Yarmouth County Lake Quality

Nova Scotia, 78 lakes, measured by NSECC with no A–F grades

Yarmouth County has 78 monitored lakes, enough that within-county variation matters as much as the county average. Some are deep glacial basins, others are shallow agricultural-watershed waters, and the measurements reflect that mix. No lake in Yarmouth County carries an A–F letter, and none can: the scale is scored against EPA reference conditions, which stop at the US border. The 78 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.
