Chattooga River Watershed
Water Quality Data

The Chattooga River’s water quality is currently threatened by pollution in several of its tributaries. The Chattooga Conservancy is working to monitor streams and creeks throughout the watershed, identify potential sources of sediment and fecal coliform pollution, and find ways to mitigate these pollution sources.

From August to December 2019, this work was supported through a Wild & Scenic Rivers Stewardship Partnership grant from River Network, with funding provided by the U.S. Forest Service. If you would like to support our water quality monitoring efforts into 2020, please consider becoming a member or donating! Annual contributions from our members are extremely important to the success of our organization, allowing us to continue projects like this that lead to direct actions to protect the river we all love.

If you’re interested in volunteering to collect samples, please let us know! Call us at 706-782-6097 or email emily@chattoogariver.org.

Sample locations can be seen on our Chattooga Watershed Interactive Map.

The Georgia state water quality standards* for bacteria (fecal coliform) are as follows:
[Criteria based on at least 4 samples collected from a given site over a 30-day period.]

  • May- Oct: Not to exceed a geometric mean of 200 cfu/100 mL
  • Nov- April: Not to exceed a geometric mean of 1,000 cfu/100 mL; no single sample shall exceed 4,000 cfu/100 mL.

The South Carolina state water quality standards* for bacteria (E. coli) are as follows:
[Criteria based on at least 4 samples collected from a given site over a 30-day period.]

  • Not to exceed a geometric mean of 126/100 mL; no single sample shall exceed 349/100 mL.

*Water quality standards vary based on stream/ water classification. The listed standards apply to those in the Chattooga River watershed.
