RESOLVED December 13th, 2022


The Bass Lake Association is active with respect to monitoring the quality of our lake.  Historically we have tested six (6) sites that provide a good snapshot of water conditions.  For 2023, we are testing only four (4) sites as indicated in the second map (right).







We have reduced the number of test sites in recent years as they have shown no need for concern.  These include the watershed inflow point off Kendon Road that was tested for additional phosphorus load from the golf course (test pt 7 on the old map).  The results over the past 10 years have been benign and we have eliminated this as a test point.  We also eliminated testing around sites where there was concern of faulty septic beds (site 2 on the old map).  The recent septic study by the municipality has cancelled this need.

  • We report regularly on this webpage, and in the weekly (May to October) Bass Lake Update.
