Water Level Alerts



Water level alerts originate from a continuous water level sensor network in the Hackensack River. When water levels exceed 4.5 Feet (NAVD88) alerts are broadcasted as E-mails and/or Text messages to subscribers and new elevations are broadcasted until the waters receed. Past experiences show that serious flooding in the NJMC District occurs when water levels reach 7 feet.
