About This Route
Fontana Lake, nestled in the Great Smoky Mountains National Park along the southern terminus of the Appalachian Trail, offers exceptional freshwater scuba diving opportunities. Access the prime dive sites via the Deep Creek Trail, a moderate 2-mile hike from the Deep Creek Trailhead parking area off US-19 near Bryson City, North Carolina. This route connects directly to the AT's southern section, allowing hikers to combine trail adventures with submerged explorations of the lake's clear waters, sunken structures, and vibrant aquatic life including smallmouth bass, trout, and freshwater mussels. The lake formed by the Fontana Dam spans over 11,000 acres, with depths exceeding 400 feet, but stick to 30-60 foot dives in shallower coves for safety. According to NPS guidelines, this area boasts some of the most biodiverse freshwater ecosystems in the Southeast, perfect for PADI-certified divers seeking mountain scuba experiences.
Safety Considerations
Cold water temperatures dropping to 50°F (10°C) even in summer pose hypothermia risks; always monitor DAN's diving tables for repetitive dives at this elevation around 1,700 feet. Low visibility from silt (5-15 feet) demands buddy diving and surface marker buoys. Strong thermoclines and boat traffic in main channels require listening to VHF Channel 16 for alerts. Follow Leave No Trace by avoiding disturbance to mussel beds, protected under NPS regulations. Pre-dive briefings should cover nitrogen narcosis risks in deeper profiles and ascent rates no faster than 30 feet per minute. Local outfitter Mountains to Seas Scuba Adventures recommends full wetsuits for all dives here.
Essential Gear
Beyond standard scuba kit, pack a 5mm wetsuit from brands like Henderson or Bare, hooded vest for thermal protection, and a surface marker buoy (SMB) from Dive Rite. Include hiking boots for the trail approach, a dry bag for gear transport, and an inflatable PFD for surface swims. REI's Co-op drysack keeps regulators dry during the hike.
Emergency Tips
In case of decompression sickness, ascend slowly and contact DAN hotline at +1-919-684-9111 immediately; nearest chamber is in Asheville. Signal boats with a dive flag and whistle. For trail injuries, use Deep Creek Ranger Station at 828-488-2422.
