The Bass Lake Association is active with respect to monitoring the quality of our lake.  We currently have six test sites that provide a good snapshot of water conditions.

When we were with the MLA water testing programme, our lake specific data was analyzed by the Muskoka Lakes Association (MLA) and a full report was made available to all lakes, and their communities, each spring (following the sampling season). 

• Since COVID, the Bass Lake Association has gone our own way and is doing our own testing.
• We report regularly on this webpage, and in the weekly (May to October) Bass Lake Update.

Additional comprehensive information and reporting about Water Quality

and maintaining Water Quality is now available at our newest webpage titled Understanding Water Quality on Bass Lake

Spring 2021

New legislation came into effect on May 20th, 2021

• Bill 228: An Act to prohibit unencapsulated expanded or extruded polystyrene in floating docks, floating platforms and buoys
• It is now illegal to have exposed styrofoam in contact with the water.
• While it does not apply retroactively, and it does not specify floater mats, the same issues and concerns apply.

Please inspect any 'items' you might have that have styrofoam in contact with the water and remove/replace if they show signs of degradation.

• Clean Water Action (CA) has en excellent primer detailing the negative environmental impacts of 'syrofoam litter'

Information about testing your individual drinking water supply - the water coming from your tap - can be found in the Public Health section of the Community Connections page here at the Bass Lake Assocation website.
