Inverness County Lake Quality
Nova Scotia, 10 lakes, measured by NSECC with no A–F grades
Inverness County holds 10 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. No lake in Inverness County carries an A–F letter, and none can: the scale is scored against EPA reference conditions, which stop at the US border. The 10 monitored lakes below carry whatever clarity, phosphorus, and chlorophyll-a readings NSECC has published.
Many of the county's lakes are deep glacial basins, over 50 feet at their deepest point, which gives them thermal stratification and a buffer against summer warming.

NR = no A–F letter. The scale is scored against EPA reference conditions for a lake’s ecoregion, and those stop at the US border, so no amount of sampling produces a letter here. The measurements are published as the authority reports them, not a failing grade. How grading works.
