Freshwater flow in the Hackensack River has been drastically reduced for use as drinking water by the Oradell Dam. The navigable ship channel on the river has only been maintained as far north as the Riverbend in Hudson County. The accumulation of silt has effectively filled in the formerly navigable channel. The present depth of the Hackensack River is too shallow to allow the Ling to move downstream, and there are no funds or plans to dredge the river, the muds of which are laced with industrial toxins. The Ling therefore cannot be moved from its location.
