There are only a couple of NJ streams that have a temperature reading. The Pequannock River at Oak Ridge outlet, Flat Brook, don't think there are any others. When you are pulling in that data, the others should read 0, but if they read 32 then that is also a default reading for no reading. I contacted the USGS when they stopped reporting the S Branch, that reading came off an array of equipment that had chlorophyll and stuff like that, and was there for a period of time as a monitoring project, and when it came out, the temp sensor was part of the package. They were very nice, told me they had many inquiries about it including TU, and were trying to help but the equipment they had used was now somewhere else doing the same thing. Too bad for me, it was good to know before I drove up there from S Jersey when it got warm.
