Water Quality

Sandy Lake is a small lake with a more fragile ecosystem than most. For example, the lake takes 4 to 6 months to “flush” itself (depending on the research study referenced) so it is vulnerable to pollutant build-up. Dr. Patriquin’s research on water quality of the lake notes a signal (from the O2) of excess organic inputs from urbanization.

Approximately 600 acres of forest to the west and northwest of Sandy Lake is slated for housing development. This is the primary watershed area. It is from this side that most of the surface water enters the system. There is already dirty water entering there. Damaging organics and salts need to be reversed rather than added to. Since the 1970s, aquatic studies point to deterioration in oxygenation and increased salt loading of Sandy Lake related to urbanization and some clearcutting. Significant further settlement within the Sandy Lake watershed would make the lake inhospitable to the migratory fish, reduce wildlife diversity, as well as increase flooding downstream in the Sackville River flood plain.
