The Environment Council for Clear, Ston(e)y and White Lakes is a volunteer, non-profit conservation group.

Our goal is to preserve and enhance the sustainability of the local watershed environment for future generations of humans and wildlife.

Special Alert: Starry Stonewort


An aggressive invasive species arrives in the Kawartha Lakes

It is now confirmed that Starry Stonewort – a plant-like macro algae known to be in many northern US lakes has migrated to several lakes in Ontario, including Scugog, Simcoe, Couchiching . . . and Stony, where it is established in at least three areas: in the Lost Channel behind Fairy Lake Island – a paddlers’ paradise now almost completely filled in with SSW – Gilchrist Bay and Wildfire Golf Club.

This is an alarming development and one that will require a whole-lake action and education plan to contain the spread. Eradication at this time is not possible. Research into how to best deal with Starry Stonewort is ongoing, with no satisfactory removal technique recommended at this point. Signs have been posted in the Lost Channel discouraging people from passing through. (SSW spreads rapidly through fragmentation.) Conversations are taking place with property owners around Gilchrist Bay and Wildfire where signs conveying more detailed information are required. All of the lake associations are aware of the issue and will be involved in developing a plan to contain this dangerous macro algae. For more information, read the following brief presentation, prepared by Carol Cole for a recent Environment Council meeting. More information will be added here soon.

IMPORTANT: If you think the water around your shoreline is infested with Starry stonewort, contact us at starrystonewortec@gmail.com. We can help identify the species and recommend a safe course of action.

Year of the Natural Shoreline

It’s official! Environment Council has dubbed 2019 the YEAR OF THE NATURAL SHORELINE – a concept we kicked off with a late-May waterfront event at Camp Kawartha. Our guest speaker, Peterborough-based landscape architect Helen Batten of Basterfield & Associates Inc, demonstrated the importance of a vegetated buffer zone by the shoreline and explained why native plants with deep roots are so beneficial to lake water quality and wildlife habitat. Here’s Helen (right) at Camp Kawartha, talking about her redesign for the camp’s waterfront – work that will get underway this summer.

Facing Climate Change

Eutrophication (see video) is just one of the effects of climate change altering our lakes.


Making A Difference


Wondering how climate change affects our water?  So were we. So, with the support of the Ministry of the Environment, Conservation and Parks, Environment Council is conducting Dissolved Oxygen tests at three deep water sites on Upper Stoney, Stony, and Clear Lakes.

Old and faulty septic systems and holding tanks pollute lake water and pose significant threats to human health. They discharge nutrients such as nitrogen and phosphorus, and can contaminate surface and groundwater resources.

The EC recently highlighted the need for further environmental assessment of the development proposal for Pilgrim’s Rest, Upper Stoney, and we continue to monitor the large-scale expansion plans for the Lovesick Lake Trailer Park, immediately upstream from Stony Lake.

A natural shoreline is a healthy shoreline. That’s because they slow down nutrient runoff, reduce erosion, and provide food and shelter for fish and other wildlife. When you alter a natural shoreline – even with the best intentions, you upset a delicate – and essential – balance.
