Swim Guide


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!



About our Swim Guide Program

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 basins. We process and analyze each sample and post the results online before the weekend so you know if 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 iloverivers.org. MountainTrue’s water quality program is powered by our volunteers, members, and donors like you.
