Newport Creek is a tributary of the Susquehanna River in Luzerne County, Pennsylvania, in the United States.

The entire watershed of Newport Creek is considered by the Pennsylvania Department of Environmental Protection to be impaired.

Newport Creek then flows through Nanticoke, passing a mountain known as Honey Pot.

[4][5] In the 1970s, Newport Creek discharged an average of 82,564 pounds (37,450 kg) of acid into the Susquehanna River.

[6] At the headwaters of Newport Creek in Glen Lyon, the daily load of iron is 160.35 pounds (72.73 kg).

Downstream of the mouth of South Branch Newport Creek, the load is 27.84 pounds (12.63 kg) per day.

[2] The concentration of dissolved oxygen at the headwaters of Newport Creek ranges from 4.7 to 110.0 milligrams per liter.

[7] The sulfate concentration in the waters of the Newport Creek watershed was 340 parts per million in 1974.

[6] In the South Branch Newport Creek watershed, the daily load of sediment is 3,202.40 pounds (1,452.58 kg) per day.

[8] The watershed of Newport Creek is in the Allegheny Mountain section of the ridge and valley geological region.

[9] Nearly all (approximately 90%) of the Newport Creek watershed is occupied by interbedded sedimentary rock.

[2] There are five major sources of acid mine drainage in the Newport Creek watershed.

The Susquehanna #7 Mine Discharge, the largest source of pollution in the watershed, is 0.6 miles (0.97 km) from the mouth of the creek.

[7] The temperature in the area of the Newport Creek watershed ranges from −3.2 °C (26.2 °F) in January to 22.3 °C (72.1 °F) in July.

[5] On average, 43 inches (110 cm) of rainfall in the Newport Creek watershed per year.

In the watershed of South Branch Newport Creek, there is an average annual runoff of 1.03 inches (2.6 cm).

[4] Fairchild Pond and the Wanamie Reservoir are also present in the sub-watershed of South Branch Newport Creek.

Najaka Pond and Kielar Lake used to drain into Newport Creek or its tributaries, but mining in the watershed has intercepted their discharge.

[5] The Bloomery Forge was built on Newport Creek some time before January 1777 by Nathaniel Chapman, Joseph Beach, and Chris Alden.

A person named Chapman constructed a mill on the creek, which was eventually replaced one built by William Jackson.
