Raritan dams out, fish in
Shad, American eel, striped bass and other migratory fish will have another 10 miles of the Raritan River to navigate _ and spawn in _ once three dams are removed.
Under an agreement between the state Department of Environmental Protection and several polluters. The dam removal is being tallied as compensation to the public for harm to natural resources caused by past pollution at a refinery and three polymer plants that were operated by or affiliated with the El Paso Corp., according to DEP Commissioner Bob Martin.
The removal of the dams, financed and carried out by El Paso, will open up a nearly 10-mile stretch of the middle and upper Raritan to fish migrations for the first time in more than a century, at the same time expanding recreational opportunities along the river.
This settlement -- which the DEP termed "unique and unprecedented" -- will make "valuable habitat in the Raritan River available for fish spawning while improving overall environmental conditions in the river system," Martin said. "In addition, dam removal will make it easier for kayakers, canoeists, and other lovers of the outdoors to enjoy a river system that has been undergoing a steady and impressive ecological comeback over the years."
The settlement resolves so-calleld natural resource damage claims by the DEP against the Houston-based company that stem from contamination at EPEC Polymers Inc in Flemington, Hunterdon County; Nuodex Inc. in Woodbridge, Middlesex County; EPEC Polymers Inc. in Burlington City, Burlington County; and the Eagle Point Refinery in West Deptford, Gloucester County. Investigations and/or cleanups are under way at those sites.
The DEP plans an even broader effort to enhance fish passage or remove additional dams in the Raritan and its tributaries, including the Millstone River, the agency said.
More from the DEP press release:
"This portion of the river was once an important spawning area for fish migrating from Raritan Bay," said Amy Cradic, Assistant Commissioner for Natural and Historic Resources. "This agreement is a major win for the environment by reopening these spawning areas and helping to restore balance to the estuary."
Dam removal will open up 10 miles of migratory fish habitat along a stretch of the Raritan that twists through a highly diverse residential, commercial and agricultural portion of Somerset County that includes Bridgewater, Bound Brook, Somerville and Manville. It will also open up some 17 miles of tributaries to spawning. None of the dams were built for flood control.
The dams to be removed are:
* Calco Dam, located at river mile 20.9 and built by the Calco Chemical Co. in 1938 to disperse chemicals from its facility. The dam is essentially a large concrete pipe spanning the river that today carries and disperses wastewater into the river for Somerset Raritan Valley Sewerage Authority. The authority has constructed a new outfall that will be operational shortly.
* The Nevius Street Dam, located at river mile 27 and constructed of rocks and mortar in 1901 for aesthetic purposes and later retrofitted to provide water to ponds on the Duke estate. The DEP and El Paso are working on a plan to ensure the river continues to feed water to these ponds after the dam is removed.
* The Robert Street Dam, a 6 ½-foot-high sheet piling and concrete dam located at river mile 27.9 and constructed prior to 1930 for purposes that are not known today.
The Island Farm wier, a dam located between the Calco and Nevius dams and constructed in the 1990s for the Elizabethtown Water Co. and the New Jersey Water Supply Authority, is not affected by the agreement with El Paso. A large fish ladder in operation at this dam is routinely monitored by the DEP's Division of Fish and Wildlife.
Better water flow in the river will also improve flushing of sediments, reduce nutrient loadings and improve conditions for tiny aquatic organisms that are critical to the food web in any river system, Cradic said.
