Why Mcgowan Lake has no A–F letter
The LakeQuality letter is scored against EPA National Lakes Assessment reference conditions for a lake’s ecoregion, and those stop at the US border. There is no reference condition for Nova Scotia, so the scale cannot be applied to Mcgowan Lake at any level of sampling. Sampling here has recorded water clarity and phosphorus, but not algae (chlorophyll-a).
This is not a gap in the monitoring record. NSECC publishes these measurements directly, and everything below that has been measured is reported on this page as NSECC reports it.
