There are four dams on the upper river at Upper Mill Pond, Lower Mill Pond, Southaven County Park, and the Sunrise Highway. Adjoining the river is the Wertheim National Wildlife Refuge. The river formed the western boundary of the massive Manor St. George under William "Tangier" Smith who in the 17th century owned most of modern-day Brookhaven south of the Sunrise Highway. A manor subsequently built by the Smith family is located in Shirley at the mouth.
