South Brook is a tributary of Mehoopany Creek in Luzerne County and Wyoming County, in Pennsylvania, in the United States. It is approximately 6miles long and flows through Ross Township and Lake Township, Luzerne County, Pennsylvania in Luzerne County and Forkston Township in Wyoming County. The watershed of the stream has an area of 10.1sqmi. Wild trout are present in the stream and it has one named tributary, which is known as Opossum Brook.
South Brook begins in a wetland in Ross Township, Luzerne County. It flows northeast for several tenths of a mile and briefly enters Forkston Township, Wyoming County before turning south-southeast and reentering Ross Township, Luzerne County. The stream passes through a small unnamed pond and turns east, entering another wetland. Upon leaving this wetland, it enters Lake Township, Luzerne County and turns northeast for a few tenths of a mile before entering a third wetland. The stream then reenters Forkston Township, Wyoming County and meanders north through three more wetlands. It then turns northwest for a few miles, entering a deep valley. After more than a mile, its valley broadens and it continues flowing northwest for several tenths of a mile before receiving the tributary Opossum Brook from the left. The stream then turns north for a few tenths of a mile before reaching its confluence with Mehoopany Creek.
South Brook joins Mehoopany Creek 16.94miles upstream of its mouth.
South Brook has one named tributary, which is known as Opossum Brook. Opossum Brook joins South Brook 0.18miles upstream of its mouth, near Bellasylva, and drains an area of 5.13sqmi.
The elevation near the mouth of South Brook is 1532feet above sea level. The elevation near the stream's source is 2211feet above sea level. South Brook is a small and secluded stream. It flows in a generally northwesterly direction.
South Brook is one of five large brooks to descend from a high, flat-topped mountain that separates the Mehoopany Creek watershed from the Bowman Creek watershed. Going from southwest to northeast, South Brook is the first of these brooks. An especially high summit of the mountain runs from the headwaters of the stream to the headwaters of Henry Lott Brook.
In the late 1800s, coal was reported to appear at the headwaters of South Brook. The stream was described a s a "cold, clear mountain stream" in the late 1940s.
The watershed of South Brook has an area of 10.1sqmi. The mouth of the stream is in the United States Geological Survey quadrangle of Dutch Mountain. However, its source is in the quadrangle of Sweet Valley. The stream joins Mehoopany Creek near Bellasylva.
