Patchogue Lake Fish Passage Project


The Great Patchogue Lake Fish Passage Project seeks to reconnect the Patchogue River at its primary, head-of-tide barrier in the Village of Patchogue, with a focus on moving river herring and American eel. The project will result in a shovel-ready design that will provide the necessary readiness to pursue future construction funding.

River herring have been documented below the tidal barrier annually since 2006, and American eel have been documented for the past few migration seasons. It’s one of only about 30 streams on Long Island where remnant runs of the ecologically valuable fish still exist.

Access to the 40-acre Patchogue Lake, as well as the upstream riverine habitat and 26-acre Canaan Lake (where fish passage already exists), would provide freshwater habitat for river herring and eel. By fostering the growth of the river’s diadromous fish, the project seeks to complement restoration efforts on the neighboring Swan River (where a nature-like fishway was recently completed) and provide momentum for overall restoration efforts throughout the South Shore Estuary Reserve.

Seatuck has officially selected L.K. McLean Associates as the hired consultant to conduct site assessments, an alternatives analysis, and will design several different fish passage or dam removal options.  Once the Patchogue Lake Advisory Committee reviews the final design options and provide their feedback to Seatuck, the best design option will then be chosen.  Seatuck will then seek additional grant funding to hire a consultant to construct the fish passage based on the chosen design.
