Clear Creek carves a dramatic gorge through the Cumberland Plateau in Morgan, Cumberland, and Fentress counties, Tennessee, serving as a major tributary to the Obed Wild and Scenic River. The creek originates near the town of Clarkrange in Fentress County and flows generally westward through a deep sandstone canyon before joining the Obed River near Lancing in Morgan County. This 20-plus mile waterway has created spectacular geological features over millennia, with cliffs towering 200-400 feet above the streambed and massive sandstone boulders punctuating the riverbed.

The creek offers multiple paddling sections ranging from Class I-II flatwater suitable for overnight canoe trips to technical Class III-IV whitewater that demands advanced skills. The uppermost section from US 127 to Barnett Bridge spans approximately 20 miles of predominantly Class I-II water with occasional Class III rapids near the end, making it appropriate for extended touring trips. Downstream, the Barnett Bridge to Jett Bridge section (roughly 5 miles) maintains Class II character, while the Jett to Lilly stretch (2.5 miles) increases to Class II-III. The final section from Lilly Bridge to the Obed confluence presents the most challenging water, with Class III-IV rapids including the notable Jack's Rock, an eight-foot sloping drop.

Clear Creek is a rainfall-dependent stream that flows primarily during winter and spring months, typically November through April. Paddlers should expect cold water temperatures requiring appropriate thermal protection. The creek doubles in volume after joining the Obed, continuing downstream through additional rapids before reaching the Nemo takeout on the Emory River.

The gorge supports rich mixed mesophytic forests with hemlock, white pine, tulip poplar, and rhododendron thriving in the cool, moist canyon environment. Upland areas feature oak-pine forests typical of the Cumberland Plateau. The creek provides critical habitat for the federally endangered spotfin chub and purple bean mussel, along with smallmouth bass and bluegill for anglers.

Access points include bridges at US 127, Barnett Bridge (also called Waltman Ford), Jett Bridge on Highway 298, and Lilly Bridge on Ridge Road. The town of Wartburg serves as the primary gateway community, with Crossville and Jamestown providing additional services.

Clear Creek lies within the Obed Wild and Scenic River system, managed jointly by the National Park Service and Tennessee Wildlife Resources Agency. Parts of the watershed fall within Catoosa Wildlife Management Area, which closes during hunting seasons and February-March for resource protection. The area's sandstone cliffs attract rock climbers, and primitive backcountry camping is permitted with proper permits. The challenging whitewater, remote canyon setting, and limited access points demand self-sufficiency and solid river-reading skills from paddlers.
