2014 Volunteer Water Testing Instructions

Complete instructions for the summer 2014 E.coli and Phosphorus testing are available on-line. Click here for the testing instructions with updated testing dates. Please note the additional instructions for Eastern Kawartha Lakes and SGS Lakefield Lab in Annex A and additional instructions for the Western Kawartha Lakes and CAWT Lab Lindsay in Annex B. The E.coli Log for this summer and sample letter for notice to property owners is at the end of the instructions. Have a great summer of testing at your lake.

The Algae of the Kawartha Lakes

A few remaining copies of the KLSA  2012 Algae Guide will be available for pick-up at the KLSA Fall Meeting and AGM,  Saturday September 27, 2014, 10:00 a.m., at the Lakehurst Hall. To view an on-line version click here. This project was made possible by a grant from the Ontario Trillium Foundation, which in 2010 supported KLSA in yet another water quality collaboration: a three-year program of research and education concerning algae in the Kawartha Lakes. This project was designed to increase our communities’ knowledge and capacity to protect the Kawartha watershed.

Milfoil Weevil Guide

Check out our  Guide to the Milfoil Weevil.  Can this tiny insect be the answer to controlling invasive Eurasian milfoil?  Click here for the full report. The Spring Meeting in Bobcaygeon, May 10th will have a presentation on the Big Cedar Lake Milfoil Project.

Algae: Too Much of a Good Thing? 

Click the left side link to download the 2011 Annual Report: Algae: Too Much of a Good Thing?  With 74  pages illustrated and packed with ground-breaking research on algae, milfoil weevils, sewage treatment plants,  lake water analyses, lake management planning, flow rates, shoreline landscaping, and much more.

Blue-Green Algae

If a blue-green algae bloom is suspected, the Peterborough County-City Health Unit recommends residents assume toxins are present, avoid using the water and call the Ministry of the Environment Spills Action Centre at 1-800-266-6060.  http://pcchu.peterborough.on.ca/

Water Soldier Invasive in Trent River

The invasive species Water Soldier plant has been found for the first time in Canada in the Trent Severn Waterway near the hamlet of Trent River.
Report all sightings of water soldier to the OFAH/MNR Invading Species Hotline at 1-800-563-7711  For more information go to

Colour maps of the Kawarthas

Check pages 39 to 43 of the 2009 Annual Report (left sidebar).  Developed for us by Fleming College students, these dandy new maps show geology of the watershed, and sources of peak water flow in summer and in winter.  How much water drains in from the low-phosphorus Canadian Shield land to the north? How much from the agricultural land to the south?  The results are surprising.  You can print these maps at home.

Lindsay storm sewer outfall report

Released April 2010. There’s a summary version in our 2009 Annual Report: A decade of stewardship (on the sidebar at left.)   Click here for the full scientific report prepared for KLSA by Fleming College students.  Is human sewage reaching the Scugog River, the source of Lindsay’s drinking water?

Who we are

How can we help you?

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.
