Pardee Reservoir North Arm
Pardee Reservoir North Arm in Amador County, California is not rated for water quality — its monitoring record does not meet the evidence bar. Phosphorus: 4 µg/L. Chlorophyll-a (algae): 0.8 µg/L.
Why Pardee Reservoir North Arm has no grade
We grade a lake only when its monitoring record clears the evidence bar: at least three phosphorus or chlorophyll-a samples in the last ten years, scored against EPA National Lakes Assessment thresholds for this lake’s ecoregion. For Pardee Reservoir North Arm, no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years). Sampling here has recorded phosphorus and algae (chlorophyll-a), but not water clarity.
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 your state environmental agency and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
