Located in Western North Carolina, MountainTrue works to protect the places we share by championing resilient forests, clean waters, and healthy communities in the Southern Blue Ridge. With four in-house riverkeepers looking after the French Broad, Broad, Green, and Watauga rivers, MountainTrue is its own ecosystem of water defenders and protectors. 

From May to September, MountainTrue riverkeepers and volunteers collect weekly water samples from the Broad, French Broad, Elk, Green, Hiwassee, New, Nottely, and Watauga river watersheds. We process and analyze each sample and post the results to the Swim Guide platform before the weekend so you know where it’s safe to swim.

We use our testing data to track down sources of bacterial pollution and push for better policies to address the long-term issues affecting our rivers, lakes, and streams. To learn more about our clean water efforts, check out MountainTrue’s Clean Water Program is powered by our volunteers, members, and donors like you.
