Black Creek (Nescopeck Creek)
Black Creek begins in Foster Township and flows southwest for less than a mile, passing though the community of Jeddo. The creek then enters Hazle Township, where it turns west and flows between two mountains, along the way passing through the community of South Ebervale. Further downstream, the creek leaves the two mountains and flows north of Hazleton, crossing Pennsylvania Route 940 and Pennsylvania Route 309, immediately after which it receives the tributary Little Black Creek. Slightly further downstream it enters West Hazleton, crossing Pennsylvania Route 93 and receiving the tributary Stony Creek, then crossing Interstate 81 in West Hazleton. Upon leaving West Hazleton, it reenters Hazle Township and continues west, soon crossing into Sugarloaf Township. Here for a few miles it flows roughly parallel to the border between Sugarloaf and Hazle townships, then turns southwest and enters Black Creek Township, passing briefly through Hazle Township. In Black Creek Township, the creek continues west, passing through communities of Gum Run, Derringer, Fern Glen and Gowen. At Gowen it turns north and flows through a water gap, with Buck Mountain to the west. On the other side of the water gap, the creek flows through Rock Glen and picks up the tributary Falls Run. Continuing north for a few miles, it picks up tributaries Barnes Run and Scotch Run, then turns northeast for slightly over a mile, reaching its confluence with Nescopeck Creek near the community of Tank.
Black Creek joins Nescopeck Creek 8.72 miles (14.03 km) upstream of its mouth.
The entire length of Black Creek is considered by the Pennsylvania Department of Environmental Protection to be impaired by acid mine drainage, the main sources of which are the Gowen and Derringer deep mine discharges; a number of smaller sources of abandoned mine drainage also contribute to impairment of the Black Creek watershed.
At the mouth of Black Creek, the daily load of aluminum is 636.98 pounds (288.93 kg). The iron and manganese loads at this site are 269.19 pounds (122.10 kg) and 457.05 pounds (207.31 kg) per day.

Geography and geology
The elevation near the mouth of Black Creek is 626 feet (191 m) above sea level. Elevation at the source is between 1,580 feet (480 m) and 1,600 feet (490 m). From its source to 9.5 miles (15.3 km) downstream, Black Creek's elevation decreases at a rate of 15.8 feet (4.8 m) per mile. For the next 7 miles (11 km), elevation decreases at a rate of 42.9 feet (13.1 m) per mile. From there to the mouth, elevation falls at a rate of 58.4 feet (17.8 m) per mile.
Black Creek's topography is described in a 1921 book as "mountainous". The upper part of the creek is in a broad valley, the lower part in a narrow valley. There are some swamps in the upper reaches. The channel is sinuous, flowing through rock formations of sandstone and shale which include coal.
An area known as Black Creek Flats, situated along the creek near Hazleton, is on the Luzerne County Natural Areas Inventory, although damaged by mining in the past.
There is a cataract on Black Creek near Interstate 81. There are also strainers on the creek.
Watershed and recreation
The watershed of Black Creek, with an area of 61.70 square miles (159.8 km2)., is in the Eastern Anthracite Middle Field, which is part of the Anthracite Upland Section of the ridge and valley physiographical province. Part of the watershed is drained by the Jeddo Tunnel, which discharges into Little Nescopeck Creek. Counties in the watershed include Luzerne County, Columbia County, and Schuylkill County. The creek's drainage basin is part of the lower North Branch Susquehanna River drainage basin.
It is possible to access the headwaters of Black Creek via Pennsylvania Route 309.
Black Creek flows through coal mining lands in its upper reaches and woodlands in its lower reaches. The creek is contaminated with runoff from Hazleton and coal mines, as well as with sewage and bacteria in its upper reaches.
It is possible to canoe on 14.6 miles (23.5 km) of Black Creek during the spring within one day of heavy rain. Edward Gertler describes the scenery along the creek as "very good to poor" in his book Keystone Canoeing. Difficulty largely ranges from 1 to 4- with areas of 6. Gertler describes the creek as a "little-known whitewater wonder". Difficult rapids are found in the lower reaches among other places.
In 1921, the three largest communities in the Black Creek watershed were Hazleton, Freeland, and West Hazleton, with populations of 25452, 6197 and 4715 respectively. Other communities in the watershed include Drifton, Jeddo, Rock Glen and Gowen, with 1921 populations of 2129, 377, 317 and 306 respectively.
In the early 1900s, the Pennsylvania Railroad followed Black Creek in its lower reaches. The Lehigh Valley railroad passed through the watershed's upper reaches. Main industries in the watershed at the time included coal mining and agriculture. Numerous tributaries of Black Creek were also used as water supply.
There are hemlocks in a glen in the lower reaches of Black Creek. Additionally, a number of species inhabit the Black Creek Flats, which are listed on the Luzerne County Natural Areas Inventory. These include the Common Roadside skipper, the Seepage Dancer, the Bog Copper, the Hartford Fern, the Elfin Skimmer, the Long Dash, the Eyed Brown, and the Aphrodite Fritillary.
