Our Goals

To monitor lakes for yearly changes in phosphorus and E.coli levels.
To understand the dynamics of lake ecosystems and the causes of problems such as macrophyte (water plant) growth, including invasive species such as:

  • Eurasian milfoil
  • algae
  • zebra mussels
  • water pollution

To educate cottagers, year-round residents and the general public  about the importance of protecting the Kawartha Lakes.
To develop partnerships with government agencies, universities, colleges, cottage and ratepayer associations, and other environmental organizations to further the objectives of KLSA.

Who we are

The Kawartha Lake Stewards Association is a nonprofit, completely volunteer organization of cottagers and year-round residents formed to monitor the water quality of the Kawartha Lakes. Find out about who we are and what we do by going to KLSA Role January 2016

Founded in 2000, KLSA represents 24 cottager associations on more than a dozen lakes along the Trent Severn Waterway. KLSA partners with three levels of government as well as local businesses.

With help from studies by:

  • Dr Paul Frost, David Schindler Professor of Aquatic Science, Trent University
  • Dr. Eric Sager and colleagues at Trent University’s Oliver Ecological Centre, and
  • partnerships at Fleming College in Lindsay,

KLSA is doing ground-breaking research on invasive plant species, sources of nutrients in the lakes, and other areas of emerging concern. Public education has become a key part of our work. In the meantime, our core testing programs for bacteria and total phosphorus continue.

Every year we publish a well-received report describing our test results, research programs, and related information about our watershed. To view these reports, click on one of the links at the left of your screen. Please feel free to contact us with any questions or if you would like to become involved.

In 2008, Cottage Life magazine recognized our efforts with its Green Cottager award.  To read all about that click here.

KLSA is grateful for funding from the Ontario Trillium Foundation to support its new 2010-2012 algae research project in the Kawartha Lakes.
