The imposing 40-foot high U.S. Geological Survey (USGS) streamgaging station on the Delaware River at Montague, N.J. was established in 1939 and has been in continuous operation since then. A data collection platform on top of the station uses satellite telemetry to deliver streamflow information in real time. A critical link in the USGS network, this station is used to monitor flow and releases from the New York City reservoirs into the headwaters of the Delaware River Basin, as required by the Supreme Court Decree of 1954.
