Local Dam Removals
Restoring Shad to Our ‘Shed
The Watershed Association is moving forward on a project to open the Millstone River to migratory fish.
Since the late 18th century, dams constructed along the Raritan and Millstone Rivers have blocked American shad and other fish from swimming up the rivers to reproduce.
With support from American Rivers, Conservation Resources Inc., The Geraldine R. Dodge Foundation, the National Oceanic and Atmospheric Administration and the NJ Department of Environmental Protection, we are studying whether migratory fish can be restored with the removal of two small-head dams on the Millstone River: the Weston Causeway Dam in Franklin Township and Manville Borough, and the Blackwells Mills Dam in Franklin and Hillsborough townships.
By removing both dams, 14 more miles of river will be opened for migratory fish and recreational users, as well as allowing for restoration of stream corridors and wetlands.

Dam Removals on the Raritan River
As the Millstone River flows into the Raritan, several dams downstream had to be removed in order for migratory fish to reach our watershed.
The Watershed congratulates NOAA, NJDEP, El Paso Corporation, MWH Americas, Inc., as well as Carl Alderson, Dave Bean, and especially John Jengo of the Raritan River Restoration Initiative for their successful removal of the Calco Dam and Robert Street Dam on the Raritan River.
These dam removals are part of a larger effort to provide access for migratory fish species to habitat in the Raritan and Millstone Rivers. Dams pose a substantial impediment to migratory fish, inhibiting access to historical spawning grounds.
