Cumberland County Lake Quality
Nova Scotia, 25 lakes, measured by NSECC with no A–F grades
There are 25 monitored lakes in Cumberland County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. No lake in Cumberland County carries an A–F letter, and none can: the scale is scored against EPA reference conditions, which stop at the US border. The 25 monitored lakes below carry whatever clarity, phosphorus, and chlorophyll-a readings NSECC has published.
Most of the county's monitored lakes are shallow, under 50 feet, which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed.

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.
