Big Timber Creek is a 5.6-mile-long (9.0 km)stream in southwestern New Jersey
, United States
. It drains a watershed of 63 square miles (160 km2). A tributary of the Delaware River, it enters the Delaware between the boroughs of Brooklawn
and Westville, just south Gloucester City
and across from Philadelphia, Pennsylvania.The main stream and South Branch form about half of the border between Camden
and Gloucester counties.
Big Timber Creek flows roughly to the northwest. Two streams, the North Branch and the South Branch, join 5.6 miles (9.0 km) above its mouth to form the main stream. The South Branch is considered the source stream. Both branches are dammed at several points to form impoundments-no natural lakes occur along either branch.
