Why Little Red Reservoir has no grade

For Little Red Reservoir, no water-quality sampling on record for this lake.
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 NDEE and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
