Sandy Brook originates at
the South Shore Golf Course, flows south to Porzio’s Pond at Woodrow Road, and
joins the main stream of Lemon Creek in Bloomingdale Park. On the northern side
of the SIRT tracks, Lemon Creek becomes a major freshwater wetland system, with
marsh on either side. The creek becomes tidal at Bayview Avenue, with salt marsh
plants replacing freshwater ones. This final stretch runs through Lemon Creek
Park and empties into Raritan Bay.
