I’ve not paddled Buck Creek but I met the proprietors of Buck Creek Outfitters on a hike in Big South Fork.
Check out their link above. I know from my chat on the trail that the outfit knows what it is about: safe, informative, well-equipped, and good fun on the water.
Please contact an reputable outfitter or state information office to learn present conditions before paddling area waterways. Area rains create drastic swings in flow conditions.
