About this location
Big Laurel Creek, downstream of the US 25/70 bridge in Madison County, has several “swimming holes” along a popular hiking trail. The section drops 200 feet in 3.7 miles, creating a series of class III and IV rapids that are prized by serious whitewater boaters. This trout stream flows into the French Broad River near Hot Springs, NC. Samples here are done in collaborative effort between MountainTrue and NC DEQ. NC DEQ takes samples on Mondays. MountainTrue takes samples on Wednesdays.
