Why Lake Merriweather Goshen Dam Sidewall has no grade

For Lake Merriweather Goshen Dam Sidewall, no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years).
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.
