MountainTrue will keep you healthy this river season.

MountainTrue’s Swim Guide bacteria monitoring program keeps you up-to-date with the latest water quality results for the Southern Blue Ridge Mountain’s most popular water recreation sites.

From May to September, MountainTrue volunteers collect weekly water samples from the Broad, French Broad, Elk, Green, Hiwassee, New, Notterly and Watauga river basins.

We process and analyze each sample and post the results online before the weekend so you know if it’s safe to swim. 

French Broad Riverkeeper Hartwell Carson takes a water sample in order to track down a source of bacterial pollution.
