From May to September, MountainTrue riverkeepers and volunteers collect weekly water samples from the Broad, French Broad, Elk, Green, Hiwassee, New, Notterly, and Watauga river watersheds. We process and analyze each sample and post the results to the Swim Guide website and mobile app before the weekend so you know where it’s safe to swim.
About our Swim Guide Program
MountainTrue’s Swim Guide bacteria monitoring program keeps you up-to-date with the latest water quality results for the most popular water recreation sites in the Southern Blue Ridge Mountains. You can trust our weekly Swim Guide results to keep you healthy this river season! 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 iloverivers.org. MountainTrue’s water quality program is powered by our volunteers, members, and donors like you.

For a donation of $30, you cover the staff time, supplies, and analysis to help sample a popular recreation area for one week. For $100, you help us sample three sites with change left over for a fourth. Businesses, organizations, and individuals can fully sponsor a Swim Guide sampling site for an entire year with a contribution of $1000, and we will recognize their generosity with a donor acknowledgment on the Swim Guide platform, the MountainTrue website, and through social media.
