This project will remove the upper and lower E. R. Collins Dams where the Pequest River meets the Delaware River in the town of Belvidere, New Jersey. These dams cause significant flooding issues for the town and block spawning and rearing habitat for at-risk species. This project will reconnect habitat for American shad, blueback herring, alewife, American eel and native sea lamprey, opening 3 miles of spawning ground. This project will be done in tandem with two other dam removals upstream to maximize benefits and open an additional 58 miles on the Pequest River and its tributaries. This dam removal not only removes a flood hazard, but also increases opportunities for fishing and paddling to help boost regional tourism and local economies.

The National Fish Passage Program: Leaders in Building Bridges and Fostering Connections

The National Fish Passage Program is a national leader connecting watersheds and people. The program has decades of experience implementing infrastructure projects with partners. Fish passage project proposals can be initiated by any individual, organization, government, or agency. However, proposals must be submitted and completed in cooperation with a Fish and Wildlife Conservation Office. (Please note that fish passage fish passage
Fish passage is the ability of fish or other aquatic species to move freely throughout their life to find food, reproduce, and complete their natural migration cycles. Millions of barriers to fish passage across the country are fragmenting habitat and leading to species declines. The U.S. Fish and Wildlife Service's National Fish Passage Program is working to reconnect watersheds to benefit both wildlife and people.

projects being used for federal or state compensatory mitigation or required by existing federal or state regulatory programs are not eligible for funding through the National Fish Passage Program.) 


200 Million Dollar Investment in Rivers, Wildlife, and Communities

Clean free-flowing waterways are vital to wildlife, people, and ecosystems. But across the country, millions of barriers fragment rivers, block fish migration, and put communities at higher risk to flooding. The  Bipartisan Infrastructure Law Bipartisan Infrastructure Law
The Bipartisan Infrastructure Law (BIL) is a once-in-a-generation investment in the nation’s infrastructure and economic competitiveness. We were directly appropriated $455 million over five years in BIL funds for programs related to the President’s America the Beautiful initiative.
