPA stream “Assessment Units” which are included in NJ’s Federal EPA water quality reporting process (known as “305(b)”). We’ve selected those Assessment Units which cover the TP stream segments* for the latest available reporting cycle, 2010. This is virtually all of the “named” TP streams, though the EPA segments and TP segments are sometimes slightly different (the EPA segments generally cover more frontage than the TP segments by themselves). The color code tells you if the EPA segment is meeting its standards (green), impaired (red), or unknown (orange). Click on a stream segment to open up a balloon with a little more information, and click on the link embedded there to get a LOT more information about the stream and its impairments.
A key strategy for protecting wild trout streams in NJ has been to include trout production status in the core water quality classification scheme which, in turn, is supposed to regulate the actions of landowners and developers. Over the years, due to real estate boom and bust cycles, population growth, and suburban sprawl (not to mention global warming) the habitat supporting many trout streams in the state has degraded. If your favorite stream is on the “impaired” list, you may want to start showing up at environmental impact hearings. It’s also an important indicator as to whether a new stream is worth exploring, though (truth be told) many impaired streams still fish well, at least in the short term.
This is the same information available via the EPA Waters KML, but focuses on TP water and performs better in Google Earth because the information is local.

*TP Stream segments are those identified by NJDFW as supporting a self-sustaining population of wild trout.
