Following months of research, the Environment Council and its partners at the Kawartha Land Trust and Fleming College (among others) have published a new map of our lakes  revealing the altered shoreline conditions and remaining natural shoreline. To read about this fascinating project and why it's important to the future health of our lakes, click below.


Human uses, particularly inappropriate development of lake shoreline properties over time, have taken a large toll on natural heritage, habitat and lake health. Ston(e)y and Clear lakes alone have over 2,000 developed waterfront properties. Now, a group of EC members is committed to addressing the need for shoreline and natural heritage protection for lakes via improved, proactive policy protection through the new Peterborough County Official Plan and through township by-laws and enforcement.

The Issues


Healthy Shorelines

Naturalized shorelines are a huge contributor to the health of our lakes. They diminish run-off, provide habitat and food for wildlife, prevent erosion, and improve our lake water quality. (And – bonus! – they inhibit geese.) To learn more about naturalized shorelines – why they're so important and how to create one on your own waterfront – click below.

 Starry stonewort

Starry stonewort (SSW) is an aggressive, invasive macro alga that has spread rapidly throughout the Kawartha lakes, having previously established itself in the Great Lakes, the St. Lawrence, Lake Simcoe and other lakes. While there is presently no way to rid our lakes of this damaging species it's vital that we learn to prevent its spread.
