Okanagan River County Lake Quality
British Columbia, 8 lakes, measured by ENV with no A–F grades
Okanagan River County has 8 monitored lakes — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. No lake in Okanagan River County carries an A–F letter, and none can: the scale is scored against EPA reference conditions, which stop at the US border. The 8 monitored lakes below carry whatever clarity, phosphorus, and chlorophyll-a readings ENV 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.
