Why Lake Tansi has no grade

Not Rated is not an F. It is EPA Integrated Reporting Category 3 — insufficient information. The water here may be excellent or poor; nobody has measured enough of it to say. Everything below that has been measured is still reported on this page.
Sampling is run by TDEC and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
