Claystones, conglomerates, sandstones, siltstones, and shales all occur within the watershed. The creek flows through a gorge in its lower reaches, along the border between Columbia County and Montour County. Most of the watershed of Roaring Creek is in Columbia County, but small areas are in Montour County, Northumberland County, and Schuylkill County. More than 40 percent of the watershed is forested and nearly 40 percent is agricultural land. State game lands and state forests are also in the watershed. A total of approximately 3,500 people inhabit the watershed, as of 2000. The creek's drainage basin is a High-Quality Coldwater Fishery and a Migratory Fishery upstream of Lick Run. Downstream of Lick Run, the main stem is a Trout Stocked Fishery and Migratory Fishery. A reach of the creek above Lick Run is designated as Class A Wild Trout Waters. 31 species of fish were observed at 20 sites in the watershed in 2003 and 2004. Roaring Creek was historically known as Popemetang, but it was known as Roaring Creek by the late 1700s. Settlers such as Quakers first arrived in the area in the 1770s. In the 19th century, various mills and furnaces were constructed on the creek and several bridges were constructed. Agriculture was also a major industry in the watershed in the early 20th century.
