It rises in the Pinelands of southeastern Burlington County and flows generally south, through Bass River State Forest, and joins the Mullica from the north approximately {{convert|1|mi}} upstream from its mouth on Great Bay. The lower {{convert|2|mi}} of the river forms an arm of the estuary of the Mullica. The river is part of the watershed of the Mullica that drains an extensive unspoiled wetlands region of New Jersey. The majority of the land within the drainage basin is forested, and under state protection. Near the mouth and lower parts of the river, there is tidal influence.
