A reach of the creek above Lick Run is designated as Class A Wild Trout Waters.

It then turns west for a few miles and flows off Catawissa Mountain before eventually crossing State Route 2003, passing Mill Grove, and entering Locust Township.

[1] Roaring Creek joins the Susquehanna River 142.36 miles (229.11 km) upriver of its mouth.

Lick Run joins Roaring Creek 14.08 miles (22.66 km) upstream of its mouth.

[2] The concentration of alkalinity in Roaring Creek upstream of Lick Run is 9 milligrams per liter.

However, much of the watershed is rough and hilly and the creek flows through a valley surrounded by broken hills.

[6] Rocks in the watershed include claystones, conglomerates, sandstones, siltstones, and shales from the Devonian and Mississippian.

It is a reddish-brown soil that is slightly poorly or moderately well drained and is made from glaciated red shale and sandstone.

[12] The average annual rate of precipitation in the watershed of Roaring Creek ranges from 35 to 50 inches (89 to 127 cm).

[6] Roaring Creek is one of three major streams draining the southern part of Columbia County.

[4] A large tract of forested land on a ridge running from Moosic to the Susquehanna River passes through the watershed of Roaring Creek.

[12] Upstream of Lick Run, 13 percent of Roaring Creek is on public land that is open to access.

[12] The second-oldest mill in what is now Columbia County was built in a gorge on Roaring Creek, near its mouth, in the 1780s.

In 1856, the furnace produced 2350 tons of iron from ore on Montour Ridge, despite low water.

During this time period, major communities in the watershed included Roaring Creek and Bear Gap.

The two-span Esther Furnace Covered Bridge was built over the creek in Cleveland Township in 1905.

[18] A steel stringer/multi-beam or girder bridge carrying State Route 2012 was constructed over Roaring Creek in 1908 and repaired in 1996.

A two-span steel stringer/multi-beam or girder bridge carrying State Route 3003 was constructed across the creek southwest of Catawissa in 1950 and repaired in 2011.

A prestressed box beam or girders bridge carrying Pennsylvania Route 42 over the creek was built in 1959 south of Catawissa.

A prestressed box beam or girders bridge was built across the creek in 1974 south of Catawissa.

A steel stringer/multi-beam or girder bridge carrying Mill Road was built over the creek in 1985 and repaired in 2012.

[19] Wild trout naturally reproduce in the creek from its headwaters downstream to 11,154 feet (3,400 m) upstream of its mouth, a distance of 18.15 miles (29.21 km).

Eastern blacknose dace are the most common fish species in the watershed and were observed at 85 percent of the sites.

Fallfish, golden shiners, yellow bullheads, and American eels were all historically observed in the watershed, but were not found during the survey.

However, redside dace, creek chubsuckers, green sunfish, and fathead minnows were observed in the watershed for the first time during the 2003/2004 survey.

[4] The biomass of wild brown trout in section 02 of Roaring Creek was estimated in the early 2000s to be 9.53 kilograms per hectare.

[4] The Roaring Creek Bluffs are listed on the Columbia County Natural Areas Inventory.

[8] Other plant species in this area include hydrangea, fragile fern, maidenhair spleenwort, golden saxifrage.

[8] It is possible to canoe on 13.0 miles (20.9 km) of Roaring Creek, from Slabtown to the mouth during fast snowmelt or within three days of heavy rain.

Edward Gertler's book Keystone Canoeing describes the scenery as being "fair to good".
