2019 Water Quality Report

The MLA Water Quality Initiative Report presents data collected at 180 locations during the summer of 2019 and compares it to data collected from 2002 to 2018.

The objectives of the MLA Water Quality Program are:  

  • To promote and encourage good stewardship of the lakes;
  • To monitor the long-term health of the lakes;
  • To identify adverse water quality trends at an early stage; and
  • To promote causation studies and remediation by the responsible authorities.  

In 2019, of the 55 Areas tested, there were 42 Areas with a green light, 9 Areas with a yellow light and 2 Areas with a red light. It is noted that the green, yellow and red Areas do not add up to the total number of Areas tested as there are 2 sites with only one or two years of data that are not rated yet. This year, 6 Areas changed from a green light to a yellow light, and 5 Areas changed from a yellow light to a green light.

Based on our analysis of the long-term data acquired to date, the water quality at most of the sampling locations remains good to excellent.
