The removal of old dams from the Raritan River in New Jersey will allow migrating fish to fully access the middle and upper portions of the river for the first time in more than a century.

The dam removal project is being done and financed by El Paso Corp. (now Kinder Morgan, Inc.), under the terms of a landmark agreement secured last year by the DEP as compensation to the public for harm to natural resources caused by past pollution facilities operated by or affiliated with El Paso.

This second Raritan River dam to be removed is known as the Roberts Street Dam and was previously known as the Dead River Dam. It straddles Bridgewater and Hillsborough townships. Its removal will open up a large segment of the Raritan River for fish spawning.

The elimination of the Roberts Street Dam will further increase water flow and habitat improvements realized from removal of the Calco Dam in Bridgewater last summer, which was the first phase of this three-step process.

The removal of all three targeted dams 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, Hillsborough, Bound Brook, Somerville and Manville.

It also will open up about 17 miles of tributaries, including portions of the Millstone River, to spawning. None of the dams were built for flood control.

The targeted dams include:

The Robert Street Dam, a 6 ½-foot-high sheet piling and concrete dam located at river mile 27.9. It was constructed prior to 1930 for purposes that are not known today. This dam failed and was reconstructed in 1963.

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 was essentially a large concrete pipe spanning the river that most recently carried and dispersed wastewater into the river for the Somerset Raritan Valley Sewerage Authority. The authority constructed a new outfall for that purpose. Calco Dam was demolished in 2011.

The Nevius Street Dam, located at river mile 27. The rock and mortar dam was built 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 future plan to ensure the river continues to feed water to these ponds after the dam is removed. Removal is anticipated in 2013.

Fish that will benefit from the removal of the dams are American shad, American eel, herring, and striped bass, which once migrated in prodigious numbers through the gravelly shallows of the Upper Raritan.

The voluntary settlement with El Paso resolved Natural Resource Damage claims made by the DEP against the Houston-based company that stemmed 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 uses funds secured from Natural Resource Damage settlements toward ecological restoration projects, typically in the same watershed or general area where resource damages occur.

Over the last two centuries, bull trout populations have declined across North America. The bull trout, Salvelinus confluentus, once thrived in the Columbia River Basin and coastal rivers of Washington and Oregon, extending north into British Columbia and Alberta.

Bull trout are members of the genus Salvelinus, which also includes Arctic char, brook trout, and lake trout. Like its relatives, male bull trout exhibit brilliant colors during the spawning season. Bull trout migrate during summer, traveling up to 150 miles from lakes and rivers upstream to their natal headwaters to spawn.

A variety of factors have been cited in the decline of bull trout. Habitat degradation and fragmentation, migratory fish passage obstacles, poor water quality, the effects of climate change, bounty fishing, and the introduction of non-native fish species.

Currently, American bull trout populations are scattered across portions of Oregon, Washington, Idaho, Montana, and Nevada. They populate several river systems including the Klamath,Columbia and Snake River Basins. In 1998, bull trout were listed as a threatened species under the Endangered Species Act.

In 2011, bull trout were re-introduced into the Clackamas River after a nearly 50-year absence. The reintroduction team included representatives from the U.S. Fish and Wildlife Service, Oregon Department of Fish and Wildlife, U.S.Geological Survey, and Mt. Hood National Forest. The project was one of several bull trout restoration programs that are ongoing in western river systems.

In Maryland, wild brook trout now have access to a few more miles of coldwater stream habitat. During the summer of 2011, the Savage River Watershed Association (SRWA) held an event to celebrate completion of the Savage River Headwater Dam Removal and Stream Restoration Project.

The project restored natural stream conditions along a 600 foot section of the upper Savage River to improve habitat for Brook trout, Salvelinus fontinalis, Maryland’s only native freshwater trout species.

In 2006 the Maryland Department of Natural Resources (DNR) listed brook trout as a "Species in Greatest Need of Conservation" leading to the development of a brook trout Fisheries Management Plan.

The plan includes a focus on the upper Savage River resource, which includes over 100 miles of interconnected streams. The area makes of 25% of all Maryland wild brook trout habitat.

The restoration project included the removal of an obsolete dam on the upper Savage River. During the 2008-2010 summer seasons, biologists with Maryland DNR’s Inland Fisheries Management Division monitored water temperatures above and below the dam.

According to biologists, peak stream temperatures exceeded 75 degrees F below the impoundment, yet never exceeded 65 degrees F above the impoundment. When stream temperatures exceed 70 degrees F for extended periods, brook trout cannot survive.

The Watershed Association and partners identified the area as a restoration site as the impoundment was not only causing a thermal impact, it also blocked fish passage to a headwater reach along the main stem of the Savage River.

The project involved the engineering and implementation of a natural stream flow that bypassed the reservoir and converted it to a wetland. Natural stream design methods were used to create in-stream structures that add aquatic habitat and provide stream bank stability.

The restoration project allowed fish access to 2.5 stream miles upstream from the preexisting dam, restored natural stream features and decreased water temperatures in the stream.

The former pond area was converted to a wetland, providing wildlife habitat, water quality improvement, and flood storage. The site will serve as a demonstration for stream restoration activities and brook trout habitat improvement projects.

The Dingell-Johnson Sport Fish Restoration Program apportionment for 2011 totals nearly $365 million, of which nearly $55 million is for recreational boating access facilities. The U.S. Fish and Wildlife Service’s Wildlife and Sport Fish Restoration Program reimburses up to 75 percent of the cost of each eligible project while State fish and wildlife agencies contribute a minimum of  25 percent, generally using hunting and fishing license revenues as the required non-Federal match.

The Dingell-Johnson Sport Fish Restoration Program funding is available to all 50 states, the District of Columbia, the Commonwealths of Puerto Rico and the Northern Mariana Islands, and the territories of American Samoa, Guam, and the U.S. Virgin Islands. States receive funds through a formula based on the land and water area of the state or territory and its total number of paid fishing license holders.

Sport Fish Restoration funds come from excise taxes and import duties on sport fishing equipment, motorboat and small engine fuels, and pleasure boats. No State may receive more than 5 percent or less than one-third of 1 percent of the total apportionment.

Fish and Wildlife agencies use the funds to pay for stocking sport fish; acquiring and improving sport fish habitat; providing aquatic resource education opportunities; conducting fisheries research; maintaining public fishing access, administering the  aquatic resource education program, and constructing boat ramps, fishing piers, and other facilities for recreational boating access.

The Wildlife and Sport Fish Restoration Programs have generated a total of more than $13.7 billion since their inception (in 1937 in the case of the Pittman-Robertson Wildlife Restoration Program, and 1950 for the Dingell-Johnson Sport Fish Restoration Program) to conserve fish and wildlife resources. The recipient fish and wildlife agencies have matched these program funds with more than $3.4 billion. This funding is critical to continue sustaining healthy fish and wildlife populations and provide opportunities for all to connect with nature.
