It had to happen sooner or later. In this case it was the later.
The Delaware River at the Riegelsville gage has fallen below 4' for the first time this year. In other words it's getting back closer to the median flow for this time of year. A similar reading can be found at the Belvidere gage, and that is several hundred CFS above the median flow. The river will fall further depending on the intensity of thunderstorms over the next 12 hours. All the tributaries are significantly down from the vigorous flows observed just a week or two ago.

I am receiving the Musconetcong River at Bloomsbury and the Delaware River at Riegelsville. The statewide gages for NJ, NY and PA can be found on my 'links' list.
