March 24, 2025 — If NOAA Marine Habitat Restoration Specialist Carl Alderson had his way, the story of dam removals on New Jersey’s Raritan River would be an epic film—Shad: The Movie.
Opening shot: Silvery fish throw themselves against a dam, unable to reach the other side. Battered and bloody, they try again, only to be swept downstream.
Voiceover: “In a world of uncertainty, scientists race against time to free the 1,110-square-mile Raritan River watershed from the bondage of obsolete dams to save a species. Will science and restoration be the heroes fish need to reach their ancient spawning grounds?”
Alderson’s film may be just an idea for now, but the story of the restoration of the Raritan River and its native migratory fish species is worth telling. The Raritan River Fish Passage Initiative, the brainchild of Alderson and other NOAA partners, has led to the removal of six dams. There are plans to remove dams or improve fish passage at nine other sites throughout the watershed.
This past fall, NOAA’s Office of Habitat Conservation awarded the Raritan Headwaters Association $2.3 million through the Infrastructure Investment and Jobs Act to remove the Rockafellows Mill Dam on the South Branch of the Raritan. This represents NOAA’s most significant investment in the watershed so far. Matching funds from the Cornell Dubilier Superfund settlement will also support this important project.
